Effects of hyperoxia on resting state functional magnetic resonance imaging.

We studied the effect of oxygen inhalation during resting state functional MRI scanning in healthy control individuals. We hypothesized that resting state networks would be modified under hyperoxic conditions. Thirty-four normal volunteers were recruited for this study.

[Application of apparent diffusion coefficient ratio in the diagnosis of bladder cancer grading pre-operation].

Objective: To explore the value of apparent diffusion coefficient (ADC) ratio in the diagnosis of bladder cancer pre-operation by analyzing its differences among different grades of bladder cancer.

Methods: A total of 52 cases of bladder cancer were all definitely diagnosed with histological results.Routine examinations of magnetic resonance imaging (MRI) and diffusion-weighted imaging (DWI) were performed preoperatively on each patient.

Dual-energy computed tomography angiography for evaluating the renal vascular variants.

Background: Recognizing renal vascular variants preoperatively is important in order to avoid vascular complications during surgery. This study aimed to investigate the renal vascular variants with dual-energy computed tomography (DECT) angiography to provide valuable information for surgery.

Methods: A total of 378 patients underwent DECT.

Quantitative measures of comb sign in Crohn's disease: correlation with disease activity and laboratory indications.

To determine retrospectively if quantitative measures of the comb sign at CT enterography correlated with laboratory indications in Crohn's disease. We retrospectively included 72 known CD patients (47 male and 25 female patients) and 41 normal controls who had undergone CT enterography (CTE) from 2008 to 2010 and had high-sensitive C reaction protein (Hs-CRP) and erythrocyte sedimentation rate (ESR) results. We divided the 72 CD patients into two groups based on disease activity which was determined by Rutgeerts' score.

The effects of hypertension and body mass index on diffusion tensor imaging in schizophrenia.

Recently, the negative effects of hypertension and elevated body mass index on cognitive functioning in schizophrenia have been reported (Friedman et al., 2010). Data suggests that cognitive changes in hypertensive patients from the general population may be mediated, in part, by white matter damage.

Imaging features of small intestinal amyloidosis: a case report.

Amyloidosis is a rare disease characterized by forming pathological protein deposits in organs or tissues. The localized form of amyloidosis affecting small intestine is rare. We report a case of small intestine amyloidosis which presented gastrointestinal bleeding and abdominal pain.

Crohn's disease: CT enterography manifestations before and after treatment.

Purpose: The purpose of this study was to determine whether CT enterography (CTE) changes of Crohn's disease (CD) after treatment correlated with clinical remission.

Materials And Methods: We retrospectively studied 50 known CD patients (male: 35; female: 15) with clinical remission in a period of 3 years (2005-2008). CD was diagnosed by clinical, enteroscopic and pathologic manifestations.

Early-phase endotoxic shock-induced myocardial injury increases iNOS and selectin expression in macaque primate.

Background: Our previous study has established a macaque model with early-phase endotoxic shock. The present study further investigated myocardial and blood vessel injury in Macaques by examining the subsequent expression of ACP, selectins, iNOS, and cTnI in response to LPS treatment.

Methods: In an experiment with anaesthetised, instrumental macaques, eleven animals were randomised into: an En group (n=6), receiving a dose of 2.
