Background:Left ventricular (LV) hypertrophy is an independent predictor of increased morbidity and mortality. However, whether assessment of LV mass and geometry by cardiac single photon emission computed tomography (SPECT) is feasible remains unclear.Material/Methods:We compared LV mass and geometry measured by cardiac SPECT to standard echocardiography in thirty consecutive patients (female 73%n mean age 22.64±17 years) who had both cardiac SPECT and echocardiography done less than 1 week apart.Results:There was good correlation between the LV mass (r=0.73, p
