Radiation exposure from diagnostic nuclear medicine examinations in Golestan province
Introduction: The aim of present study was to estimate effective dose from most common procedures performed in nuclear medicine departments of Golestan province. Methods: Data of nuclear medicine procedures performed in 2 nuclear medicine departments in Golestan province were collected during 4 years. Effective dose, collective effective dose and effective dose per examination were calculated ...
متن کاملNew techniques in nuclear medicine for tumor detection [Persian]
Widespread studies on tumor diagnosis has led to the development of techniques with greater sensitivity and improved specificity for detection of occult and small subclinical tumors. Tumor imaging by radiolabeling of tumor-specific antibodies (Immunoscintigraphy) or tissue specific biochemical agents (Receptor imaging) and especially physiologic imaging with positron emitters (PET), have ...
متن کاملMonte Carlo Techniques in Diagnostic and Therapeutic Nuclear Medicine
The use of the Monte Carlo method to simulate radiation transport has become the most accurate means of predicting absorbed dose distributions and other quantities of interest in radiation treatments of cancer patients using either external or radionuclide radiotherapy. This trend has continued for the estimation of the absorbed dose in diagnostic procedures using radionuclides as well as the a...

Xenon-133 and xenon-127 were compared by performing ventilation studies with both radionuclides in 19 patients with a variety of lung diseases. Assessment of the counting rate over the chest, relative to the radioactivity in the lungs, permitted the evaluation of each isotope in terms of usable photons detected by a scintillation camera with a large field of view and ap propriate collimili ion....
متن کاملDiagnostic value of diuretic renography in the study of obstructive uropathy in nuclear medicine [Persian]
Introduction: Urinary obstructive disease is one of the most common disorders in urinary system. Dilatation which is detected by sonography, is a key finding in obstruction in most of the cases, also could be found following surgery, lithotripsy and vesico–urethral reflux. Radioistope diuretic washout renography is a useful method to differentiate mechanical and non...
