Abstract
A diagnostic method analyses the effect of intervention, e.g. by surgery, especially in the myocardium. (i) Hollow microcapsules are administered into a blood vessel of a patient having a perfusion defect, (ii) if desired, an ultrasonic image is formed of the tissue, (iii) the occlusion is at least partially removed such that the blood flow in at least one area of the tissue is increased, and (iv) an ultrasonic image of the tissue is obtained after treatment. This is based on the observation of the particular properties of the microcapsules in the myocardium. It is also the basis of providing appropriate drugs to that site.
