— Background
Currently, biopsies are the only definitive method to diagnose a brain tumor. While PET-CT is used for initial imaging and monitoring of the tumor, after completion of treatments, a 6-8-week delay is usually implemented to avoid false-positive results. Yet, the delay could also result in…

Researchers at Washington University in St. Louis have developed a method to improve image quality during MR imaging guided radiation therapy (MR-IGRT) by correcting for B0 fluctuation in real-time. The corrections reduce electromagnetic interference (EMI) between the MRI sc…

Researchers at Washington University in St. Louis have developed MRI post-processing software capable of imaging cellular components. The software matches specific patterns with a dictionary of signals corresponding to cellular components. While the researchers have previous…
— Background
External Beam Radiotherapy (EBR) is commonly used after surgical removal of a tumor (in e.g. a breast-conserving surgery) to control or kill malignant cells. The lack of selectivity due to irradiation of whole or partial organs from outside the body, however, is potentially damaging to t…

Researchers led by Quing Zhu at Washington University have developed a method for imaging rectal tumors using photoacoustic microscopy and ultrasound with a machine learning component. This method is better able to differentiate residual cancer from healthy tissue following…
