6.8 Contrast Imaging
Injected contrast agents re-emit incident acoustic energy at a harmonic frequency much more
efficiently than the surrounding tissue. Blood containing the contrast agent stands out brightly
against a dark background of normal tissue.
Possible clinical uses are to detect and characterize tumors of the liver, kidney and pancreas
and to enhance flow signals in the determination of stenosis or thrombus.
