17. List 2 cancer imaging technologies l.

One popular cancer imaging technology is Positron Emission Tomography (PET), which uses radioactive tracers to visualize metabolic activity in tissues. It’s especially useful for detecting cancerous cells because they tend to absorb more of the radioactive material than normal cells, making them stand out in scans. Another widely used technology is Magnetic Resonance Imaging (MRI), which employs powerful magnets and radio waves to produce detailed images of soft tissues in the body. MRI is particularly effective for examining brain tumors and spinal cord cancers, as it provides high-resolution images without the use of ionizing radiation.
