Abstract:
:Though long considered unlikely because of the resonance pattern of agents such as SonoVue, high frequency applications for small parts and intracavitary applications now seem very promising. Excellent non-linear signals can be obtained at 7 MHz and higher using recently developed CPS software, and preliminary results suggest that this may prove useful for assessing superficial lymph nodes, the thyroid and parathyroid, breast masses and many superficial masses including those in the skin. Some other potentially useful "fringe" applications of the now-familiar transabdominal transducers with CPS are the pancreas, gall bladder and spleen, though these have not been investigated formally as yet.
