BACKGROUND This study aimed to investigate whether diffusion-weighted imaging (DWI) could contribute to the discrimination between benign and malignant renal cancer. METHODS We searched the PubMed electronic database for eligible studies. STATA 12.0 software was used for statistical analysis. The SMD and 95% CI were calculated. RESULTS Decreased ADC(More)
Image segmentation plays an important role in imaging analysis. Based on the Mercer kernel, the fuzzy kernel c-means clustering algorithm (FKCM) is derived from the fuzzy c-means clustering algorithm (FCM).The FKCM algorithm that provides image clustering can improve accuracy significantly compared with classical fuzzy c-Means algorithms. In this paper,(More)
To evaluate the feasibility of enhanced T2 star-weighted angiography (ESWAN) in differentiating endometrial from non-endometrial cysts. Forty-nine patients with 60 histopathologically proven ovarian cystic lesions underwent pelvic MRI including T1-weighted imaging (T1WI), T2-weighted imaging (T2WI), liver acquisition with volume acceleration, and ESWAN.(More)
OBJECTIVE The purpose of this study was to evaluate computed tomography (CT) virtual non-contrast (VNC) spectral imaging for gastric carcinoma. MATERIALS AND METHODS Fifty-two patients with histologically proven gastric carcinomas underwent gemstone spectral imaging (GSI) including non-contrast and contrast-enhanced hepatic arterial, portal venous, and(More)
OBJECTIVE The objective was to qualitatively and quantitatively evaluate hepatic metastases using computed tomography (CT) virtual noncontrast (VNC) spectral imaging in a retrospective analysis. METHODS Forty hepatic metastases patients underwent CT scans including the conventional true noncontrast (TNC) and the tri-phasic contrast-enhanced dual energy(More)
The title chiral compound, C(13)H(14)N(2)O(4), was prepared by an intra-cyclization reaction of methyl (S)-1-(4-hydr-oxy-5-meth-oxy-2-nitro-benz-yl)-5-oxopyrrolidine-2-carboxyl-ate in the presence of ethanol and iron. The five-membered substituted pyrrole ring adopts an approximate envelope conformation, while the seven-membered substituted diazepine ring(More)
To determine the clinical value of apparent diffusion coefficient (ADC) measurement by diffusion weighted magnetic resonance imaging (DW-MRI) in differentiating renal tumors. Electronic databases were searched using combinations of keywords and free words relating to renal tumor, ADC and DW-MRI. Based on carefully selected inclusion and exclusion criteria,(More)
