Comparative StudyVariabilities of Magnetic Resonance Imaging-, Computed Tomography-, and Positron Emission Tomography-Computed Tomography-Based Tumor and Lymph Node Delineations for Lung Cancer Radiation Therapy Planning.
To investigate interobserver delineation variability for gross tumor volumes of primary lung tumors and associated pathologic lymph nodes using magnetic resonance imaging (MRI), and to compare the results with computed tomography (CT) alone- and positron emission tomography (PET)-CT-based delineations. ⋯ Although MRI-based contouring showed overall larger variability than PET-CT, contouring variability depended on the interface type and was not significantly different between modalities, despite the limited observer experience with MRI. Multimodality imaging and combining different imaging characteristics might be the best approach to define the tumor volume most accurately.

Domestic Job Shortage or Job Maldistribution? A Geographic Analysis of the Current Radiation Oncology Job Market.
To examine whether permanent radiation oncologist (RO) employment opportunities vary based on geography. ⋯ This study presents a quantitative analysis of the RO job market. We found a disproportionately small number of opportunities compared with graduates trained in the Northeast, as well as a significant regional imbalance of academic versus nonacademic jobs. Long-term monitoring is required to confirm these results.
