Question 1 of 10
Brain MRI montage demonstrating extensive white-matter hyperintensity including characteristic anterior temporal involvement.

A 43-year-old patient has migraine with aura, recurrent subcortical ischemic events, and a parent with early-onset stroke. Brain MRI is shown. Which diagnosis is most likely?

Question 2 of 10
Cardiac MRI montage demonstrating a rounded left atrial soft-tissue mass attached near the interatrial septum with heterogeneous enhancement.

A 53-year-old patient with episodic positional dyspnea and presyncope undergoes cardiac MRI. The images are shown. Which diagnosis best explains the intracardiac mass?

Question 3 of 10
Axial noncontrast head CT showing a crescentic extra-axial collection along the left cerebral convexity with local mass effect.

A 78-year-old patient receiving anticoagulation develops gradually worsening confusion and gait imbalance several weeks after a minor fall. Noncontrast head CT is shown. Which diagnosis is most likely?

Question 4 of 10

A 44-year-old patient receiving natalizumab for multiple sclerosis develops progressive cognitive impairment and hemiparesis over several weeks. MRI shows asymmetric confluent subcortical T2-FLAIR hyperintensity involving U fibers, minimal mass effect, and no significant enhancement. Which diagnosis is most likely?

Question 5 of 10
Neonatal abdominal radiograph showing two prominent upper-abdominal gas-filled structures with no visible distal intestinal gas.

A newborn develops persistent bilious vomiting within hours of birth. The abdominal radiograph is shown. Which diagnosis is most likely?

Question 6 of 10

A patient with prior Roux-en-Y gastric bypass presents with acute intermittent abdominal pain and vomiting. CT shows clustered small-bowel loops with twisting of mesenteric vessels and fat around a central point. Which diagnosis is most concerning?

Question 7 of 10

A patient with cirrhosis undergoes technically adequate multiphasic liver MRI. A 24-mm observation demonstrates nonrim arterial-phase hyperenhancement and nonperipheral washout on the portal venous phase, without features suggesting a non-HCC malignancy. Which LI-RADS category is appropriate?

Question 8 of 10

A 63-year-old patient has progressive hand clumsiness, gait imbalance, hyperreflexia, and bilateral upper-extremity paresthesias. Cervical radiographs show multilevel degenerative change. Which examination best evaluates clinically suspected cervical spondylotic myelopathy?

Question 9 of 10
Axial abdominal CT showing a small pericolonic fat-density ovoid lesion with a thin dense rim and surrounding stranding.

A 44-year-old man presents with sharply localized left lower-quadrant pain, minimal systemic symptoms, and nearly normal inflammatory markers. Contrast-enhanced CT is shown. Which diagnosis best explains the focal abnormality?

Question 10 of 10

A patient with chronic pancreatitis develops new upper gastrointestinal bleeding. Arterial-phase CT shows a round intensely enhancing focus within the pancreatic tail region that matches arterial blood pool on all phases. Which diagnosis is most likely?
