Optimization of Replanning Processes for Volumetric Modulated Arc Therapy Plans at Risk of QA Failure Predicted by a Machine Learning Model

Applied Sciences
Patient-specific quality assurance (PSQA) procedures ensure the safe delivery of volumetric modulated arc therapy (VMAT) plans. PSQA requires extensive time and resources and may cause treatment delays if replanning is needed due to failures.

Functional Connectivity to the Cerebellum and Resting‐State Networks Predict Earlier Improvement of Dystonia Following Globus Pallidus Internus‐Deep Brain Stimulation (GPi‐DBS)

Movement Disorders, EarlyView.
Early improvement of dystonia after globus pallidus internus‐deep brain stimulation (GPi‐DBS) is associated with stimulation of the globus pallidus externus‐subthalamic nucleus (GPe‐STN) fibers and the lenticular fasciculus. Functional connectivity to the cerebellar cortex and the limbic and default mode networks predict early improvement of symptoms ...

International Registry of NKX2‐1‐Related Disorders: Clinical, Genetic, and Imaging Perspectives

Movement Disorders, EarlyView.
Abstract Background NKX2‐1–related disorders result from heterozygous variants in NKX2‐1, a gene crucial for brain, lung, and thyroid development. Although movement disorders, hypothyroidism, and neonatal respiratory distress are recognized, the full phenotype and genotype–phenotype relationships remain incompletely defined.

Respiration-Induced Intraorgan Deformation of the Liver: Implications for Treatment Planning in Patients Treated With Fiducial Tracking. [PDF]

, 2017
Stereotactic body radiation therapy is a well-tolerated modality for the treatment of primary and metastatic liver lesions, and fiducials are often used as surrogates for tumor tracking during treatment. We evaluated respiratory-induced liver deformation
