Imaging Procedures and Findings
Axial contrast-enhanced chest CT images obtained at level of heart show sharply demarcated area of decreased enhancement in anterior wall of left ventricle, apex and interventricular septum consistent with acute MI. Notice that the ventricular wall does enhance at some levels.
Initial acute MI is detectable on contrast-enhanced chest CT as a focal area of decreased left ventricular myocardial enhancement in a specific coronary arterial distribution. This finding is clinically relevant because contrast-enhanced chest CT is performed for indications such as suspected pulmonary embolism and aortic dissection, which have clinical features that overlap those of acute MI. Atypical presenting symptoms occur in 20??60% of patients with acute MI this trend is especially true for women. If acute MI is evident on CT, the diagnosis can be suggested, leading to appropriate triage of the patient. acute MI is detectable on contrast-enhanced chest CT as decreased left ventricular enhancement in a specific coronary artery distribution, related to the clinical infarct.
