| Echocardiography |
| Indications |
| 1st line method in all patients |
| Major Advantages |
| Widely available/repeatable |
| Real-time |
| Inexpensive |
| No-radiation |
| Major Disavantages |
| Dependent on patient's acoustic window |
| Operator-dependent |
| CMR |
| Indications |
| Fibrosis/LGE |
| Before ASA or surgery |
| DDx (phenocopies) |
| If suboptimal echo |
| Major Advantages |
| Excellent spatial and temporal resolution |
| Excellent contrast to noise ratio |
| Fibrosis (LGE and T1 mapping) |
| Major Disavantages |
| Metallic devices, foreign bodies |
| Claustrophobia |
| Adverse reactions to contrast (rare) |
| Cardiac CT |
| Indications |
| Epicardial CAD |
| Myocardial bridging |
| Septal arteries pre-ASA |
| Suboptimal echo and CMR contra-indicated |
| Major Advantages |
| Excellent spatial resolution |
| Coronary arteries |
| Major Disavantages |
| Radiation |
| Low temporal resolution |
| No standardized protocols Iodated contrast |
| CNI |
| Indications |
| Myocardial perfusion |
| DDx (phenocopies) |
| Metabolism, receptors and innervation |
| Suboptimal echo, CMR contra-indicated, CCT not available |
| Major Advantages |
| Perfusion |
| Metabolism, receptors and innervation |
| Major Disavantages |
| Radiation |
| Low temporal and spatial resolution |
