Doppler Ultrasound: One technique that may help predict an increased risk of cancer recurrence is Doppler ultrasound. Doppler ultrasound has been used to measure blood flow in the artery to the liver (hepatic artery) and total liver flow in patients with rectal cancer. This measurement may be helpful because abnormalities occurring in hepatic artery blood flow can be used to detect early cancer metastasis to the liver.
Has anyone had this done and if so where? My doctors have not mentioned this test to me as an option but I have read about it in articles.
