Objective: we aimed to estimate the rate of MIBI washout of myocardium in patients with clinical ischemia as compared to the degree of reversibility between stress and rest studies. Patients and methods: this prospective study included 50 patients [34 males (60%) & 16 females (40 %)] with mean age 55.3 ± 10.1 years. All patients underwent ECG-gated SPECT Tc-99m MIBI myocardial perfusion imaging. Two days protocol (rest/stress) was used, the rest study was performed at 90 min and delayed images at 4 hours post-injection. While in stress phase images were performed after 30 min. The polar map of perfusion images acquired at stress and rest images at 90 min to detect reversibility. Also, polar map of 90 min was compared with delayed perfusion images at 4 h to calculate washout rate. Results: there was higher WR in the ischemic myocardial region of LAD (21.18±7.2) compared to the normal one (9.96±2.49), (p < 0.001). Also, in the region of RCA WR was 19.17±3.86 in ischemic wall versus 9.59±1.69 in normal walls (p<0.02) and (LCX) WR was 17.02 ± 2.6 in ischemic wall versus 9.63 ± 1.76 in normal walls (p<0.04). Additionally, the linear correlation of regional WR of each vascular territory was compared with the corresponding degree of reversibility with statistically significant for LAD (0.77), LCx (0.86) and RCA (0.64). Conclusion: There is higher WR of MIBI in ischemic walls in all vascular territories with significant correlation with its degree of reversibility that may potentiate the results of stress study.
Introduction:Malignant pleural mesothelioma (MPM) is an uncommon aggressive tumor arising from mesothelial cell lining the pleura. Loco regional progression remains the major cause of death. Aim of the study: To review the clinical role of 18 F-FDG
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
