Diagnostic Utility of Diffusion-weighted Magnetic Resonance Imaging in Differentiating Small Solid Renal Tumors (≤ 4 cm) at 3.0T Magnetic Resonance Imaging.

Background: The aim of this study was to assess the performance of apparent diffusion coefficient (ADC) measurement obtained with diffusion-weighted magnetic resonance imaging (DW-MRI) to distinguish renal cell carcinomas (RCCs) from small benign solid renal tumors (≤ 4 cm).

Methods: In this cross-sectional study, 49 consecutive patients with histopathologically confirmed small solid renal tumors, and seven healthy volunteers were imaged using nonenhanced MRI and DW-MRI. The ADC map was calculated using the b values of 0, 50, 400, and 600 s/mm 2 and values compared via the Kruskal-Wallis and Mann-Whitney tests.

Diffusion-weighted imaging of the kidneys and its relationship with residual renal function in continuous ambulatory peritoneal dialysis patients.

Objective: The objective of our study was to prospectively evaluate renal diffusion as shown by diffusion-weighted imaging (DWI) and its relationship with the residual renal function (RRF) in continuous ambulatory peritoneal dialysis (CAPD) patients.

Subjects And Methods: Forty CAPD patients and 40 healthy volunteers were recruited, and all underwent conventional and fat-saturated echo-planar DWI with three b values (0, 300, 600 s/mm(2)). The renal parenchymal thickness and apparent diffusion coefficients (ADCs) were measured, and both were compared between the two groups.

Unicentric mesenteric Castleman's disease with littoral cell angioma, anemia, growth retardation and amenorrhea: A case report.

Castleman's disease (CD) is a rare lymphoproliferative disorder of unknown origin, and littoral cell angioma (LCA) is a rare vascular tumor of the spleen with an unknown etiology. The current study reports the case of a 28-year-old female who presented with anemia, growth retardation and amenorrhea. Physical examination revealed a mass in the mesentery, splenomegaly with multiple small nodules, hepatomegaly and an infantile uterus.

[The diagnostic value of conventional MRI in the differentiation of malignant tumor from benign lesion in prostatic peripheral zone].

Objective: To evaluate the diagnostic capabilities of conventional MRI (T1WI, T2WI and Gd-enhancement T1WI) for differentiating prostate cancer from benign prostatic disorders in prostatic peripheral zone (PZ).

Methods: Respectively analyze the characteristics of conventional MRI in 46 cases of prostate cancer and 25 cases of benign prostatic disorders (with 28 lesions). Six indexes were initially screened by Chi2-test, and receiver operating characteristic curves (ROC) of these indexes were depicted, then Bayes discriminator was applied to discriminate all the lesions according to the indexes with statistic meaning.

Spontaneous retroperitoneal hemorrhage after hemodialysis involving anticoagulant agents.

In this paper, we described the symptoms and treatment of a patient with diabetic nephropathy accompanied by spontaneous retroperitoneal hemorrhage after hemodialysis. An elderly female patient with diabetic nephropathy presented with severe pain, numbness, and an increasing swelling in the left hip and left thigh after six sessions of hemodialysis involving the use of an antiplatelet drug and an anticoagulant agent. Her hemoglobin decreased to 46 g/L.
