discussion the reason is that we assess the relative and not absolute differences of the tracer uptake in this imaging modality. there may be other findings on mpi images which could help us overcome this pitfall, including detecting wall motion abnormalities, lung uptake of the tracer, or transient ischemic dilation. another important issue is the ecg changes during exercise stress testing, wh...

introduction: suspension of isolated hepatocyes is now being used in an increasing number of biochemical investigations, including drug metabolism and toxicity studies. isolated hepatocyes, retain many of the essential properties of the intact tissue including permeability charactreristics. material and methods: in this method at first liver is subjected to a nonrecirculating perfusion with cal...

Background: Cerebral hyperperfusion syndrome (CHS) is a failure of autoregulation after revascularization procedure. It has rarely been reported in patients with no pre-existing cerebral hypoperfusion. Case Report: We present rare case patient who underwent stent graft implantation to treat postirradiated carotid blowout syndrome. The developed hypertension, focal neurological deficit, and seiz...

The knowledge of myocardial perfusion in healthy volunteers is fundamental for evaluation of patients with ischemic heart disease. The study was conducted to determine range, regional variability, and transmural gradient of myocardial perfusion in normal volunteers with Magnetic Resonance Perfusion Imaging (MRPI). Perfusion was assessed in 17 healthy volunteers (age: 20-47 yr, 11 males) at rest...

OBJECTIVE Hepatic artery perfusion scintigraphy is a routine procedure for patient evaluation before Y-90 radiomicrosphere therapy and mostly used for prediction of extrahepatic leakage. Moreover, it also displays perfusion pattern of tumours, which is an important parameter on success of the therapy. The aim of this study is to assess the relation between the perfusion pattern on hepatic arter...

Left ventricular (LV) function and volumes, along with myocardial perfusion, have major diagnostic and prognostic importance inpatients with coronary artery disease [4,11,13,14, 18,20,27]. Myocardial perfusion scintigraphy is a well-established technique for evaluation of myocardial perfusion [16,26,37,38]. Electro cardiographic gating during the acquisition of SPECT perfusion images has become...

Abstract Purpose First, to determine image quality using different cardiovascular magnetic resonance (CMR) perfusion protocols in patients with all available active device types a real-world setting, including non-conditional devices. Second, demonstrate feasibility of high-quality imaging spoiled gradient echo (sGE) for non-invasive stress-testing. Methods From August 2020 March 2022, N=222 ca...

Objective: As the aqueous extract of Capparis spinosa (CS) possess antidiabetic effect, he present study aims to reveal the possible  mechanism of action of CS in diabetic mice.Materials and Methods: Both single and repeated oral administrations of aqueous extract of CS were performed in multi-low dose streptozotocin-induced (MLDS) diabetic mice. Euglycemic hyperinsulinemic clamp was used in as...
