Quantification of microbubble concentration based on imagerie medicale ultrasound signal changes is a complex task because of the highly nonlinear image processing algorithms of ultrasound scanners. Our work at the Hammersmith Hospital, in collaboration imagerie medicale with the Department of Medical Physics at the Royal Marsden Hospital, Sutton, U.K., has focused on this area. We have developed imagerie medicale a computer-based system that allows accurate quantification of relative microbubble concentrations with power Doppler in vivo. Similarly, we have quantified relative microbubble concentrations with spectral Doppler in vivo, and we will report on this topic at the Radiological Society of North America (RSNA) meeting in December. Like contrast-enhanced MRI, kinetic studies of tumors (of the breast, for example) can be performed with Doppler ultrasound and echo-enhancers. |

| Imaging tumor vascularity with contrast-enhanced Doppler should universityof california san francisco ucsf allow much earlier assessment of treatment response than the conventional imaging criterion of reduced tumor size. Preliminary results appear to support this theory. Cosgrove et al studied 20 patients with carcinoma of the prostate and found a marked reduction of vascularity in patients undergoing universityof california san francisco ucsf hormone therapy compared with those not in treatment. Several Italian groups have universityof california san francisco ucsf used contrast-enhanced Doppler of malignant liver lesions to guide and monitor percutaneous ablation procedures.14 Functional Imaging Because microbubble echo-enhancers are blood-pool agents, they can be used as intravascular tracers to dynamically study blood flow in body organs or tumors. The real-time nature of ultrasound, combined with its high spatial resolution, makes the combination of ultrasound and microbubble agents ideally suited to functional kinetic studies of physiological indices such as transit times and, potentially, perfusion. |
