Values given here are approximations from commonly used techniques.
+ = may be useful in selected clinical scenarios, but with significant limitations; ++ = useful modality but with some limitations; +++ = routinely performed now, or can be readily adopted in clinical practice; − = major limitation in the modality, making it difficult to be adopted in clinical practice; 2D = 2-dimensional; 3D = 3-dimensional; CMR = cardiac magnetic resonance; CT = computed tomography; LA = left atrium; TDI = tissue Doppler imaging.
↵⁎ The actual temporal and spatial resolutions depend on the specific imaging parameters used in each modality.
