Background And Purpose: Precise and individualized targeting of the ventral intermediate thalamic nucleus for the MR-guided focused ultrasound is crucial for enhancing treatment efficacy and avoiding undesirable side effects. In this study, we tested the hypothesis that the spatial relationships between Thalamus Optimized Multi Atlas Segmentation derived segmentations and the post-focused ultrasound lesion can predict post-operative side effects in patients treated with MR-guided focused ultrasound.
Materials And Methods: We retrospectively analyzed 30 patients (essential tremor, n = 26; tremor-dominant Parkinson's disease, n = 4) who underwent unilateral ventral intermediate thalamic nucleus focused ultrasound treatment.
A radio-pathomic machine learning (ML) model has been developed to estimate tumor cell density, cytoplasm density (Cyt) and extracellular fluid density (ECF) from multimodal MR images and autopsy pathology. In this multicenter study, we implemented this model to test its ability to predict survival in patients with recurrent glioblastoma (rGBM) treated with chemotherapy. Pre- and post-contrast T-weighted, FLAIR and ADC images were used to generate radio-pathomic maps for 51 patients with longitudinal pre- and post-treatment scans.

Objective: The paper describes a shared care programme developed by mental health services and general practitioners for shifting patients with chronic psychiatric disorders to the care of a general practitioner. The programme is characterized by: (i) a dedicated mental health service general practitioner liaison position to manage the programme and provide support to both patients and doctors; (ii) a multidisciplinary care planning meeting that includes mental health staff, the patient, the general practitioner and a carer; and (iii) a jointly developed individual management plan that specifies patient issues, strategies to deal with these issues, persons responsible for monitoring and a review date.
Methods: The shared care protocol, the results of a review of patient mental health indicators and general practitioner satisfaction with the programme are described.
