Harmonic imaging of porcine intraovarian arteries using sonographic contrast medium: initial findings.

The purpose of this study was to visualize, using harmonic gray-scale imaging, blood flow in porcine intraovarian arteries after intravenous injections of a bubble-based sonographic contrast medium. Five female pigs underwent laparotomy. Surgically isolated ovaries were scanned intraperitoneally by an ultrasound system reconfigured with software changes to accomplish harmonic imaging.
