摘要： A method of contrast agent-enhanced imaging involving induction of vasomodification, e.g. by physical or pharmacological means, in which pre- and post-vasomodification images in respect of free-flowing contrast or tracer agent in a substantially steady state distribution are recorded as part of a single imaging sequence and are compared to identify any local variations resulting from changes in vascular volume caused by the vasomodification. Imaging techniques which may be employed include ultrasound imaging, magnetic resonance imaging, X-ray imaging and nuclear tracer techniques such as scintigraphy.

摘要： Prostate abnormalities such as cancer may be detected by ultrasonic determination of the in-flow kinetics of contrast agent-containing blood in the prostate and/or by observation of disease-related asymmetries in the spoke-like vascular pattern of the prostate.
