Histogram analysis of apparent diffusion coefficient maps in the prognosis of patients with locally advanced head and neck squamous cell carcinoma: Comparison of different region of interest selection methods.

Objective: To investigate the influence of different region of interest (ROI) selection methods on the histogram analysis of apparent diffusion coefficient (ADC) maps and to compare their performance in predicting overall survival (OS) in patients with locally advanced head and neck squamous cell carcinoma (HNSCC).

Methods: A total of 73 patients with locally advanced HNSCC who underwent pretreatment diffusion-weighted magnetic resonance imaging were included. Based on the largest slice ROI (ROI) and whole tumor ROI (ROI), ADC histogram parameters including mean ADC (ADC); median ADC (ADC); 10th, 25th, 75th, and 90th percentiles of ADC values (ADC, ADC, ADC, and ADC); kurtosis; and skewness were obtained.

Radiologic features of primary intracranial ectopic germinomas: Case reports and literature review.

Rationale: Germinomas are sensitive to radiation therapy and chemotherapy; therefore, correct imaging diagnosis is crucial for them. However, the imaging findings of germinomas originating from off-midline regions displayed different patterns from those originating from midline areas.

Patient Concerns: The objective of this study is to describe the radiologic features of primary ectopic germinoma.

Increased interhemispheric functional connectivity in college students with non-clinical depressive symptoms in resting state.

The underlying neural basis of non-clinical depressive symptoms (nCDSs) remains unclear. Interhemispheric functional connectivity has been suggested as one of the most robust characteristics of brain's intrinsic functional architecture. Here, we investigated the functional connectivity between homotopic points in the brain using the voxel-mirrored homotopic connectivity (VMHC) approach.
