D) X-ray

Question

Quizplus · Accepted Answer

MRI (magnetic resonance imaging) is the best imaging device to localize a tumor in the brain as it provides highly detailed images of soft tissues, including the brain. It is non-invasive and does not involve exposure to radiation. DSA (digital subtraction angiography) is often used to visualize blood vessels in the brain but may not be suitable for tumor localization. PET (positron emission tomography) scans can reveal areas of increased metabolic activity, which can be useful in detecting tumors, but may not provide the same level of detail as MRI. X-ray imaging is not typically used to visualize the brain due to its limited ability to image soft tissues.
