Can Untrasound be Useful in Detecting Cancer?

Recent research published in the journal Radiology found that the use of a new high- resolution  ultrasound device could show a “definitive difference between vessels within and surrounding tumors versus those associated with normal healthy vasculature.”  However, the method only works for tumors at a shallow depth in the tissue, such as melanoma or thyroid cancer. The device is based upon vessel bendiness or “tortuosity” and potentially offers an inexpensive non-invasive fast method to detect cancers that are less than a centimeter in size. The device is called acoustric angiogram and allows images of the blood vessels only and filters out all tissue signals, so small blood vessels can be seen clearly.  More research is planned to focus on the image depth issue and also evaluate the ability of the technology to determine a tumor”s response to treatment.
