EnglishWhat Is RadiologyInfo.org?
Updated
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
| Your situation | Is RadiologyInfo.org a good fit? |
|---|---|
| You have an exam scheduled and want to know how to prepare | Yes—start with the preparation guide for that exam |
| You received a report and want to understand the terminology | Yes—the report-reading articles are designed for this |
| You want background on a procedure before consenting | Yes, as a primer to discuss with your doctor |
| You have symptoms and want a diagnosis | No—contact a physician |
| You need a radiologist referral or a local facility | Use your physician or the ACR facilities database |
| You need advice tailored to your medical history | No—this requires your own clinician |
How to get the most from a visit
- Identify your exam name from your appointment paperwork (for example, CT, MRI, or ultrasound).
- 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.
- Read the procedure description so you know what the exam involves and what you may experience.
- 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.
- 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.
