BACKGROUND To identify the value of unilateral pedal lymphangiography (LPG) plus computed tomography angiography (CTA) in accurate depiction of persistent idiopathic chyluria undetectable by ordinary contrast CT. METHODS Eighteen patients 44-63 years of age with persistent idiopathic chyluria who failed conservative management were included. Ordinary CT had not revealed a chyle leak. Cystosco...
White light endoscopy is widely used for diagnostic imaging of the interior of organs and body cavities, but the inability to correlate individual 2D images with 3D organ morphology limits its utility for quantitative or longitudinal studies of disease physiology or cancer surveillance. As a result, most endoscopy videos, which carry enormous data potential, are used only for real-time guidance...
Computed tomography (CT) based virtual cystoscopy (VC) has been studied as a potential tool for screening bladder cancer. It is accurate in localizing tumor of size larger than 1 cm and less expensive, as compared to fiberoptic cystoscopy. However, it is invasive and difficult to perform due to using Foley catheter for bladder insufflating with air. In a previous work, we investigated a magneti...
INTRODUCTION The present study was carried out to compare the efficacy of transabdominal ultrasonography and intravenous urography in the diagnosis of bladder carcinoma in those patients presenting painless hematuria. MATERIALS AND METHODS Medical records of 100 patients who had both ultrasonography and intravenous urography were studied. The reported findings of these investigations were cor...
We propose a new partial volume (PV) segmentation scheme to extract bladder wall for computer aided detection (CAD) of bladder lesions using multispectral MR images. Compared with CT images, MR images provide not only a better tissue contrast between bladder wall and bladder lumen, but also the multispectral information. As multispectral images are spatially registered over three-dimensional sp...
Cabral Ribeiro J, Leite C. BMJ Case Rep 2017. doi:10.1136/bcr-2017-219690 DESCRIPTION Vaginal pessaries represent a valid therapeutic option for the management of female pelvic organ prolapse in elderly women with significant comorbidities. Although leading to good functional and quality of life outcomes, when neglected, they can cause significant and severe complications. An 87-year-old woman ...
