Core Tip
Core tip: To the best of our knowledge, there has been no direct comparison between peak systolic velocity and time average maximum mean velocity in their ability to predict abnormalities on magnetic resonance imaging (MRI)/magnetic resonance angiogram in children with sickle cell disease. With the growing clinical use of MR Angiography to assess sickle cell patients, the sensitivity of Trans Cranial Doppler (TCD) should be maximized if it is to maintain its role as a screening test in the sickle cell population. Based on the data obtained at our institution and using the assumption that the best screening test is the one with the highest sensitivity, the peak systolic velocity could be the measurement of choice for TCD screening.
