Morphology and beyond: CT of cardiac valves


Alkadhi, H (2008). Morphology and beyond: CT of cardiac valves. Current Cardiovascular Imaging Reports, 1(2):141-148.

Abstract

Multi-detector row CT has developed into a valuable tool for noninvasive imaging of the heart. The major indication of cardiac CT represents the diagnosis or exclusion of coronary artery disease. Owing to its cross-sectional nature, the same data obtained for the coronary ­arteries contain morpho-anatomical information about the cardiac chambers and valves. When scanning in the retrospectively electrocardiography-gated mode, data can be reconstructed in various phases of the cardiac cycle. This enables assessing the movement of the open and closed valves. When performing planimetric measurements of the valve opening and regurgitant orifice areas in case of stenotic and regurgitant valves, estimations of valvular function can be given that correlate well with the results from echocardiography. This article reviews the current evidence regarding the accuracy of CT for imaging the morphology and function of the cardiac valves.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
