Several imaging techniques are commonly used in the context of brain cancer:
Magnetic Resonance Imaging (MRI): This technique uses powerful magnets and radio waves to create detailed images of the brain. MRI is particularly useful for identifying brain tumors and assessing their impact on surrounding structures. Computed Tomography (CT) Scan: CT scans use X-rays to create cross-sectional images of the brain. They are often used in emergency settings to quickly detect brain tumors, bleeding, or swelling. Positron Emission Tomography (PET) Scan: PET scans involve injecting a radioactive tracer into the bloodstream to highlight areas of high metabolic activity, which can indicate the presence of cancer cells. Functional MRI (fMRI): This technique measures brain activity by detecting changes in blood flow. It is valuable for mapping functional areas of the brain, particularly when planning surgery. Single Photon Emission Computed Tomography (SPECT): SPECT scans use a radioactive substance and a special camera to create 3D images, helping to identify abnormal brain activity and tumor growth.
