Content Domains

The exam is divided into four content domains based on the ARDMS 2017 Job Task Analysis:

Domain 1: Anatomy, Perfusion, and Function (30%)

• Liver (16-24%): Normal anatomy, variants, Couinaud segments, hepatic vasculature
• Kidneys/Urinary (16-24%): Renal anatomy, collecting system, ureters, bladder
• Gallbladder/Biliary (10-18%): GB anatomy, bile ducts, pancreatic duct
• Abdominal Vascular (7-15%): Aorta, IVC, portal system, hepatic veins
• Pancreas (6-14%): Pancreatic anatomy, ductal system
• Scrotum (3-7%): Testicular anatomy and vascular supply
• Retroperitoneum (3-7%): Adrenals, lymph nodes, psoas muscles
• Spleen (1-5%): Splenic anatomy and vasculature
• GI Tract (1-5%): Bowel wall layers, appendix
• Abdominal Wall/Superficial (1-5%): Hernias, abdominal wall structures
• Neck (1-3%): Thyroid, parathyroid
• Prostate (1-2%): Prostatic anatomy

Domain 2: Pathology, Vascular Abnormalities, Trauma, and Postoperative Anatomy (42%)

• Liver pathologies (fatty liver, cirrhosis, hemangioma, HCC, metastases)
• Biliary pathologies (cholecystitis, cholelithiasis, cholangiocarcinoma)
• Renal pathologies (cysts, tumors, hydronephrosis, stones)
• Pancreatic pathologies (pancreatitis, pseudocysts, adenocarcinoma)
• Vascular abnormalities (AAA, stenosis, thrombosis)
• Trauma assessment (FAST exam, solid organ injury)
• Postoperative evaluations (TIPS, transplant, surgical changes)

Domain 3: Abdominal Physics (8%)

• Ultrasound principles (frequency, resolution, attenuation)
• Artifacts (shadowing, enhancement, reverberation, aliasing)
• Doppler physics (spectral Doppler, color Doppler, spectral analysis)
• Image optimization (TGC, focal zones, harmonics)
• Bioeffects and safety (ALARA, MI, TI)

Domain 4: Clinical Care, Practice, and Quality Assurance (20%)

• Patient preparation and positioning
• Scanning techniques and protocols
• Image documentation and measurement
• Quality assurance and phantom testing
• Infection control and safety standards
• HIPAA and professional ethics

Study Recommendations

1. Master Normal Anatomy: Before studying pathology, ensure thorough knowledge of normal sonographic anatomy and variants
2. Understand Hemodynamics: Study Doppler principles and normal vascular flow patterns
3. Review Physics: Focus on image optimization, artifacts, and bioeffects
4. Practice Recognition: Study characteristic sonographic appearances of common pathologies
5. Learn Measurements: Know normal values and measurement criteria for common conditions
