BACKGROUND The aim of this study was to analyze the influence of volumetric changes of bladder and rectum filling on the 3D dose distribution in prostate cancer radiotherapy. METHODS A total of 314 cone-beam CT (CBCT) image data sets from 19 patients were enrolled in this study. For each CBCT, the bladder and rectum were contoured and volume sizes were normalized to those on their original CT...

Introduction: Accurate evaluation of femoral and tibial torsion is essential for children or adult with legs deformity, becuse incorrect legs morphogenesis can lead to pathological situation. CT scan is commonly used for the measurement of skeletal bone parameters. But, disability in imaging from standing and sitting posture and absorb dose of patients are deficits of this meth...

objective: we report a case of intraperitoneal urinary bladder rupture i week following normal delivery in a primigravida, who presented with huge urinary ascites, anuria and renal failure. abdominal paracentesis and exploratory laparotomy was done and a diagnosis of intraperitoneal bladder rupture was made. the rent was repaired in layers. this may be preventable if adequate precaution in the ...

The purpose is to compare CT-based dosimetry with International Commission on Radiation Units and Measurements (ICRU 38) bladder and rectum reference points in patients of carcinoma of uterine cervix treated with intracavitary brachytherapy (ICA). Twenty-two consecutive patients were evaluated. Orthogonal radiographs and CT images were acquired and transferred to PLATO planning system. Bladder ...

bladder calculi, a rare condition in the pediatric population, occur most commonly as a result of either migration from the kidney or urinary stasis in the bladder. we report the case of a 3-year-old boy with recurrent urinary tract infections (uti) secondary to bladder calculi formation on the sutures from a previous herniorrhaphy.a 3-year-old boy with previous history of herniorrhaphy present...

introduction: the purpose of this study was to compare estimation of radiation absorbed doses to patients following bone scans with technetium-99m-labeled methylene diphosphonate (mdp) with the estimates given in mirdose software. methods: in this study, each patient was injected 25 mci of 99m tc-mdp. whole-body images from thirty patients were acquired by gamma camera at 10, 60, 90, 180 minute...

Introduction: In brachytherapy, as in external radiotherapy, image-guidance plays an important role. For GYN treatments it is standard to acquire at least CT images and preferably MR images prior to each treatment and to calculate the dose of the day on each set of images. Then, the dose to the target and to the organs at risk (OAR) is calculated with worst case scenario from I...

Background:Spontaneous bladder rupture is a rare condition, and almost all the reported cases in the world have been preceded by bladder dysfunction, radiotherapy, urinary tract obstruction, pelvic surgery, inflammation, and malignancy. Case report: In this study, we present the case of a 39-year-old woman (G: 4, P: 1, Ab: 2) who was in week 38 of pregnancy and attended our hospital with the on...
