METHODS We have developed a protocol, termed "temporal image fractionation," in which static myocardial perfusion SPECT studies are acquired as three-interval dynamic studies (three temporal frames, each consisting of a full projection set), utilizing continuous alternating detector rotation and a multi-detector camera. The frames are individually examined(More)
BACKGROUND The incremental prognostic value of post-stress left ventricular ejection fraction (EF) and volume over perfusion has not been investigated. METHODS AND RESULTS We identified 1680 consecutive patients who underwent rest Tl-201/stress Tc-99m sestamibi gated single photon emission computed tomography (SPECT) and who were followed-up for 569+/-106(More)

UNLABELLED This study validates a new quantitative perfusion SPECT algorithm for the assessment of myocardial perfusion. The algorithm is not based on slices and provides fully 3-dimensional sampling and analysis independent of assumptions about the geometric shape of the left ventricle. METHODS Radiopharmaceutical- and sex-specific normal limits and(More)
developed and validated an automatic and accurate method to measure left ventricular ejection fraction (LVEF) from @Tc sestamibi gated SPECT images (7). We also successfully applied the same method to low-count images resulting from a standard @Tc-sestaimbi injection and a fast (6.7-mm) gated SPECT acquisition protocol (8), with the ultimate goal of(More)
UNLABELLED Left ventricular (LV) segmentation, including accurate assignment of LV contours, is essential for the quantitative assessment of myocardial perfusion SPECT (MPS). Two major types of segmentation failures are observed in clinical practices: incorrect LV shape determination and incorrect valve-plane (VP) positioning. We have developed a technique(More)
The Industrial Light & Magic team discusses the range of challenges presented by bringing the latest installment in the storied "Star Wars" series to life. Utilizing a seamless blend of practical effects, sets, locations, and cutting-edge digital animation and visual effects, the team summarizes how they created an array of the film's 2,100(More)
