Abstract |
Visual assessment of regional wall motion abnormality
(RWMA) by gated blood pol scan (GBPS) serves as an
useful parameter in thc diagnosis, functional
evaluation, and follow up in various clinir.al
settings, but are still subject to some inherent
limitations. On important problem may be the
interobserver as well as intraobsever variation that
may well be present due to the subjective nature of the
interpretations. This study was carried out to
determine the reliability and reproducibility of visual
assessments made in GBPSs, and to observe the degree to
vihich the results would be influenced by observer
variation. Fifty two patients with coronary heart
disease had resting GBPS and contrast ventriculography
v;ithin 4 days appart. Contrast ventriculography showed
normal wall motion in 6 patients and the remaining 46
had RWMA in one or more segments. The anterior and left
anterolateral views of all 52 GBPSs were analyzed by
three independent observers, who selected from 5
scales, their 1nel of confidence that there was RWMA in
that segment. Reciever operating characteristic (ROC)
curves for each analysis was plotted and the area under
the curue (B) was used as a parameter representing each
