Abstract Purpose To investigate the utility of apparent diffusion coefficient (ADC) values for discriminating tumor in patients with prostate cancer from normal prostatic tissues healthy adult men, and to identify correlations between ADC histologic grade cancer. Materials Methods A total 125 male volunteers (mean age, 60 years; range, 50–86 years) 90 71 51–88 underwent diffusion‐weighted imaging (DWI) a single‐shot echo‐planar sequence using b‐factors 0 800 sec/mm 2 . was measured two...
To retrospectively evaluate the influence of postbiopsy hemorrhage on accuracy tumor detection at T2-weighted magnetic resonance (MR) imaging, dynamic contrast material-enhanced MR and diffusion-weighted (DW) imaging prostate cancer, with histologic findings as reference standard.The institutional review board approved this study waived requirement for informed consent. Forty male patients aged 62-84 years (mean age, 71 years) who had cancer underwent gland after ultrasonographically (US)...
Background Biparametric MRI (bpMRI) without dynamic contrast‐enhanced (DCE‐MRI) results in an elimination of adverse events, shortened examination time, and reduced costs, compared to multiparametric (mpMRI). The ability bpMRI detect clinically significant prostate cancer (csPC) with the Prostate Imaging Reporting Data System version 2.1 (PI‐RADS v2.1) standard mpMRI has not been studied extensively. Purpose To compare interobserver reliability diagnostic performance for detecting csPC using...
Abstract Purpose To evaluate the differences in enhancement of abdominal solid organ and major vessel on dynamic contrast‐enhanced magnetic resonance imaging (DCE‐MRI) obtained with gadolinium ethoxybenzyldiethylenetriamine pentaacetic acid (Gd‐EOB‐DTPA: EOB) diethylenetriamine (Gd‐DTPA) same patients. Materials Methods A total 13 healthy volunteers underwent repeat assessments MR examinations DCE‐MRI using either Gd‐DTPA at a dose 0.1 mmol/kg body weight or EOB 0.025 weight. DCE images were...

Purpose To compare standard diffusion-weighted (DW) imaging and diffusion kurtosis (DK) for prostate cancer (PC) detection characterization in a large patient cohort, with attention to the potential added value of DK imaging. Materials Methods This retrospective institutional review board-approved study received waiver informed consent. Two hundred eighty-five patients PC underwent 3.0-T phased-array coil magnetic resonance (MR) imaging, including sequence (b values 0, 500, 1000, 1500, 2000...
Objective The objective of our study was to investigate tumor conspicuity and the discrimination potential for aggressiveness on diffusion-weighted magnetic resonance imaging (DW-MRI) with high b value at 3-T. Materials Methods institutional review board approved this waived requirement informed consent. A total 50 patients prostate cancer (69 foci; 48 in PZ, 20 TZ, one whole prostate) who underwent multiparametric MRI including DW-MRI (b values: 0, 1000 s/mm2 2000 s/mm2) a 3-T system were...

To identify age-related changes and differences in the diffusion of water molecules within prostate, through diffusion-weighted imaging (DWI) prostate gland healthy adult Japanese men.A total 114 male volunteers (mean age, 55 years; range, 24-81 years) underwent DWI with a single-shot echo-planar (EPI) sequence using b-factors 0 1000 seconds/mm(2). Apparent coefficient (ADC) values six locations peripheral zone (PZ) two central (CG) were measured correlations between region age examined.ADC...
The aim of this retrospective study was to assess the enhancement patterns hepatic hemangiomas on gadoxetate disodium.A total 22 patients with 32 (23 typical type and nine high-flow type) in normal liver underwent disodium-enhanced MRI. Contrast-enhanced images were obtained before after contrast injection, including arterial phase, portal equilibrium three hepatobiliary phases (10, 15 20 minutes). Signal-to-phantom ratios vein as well lesion-to-liver contrast-to-phantom assessed.Mean...
In prostate MRI, single-shot EPI (ssEPI) DWI still suffers from distortion and blurring. Multi-shot (msEPI) overcomes the drawbacks of ssEPI DWI. The aim this article was to compare image quality diagnostic performance for clinically significant cancer (csPC) between msEPI This retrospective study included 134 patients with suspected PC who underwent 3.0 T MRI subsequent MRI-guided biopsy. Three radiologists independently assessed anatomical distortion, edge clarity, lesion conspicuity score...
