There are many ways to be exposed radiation in life. Medical applications, particular, the most important form of severe exposure. In medical Computed Tomography (CT) scans first place, while nuclear medicine is second place. Of course, dose absorbed by tissue and therefore organs directly proportional risks health. medicine, due radioisotopes placed body for therapeutic purposes, some doses no...

PURPOSE To evaluate the imaging appearance of the thymus in the myasthenic patients by using chemical shift magnetic resonance imaging, and, to correlate the chemical shift ratio (CSR) with pathologic findings after surgical excision. MATERIALS AND METHODS In the past year, a total of 11 myasthenic patients (4 males, 7 females; age range of 26-65 years), have been investigated by MRI centered...

In nuclear medicine, the dose received by critical organs becomes important due to radioisotopes placed inside body. Medical applications are among main causes of radiation exposure general population. these applications, Computed Tomography (CT) scans primary source, while medicine is second largest. The informed decisions that must be made regarding use procedures require a better understandi...

Medical science seems to be on the threshold of a revolution: It seems possible that in twenty years, doctors will be able to replace organs in the human body like parts in a car. This is thanks to the recent achievement of a team from the Medical Research Council Center for Regenerative Medicine in Edinburgh, Scotland - the group of researchers tried to regenerate the thymus gland in mice. The...

PURPOSE To prospectively evaluate chemical shift magnetic resonance (MR) imaging for differentiating thymic hyperplasia from tumors of the thymus gland. MATERIALS AND METHODS The institutional review board approved this study; informed consent was obtained and patient confidentiality was protected. The authors assessed 41 patients (17 male, 24 female; age range, 16-78 years) in whom thymic le...

Background & Objective: The thymus gland significantly affects fetal immune system maturation. Additionally, there is a linear association between size and its performance. Given the high prevalence of vitamin D deficiency in Iran scarce studies with conflicting results, subjecting maternal concentration effect on thymus, we decided to investigate relation mid-gestation. This study also aimed g...
