congenital left ventricular diverticulum is a rare cardiac malformation. two categories of congenital ventricular diverticulum have been identified with regard to their localization: apical and non-apical. apical diverticula are always associated with midline thoraco-abdominal defects and other heart malformations. non-apical diverticula are always isolated defects. diagnosis is established by ...

UNLABELLED As a PET biomarker for inflammation, translocator protein (18 kDa) (TSPO) can be measured with an (18)F-labeled aryloxyanilide, (18)F-N-fluoroacetyl-N-(2,5-dimethoxybenzyl)-2-phenoxyaniline ((18)F-PBR06), in the human brain. The objective of this study was to estimate the radiation absorbed doses of (18)F-PBR06 based on biodistribution data in humans. METHODS After the injection of...

UNLABELLED 18F-labeled 2 beta-carbomethoxy-3beta-(4-chlorophenyl)-8-(-2-fluoroethyl)nortropane ([18F]FECNT) is a recently developed dopamine transporter ligand with potential applications in patients with Parkinson's disease and cocaine addiction. METHODS Estimates of the effective dose equivalent and doses for specific organs were made using biodistribution data from 16 Sprague-Dawley rats a...

We modified the Imaging Performance Assessment of CT scanners (ImPACT) to evaluate the organ doses and the effective dose based on the International Commission on Radiological Protection (ICRP) Publication 110 reference male/female phantom with the Aquilion ONE ViSION Edition scanner. To select the new CT scanner, the measurement results of the CTDI100,c and CTDI100,p for the 160 (head) and the...

The proceedings of a MIRD-sponsored continuing medical education session entitled, “Kidney Dose–Response for Radionuclide Therapy,” held at the 50th Annual Meeting of the Society of Nuclear Medicine, in New Orleans in 2003, have been collected in this special section of Cancer Biotherapy & Radiopharmaceuticals. A few years ago, hematologic toxicity was the focus of concern in radionuclide thera...

background: cardiovascular diseases have the highest death rates in human society. coronary artery disease is among the most important of these diseases. no treatment of cardiovascular disease has as much impact on the quality of life of the patients as the heart surgery. the recovery from heart surgery is associated with symptoms of pain and psychological distress. in the early recovery period...

echinococcus infection typically affects liver and lungs while rarely occur through heart. cardiac hydatidosis can be fatal or lead to major complications if it is not treated. the majority of patients with cardiac hydatid cysts complain from cardiac problems as their first presentation. however, this article reports an unusual case suffers from an interventricular hydatid cyst presented by abd...

abstract background iron overload is the main transfusion related side effects in patients with transfusion dependent hemoglobinopathies. severe iron deposition in tissues leads to organ dysfunction. many organs can be affected such as heart, liver, and endocrine organs. cardiac failure and liver fibrosis are the consequent of iron overload in transfusion dependent hemoglobinopathy. magnetic re...

conclusions: left ventricular systolic heart failure, may result in inter and intra-atrial asynchrony even in clinically stable patients without significant pulmonary hypertension and diastolic dysfunction. results: in heart failure patients either inter or intra-atrial asynchrony were far more common in comparison with normal subjects (p=0.008 and p=0.007 respectively). patients and methods: t...
