Abstract

Purpose: This study was done to estimate delayed enhancement (DE) contrast resolution of infarcted myocardium (IM) relative to intraventricular blood (IB) and viable myocardium (VM) using gadobenate dimeglumine (Gd-BOPTA). Materials and methods: After approval from the Ethics Committee, we retrospectively evaluated 21 consecutive patients (61±10 years) with a healed myocardial infarction who underwent 1.5-T magnetic resonance (MR) imaging using an inversion-recovery-prepared turbo gradient-echo sequence 10 minutes after injection of 0.1 mmol/kg of Gd-BOPTA. Signal intensity (SI) was measured in arbitrary units (au) for IM, IB, VM, and outside the patient. Contrast-to-noise ratio (CNR) was calculated for IM to IB and IM to VM. Seven consecutive patients (59±6 years) with a healed myocardial infarction studied with similar technique but with 0.1 mmol/kg of gadoterate meglumine (Gd-DOTA) served as the control group. The Mann-Whitney U test was used to compare groups. Results: Mean SI of IM was 44±16 au for Gd-BOPTA and 20±6 au for Gd-DOTA (p
