: The study objective was to investigate the performance of a dedicated convolutional neural network (CNN) optimized for wrist cartilage segmentation from 2D MR images. CNN utilized a planar architecture and patch-based (PB) training approach that ensured optimal performance in the presence of a limited amount of training data. The CNN was trained and validated in 20 multi-slice MRI datasets acquired with two different coils in 11 subjects (healthy volunteers and patients). The validation includ...

The article presents the pilot functional neuroimaging study results of the treatment process by means neuro-electrostimulator SYMPATHOCOR-01 in patients with depressive disorder. The study involved three patients. The changes in the brain's default mode network (DMN) as a result of neuro-electrostimulation course are demonstrated. Along with clinical improvement (HDRS-21 and BDI-II scales), changes in DMN's performance from neuroimaging data are shown. An increase in the medial prefrontal corte...

The objective of this study is to develop, test and validate a fully automatic, deep learning-based segmentation method for the wrist joint cartilage in magnetic resonance images. The study was conducted in 8 healthy volunteers and 3 patients with wrist joint diseases. 3D MRI datasets (20 in total) were acquired at 1.5T using a VIBE sequence. Wrist cartilage was segmented on coronal slices by a clinician and the convolutional neural network (CNN) was trained, developed and tested using the corre...
