A multi-scan MRI-based virtual cystoscopy
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...
متن کاملVirtual computed tomography cystoscopy in bladder pathologies.
OBJECTIVE Assessed the usefulness of virtual cystoscopy performed with multidetector computed tomography (CT) in patients with different urinary bladder pathologies compared to the conventional cystoscopy. MATERIALS AND METHODS Eighteen patients with different bladder pathologies, which consisted of 11 tumors, 3 diverticula, 2 trabecular changes and 2 stones, were assessed with conventional c...
متن کامل3D Elastography Using Freehand Ultrasound
We present an elastography system using freehand 3D ultrasound. A review is provided of the standard elastography methods that have been adapted for this purpose. The scanning protocol is simple and promising results are presented of 3D strain images from freehand scans. Robustness is a problem, however, and the main sources of error are explained. Measures have been developed to improve the qu...
متن کاملComparison of virtual cystoscopy and transabdominal ultrasonography with conventional cystoscopy for bladder tumor detection.
PURPOSE We compare virtual cystoscopy (VC) and transabdominal ultrasonography (US) with conventional cystoscopy (CC),the gold standard, for detection of bladder tumors. PATIENTS AND METHODS Forty-five patients suspected to have bladder neoplasms were evaluated prospectively.They underwent transabdominal US, followed by VC and CC. We compared sensitivity and specificity of US and VC and their ...
متن کاملVirtual cystoscopy: reality in imaging of bladder tuberculosis.
We present a case of urinary tuberculosis investigated initially by ultrasound and multidetector computed tomography (MDCT). The MDCT-derived volumetric data were used to generate virtual cystoscopy (VC) images, which revealed a bladder ulcer. The presence of this ulcer was confirmed by conventional cystoscopy-guided biopsy and there was good agreement regarding various features of the ulcer, s...
