Is The Radiology Assistant free to access?

Updated

The Radiology Assistant (radiologyassistant.nl) is an open educational website: the material shown on its home page is presented as a public teaching resource, and nothing in the available site information indicates a paywall, subscription, or login requirement. You can expect to reach the topic pages directly. That said, the site data available here does not include an explicit pricing or access statement, so treat "free and open" as the working assumption rather than a confirmed policy — if a page ever asks for payment or registration, that page's own terms govern.

What the site is

The Radiology Assistant is a radiology education site organized by organ system and clinical problem. Its home page reads like a curriculum index rather than a product page: each entry is a teaching article or review, often built around a reporting system or a practical diagnostic approach.

What you can read without paying

Based on the home page listing, the content spans most of diagnostic radiology. Representative examples:

Area Example topics listed
Abdomen Acute abdomen, appendicitis US pitfalls, CT in abdominal trauma, bowel ischemia, closed-loop obstruction
Liver / pancreas Characterization of liver masses, LI-RADS, incidentalomas, acute pancreatitis, pancreatic cancer CT staging
GU / pelvis Bosniak Classification 2019, solid renal masses, PI-RADS v2.1, ovarian cyst roadmap
Chest / cardiovascular Cardiac anatomy, coronary anomalies, CAD-RADS 2.0, acute aortic syndrome, TAVI/TAVR
Breast BI-RADS v2025 manuals (mammography and ultrasound), breast MRI, male breast
Oncology staging Rectal cancer MR staging and restaging (2026 update), cervical and endometrial cancer MR staging, anal cancer staging

Several entries are explicitly structured as guidelines or classification manuals — BI-RADS, LI-RADS, PI-RADS, Bosniak, CAD-RADS — which is the main reason people bookmark the site.

How to use it

  1. Open radiologyassistant.nl.
  2. Pick the organ system or the named classification you need (for example, "BI-RADS v2025 Manual – Ultrasound").
  3. Read the article as a reference while you are reporting or preparing for a case.

Expected result: a structured review with imaging examples and diagnostic criteria, not a quiz or a course with progress tracking.

Practical caveats

  • Version drift. Several pages carry version numbers or dates (BI-RADS v2025, PI-RADS v2.1, LI-RADS, CAD-RADS 2.0, rectal cancer update 2026). Check the version on the page against the one your department uses before quoting criteria.
  • Not a substitute for local protocol. These are educational reviews; your institution's reporting templates and follow-up rules still take precedence.
  • Language. The site is in English.
  • Access details. No pricing, login, or registration information is available in the site data here, so do not assume an account is needed — and do not assume a specific license for reuse either. If you plan to reproduce figures in teaching material, check the site's own terms.

Who gets the most out of it

Residents preparing for boards or on-call, radiologists who want a quick structured refresher on a classification system, and clinicians who need to understand what a report is based on. If you want a single free reference that covers both "how to approach this finding" and "how to score it," this site is built for exactly that.
