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 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...
متن کاملMyocardial contrast echocardiography: advantages of quantitative analysis.
Every technology yet to be consolidated needs to be compared with reference methods to evaluate its accuracy. Over the past years, contrast echocardiography has been compared against a variety of standards. In experimental studies, myocardial perfusion data from ultrasound have been compared with the measurements of coronary blood flow obtained by labeled microspheres, or with infarct size foll...
متن کاملPrognostic value of dobutamine stress myocardial contrast perfusion echocardiography.
BACKGROUND Myocardial perfusion (MP) imaging with real-time contrast echocardiography (RTCE) improves the sensitivity of dobutamine stress echocardiography for detecting coronary artery disease. Its prognostic value is unknown. We sought to determine the value of MP and wall motion (WM) analysis during dobutamine stress echocardiography in predicting the outcome of patients with known or suspec...
