Summary:

Description
  • Radiopaedia case ID: 74412
  • Image ID: 52052909
  • Image stack position: 97/150
  • Plane projection: short axis
  • Aux modality: cine SSFP
  • Modality: MRI
  • System: Cardiac
  • Findings: Findings: Heart rate:  68 bpm, body surface area (BSA) 2.03 m² Hematocrit:  0.39 Image quality: no limitations Morphology and functional analysis: Global hypokinesia pronounced in the thickened basal inferoseptal and inferior segments. Mildly increased left atrium. Thickened atrial septum. Persistent foramen ovale (PFO). Aortic valve insufficiency with a diastolic jet in the left ventricular outflow tract (LVOT). No intracavitary thrombi found. Myocardial tissue properties Increased myocardial signal intensity in the apical segments probably due to stagnant blood. Difficulties in nulling the myocardium with the look locker sequence. PSIR and IR-GE sequences show a dark blood pool and a subendocardial late gadolinium enhancement in a non-coronary arterial distribution with a lesser extent in the apical segments, together with a transmural enhancement of the basal segments. T1 mapping native: 1170-1250 ms [950-1060ms*], extracellular volume (ECV): ≥60% *reference range based on local data No pericardial enhancement. Minimal pericardial effusion. Impression: Non-obstructive left ventricular hypertrophy with mild systolic dysfunction. Cardiac MRI findings are consistent with cardiac amyloidosis. The high values in extracellular volume (ECV) and the distinct thickening of the interventricular septum favor ATTR over AL cardiac amyloidosis.
