Myocardial perfusion imaging: contrast echocardiography today and tomorrow.
The clinical need to evaluate myocardial perfusion is not satisfied by conventional imaging techniques (I). Angiography is frequently used to provide qualitative anatomic data, but it lacks a physiologic basis for assessing regional blood flow and is an unreliable predictor of it (2,3). Recent technical advances in contrast echocardiography permit direct perfusion assessment and promise to prov...

متن کاملQuantifying myocardial perfusion using contrast echocardiography.
There is a complex relation between what can be seen using perfusion imaging techniques, and what can be measured.
متن کاملNovel quantitative assessment of myocardial perfusion by harmonic power Doppler imaging during myocardial contrast echocardiography.
OBJECTIVE To test the hypothesis that the power of the received signal of harmonic power Doppler imaging (HPDI) is proportional to the bubble concentration under conditions of constant applied acoustic pressure, and to determine whether a new quantitative method can overcome the acoustic field inhomogeneity during myocardial contrast echocardiography (MCE) and identify perfusion abnormalities c...
متن کاملAssessment of transmural distribution of myocardial perfusion with contrast echocardiography.
BACKGROUND We hypothesized that by using our newly defined method of destroying microbubbles and measuring their rate of tissue replenishment, we could assess the transmural distribution of myocardial perfusion. METHODS AND RESULTS We studied 12 dogs before and after creation of left anterior descending coronary artery stenoses both at rest and during hyperemia (n=62 stages). Microbubbles wer...
