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) |
 |  | Pacemaker |  |  |  |
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) |
