tect molecular signs of tumor response to therapy after only 2 days. A change in blood flow in the tumor was observed to detect response after day 14 using DCE-PI. Over the same period, standard volume measurements were not able to detect therapeutic response, and prior studies suggested that volume measurements do not become indicative of response until approximately 28 days. Thus, these methods showed a notable improvement in the early identification of tumor response to therapy, using contrast enhanced ultrasound imaging.

Although the contrast agents for USMI are not yet available in the United States, they are currently in clinical trials in Europe for cancer imaging.
