Impairments of large-scale functional networks in attention-deficit/hyperactivity disorder: a meta-analysis of resting-state functional connectivity.

Altered resting-state functional connectivity (rsFC) has been noted in large-scale functional networks in attention-deficit/hyperactivity disorder (ADHD). However, identifying consistent abnormalities of functional networks is difficult due to varied methods and results across studies. To integrate rsFC alterations and search for coherent patterns of intrinsic functional network impairments in ADHD, this research conducts a coordinate-based meta-analysis of voxel-wise seed-based rsFC studies comparing rsFC between ADHD patients and healthy controls.

Clinically enlarged lateral pelvic lymph nodes do not influence prognosis after neoadjuvant therapy and TME in stage III rectal cancer.

Purpose: The significance of lateral pelvic lymph nodes (LPLN) in rectal cancer remains unclear. The purpose of this study was to determine the outcome of patients with LPLNs identified on pretherapy imaging who were treated with neoadjuvant therapy followed by proctectomy without LPLN dissection.

Methods: Pretherapy imaging of patients with stage III rectal cancer was reviewed to determine perirectal and LPLN enlargement.

[Imaging technique and clinical application of 16-slice spiral CT for coronary artery].

This study was conducted in pursuit of the optimal imaging technique and for a primary clinical application of 16-slice multislice spiral computed tomography (MSCT) for coronary artery. Unenhanced and contrast-enhanced 16-slice SCT imaging was performed in 38 cases with retrospective electrocardiographic gating. MPR, MIP and VRT reconstruction of enhanced scan images were made in all cases, and CPR, VE reconstruction images were made in some cases.
