What Are the Common Imaging Techniques Used in Cancer Diagnosis?
X-ray X-ray is often the first imaging test used to diagnose bone cancer or lung cancer. It uses a small amount of radiation to produce images of the body's internal structures.
Computed Tomography (CT) CT scans provide more detailed images than X-rays. They are particularly useful in detecting cancers of the chest, abdomen, and pelvis. CT scans can also guide biopsies and monitor the effectiveness of cancer treatment.
Magnetic Resonance Imaging (MRI) MRI uses strong magnetic fields and radio waves to produce detailed images of soft tissues. It is especially useful for imaging the brain, spinal cord, and muscles. It helps in detecting and staging cancers of the central nervous system and other soft tissues.
Ultrasound Ultrasound uses high-frequency sound waves to create images of the inside of the body. It is commonly used to examine the abdomen, pelvis, and breasts. It helps in guiding biopsies and monitoring the response to treatment.
Positron Emission Tomography (PET) PET scans involve injecting a small amount of radioactive material into the body. This material accumulates in cancer cells, which are then detected by a special camera. PET scans are often combined with CT scans (PET/CT) to provide detailed information about the cancer's location and activity.
