In this work, we investigated whether APT-weighted CEST imaging can provide reproducible measurements across scan sessions and scanners. Within-session, between-session and between scanner reproducibility was calculated for 19 healthy volunteers and 7 patients with a brain tumor on two 3T MRI scanners...
76 young healthy volunteers (45 men and 31 women) underwent a 1.5T MR scan and 53 of them completed a comprehensive cognitive battery. Overall no gross significant differences between sexes were found in cortical thickness, surface area and curvature indexes. However, there was a significant ...

In total, 155 features were extracted per brain scan. The ADNI dataset was divided into a training set with 662 samples and a validation set with 74 samples, representing approximately 90% and 10% of the original cohort, respectively. This division approximately preserved the relative distributions...

It has been demonstrated by single photon emission computed tomography (SPECT) and positron emission tomography (PET) that frontal brain regions are stimulated during performance of the Wisconsin Card Sorting Test (WCST). The WCST is also regarded as one of the standard tests for the assessment of...
Purpose: To measure whole brain perfusion and to calculate CBF. Notes: (1) the labeling plane was placed 20 mm inferior to the lower edge of the imaging volume; (2) cover the cerebellum; (3) keep eyes open, not to think of anything in particular, and remain still during the scan. ...

The neuronavigation sensors were then registered to their MRI scan using fiducial points. On the first TMS visit, subjects’ motor threshold was obtained using the parameter estimation by sequential testing (PEST) procedure [31]. During each TMS session, subjects completed a single run of the ...
