What Is The Radiology Assistant?

Updated

The Radiology Assistant (radiologyassistant.nl) is a free educational website for radiology professionals and trainees. It publishes evidence-based review articles, structured reporting guidelines, and teaching material across most major radiology subspecialties. It is aimed at radiologists, residents, and clinicians who need practical, image-rich guidance on diagnostic workup and reporting — not at patients seeking personal medical advice.

What the site covers

The homepage organizes content by organ system and subspecialty. Based on the site's own index, the main areas include:

Section Example topics
Abdomen Acute abdomen, appendicitis (US and CT pitfalls), CT in abdominal trauma, bowel ischemia, small bowel obstruction
Liver Characterization of liver masses, LI-RADS, segmental anatomy, incidentalomas
Pancreas Acute pancreatitis, pancreatic cancer CT staging, cystic lesions
Kidney Bosniak Classification 2019, solid renal masses
Gynaecology Acute abdomen in gynaecology, endometriosis MRI, cervical and endometrial cancer MR staging, ovarian cystic lesions
Prostate PI-RADS v2.1, prostate anatomy
Rectum Rectal cancer MR staging and restaging, perianal fistulas
Breast BI-RADS v2025 manuals (mammography and ultrasound), calcifications, breast cancer staging
Cardiovascular Cardiac and coronary anatomy, acute aortic syndrome, CAD-RADS 2.0, cardiomyopathy
Chest / Thoracic Thoracic ultrasound in acute abdomen, chest radiology for abdominal radiologists

The index also lists video lectures on selected topics, such as bowel ischemia and closed-loop obstruction.

How the content is structured

Most articles follow a consistent teaching pattern:

  • A clinical or diagnostic problem (for example, "Pitfalls in US and CT diagnosis of appendicitis")
  • Imaging findings with annotated examples
  • A practical approach or decision framework — often a roadmap or classification
  • Reporting guidance, where a standardized system exists (LI-RADS, PI-RADS, BI-RADS, CAD-RADS, Bosniak)

This makes the site useful in two situations: learning a topic from scratch, and checking a classification or reporting standard at the point of care.

Who it is for

  • Radiology residents preparing for exams or rotating through a subspecialty
  • General radiologists who want a quick, structured refresher before reporting an unfamiliar case type
  • Subspecialists checking the current version of a reporting system (for example, BI-RADS v2025 or PI-RADS v2.1)
  • Referring clinicians who want to understand what a radiology report is based on

What it is not

  • It is not a patient-facing symptom checker or a source of personal medical advice.
  • It is not a primary image archive or PACS — it is a teaching resource.
  • It does not replace local protocols, institutional guidelines, or formal training.

Practical notes

  • The site is in English and is organized as a browsable index rather than a search-first database, so navigating by organ system is usually the fastest route.
  • Several articles are explicitly versioned (for example, "BI-RADS v2025 Manual," "PI-RADS v2.1," "LI-RADS," "CAD-RADS 2.0"), so check the version label before applying a classification.
  • Some topics appear in more than one section depending on modality — for example, ovarian cystic lesions appear under both Gynaecology and Ovarium, and acute abdomen content spans Abdomen, Gynaecology, and Ultrasound.

If you are preparing for a case or an exam, start from the organ-system index, pick the article matching your modality, and use the embedded classification or roadmap as your reporting checklist.
