Description/Abstract | We developed a parametric washout image which color codes regional washout, and blindly compared enhanced perfusion images in multiple projections with regional washout graphs and images in 25 patients.^Washout images permitted true spatial and anatomic assessment of regions viewed en face as well as those seen in tangent, making possible the exclusion of non-coronary irregularities and permitting evaluation of washout over the apparent cavity.^Cavitary washout was abnormal in 10 of 12 patients with apparent cavitary dilation on the post stress image, but in none without this finding.^The distribution and rotation of washout abnormalities seen over the cavity when viewed en face, and the long delay between the termination of stress and post-exercise image acquisition, suggest that apparent cavitary dilation is often related to improved visibility of the /sup 201/T1 deficient blood pool due to relative ischemia of the overlying myocardial wall. |
