Diagnostic tools

Our team of esophageal cancer experts uses sophisticated diagnostic technology to evaluate tumors and develop your individualized treatment plan. Throughout your treatment at City of Hope, we use imaging and laboratory tests to track the size of the tumors, monitor your response to treatment and modify your treatment if needed.

Some of the diagnostic tests available to esophageal cancer patients at City of Hope include:

CT scan

A CT scan is a common tool for the screening, diagnosis and treatment of esophageal cancer. A CT scan is an X-ray procedure that uses a computer to produce three-dimensional, cross-sectional images of the inside of your body.

Endoscopic ultrasound (EUS)

An EUS allows a doctor to see the esophagus and surrounding tissues on an ultrasound machine. This test for esophageal cancer is effective in detecting abnormalities in the surrounding tissue and lymph nodes. An EUS also helps stage esophageal cancer.

MRI

MRI technology uses radiofrequency waves, powerful magnets and a computer to create detailed, cross-sectional pictures and is able to distinguish between normal and diseased tissue. An MRI is especially useful in the detection of esophageal tumors and metastases.

PET/CT scan

A PET/CT scan for esophageal cancer creates detailed, computerized pictures of your esophagus, allowing your doctors to identify where healthy tissue ends and the tumor begins. A PET/CT scan provides a more detailed picture of cancerous tissues in a single scan than either a CT or PET scan alone. 

Upper endoscopy

Upper endoscopy uses an endoscope (a thin, tube-like device equipped with a camera) to examine your upper digestive system. The endoscope is inserted into your body through your mouth to look for signs of illness in certain areas, such as your esophagus. The camera on the end of the endoscope allows your doctors to see the lining of your esophagus and helps detect abnormalities.
