Magnetic Resonance Imaging of the Prostate
Prostate magnetic resonance (MR) provides high-resolution images of the prostate; seminal vesicles; and nearby pelvic organs and structures, including the bladder and rectum.
Diagnosis & Disease Information
NBI Detects More Bladder Ca Recurrences
Narrow-band imaging (NBI) cystoscopy improves detection of recurrent non-muscle-invasive bladder tumors over standard white-light imaging (WLI) cystoscopy, according to a report in BJU International (2008; published online ahead of print).
MRI-TRUS Feasible for Targeted Biopsies
WASHINGTON, D.C.—An imaging technique that combines MRI and transrectal ultrasound (MRI-TRUS) is feasible for performing targeted prostate biopsies. This approach may have some advantages over traditional biopsy methods, researchers said here at the Society of Interventional Radiology annual meeting.
Imaging Modality Could Improve PCNL
WASHINGTON, D.C.—An imaging modality called cone beam CT may improve intraprocedural management decisions during percutaneous nephrolithotripsy (PCNL), researchers say.
The Perils of ‘Nephron-Wasting’ Surgery
The broad application of cross-sectional imaging has led to the incidental discovery of small renal masses (SRM) as the most common presentation for localized kidney cancer.
TRUS Alone is Not Enough for Prostate Cancer Detection
Gray-scale transrectal ultrasonography (TRUS) alone has a limited potential to detect prostate cancer, particularly in patients with total PSA levels below 20 ng/mL, researchers reported in the Journal of Medical Imaging and Radiation Oncology (2008;52:24-28).
CT Fluoroscopy Okay for Nephrostomy
SEATTLE—When patients cannot be imaged with ultrasound, CT fluoroscopy can be used safely and effectively for percutaneous nephrostomy tube placement, British researchers reported here at the Society for Interventional Radiology annual meeting.
Dutasteride Improves PCa Detection
Prostate cancer detection can be improved by pretreating men with dutasteride prior to biopsy guided by contrast-enhanced color Doppler (CECD) imaging, according to researchers.
Gadolinium Imaging Dangers Reported
Use of gadolinium as a contrast agent during magnetic resonance imaging (MRI) or magnetic resonance angiography (MRA) may increase the risk of a condition called nephrogenic fibrosing dermopathy (NFD) by sevenfold.
