An Ultrasound Imaging Technique for the Measurement of Tumors in Patients with Pancreatic Cancer or Gastrointestinal Adenocarcinoma
This clinical trial examines ultrasound imaging technique in measuring tumors in patients with pancreatic cancer or gastrointestinal adenocarcinoma. Computed tomography (CT) scans provide detailed pictures of the inside of the body using radiation, like an X-ray, and they can be used to measure cancer. Because of the cost of CT scans, and because scientists think that exposure to too much radiation and contrast material can be harmful, CT scans are normally used only once every 2-3 months to check a person’s response to treatment for their cancer. Ultrasound is a relatively low-cost imaging technique that does not involve exposure to radiation or contrast material. This study may help researchers determine if ultrasound images can be used to measures the size of pancreatic cancer or gastrointestinal tumors in the liver as accurately as CT scans.
