Ultrasound for colorectal cancer
If there is fluid in your abdomen, your doctor may use this diagnostic tool, which produces images of internal organs from high-energy sound waves and echoes. Our doctors use ultrasound technology to check for tumors in abdominal organs, such as the liver, gallbladder and pancreas.
What is an ultrasound?
This versatile imaging technology uses high-frequency sound waves to produce images of organs and tissues within the body. By capturing images in real time, ultrasound exams reveal the structure and movement of the body's internal organs, such as the heart, blood vessels, kidneys and liver.
Ultrasound can also be used to precisely locate the position of a tumor in order to guide a biopsy or aspiration procedure. For example, ultrasound may be used to mark out the boundaries of a tumor prior to its removal. It can also be used to administer cancer treatments.
Depending on the body part being examined, some types of ultrasound include: abdominal, breast, cardiac, pelvic, prostate, renal, testicular and thyroid. Unlike X-rays, ultrasound exams do not use radiation.
