Table 2 Correlation between the myocardial segments showing delayed enhancement on cardiac CT and at least one other imaging modality i.e. TTE, SPECT, or cardiac MRI

From: Clinical experiences of delayed contrast enhancement with cardiac computed tomography: case series

  Clinical indication Contraindication to a Cardiac MRI at the time of Cardiac CT Myocardial segments with Delayed enhancement Comparative imaging modality Myocardial segments on comparative modality
1 CAD -- Chest pain and inconclusive cardiac MRI. (MRI was not able to predict the cause of DE) Anxiety causing incomplete and inconclusive Cardiac exam Inferior wall (Transmural) SPECT MRI SPECT - Fixed perfusion defect in the inferior wall MRI – Delayed enhancement in Inferior wall. CTA – Obstructive disease in the dominant RCA
2 CM -- Progression of Sarcoidosis (new pacemaker precluded followup MRI) Permanent Pacemaker Lateral wall Apical LV wall (Patchy foci) MRI Lateral Apical left ventricular wall (Patchy foci)
3 CAD -- Assessment of ischemic scar Permanent Pacemaker Basal wall Mid lateral wall TTE Basal, lateral wall (severe hypokinesis) Apical wall (Hyper-reflective/ Increased echogenicity)
4 CM -- Hypertrophic cardiomyopathy and scar assessment AICD Basal, Mid inferior, Inferolateral, Anterolateral LV wall TTE Asymmetric septal hypertrophy.
5 CAD -- Scar mapping for ventricular tachycardia ablation AICD Basal, Mid inferolateral wall TTE Basal Mid inferolateral wall (Hyper-reflective/ increased echogenicity)
6 CM -- Idiopathic cardiomyopathy and Worsening ventricular arrhythmias. AICD Mid to apical anterior, Anteroseptal, Anterolateral LV wall TTE Apical (Akinesis) Anteroseptal (Akineis) Anterolateral wall (Hypokinesis) Septum and apex (Hyper-reflectivity/Increased echogenicity)
7 CM -- HCM, recurrent AICD shocks AICD Mid myocardium in anteroseptal Basal wall TTE Marked asymmetric LV hypertrophy.
8 CM -- Progression of Sarcoidosis Permanent Subepicardial portion of antero-septal mid ventricular wall Mid myocardial basal, Anteroseptal wall and Sub endocardial mid inferolateral wall. TTE Mid myocardial wall (Hypokinesis) Inferoposterior (Hyper-reflective/increased echogenicity)
9 CAD -- Ventricular tachycardia storm; scar assessment AICD Inferior wall and Basal to apical LV, Anterior wall at basal, mid ventricular level. TTE Inferior, septal, apical (Akinesis) Inferior and posterior wall. (Hyper-reflective/increased echogenicity)
  1. AICD = Automated Implantable Cardioverter Defibrillator, CAD = Coronary artery disease, CM = Cardiomyopathy, C-MRI = cardiac MRI, DE = Delayed enhancement, HCM = Hypertrophic cardiomyopathy, LV = Left ventricle, PM = Pace maker, TTE = Transthoracic echocardiogram, VT = Ventricular Tachycardia.
