Late Enhancement of Cardiac MRI in Patients with Suspicious Cardiacamyloid

【Abstract】 Objective To determine the differential diagnostic value of myocardial delayed enhancement of cardiac MRI on suspicious cardiac amyloid.Methods Six patients with suspicious cardiac amyloidosis were scanned on a Siemens 3.0 T scanner. Late gadolinium enhancement (LGE) was performed 5-15 min after bolus injection with gadolinium (0.15 mmol/kg) in the patients. Their ventricular function, morphology and LGE characteristics were analyzed. Results Cardiac amyloid was confirmed in 4 cases, in which LGE showed concentric subendocardial enhancement. The 2 cases without such LGE type were also excluded from cardiac amyloid by clinical pathology. Conclusion Late gadolinium enhancement of cardiac MRI is an effective diagnostic tool for differentiating cardiac amyloid.
