BRAIN TUMORS CAN BE LOCATED BY USING AN ISOTOPE OF

• A. carbon – 14
• B. iodine 131
• C. technetium 99 ✓
• D. uranium235
• E. uranium 238

The answer to the question is: C. technetium 99

Technetium 99m is the isotope used to locate brain tumors. Technetium 99m is a radioactive isotope that emits gamma rays, making it suitable for medical imaging. It has a short half-life of about six hours, which allows for imaging without prolonged radiation exposure to the patient. Technetium 99m is commonly used in single-photon emission computed tomography (SPECT) scans to detect brain tumors and other abnormalities in the brain.

The process involves injecting a small amount of technetium 99m into the patient’s bloodstream. The isotope then accumulates in areas of high metabolic activity, such as tumors, allowing for their visualization using specialized imaging equipment. This technique provides valuable information for diagnosing and monitoring brain tumors.
