•To compare magnetic resonance imaging (MRI)-targeted biopsies with extended systematic for the detection of significant prostate cancer.•In all, 555 consecutive patients suspicion cancer had pre-biopsy dynamic contrast-enhanced 1.5-tesla (T) MRI pelvic coil, 10-12 transrectal ultrasound-guided plus two targeted at any area suspicious malignancy. •Significant was defined as >5 mm total length and/or Gleason pattern >3. •Cancer and grade biopsy were reported located on a 24-sector map.•Median...

Purpose To compare biopsy performance of two approaches for multiparametric magnetic resonance (MR)-targeted (TB) with that extended systematic (SB) in prostate cancer (PCa) detection. Materials and Methods This institutional review board–approved multicenter prospective study (May 2009 to January 2011) included 95 patients informed consent who were suspected having PCa, a suspicious abnormality (target) at prebiopsy MR. Patients underwent 12-core SB four-core TB transrectal ultrasonographic...

We assessed the value of pelvic phased array dynamic contrast enhanced magnetic resonance imaging for predicting intraprostatic location and volume clinically localized prostate cancers.Suspicious areas on prospective pre-biopsy in 24 patients were assigned a malignancy score located with respect to anatomical features, gland side, transition peripheral zone boundaries. The largest surface area measured. These findings compared radical prostatectomy specimen histopathology...

To preoperatively assess the composition of urinary stones by using dual-energy computed tomography (CT), with postoperative in vitro x-ray diffraction analysis as reference standard.Institutional review board approval was obtained, and all participants provided written informed consent. Twenty-seven patients aged 50-64 years renal stones, who were scheduled for stone extraction percutaneous nephrolithotomy (PCNL), underwent nonenhanced single-source multidetector CT 2-mm section thickness,...

Abstract Background. Angiosarcomas account for <2% of all soft tissue sarcomas. This subtype is one the most aggressive forms sarcoma. The prognosis angiosarcoma patients in advanced phase remains poor with current cytotoxic agents (progression-free survival [PFS] time ∼4 months and overall [OS] ∼8 months). We investigated antitumor activity sorafenib metastatic or angiosarcomas a II trial. Methods. conducted stratified primary endpoint was progression-free rate (PFR) at 9 according...

Abstract BACKGROUND To describe the precise location of transition zone (TZ) and anterior fibromuscular stroma (AFMS) prostate cancers (TZ/AFMS) within histological zones at various stages development to demonstrate their pattern intraprostatic spread from site origin. METHODS Anterior TZ/AFMS excluding anterolateral part peripheral zone, were identified radical prostatectomy specimens. Morphometric histopathological study included largest surface area, volume spatial distribution. RESULTS...

To follow up the growth of renal angiomyolipomas (AMLs).Patients with known AML (n = 55) were divided into three groups on basis initial clinical and computed tomographic (CT) findings: group 1, isolated 43); 2, multiple AMLs without tuberous sclerosis (TS) 6); 3, TS 6). Follow-up ultrasonography (US) CT performed in 55 31 patients, respectively. Growth 59) was evaluated area follow-up images.Mean percentage 17%, 128%, 47%, mean rate per year 5%, 22%, 18% New lesions noted patients 1 but no...

We determined whether renal vein ostium wall invasion could be predicted by and inferior vena cava diameter on imaging. also it is a prognostic factor for recurrence survival after radical nephrectomy thrombus ablation cell carcinoma with an tumor thrombus.From January 2000 to 2006 was performed in 446 patients, of whom 32 (7.2%) underwent extraction complete resection the ostium. When necessary, partial circumferential done 5 8 respectively, as well replacement adhesions. The largest...

Abstract BACKGROUND To describe the precise location of peripheral zone (PZ) prostate cancers at various stages development and to demonstrate their pattern intraprostatic spread from site origin. METHODS PZ defined as located in including anterolateral part PZ, were identified radical prostatectomy specimens. morphometric histopathological study included largest surface area, volume spatial distribution. RESULTS Out 188 cancers, 179 <4 cm 3 168 <2 . still confined origin for volumes...
