Absence of an anticipated racial disparity in interval breast cancer within a large health care organization.
The researchers sought to estimate the extent of an anticipated racial disparity in interval breast cancer (IBC) within a single, large health care organization. Contrary to expectation, in patient-adjusted models, there was no IBC racial disparity. The sorting of patients by race across facilities appears to have mitigated an otherwise anticipated disparity in IBC.

Adaptive anatomical preservation optimal denoising for radiation therapy daily MRI.
An innovative method, adaptive anatomical preservation optimal denoising (AAPOD), was developed for optimal image denoising, i.e., to maximally reduce noise while preserving the tissue boundaries. The experimental results demonstrated that AAPOD was capable of reducing noise adaptively and optimally while avoiding tissue boundary losses.

Multi-institutional randomized trial testing the utility of an interactive three-dimensional contouring atlas among radiation oncology residents.
The present study reports on the efficacy and usability of a web-based contouring atlas compared with those of existing contouring resources in a randomized trial. Compared with the residents using currently available resources, the residents using eContour had improved contour agreement with both the consensus and the expert contours for the high-risk clinical target volume and greater agreement with the expert contour for the contralateral parotid gland.

Development of a fast Monte Carlo dose calculation system for online adaptive radiation therapy quality assurance.
This article describes the development of a fast Monte Carlo dose calculating system for validating online magnetic resonance imaging radiation therapy adaptive plans with both speed and accuracy. The Monte Carlo system is based on a simplified dose planning method code that incorporates a vendor-provided head model. A validated Monte Carlo code (gPENELOPE) was used to benchmark the new system.

Impact of a false-positive screening mammogram on subsequent screening behavior and stage at breast cancer diagnosis.
Researchers sought to examine the impact of a false positive (FP) screening mammogram on the subsequent screening mammography behavior. They found that experiencing a FP mammogram increases the risk of late stage at diagnosis compared with prior true negative (TN) mammogram Also, women with a FP mammogram were more likely to delay their subsequent screening compared with women with a TN mammogram.
