Quantitative stress-redistribution sequential imaging optimises MPI with the lowest dose of radiation per patient

Use of the lowest necessary radiation dose.

Radiologists are taught that CT with low radiation doses is morally and ethically justified provided that this technique produces images adequate for diagnostic purposes. CT accounts for a large proportion of overall radiographic exposure to the patient population. In this issue of the AJNR, Lev and colleagues address an important, though often ignored, topic. They carried out a controlled stud...

Computed Tomography in Abdominal Imaging: How to Gain Maximum Diagnostic Information at the Lowest Radiation Dose

Assessment of Patient Dose with Special Look at Pediatrics during Cardiovascular Imaging

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 (...

Estimation of radiation dose of emergency exposure during the hospitalized 131I therapy patient

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...

Evaluating the Effect of Injected Dose of 99mTc- MIBI on the Quantitative Parameters of Myocardial Perfusion Imaging

Background: 99mTc-MIBI cardiac perfusion scanning is recognized as a clinically useful method in evaluating coronary artery disease. By the implementation of new imaging techniques and systems, it seems possible to obtain high-quality images with a lower dose of radiopharmaceuticals. The purpose of this study was to evaluate the effect of injection dose of 99mTc-MIBI on quantitative parameters ...
