Accurate knowledge of ionizing radiation dose from cone-beam CT (CBCT) imaging in radiotherapy is important to allow concomitant risks to be estimated and for justification of imaging exposures. This study uses a Monte Carlo CBCT model to calculate imaging dose for a wide range of imaging protocols for male and female patients. The Elekta XVI CBCT system was modeled using GATE and simulated dos...

A case of ovarian sex cord tumor with annular tubules (SCTAT) in a 24-year old woman with Turner syndrome is presented. Close association of dysgenetic gonads and gonadoblastoma has been clearly documented, and there have been sporadic reports of patients with other gonadal tumors. To our knowledge, a case of SCTAT in a patient with 45,X/46,XX Turner syndrome has not been reported. On the basis...

in this study, the effect of chamomile extract on the ability of neonatal calves to absorb immunoglobulin g (igg) was evaluated. an ethanolic extract of chamomile was obtained with the concentration of 111 mg/ml. calves were randomly divided into four groups, each receiving one of four chamomile treatments; 1: low dose (lc; 5.5 mg/kg body weight; 2: moderate dose (mc; 11 mg/kg); 3: high dose (h...

background: the implementation of patient education within a hospital is a difficult task that plays a key role in improving and controlling diseases and providing quality healthcare services. objective: the current study evaluated the effect of patient education on the quality of nursing care and inpatient satisfaction in surgical wards of selected hospitals in isfahan, iran. methods: this qua...

A 72-year-old female patient underwent successful deployment of a single 3.0 18 mm Absorb bioresorbable vascular scaffold (Abbott Vascular, Santa Clara, California) to the mid right coronary artery (Figures 1A and 1B). The scaffolded segment was imaged simultaneously with coronary angiography and with the C7 Dragonfly (LightLab Imaging Inc., St. Jude Medical, Westford, Massachusetts) optical co...

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 differ...

Introduction: Interventional angiography procedures are increasingly used today. These techniques require a long time of standing near the patient and x-ray tube which lead to increase the radiation-dose of the staff and interventionists. This may also, in turn, lead to the occurrence of radiation deterministic effects. Since a large number of interventional radiology were perf...
