What is a common imaging technique used for cancer diagnosis?

CT scans are widely used in cancer diagnosis due to their ability to provide detailed cross-sectional images of the body, which can reveal the presence, size, and location of tumors. This imaging technique uses a combination of X-rays and computer technology to create images that can help differentiate between normal and abnormal tissues. The detailed images provided by CT scans allow oncologists to assess the extent of the disease, plan treatment, and monitor response to therapy.

While MRI scans, ultrasound, and X-rays are also valuable imaging tools in oncology, they each come with specific limitations and are often used for particular types of tumors or specific diagnostic purposes. MRI is particularly useful for imaging soft tissues, ultrasound is frequently used for superficial masses, and X-rays are better suited for examining the bones or identifying certain types of lung cancers. CT scans, however, strike a balance by offering comprehensive insights across multiple organs and structures, making them a common choice in cancer diagnostics.
