Synopsis

Keywords: Tumors, Hyperpolarized MR (Gas), Xenon-129This study explored the application of hyperpolarized 129Xe (HP 129Xe) MR imaging in patients with brain tumors. HP129Xe MR and 1H MR imaging was performed on three subjects. The results showed that HP 129Xe MRI has the ability to detect brain tumors, but the HP 129Xe brain MR imaging showed the lesion range was mismatched with T2 weighted image (T2WI) and arterial spin labeling (ASL)image, these are needed to be addressed in the future.
