ABMP MRI Physics case studies
ABMP MRI Physics · Put your knowledge to work in context.
The ABMP MRI Physics examination is a professional certification exam for medical physicists and related scientists who specialize in magnetic resonance imaging. It assesses the physics knowledge required to practice safely and effectively in clinical and research MRI settings. The ABMP MRI Physics case studies are 5 cases and about 3,288 words.
1Pediatric Abdominal Scan at 3 T: SAR-Limited T2 Strategy
A 9-year-old (28 kg) is scheduled for a liver/MRCP protocol on a 3 T scanner. The ordered sequences are a respiratory-triggered 3D T2-weighted FSE (echo train 120, refocusing flip 120 deg, 4 signal averages) and a single-shot T2 FSE.

A 68-year-old with a unilateral total hip arthroplasty (titanium stem, cobalt-chromium femoral head, polyethylene liner) needs an MRI for suspected periprosthetic infection. The implant is documented as MR-conditional at 1.5 T and 3 T under specified conditions, but the referral does not include the manufacturer's condition sheet.

A research protocol uses a 32-channel head coil at 3 T with a 3D MPRAGE accelerated 4-fold (2x2) in the phase and partition directions. Reconstructions show periodic banding and 'ghosting' replicas in the partition direction, most prominent at the skull base and posterior fossa.

A patient with frequent premature ventricular contractions (PVCs) undergoes a cardiac MRI. The ordered sequence is a retrospective ECG-gated segmented cine (segments of 12 views per cardiac phase, 30 phases, 1.5 T).
