Comparative study reveals high T2-weighted MRI signal matching tumor invasion in postmortem malignant brain tumors, highlighting imaging value for guiding dissection.
Key Points
Histological tumor invasion without edema produced distinct high-signal intensity on postmortem T2-weighted images, identifying all confirmed neuropathological lesions.
In three cases among five whole brains, lesion enlargement was detected between final clinical scans and postmortem MRI, likely reflecting terminal disease progression.
Highlights postmortem MRI as an effective neuropathological tool that identifies subtle structural abnormalities and necrosis prior to final specimen dissection.
