Background: Hysterosalpingography (HSG) is an indispensable tool for diagnosing infertility in females. The procedure exposes female reproductive organs to ionizing radiation as the genitals are irradiated during the process. Investigating patient absorbed dose during the procedures is essential for effective radiological protection of the patient. Objective: This study aims to investigat...
A child with aggressive and resistant Kawasaki disease with coronary aneurysm is described. Despite two doses of immune globulin and high dose of aspirin the patient was treated with the third dose of immune globulin. The patient apparently responded to normalization of symptoms and signs, with no more progression of coronary artery abnormalities.
Introduction: Nowadays, we are witnessing a progressive application of radiology techniques in various communities as well as in Iran. Medical radiological examinations are one of the important sources of public radiological dose. Entrance skin doses and effective doses for patients in diagnostic radiology examinations should be assessed for the imaging techniques optimization and patient&rsquo...
Background: The aim of the study was to estimate the radiation dose during emergency exposure to patients treated with iodine-131 during the isolation period. Materials and Methods: The dose rate from a sample of 192 patients administrated by three different radioactivity of 131I (3.7, 5.55 and 7.4 GBq) was measured, at 1 meter after 1, 24 and 48 hours post dose administration, at three d...
Contralateral breast dose from primary breast irradiation has been implicated in the risk of second breast malignancies. In the radiotherapy departments of Iran, based on oncologist’s and physicist’s viewpoint, a special technique and set-up may be used for treatment of chest wall in mastectomized patient. The present study compared three different breast treatment techniques and set-up use...
Introduction: As a valuable imaging modality, Nuclear Medicine (NM) indications is raising in clinical practice. The remained portion administrated radioactive material in patients’ tissues is a critical issue, especially when the procedure is performed in hospitalized patients, where the non-radiation workers present. The aim of this study was evaluation the dose of non-radia...
Background: CT is a diagnostic imaging modality giving higher patient dose in comparison with other radiological procedures, so the calculation of organ dose in CT exams is very important. While methods to calculate the effective dose have been established (ICRP 26 and ICRP 60), they depend heavily on the ability to estimate the dose to radiosensitive organs from the CT procedure. However, dete...
