Other imaging techniques such as Magnetic Resonance Imaging (MRI), Positron Emission Tomography (PET) scans, and Ultrasound are also used in cancer diagnosis and treatment. Each modality has its advantages and limitations. For instance, MRI provides better soft tissue contrast without radiation but is more time-consuming. PET scans are excellent for detecting metabolic activity and the spread of cancer but are often combined with CT for better anatomical detail.
