What Tests, Treatments and Safety Topics Are Covered on RadiologyInfo.org?

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.
