PURPOSE To evaluate the non-Gaussian water diffusion properties of prostate cancer (PCa) and determine the diagnostic performance of diffusion kurtosis (DK) imaging for distinguishing PCa from benign tissues within the peripheral zone (PZ), and assessing tumor lesions with different Gleason scores. MATERIALS AND METHODS Nineteen patients who underwent(More)
OBJECTIVE Antegrade ipsilateral subintimal angioplasty for recanalization of the superficial femoral arteries (SFAs) has a failure rate of 10%-20%. We report our initial experiences performing recanalization of the SFA or popliteal artery (PA) in cases of failed antegrade angioplasty using a medial infracondylar retrograde popliteal approach with the(More)
OBJECTIVE The objective of this study was to investigate the non-Gaussian water diffusion properties in bladder cancer and assess the efficacy of diffusion kurtosis imaging for estimating the histological grade of bladder cancer. METHODS Twenty-one patients with bladder cancer (high-grade, 12; low-grade, 9) and 17 negative controls who underwent(More)
The aim of this study was to evaluate the role of diffusion kurtosis imaging (DKI) in the characterization of clear cell renal cell carcinoma (ccRCC) and to correlate DKI parameters with tumor cellularity. Fifty-nine patients with pathologically diagnosed ccRCCs were evaluated by DKI on a 3-T scanner. Regions of interest were drawn on the maps of the mean(More)
PURPOSE To study the quantitative T2* mapping for thyroid nodules and to explore the use of T2* values to differentiate papillary thyroid carcinoma (PTC) from benign thyroid nodules, with histopathological examination as a reference standard. MATERIALS AND METHODS Twenty-eight consecutive patients with thyroid nodules were subjected to a 3.0T magnetic(More)
This study aimed to evaluate the application value of diffusion-weighted imaging (DWI) for assessing paradoxical puborectalis syndrome (PPS) in patients with obstructive defecation syndrome (ODS). The medical records of 72 ODS patients who underwent magnetic resonance (MR)-DWI and MR-defecography were retrospectively reviewed. The differences in the(More)
