Distinguishing Recurrent Glioma From Post-Radiation Change: Can Advanced MRI Techniques Predict Outcome?
- Newly or previously diagnosed malignant glioma, WHO grades II-IV based on pathology confirmation
- Newly or previously treated with standard fractionated radiation therapy
- Karnofsky performance status score >60
- Unable to provide a written informed consent; or under the care of a parent or legal guardian who is unable to provide written consent
- Not suitable to undergo MRI or use the contrast agent Gadolinium because of:
- Presence of metallic objects or implanted medical devices in body (i.e., cardiac pacemaker, aneurysm clips, surgical clips, prostheses, artificial hearts, valves with steel parts, metal fragments, shrapnel, tattoos near the eye, or steel implants)
- History of severe allergic reaction to intravenous contrast (iodine or gadolinium)
- Renal failure
- Reduced renal function, as determined by GFR < 30 mL/min/1.73 m2 based on a serum creatinine level obtained within 28 days prior to registration.
- Presence of serious systemic illness, including: uncontrolled intercurrent infection, uncontrolled malignancy, significant renal disease, or psychiatric/social situations which might impact the survival endpoint of the study or limit compliance with study requirements.
