Techniques for and uncertainties of MRI-based reconstruction of titanium tandem and ring brachytherapy applicators.

Purpose: Eliminating patient computed tomography (CT) scans for tandem and ring (T&R) brachytherapy can reduce overall procedure time and eliminates imaging dose. However, reconstructing titanium applicators in magnetic resonance imaging (MRI) is challenging. We evaluated the uncertainty of different applicator reconstruction workflows in MR-guided brachytherapy, and assessed the clinical impact of reconstruction uncertainties.

Palliative Radiotherapy: Inpatients, Outpatients, and the Changing Role of Supportive Care in Radiation Oncology.

Palliative radiotherapy is an effective treatment in alleviating many symptoms of advanced cancer. Short courses of radiotherapy provide rapid symptom relief and minimize impact on patients. Patients referred for palliative radiotherapy have many concerns beyond radiotherapy; often, these concerns are not fully addressed in traditional radiotherapy clinics.
