a discrete mibi avid lung lesion was found in cinematic views of myocardial perfusion imaging (mpi) of a 59 year-old woman. interestingly, the abnormal uptake in the lung was detectable only in the rest phase images and not in the images acquired in the stress phase. mpi was performed for pre-operation cardiac risk assessment before correction surgery for spinal canal stenosis.  she had no past...

introduction: percutaneous transluminal coronary angioplasty (ptca) is an effective method for revascularizing of stenotic coronary vessels. lack of response to this treatment, either in symptomatic or asymptomatic patients, is usually due to incomplete revascularization, restenosis, and/or irreversibility of myocardial perfusion. introduction of a noninvasive method with high predictive value ...

conclusion osem3d may provide better image quality and higher contrast than other methods for small animal imaging with the new myocardial imaging agent, [18f] fptp. results the location and size of myocardial infarction on pet images correlated closely with that observed with ttc staining. among the four reconstruction methods, osem3d provided the best assessment of infarct size (r2 = 0.994, p...

dextrocardia is a cardiac positional anomaly in which the heart is located in the right hemithorax with its base-to-apex axis directed to the right and caudad. situs inversus is an autosomal recessive disorder that causes organs in the chest and abdomen to be positioned in a mirror image from their normal position. dextrocardia may occur in isolation or as part of situs inversus. similarly, sit...

introduction: left ventricular ejection fraction (lvef) is considered to be the single most important prognostic factor in patients with previous myocardial infarction. lvef is not improved in all patients after coronary artery bypass grafting (cabg). this study aimed to assess the possibility of prediction of lvef changes after cabg using myocardial perfusion gated signle photon emission compu...

introduction: differentiating between ischemic cardiomyopathy (icm) and idiopathic dilated cardiomyopathy (idcm) is important as coronary revascularization can improve prognosis in the ischemic subgroup. due to inherent problems of coronary angiography in patients with depressed ejection fraction (ef) introducing a noninvasive tool to diagnose those who will benefit from angiography seems to be...
