What Specific Guidelines and Disease Reviews Are Available on The Radiology Assistant?

Updated

The Radiology Assistant (radiologyassistant.nl) is a free educational radiology site organized by organ system, offering disease reviews and structured reporting guidelines. Its content is most useful if you want practical, protocol-oriented guidance tied to major classification systems — such as BI-RADS for breast imaging, PI-RADS for prostate MRI, LI-RADS for liver lesions, and CAD-RADS for coronary CT — rather than a general textbook. The site also covers acute and emergency imaging topics and notes version updates in some titles, such as BI-RADS v2025 and a rectal cancer MR staging update dated 2026.

Structured Reporting Guidelines

These pages translate major reporting systems into practical use:

System Topic Area
BI-RADS (v2025) Breast — separate manuals for mammography and ultrasound
PI-RADS v2.1 Prostate cancer on MRI
LI-RADS Liver imaging
CAD-RADS 2.0 Coronary artery disease on CT
VI-RADS Bladder cancer
Bosniak Classification 2019 Renal cystic lesions

Disease Reviews by Organ System

Abdomen and GI

  • Acute abdomen, appendicitis (US findings, plus pitfalls in US and CT diagnosis)
  • CT in abdominal trauma; practical approach to acute abdomen
  • Bowel ischemia, CT patterns of bowel wall thickening, closed-loop small bowel obstruction
  • Crohn's disease (role of MRI and ultrasound), small bowel tumors, GI foreign bodies
  • Anal cancer and staging; abdominal wall hernias

Hepatobiliary and Pancreas

  • Characterization of liver masses, common liver tumors, incidentalomas, segmental anatomy
  • Common bile duct stones (ultrasound), gallbladder obstruction, gallbladder wall thickening
  • Acute pancreatitis, pancreatic cancer CT staging 2.0, pancreatic cystic lesions

Genitourinary and Gynecology

  • Solid renal masses; characterization of adrenal lesions
  • Ovarian cystic lesions with a roadmap for evaluation; acute abdomen in gynecology (ultrasound)
  • Endometriosis (MRI), cervical and endometrial cancer MR staging, Müllerian duct anomalies

Oncology and Pelvis

  • Prostate cancer (PI-RADS v2.1) and prostate anatomy
  • Rectal cancer MR staging and restaging (update 2026); perianal fistulas

Chest, Cardiovascular, and Breast

  • Thoracic ultrasound in acute abdomen; chest radiology for abdominal radiologists
  • Cardiac anatomy, coronary anatomy and anomalies, acute aortic syndrome, thoracic aorta measurement, TAVI/TAVR, vascular anomalies
  • Breast: BI-RADS manuals, calcifications differential, breast cancer staging and treatment, implants and prostheses, male breast pathology, breast MRI and ultrasound

How to Choose What to Read

  • For a specific reporting standard (e.g., you need to assign a PI-RADS or BI-RADS category), start with the corresponding guideline page.
  • For a clinical problem (e.g., right lower quadrant pain), use the organ-system review, such as the appendicitis US/CT pages.
  • For updated protocols, check titles that carry a version or year, since these signal the most current content.

Because the site is organized as a topic index rather than a single course, the fastest route is to scan the organ-system headings and open the page matching your case or reporting need.
