The altered functional modular organization in systemic lupus erythematosus: an independent component analysis study.

The aim of this study was to investigate the abnormities in functional connectivity (FC) within each modular network and between modular networks in patients with systemic lupus erythematosus (SLE). Twelve meaningful modular networks were identified via independent component analysis from 41 patients and 40 volunteers. Parametric tests were used to compare the intra- and intermodular FC between the groups.

Differentiating Benign from Malignant Renal Tumors Using T2- and Diffusion-Weighted Images: A Comparison of Deep Learning and Radiomics Models Versus Assessment from Radiologists.

Background: Differentiating benign from malignant renal tumors is important for selection of the most effective treatment.

Purpose: To develop magnetic resonance imaging (MRI)-based deep learning (DL) models for differentiation of benign and malignant renal tumors and to compare their discrimination performance with the performance of radiomics models and assessment by radiologists.

Study Type: Retrospective.

Differentiation between fat-poor angiomyolipoma and clear cell renal cell carcinoma: qualitative and quantitative analysis using arterial spin labeling MR imaging.

Purpose: To assess the diagnostic effectiveness of arterial spin labeling (ASL) MR imaging in differentiating fat-poor AML from clear cell renal cell carcinoma (ccRCC).

Methods: In this prospective study, 29 ccRCC patients and 9 fat-poor AML patients underwent routine anatomical MRI and ASL at 3T before surgery after signing written informed consent form. For each tumor, tumor blood flow (TBF) was measured in a region of interest (ROI) which was positioned to outline the edge of the target lesions on ASL perfusion maps.

Comparative study of intestinal tuberculosis and primary small intestinal lymphoma.

Aim: To characterize the clinical, radiological, endoscopic and pathological features of intestinal tuberculosis (ITB) and primary small intestinal lymphoma (PSIL).

Methods: This was a retrospective study from February 2005 to October 2012 of patients with a diagnosis of ITB (n = 41) or PSIL (n = 37). All patients with ITB or PSIL underwent computed tomography (CT) and pathological examination.

[Assessment of the diagnostic value of CT and X-ray enterography for small intestinal Crohn disease].

Objective: To investigate the value of CT and X-ray enterography in the diagnosis of small intestinal Crohn disease(CD).

Methods: Data of 39 CD cases confirmed by surgery and pathology who underwent CT and X-ray enterography were analyzed retrospectively. All the patients had complete CT data, 28 cases had X-ray intestinal barium meal data, and 18 had sinus tract enterography.

The multislice CT findings of renal carcinoma associated with XP11.2 translocation/TFE gene fusion and collecting duct carcinoma.

Background: Renal cell carcinoma associated with Xp11.2 translocation and TFE gene fusion (Xp11.2/TFE RCC), and collecting duct carcinoma (CDC) are uncommon subtypes of renal cell carcinomas.

[Differential diagnosis of intestinal tuberculosis and primary small intestinal lymphoma using endoscopy and computerized tomography].

Objective: To analyze the characteristics of intestinal tuberculosis(ITB) and primary small intestinal lymphoma(PSIL) in order to provide clue for the differential diagnosis.

Methods: Data of 24 cases of ITB and 23 cases of PSIL confirmed by surgery and pathology were retrospectively analyzed. The clinical features, endoscopic and CT scan were compared.

[Multi-slice computed tomography diagnosis of collecting duct carcinoma].

Objective: To explore the diagnostic features of collecting duct carcinoma (CDC).

Methods: A total of 7 CDC patients were retrospectively examined by multi-slice computed tomography (MSCT). The relevant diagnostic parameters were assessed.
