Introduction Computed Tomography scans are a very important tool for diagnosis and assessment of response to treatment in the practice of medicine. Ionizing radiation in medical imaging is undoubtedly one of the most powerful diagnostic tools in medicine. Yet, as with all medical interventions, there are potential risks in addition to the clear potential benefits. Materials and Methods Two refe...

background : limited studies are available on the calculation of radiation exposure and its associated risks for people in contact with patients who have been treated with permanent prostate brachytherapy. in this study the changes in the radiation exposure were calculated in different stages of the bladder fullness in prostate seed brachytherapy. methods :magnetic resonance images of three pat...

Background: During interventional cardiology processes, patients especially women and children receive high radiation doses due to their sensitivity.Objective: In this study, we evaluated a pediatric patient dose separately in those undergone intervention cardiac procedure. Material and Methods: In this cross sectional study, a public hospital with 252 patients, Entrance Skin Dose (...

  Introduction: Radioactive materials deliver internal radiation dose to patients in nuclear medicine. Manual internal radiation dose assessment is a complicated method. Introduction of a simple dose calculation software is the main goal of the present study. Methods: Using the best current data in internal dose calculation (S-Factors) recommended by ICRP and by cons...

Background and Objectives: The expanding field of psychopharmacology is constantly seeking new and improved drugs to treat psychiatric disorders. Although psychotropic drugs have had a remarkable impact in psychiatry, their utilization, effectiveness, and side effects in the in clinical practice need continuous study. The present study was thus designed to analyze the pattern of psychotropic dr...

abstract background: in vivo measurements of applied dose during radiotherapy treatment, is important to ensure accurate dose delivery to patients. uncertainty in dose delivery should fall within ±5% of the prescribed dose as recommended by icru. assessment of dose for radiotherapy applications performed with various types of detectors. in this study, semiconductor diodes were used which have s...
