Extension of T₂ Hyperintense Areas in Patients With a Glioma: A Comparison Between High-Quality 7 T MRI and Clinical Scans.

ABSTRACT: Gliomas are highly heterogeneous and often include a nonenhancing component that is hyperintense on T₂ weighted MRI. This can often not be distinguished from secondary gliosis and surrounding edema. We hypothesized that the extent of these T₂ hyperintense areas can more accurately be determined on high-quality 7 T MRI scans. We investigated the extension, volume, and complexity (shape) of T₂ hyperintense areas in patients with glioma on high-quality 7 T MRI scans compared to clinical MRI scans. T₂ hyperintense areas of 28 patients were visually compared and manually segmented on 7 T MRI and corresponding clinical (1.5 T/3 T) MRI scans, and the volume and shape markers were calculated and subsequently compared between scans. We showed extension of
