Introduction Despite the consistently high endocardial border visualization achieved with cine MR imaging, visual identification of developing wall motion abnormalities may be challenging in hypertrophied hearts.
Purpose To examine the influence of left ventricular hypertrophy and geometry on the diagnostic accuracy of wall motion and perfusion analysis during high dose dobutamine stress magnetic resonance (DSMR).
Methods Combined wall motion (DSMR) and perfusion imaging (DSMRP) was performed in a single session in 156 patients scheduled for invasive coronary angiography. Patients were classified into four categories based on LV mass (normal ≤81 g/m2 in men, ≤62 g/m2 in women) and relative wall thickness (RWT, normal
