<prompt> Answer this question truthfullyIs Hepatocellular Carcinoma diagnosed with Echocardiography or Ultrasound?  <response>: <reason> Echocardiograms may be helpful in the measurement of ejection fraction and identification of ischemic and hypokinetic areas of the ventricles. This is useful in establishing a diagnosis of congestive cardiac failure because of the underlying cause of liver cirrhosis. Contrast echocardiography is a useful diagnostic test for hepatopulmonary syndrome: Intravenous microbubbles 10 micrometers in diameter from agitated normal saline that are normally obstructed by pulmonary capillaries normally 8 to 15 micrometers rapidly transit the lung and appear in the left atrium of the heart within 7 heart beats. Intravenous technetium -99mlabeled albumin may transit the lungs and appear in the kidney and brain.
