introduction: it is recommended that the physician apply at least a semi-quantitative segmental scoring system in myocardial perfusion spect.  we aimed to assess the agreement between automated semi-quantitative analysis using qps (quantitative perfusion spect) software and visual approach for calculation of summed stress  score (sss), summed rest score (srs) and summed difference score (sds). ...

introduction: motion of the patient during myocardial perfusion spect could potentially results in false perfusion defects. the effect of different reconstruction methods on these artifacts is not studied. clarification of the relation between the extent, severity and duration of motion with the resultant artifacts may be helpful in designing special soft wares for motion correction. this study...

imatinib is an orally administered tyrosine kinase inhibitor which inhibits the bcr-abl protein-tyrosine kinase with high selectivity. imatinib is rapidly absorbed from the gut, after oral intake and has an almost absolute bioavailability of 98%. the metabolism of imatinib is mediated by the cytochrome p450 (cyp) isoenzymes in the liver and gut wall. cgp74588 is a major active metabolite of ima...

background: there is a fundamental correlation between follicles and endometrium in intracytoplasmic sperm injection (icsi) cycles. objective: to assess the relation between perifollicular perfusion and sub endometrial parameters in doppler ultrasonography and outcome of in icsi cycles. materials and methods: in this prospective deh1ive pilot study 10 patients were enrolled. strict inclusion cr...

Physiological perfusion asymmetries in the lower limb are known, although poorly understood, as reported plantar pressure and stance. This preliminary study aims to explore potential relationships between variables humans. A convenience sample of eight healthy individuals (25.25 ± 5.37 years old) both sexes, was selected. Chosen were perfusion, pressure, Perfusion measured feet by laser Doppler...

Significance: To explore brain architecture and pathology, a consistent reliable methodology to visualize the three-dimensional cerebral microvasculature is beneficial. Perfusion-based vascular labeling quick easily deliverable. However, quality of can vary with perfusion-based labels due aggregate formation, leakage, rapid photobleaching, incomplete perfusion. Aim: We describe simple, two-day ...
