Instead of taking 1 or 2 pictures, like a regular x-ray, a CT scanner takes many pictures and a computer then combines them to show a slice of the part of your body being studied. Computed tomography (CT) scanĪ CT scan uses x-rays to make detailed cross-sectional images of your body. This problem can be helped with surgery or an endoscopy procedure. This can lead to frequent coughing, gagging, or even pneumonia. Anything that is swallowed can then pass from the esophagus into the windpipe and lungs. This occurs when the tumor destroys the tissue between the esophagus and the trachea (windpipe) and creates a hole connecting them. This test can also be used to diagnose one of the more serious complications of esophageal cancer called a tracheo-esophageal fistula. Early cancers can look like small round bumps or flat, raised areas (called plaques), while advanced cancers look like large irregular areas and can cause narrowing of the inside of the esophagus. This test can show even small, early cancers. This test can be done by itself, or as a part of a series of x-rays called an upper gastrointestinal (GI) series, that includes the stomach and part of the intestineĪ barium swallow test can show any abnormal areas in the normally smooth inner lining of the esophagus, but it can't be used to determine how far a cancer may have spread outside of the esophagus. When x-rays are taken, the barium outlines the esophagus. In this test, you will be asked to swallow a thick, chalky liquid called barium to coat the walls of the esophagus. If you're having trouble swallowing, sometimes a barium swallow is the first test done. To look for possible signs of cancer coming back after treatment.To help determine if the treatment is working.To learn how far cancer might have spread.To look at a suspicious area that might be cancer.Imaging tests might be done for a number of reasons both before and after a diagnosis of esophageal cancer, including: Imaging tests use x-rays, magnetic fields, sound waves, or radioactive substances to create pictures of the inside of your body. You may also be referred to a gastroenterologist (a doctor specializing in digestive system diseases) for further tests and treatment. These could include imaging tests and/or biopsies of the esophagus. If the results of your history and physical exam suggest you might have esophageal cancer, more tests will be done. Your doctor will also examine you closely to look for possible signs of esophageal cancer and other health problems. If you have symptoms that might be caused by esophageal cancer, the doctor will ask about your medical history to learn about your symptoms and possible risk factors. If cancer is found, further tests will be done to help determine the extent ( stage) of the cancer. If esophagus cancer is suspected, exams, tests, and a biopsy (a sample of esophagus cells) will be needed to confirm the diagnosis. Esophagus cancers are usually found because of signs or symptoms a person is having.
