radiologyinfo.org

RadiologyInfo.org is a patient-focused information website that explains how imaging exams and treatments—such as X-ray, CT, MRI, ultrasound, nuclear medicine, and radiation therapy—are performed, what you may experience, and how to prepare. It is a reference resource, not a medical facility: the site directs specific medical questions and referrals to your physician. It is a reasonable place to start when you want plain-language background before a scheduled exam or a conversation with your doctor.

What the site covers

The site describes itself as containing about 300 procedure, exam, radiation safety, and disease descriptions spanning diagnostic and interventional radiology, nuclear medicine, radiation therapy, and radiation safety, with frequent updates. Its navigation reflects that scope: Tests and Treatments, Pediatric Care, Screening, Diseases and Conditions, Safety, and a Spanish-language section.

A practical feature is the set of preparation guides. The homepage highlights "How to Prepare for Your CT Exam," MRI, ultrasound, nuclear medicine, and X-ray guides, alongside report-reading articles such as "How to Read Your PET-CT Report" and "How to Read Your Mammography Report." If your main question is "what do I do before my scan," these pages are the most direct starting point.

Pediatric content is flagged separately—the site notes that some tests and treatments have special considerations for children and marks child-specific content with a hand symbol.

How trustworthy is the content?

The site states that all material is reviewed and approved by radiology experts from RSNA (Radiological Society of North America), ACR (American College of Radiology), and ASRT (American Society of Radiologic Technologists), as well as other professional radiology organizations. That review process is the main reason to treat it as a credible general reference rather than an anonymous health blog.

Two limits matter:

• It is general information, not advice for your case. The site explicitly says it is not a medical facility and asks you to contact your physician with specific medical questions or for a referral.
• It is not a provider directory in itself. To find a local imaging or radiation oncology provider, the site points to the ACR Accredited Facilities Database.

When to use it—and when not to

How to get the most from a visit

1. Identify your exam name from your appointment paperwork (for example, CT, MRI, or ultrasound).
2. Open the matching preparation page and note instructions such as what to wear or what to tell the staff—then confirm them with your imaging center, since site content is general and your facility's instructions govern.
3. Read the procedure description so you know what the exam involves and what you may experience.
4. If you have a report, use the relevant "How to Read Your..." article to familiarize yourself with common terms, then bring questions to your physician.
5. For anything specific to you, follow the site's own guidance: ask your physician.

A common pitfall is treating general preparation content as a substitute for the instructions your own facility gives you; the two can differ, and the facility's directions take precedence. Another is using the site to interpret whether a finding is serious—that judgment belongs to your doctor.

If you're new to Ahrefs and want to run your first SEO audit, the fastest path is: open Site Explorer, enter your target URL, review the Overview for a health snapshot, then dig into Organic Keywords, Top Pages, and Site Audit to find specific problems. From there, build a short prioritized to-do list instead of trying to fix everything at once.

This tutorial walks through that workflow using a realistic starting scenario, explains what the numbers mean, and shows how to turn findings into actions.

Before You Start: Pick a Narrow Scope

A common beginner mistake is auditing an entire large website on day one. The reports become overwhelming, and you can't tell which issues matter.

Instead, choose one of these starting points:

• A single important page (your homepage or a key product/service page)
• A small site (under ~50 pages, e.g., a personal blog or small business site)
• One section of a bigger site (e.g., /blog/)

For this tutorial, assume you're auditing a small business site with about 30 pages. The same steps scale up later.

You'll need an Ahrefs account to follow along. Ahrefs offers paid plans, and pricing and feature limits change over time, so check the current Pricing page for what's included in each tier before committing.

Step 1: Enter Your Target in Site Explorer

Site Explorer is Ahrefs' core tool for analyzing any website or URL.

1. Open Site Explorer from the top navigation.
2. In the search box, paste your domain (e.g., example.com).
3. Choose the Exact URL or Domain mode depending on scope. For a full-site view, use Domain or Prefix; for a single page, use Exact URL.
4. Press Enter.

You'll land on the Overview report. Don't try to absorb everything — focus on four numbers first.

Reading the Overview Snapshot

Important caveat: Ahrefs' traffic and keyword numbers are estimates based on its own data. They won't match Google Search Console or your analytics exactly. Treat them as directional, not absolute.

Step 2: See What You Already Rank For

Go to Organic Keywords in the left sidebar. This shows queries where your site appears in search results.

Sort by Traffic (descending) to see which pages bring the most estimated visitors. Then look for:

• Keywords ranking in positions 4–15 — these are often the easiest wins. A small content or on-page improvement can push them onto page one.
• Keywords with high volume but low position — potential opportunities if the topic is relevant.
• Irrelevant keywords — if you rank for something off-topic, it may signal thin or mismatched content.

Write down 5–10 of the position 4–15 keywords. These become your first optimization targets.

Step 3: Find Your Best and Weakest Pages

Open Top Pages. This ranks your URLs by estimated organic traffic.

Look for two things:

1. Your top performers — understand what topics and formats work. Can you create more content like this?
2. Pages with traffic but poor rankings — these may need on-page fixes (title, headings, internal links).

If a page gets zero traffic and targets a topic you care about, it's a candidate for a rewrite or consolidation.

Step 4: Run a Technical Site Audit

Now move to Site Audit. This crawls your site and flags technical and on-page issues.

1. Click Site Audit → New project.
2. Enter your domain and set crawl settings (default is usually fine for a small site).
3. Start the crawl and wait for it to finish.

Once complete, you'll see a Health Score and a list of issues grouped by category.

Which Issues to Fix First

Not all issues are equal. Prioritize in this order:

Ignore low-impact warnings (like minor meta description length) until the big items are handled.

Step 5: Turn Findings Into a To-Do List

You now have raw data. Convert it into a short, actionable list. Example:

1. Fix 3 broken links found in Site Audit.
2. Rewrite title tags on 5 pages with duplicate titles.
3. Improve 4 pages ranking in positions 6–12 by adding missing subtopics and internal links.
4. Remove or update 2 thin pages with no traffic.

Keep the list to 5–10 items max for your first audit. Finishing a short list beats starting a long one.

Common Beginner Mistakes

• Chasing every red flag. Site Audit flags many minor issues. Fix what affects rankings and users first.
• Trusting estimates as exact numbers. Ahrefs data is modeled, not measured from your analytics.
• Auditing a huge site too early. Start small to learn the interface.
• Ignoring search intent. A page can be technically perfect but still fail if it doesn't match what searchers want.
• Forgetting to re-crawl. After fixes, run Site Audit again to confirm improvements.

Where to Go Next

Once your first audit is done:

• Compare with competitors using Site Explorer's Competing Domains and Content Gap reports.
• Track keyword rankings over time with Rank Tracker.
• Explore backlink opportunities in the Backlinks and Link Intersect reports.
• Set up recurring Site Audit crawls so new issues surface automatically.

Your first audit isn't about perfection — it's about building a repeatable habit: enter a target, read the key reports, pick the highest-impact fixes, and act. Do that once a month and your site's health compounds.

RadiologyInfo.org covers roughly 300 descriptions spanning diagnostic and interventional radiology, nuclear medicine, radiation therapy, and radiation safety, plus sections on screening and on diseases and conditions. Each description explains how a procedure is performed, what you may experience, and how to prepare. The site is patient-facing and is not a medical facility, so it does not offer diagnosis or referrals; for those, it directs you to your physician or to the ACR Accredited Facilities Database to find a local imaging or radiation oncology provider.

How the content is organized

The site's navigation reflects its scope directly: Tests and Treatments, Pediatric Care, Screening, Diseases and Conditions, Safety, and a Spanish-language section. A spotlight area surfaces timely material—for example, breast cancer awareness content in October—alongside recently posted preparation guides and report-reading articles.

Tests and treatments

This is the largest area. It covers:

• Diagnostic radiology — X-ray, CT, MRI, ultrasound, mammography, and PET-CT, among others.
• Interventional radiology — image-guided procedures.
• Nuclear medicine — exams that use radioactive tracers.
• Radiation therapy — treatment-oriented content for radiation oncology.

For each exam type, the site publishes a preparation guide. The homepage lists dedicated "How to Prepare for Your..." articles for CT, MRI, ultrasound, nuclear medicine, and X-ray exams, which is a useful shortcut if you already know your appointment type and just need the instructions.

Screening and diseases and conditions

Separate sections address screening exams and condition-specific content, so you can approach the site either from "what test am I having?" or from "what condition is being evaluated?" The pediatric section flags child-specific considerations; the site marks child-specific content with a hand icon so you can spot it while browsing.

Safety

A dedicated safety section covers radiation safety topics. This matters if your question is about dose, risk, or protective measures rather than about a specific exam.

Reading your report

Beyond exam descriptions, the site publishes guidance on understanding results: "How to Read Your Mammography Report," "How to Read Your PET-CT Report," and a general "Reading Your Radiology Report" article. It has also posted guidance on patient-friendly AI-generated summaries of radiology reports. These are explanatory articles, not a service that interprets your personal report.

Who reviews the material

All content is reviewed and approved by radiology experts from RSNA, ACR, and ASRT, along with other professional radiology organizations, and the site states it is updated frequently with new information. That review structure is the main reason to use it over general health sites when you need procedure-specific detail.

What it does not do

The site explicitly notes it is not a medical facility. It will not answer questions about your specific case or refer you to a named radiologist. For those needs it points you to your physician, and for finding a provider it points you to the ACR Accredited Facilities Database. Use RadiologyInfo.org to understand what an exam involves and how to prepare; use your care team for decisions about your own imaging.

RadiologyInfo.org offers patient-oriented articles that explain how to read common radiology reports—including dedicated guides for PET-CT and mammography reports—alongside general guidance on reading your report and on patient-friendly AI-generated summaries. It is an educational resource, not a medical facility, so it helps you understand report language and prepare questions before discussing results with your physician.

What the site provides for report reading

RadiologyInfo.org is produced with review and approval by radiology experts from RSNA, ACR, and ASRT, as well as other professional radiology organizations. Its report-reading content sits within a broader library of roughly 300 procedure, exam, radiation safety, and disease descriptions covering diagnostic and interventional radiology, nuclear medicine, radiation therapy, and radiation safety.

The report-related resources listed on the site include:

• How to Read Your PET-CT Report — a procedure-specific walkthrough of what a PET-CT report contains.
• How to Read Your Mammography Report — a procedure-specific guide to mammography report structure and terminology.
• Reading Your Radiology Report — general guidance on approaching a radiology report.
• Guidance for Patient-Friendly AI-Generated Summaries of Radiology Reports — explains how AI-generated plain-language summaries of reports should be understood.

How to use it before talking to your physician

1. Identify the exam type named on your report (for example, PET-CT or mammography).
2. Open the matching "How to Read Your…" article if one exists; otherwise start with "Reading Your Radiology Report."
3. Match the sections of your report to the article's explanations of what each part typically describes.
4. Write down terms you don't understand and bring them to your physician.
5. If you received an AI-generated summary, read the site's guidance on those summaries before relying on the wording.

The expected result is a clearer sense of what your report covers and which questions to raise—not a diagnosis. The site explicitly states it is not a medical facility and directs specific medical questions and referrals to your physician.

What it does not do

RadiologyInfo.org does not interpret your individual results, provide a diagnosis, or replace a conversation with your clinician. Its value is in explaining how exams are performed, what you may experience, how to prepare, and how report content is typically organized. For finding a local imaging or radiation oncology provider, the site points to the ACR Accredited Facilities Database rather than offering its own lookup.

Practical note

The site states that, to help ensure current and accurate information, copying is not permitted but linking to the site is encouraged—so share links rather than reproduced text when passing guidance to family members.

RadiologyInfo.org does not list or refer providers itself. To find an accredited imaging or radiation oncology provider in your community, use the ACR Accredited Facilities Database, which the site points to for this purpose. RadiologyInfo.org states plainly that it is not a medical facility, so it cannot book appointments, give referrals, or answer questions about your own case. For those, contact your physician.

What RadiologyInfo.org Does and Doesn't Do

The site is an educational resource maintained with expert review from RSNA, ACR, ASRT, and other radiology organizations. It describes how roughly 300 procedures, exams, safety topics, and conditions work, including x-ray, CT, MRI, ultrasound, nuclear medicine, and radiation therapy, and covers what you may experience and how to prepare.

Step by Step: Locating a Provider

1. Start on RadiologyInfo.org. The site's welcome text directs community members to the ACR Accredited Facilities Database to locate a medical imaging or radiation oncology provider.
2. Open the database. Follow that link to reach the ACR facility search.
3. Search your area. Enter your location to see accredited facilities nearby. Accreditation signals that a facility has met ACR standards, which is the reason the site routes you here rather than to an arbitrary list.
4. Confirm details with the facility. The database identifies facilities; scheduling, insurance, and preparation instructions come from the provider. Call before you go.
5. Bring your questions to your physician. If you are unsure which exam you need or how to interpret a result, that conversation belongs with your doctor, not the website.

Expected result: a shortlist of accredited facilities in your community that you can contact directly.

Common Sticking Points

• Expecting a referral from the site. It explicitly does not provide one. The database is a locator, not a referral service.
• Looking for prices or booking. The site's material covers procedures and preparation, not pricing or appointments; ask the facility.
• Confusing education with advice. Pages explain exams in general terms. They are not a substitute for your physician's guidance on your specific situation.

Pairing the Search with Preparation Pages

Once you have a facility and an exam scheduled, the site's preparation articles are the practical next stop. Recently posted guides cover how to prepare for CT, MRI, ultrasound, nuclear medicine, and x-ray exams, plus how to read PET-CT and mammography reports and how to read your radiology report generally. Reading the relevant one before your appointment helps you arrive ready and understand what follows.
