1) Describe the limited role of CT for assessment of valvular function. 2) Discuss clinical indications where anatomic and functional valvular with CT is indicated. 3) Describe data acquisition and analysis approach for valvular assessment.
CT is a predominantly anatomic imaging modality. Compared to predominantly functional modalities its temporal resolution is limited. Also functional/4-D imaging requires retrospective gated data acquisition and is associated with higher radiation exposure.
The role of CT for functional valvular analysis is therefore limited to few clinical scenarios, where it can provide complementary information. The strength of CT in these situations is the ability for reconstruction in the acquired 3-D/4-D volume. A prominent example is transcatheter valve replacement/implantation but also assessment of prosthetic valves
