BACKGROUND In postmenopausal women, the presence of risk factors for coronary artery disease (CAD) increases. However, the difference in prevalence of ischemia between pre- and postmenopausal women with multiple risk factors for CAD has not been well established. OBJECTIVES To compare the prevalence of ischemia on Tc99m-sestamibi myocardial perfusion scintigraphy (MPS) in pre- and postmenopau...
Quantitative SPECT as well as simultaneous acquisition of multiple isotopes with SPECT in the clinical field, although clinically interesting, are still limited by reconstruction artifacts and computing power. As a considerable step in this direction, we have implemented an efficient reconstructor with variance reduced Monte-Carlo-simulation in the forward and/or backward projection of an OS-EM...
OBJECTIVE It has been reported that both obsessive-compulsive disorder (OCD) and attention deficit hyperactivity disorder (ADHD) might be related to impairments in frontal-striatal brain circuits. Besides, these two disorders are frequently comorbid. However, there are no published studies directly comparing the neurobiological findings in these two disorders. The objective of the study was to ...
مقدمه. در پی وقوع رادیوتروریسم یا حوادث هسته‌ای-رادیولوژیک آزاد شدن ید 131 می‌تواند پس از ایجاد آلودگی داخلی منجر به آسیب غدد بزاقی شود. سنتی‌گرافی غدد بزاقی با تکنسیوم m99 روشی آسان و مطمئن برای تعیین شاخص‌های کمی عملکرد غدد بزاقی است که به وسیله آن می‌توان میزان آسیب دیدگی را نشان داد. احتمال وقوع این اتفاقات در میان نیروهای شاغل (بین18 تا 50 سال) بیش از دیگران است. هدف این مطالعه استخرا...
CD133 mesenchymal cells were enriched using magnetic microbead anti-CD133 antibody from bone marrow mononuclear cells (BMMNCs). Flow cytometry and immunocytochemistry analysis using specific antibodies revealed that these cells were essentially 89 ± 4% CD133(+) and 8 ± 5% CD34(+). CD133(+)/CD34(+) BMMNCs secrete important bioactive proteins such as cardiotrophin-1, angiogenic and neurogenic fac...
Oesophageal transit and gastric emptying of liquids and solids was measured in eight normal subjects with a single test meal containing In113 labelled water and an omelette labelled with Tc99m sulphur colloid. Each volunteer was studied, basally, whilst continuously smoking, and while chewing nicotine gum. Neither liquid, nor solid oesophageal transit were affected by smoking, or gum. Liquid ga...
Within the evaluation process of living kidney donors, split renal function is usually evaluated by renal scintigraphy. Since split renal function measured by conventional posterior scans depends on the position of the kidney, actual suitable donors may be rejected because of an inaccurate examination technique. We report the case of a 28-year-old male living kidney donor. Due to a complex vasc...
DESCRIPTION A 54-year-old patient underwent right radical nephrectomy for what was then diagnosed as a Stage-II (T2bN0M0) renal cell carcinoma (RCC). Four months after surgery, the patient reported of pelvic pain and had a rising serum alkaline-phosphatase level. The tecnetium-99 mmethylene-diphosphate (Tc99m-MDP) bone scan then demonstrated a focus of uptake in the right ischium, corresponding...
