Altered effective connectivity within the cingulo-frontal-parietal cognitive attention networks in chronic low back pain: a dynamic causal modeling study.

Dysfunction of the cingulo-frontal-parietal (CFP) cognitive attention network has been associated with the pathophysiology of chronic low back pain (cLBP). However, the direction of information processing within this network remains largely unknown. We aimed to study the effective connectivity among the CFP regions in 36 cLBP patients and 36 healthy controls by dynamic causal modeling (DCM).

Altered Amygdala-prefrontal Connectivity in Chronic Nonspecific Low Back Pain: Resting-state fMRI and Dynamic Causal Modelling Study.

Chronic nonspecific low back pain (cNLBP) is a leading contributor to disease burden worldwide that is difficult to treat due to its nonspecific aetiology and complexity. The amygdala is a complex of structurally and functionally heterogeneous nuclei that serve as a key neural substrate for the interactions between pain and negative affective states. However, whether the functions of amygdalar subcomponents are differentially altered in cNLBP remains unknown.

The utility of measuring the apparent diffusion coefficient for peritumoral zone in assessing infiltration depth of endometrial cancer.

Background: The invasion depth of endometrial cancer is one of the most important prognosis factors. The aim of the current study was to investigate the diagnostic value of the apparent diffusion coefficient (ADC) of the peritumoral zone for assessing the infiltration depth of endometrial cancer.

Methods: An institutional review board approved this prospective study, and all study participants provided informed consent.

Radiographic findings of hemolymphangioma in four patients: A case report.

Due to the rarity of hemolymphangioma, a limited number of cases of the disease have been reported in the literature thus far. The present case report describes the cases of 4 patients with hemolymphangioma that were diagnosed and treated at the Second Affiliated Hospital of Xi'an Jiaotong University (Xi'an, China). All patients were female, with a mean age of 44.

Significant MRI indicators of malignancy for breast non-mass enhancement.

Objective: To explore and evaluate new malignant predictors of breast non-mass enhancement lesions using the new BI-RADS MRI lexicon.

Methods: A dataset involving 422 consecutive women underwent breast 3.0 T MRI between January 2014 and July 2016 was assembled for this study.

[Brain gray matter abnormalities revealed by voxel-based morphometry in patients with chronic low back pain].

Objective: To explore the morphometric abnormalities of brain gray matter (GM) in patients with chronic low back pain (CLBP).

Methods: Thirty patients with CLBP and 30 healthy individuals were enrolled and examined with a 3.0 T magnetic resonance (MR) scanner.
