✦ Synopsis

Receiver o p e r a t i n g characteristic (ROC) analysis d e m o n s t r a t e d that regional variations of sensitivity exist in the detection of wall m o t i o n a b n o r m a l i t y in cardiac b l o o d p o o l imaging studies. The observer response is significantly better in the apex t h a n either the s e p t u m or p o s t e r o l a t e r a l wall segments. The observer errors tend to be false-negative in the p o s t e r o l a t e r a l wall segment and false-positive in the other two segments. Image presentation can m a k e a significant difference to the overall sensitivity, and the m o n o c h r o m e cine-sequence perf o r m e d best in this study.
