Brain scan may replace biopsy for tumor grading

Summary
Gliomas are the most common primary brain tumors in adults, and knowing whether a tumor is low-grade or high-grade before surgery guides treatment and prognosis. Currently, doctors need a tissue sample from surgery or biopsy to grade a glioma, and standard MRI scans often cannot tell the difference reliably. This study tests whether an advanced MRI technique called susceptibility-weighted imaging (SWI) can grade gliomas non-invasively by detecting tiny blood vessel changes and microbleeds that are more common in high-grade tumors. About 90 adults with suspected gliomas will receive a preoperative brain MRI that includes SWI, and two radiologists will grade the images without knowing the pathology results. Researchers will then compare the imaging grades against the final tissue diagnosis to measure how accurate SWI is.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- susceptibility-weighted imaging (SWI), an advanced MRI scan
- What this could lead to
- If SWI proves accurate, doctors could grade gliomas before surgery without a tissue sample, helping plan operations and treatment sooner.
- What could go wrong
- This is a small observational study at one center. SWI may not match pathology results closely enough, and findings might not hold in other hospitals or MRI machines.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Adult patients aged 18 years and older. * Neuroimaging (CT or MRI) findings suggestive of cerebral glioma. * Patients scheduled for surgical resection or stereotactic biopsy. Exclusion Criteria: * Previous brain surgery for the same lesion. * Previous cranial radiotherapy or chemotherapy. * General contraindications to MRI (e.g., cardiac pacemakers, ferromagnetic implants, or severe claustrophobia). * Poor-quality MRI examinations compromised by significant motion or susceptibility artifacts.
