Comparative StudyFocal myocardial injury following blunt chest trauma: a comparison of indium-111 antimyosin scintigraphy with other noninvasive methods.
The diagnosis of myocardial contusion is often difficult, as traditional methods such as serial electrocardiograms, cardiac enzyme (creatine kinase [CK-MB]) analysis, and echocardiography lack sensitivity and specificity. Recent reports have shown that 111In labelled antimyosin scanning has high sensitivity for detecting cardiac injury. However, no prior studies have been reported for antimyosin imaging with patients suspected of sustaining a cardiac contusion. ⋯ Thus in patients with suspected myocardial contusion, echocardiography is frequently limited technically and the electrocardiogram and CK analysis appear to lack diagnostic accuracy. In contrast, monoclonal antimyosin imaging may be performed in patients with trauma without limitation and yields results that are concordant with echocardiograms. In patients with suspected myocardial contusion, focal antimyosin uptake is uncommon despite severe thoracic injury, which suggests that extensive myocardial necrosis is not the primary method of injury.
