Research topics from publications: CMR validation of left ventricular volumes and ejection fraction measured by the IQ-SPECT system in patients with small heart size. Representative work: BACKGROUND: The IQ-SPECT system is equipped with multifocal collimators and uses ordered-subset conjugate gradient minimization (OSCGM) as its reconstruction algorithm, achieving a shorter acquisition time than conventional SPECT. Left ventricular ejection fraction (LVEF) is overestimated by conventional SPECT in patients with small heart size. In this study, we compared IQ-SPECT with conventional SPECT and cardiovascular magnetic resonance (CMR) for the estimation of LVEF in patients with small hearts (males: EDV ≤ 60 ml, ESV ≤ 25 ml; females: EDV ≤ 45 ml, ESV ≤ 20 ml). METHODS: The study consisted of 49 consecutive patients (20 normal and 29 with small heart size) undergoing gated myocardi
