Objective: The goal of this study was to explore the application effect of preoperative computed tomography (CT) angiography and color ultrasound-assisted design of lower limb perforator flaps in the repair of lower limb soft tissue defects. Repair of soft tissue defects in the lower limbs is a challenging surgical task, and accurate preoperative location of vascular structures and detailed design of the surgical plan are crucial to the success of the surgery. This study aims to improve the accuracy and effectiveness of lower limb perforator flap repair surgery by introducing CT angiography and color ultrasound technology.

The aim of this study was to compare the capability of different dual time (interval 1, 2, 3, or 4 hours) 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) with forced diuresis to diagnose prostate cancer (PCa). A retrospective review of 273 male patients from March 2009 to June 2019, with any focal 18F-FDG uptake in the prostate gland during PET/CT imaging. Early PET/CT imaging was performed 60 minutes after FDG injection.

Purpose: Altered brain functional connectivity has been reported in patients with amblyopia by recent neuroimaging studies. However, relatively little is known about the alterations in interhemispheric functional connectivity in amblyopia. The present study aimed to investigate the functional connectivity patterns between homotopic regions across hemispheres in patients with anisometropic and strabismic amblyopia under resting state.

Purpose: To detect the altered spontaneous brain activity patterns in children and adults with anisometropic amblyopia using resting-state functional magnetic resonance imaging (rs-fMRI) technique combined with the amplitude of low-frequency fluctuation (ALFF) method.

Methods: Thirty-two monocular anisometropic amblyopia and 34 normal-sight controls were divided into child group and adult group. Rs-fMRI was performed in all participants and analysis of ALFF value within the whole brain was conducted in each subject.

The aim of this study was to investigate possible changes of cortical thickness in the visual cortex in primary open-angle glaucoma (POAG) of varying severity. Twenty normal controls (NC), 20 mild (MP) and 17 severe (SP) POAG patients were recruited and scanned using magnetic resonance imaging. Cortical thickness analyses with regions of interest (V1, V2, ventral V3, V4 and V5/MT+) were used to assess the cortical changes among the three groups.

The aim of this study was to investigate possible morphologic changes of the visual cortex in primary open-angle glaucoma (POAG) with varying severity. Twenty normal controls (NC), 19 mild (MP) and 17 severe (SP) POAG patients were recruited and scanned using magnetic resonance imaging. Multi-parameter morphologic analyses with regions of interest (V5/MT+, anterior and posterior subregions of V1 and V2) were used to assess the cortical changes among the three groups.

Objectives: To examine possible changes in cortical thickness and their relationship to retinal nerve fiber layer (RNFL) thickness in patients with primary open-angle glaucoma (POAG).

Materials And Methods: Thirty-six patients with POAG and 40 matched healthy controls were enrolled in this study. All subjects underwent a comprehensive ophthalmologic examination and a high resolution structural magnetic resonance scan.
