background the present data show a global increase in the rate of cardiovascular disease. cardiac ct angiography has developed as a fast and non-invasive cardiac imaging modality following the introduction of multi-slice computed tomogaraphy. conclusions the total mean radiation dose to the thyroid and gonads was 0.36 msv, and 96.5 μsv, respectively for the subjects. these values were high for ...

background: in radiation therapy, peripheral dose or the dose outside the radiotherapy field, is important when anatomical structures with very low dose tolerances are involved. one of these critical organs in pelvic irradiation is testis. the amount of radiation delivered to the testes in radiotherapy must be kept as small as possible, consistent with the limit dose of this organ. the threshol...

BACKGROUND Medical X-rays are the largest man-made source of public exposure to ionizing radiation. While the benefits of Computed Tomography (CT) are well known in accurate diagnosis, those benefits are not risk-free. CT is a device with higher patient dose in comparison with other conventional radiation procedures. OBJECTIVE This study is aimed at evaluating radiation dose to patients from ...

Multidetector Computed Tomography (MDCT) technology plays an important role in the evaluation of injured patients. At our institution pelvic X-ray (PXR) is obtained routinely on trauma patients. Many also receive MDCT of the abdomen and pelvis for other indications. We hypothesized that there would be a substantial cost savings in adopting a policy of deferring PXR in a hemodynamically normal p...

The aim of this study was to determine whether the addition of concurrent cisplalin and hyperfractionation in external pelvic radiotherapy improves local control and survival in paticnts with locally advanced carcinoma cervix as compared to treatment with conventional radiolherap.J alonc. The morbidity oftwo treatment protocols was also compared. Sixty patients of ne" I) diagnosed squamous cell...

The influence of sex on bone mineral density (BMD) and the bone mineral content (BMC) have been analysed in selected bones of the thoracic and pelvic limbs of African ostriches. The examination was conducted with the use of a densitometer, using the technology of affinited beam of X-ray and the programme for animal research. It was shown that the analysed bones of ostrich skeleton differed sign...

background : to determine the role of letrozole, an aromatase inhibitor,in the treatment of endometriotic pain.   methods: in this prospective, randomized, controlled clinical trial in minimallyinvasive surgery research center,51 women with pelvic endometriosis and endometriotic pain (dyspareunia, dysmenorrhea, pelvic pain) score of 5 or more (for at least one of these endometriotic pain), afte...
