Radiologist Hiroshi Nobusawa, MD, PhD, explains that the coronal DWIBS protocol for whole body DWI is excellent for visualizing lesions in oncology patients. “About 90% of the DWIBS exams are done in this type of patients. The remainder of DWIBS exams are performed to gain information in cases of fevers of unknown origin,” he says.
“The DWIBS sequence’s value in oncology cases is due to the high contrast it creates between lesions and surrounding tissue. Whole body DWI is requested by physicians who need to clarify TNM staging or determine therapeutic strategies, oncologists in need of diagnosis or follow-up scans, surgeons who need to see the presence of distant lesions that are sometimes difficult to detect by CT before surgery, and urologists for the evaluation of bone lesions, and the effect of chemotherapy and radiotherapy.”
