Contrast-Enhanced Liver Magnetic Resonance Image Synthesis Using Gradient Regularized Multi-Modal Multi-Discrimination Sparse Attention Fusion GAN

Changzhe Jiao, Diane C. Ling, Shelly X. Bian, April Keiko Vassantachart et autres

PURPOSES: To provide abdominal contrast-enhanced MR image synthesis, we developed an gradient regularized multi-modal multi-discrimination sparse attention fusion generative adversarial network (GRMM-GAN) to avoid repeated contrast injections to patients and facilitate adaptive monitoring. METHODS: With IRB approval, 165 abdominal MR studies from …

A comprehensive review of 30 years of pediatric clinical trial radiotherapy dose constraints

April Keiko Vassantachart, Arthur J. Olch, Marjorie T. Jones, Christophe Marques et autres

BACKGROUND: Radiation therapy normal tissue dose constraints are critical when treating pediatric patients. However, there is limited evidence supporting proposed constraints, which has led to variations in constraints over the years. In this study, we identify these variations in dose constraints within …
