- W2969909833 abstract "AbstractSecuring the safety and efficacy of transcatheter aortic valve implantation (TAVI) on the human heart largely depends upon an accurate size estimate of the aortic annulus. Correct aortic annulus sizing is needed in order for the clinician to select a suitable prosthetic valve, where incorrect selection can lead to aortic regurgitation. To date, echocardiography and computed tomography (CT) are two imaging modalities that have been used extensively for measuring annulus size. Our contention is that fusion of both modalities may merge complementary information and produce an altogether more wholesome image of higher quality, thus facilitating a more precise measurement of aortic annulus. This paper proposes the novel idea of Echocardiography-CT image fusion for the purpose of aortic annulus sizing, and further goes to review trends and advancements in the field of medical image fusion. Research shows that fusion of two imaging modalities may provide a more accurate and complete image for diagnosis purposes. In the case of aortic annulus sizing, image fusion can potentially decrease uncertainty and minimize redundancy in the output while maximising relevant information. In the paper, we have introduced the exploratory study of using medical image fusion as an alternative method of measuring aortic annulus, as well as its challenges and related works. We found that the use of pixel-level image fusion has been effective in medical image fusion for optimising diagnostics and intervention. A number of image fusion algorithms were reviewed; from those, we can conclude that curvelet-based methods score the highest using quality assessment metrics that best associate with the human visual system (HVS), and are therefore preferred when performing image fusion.KeywordsImage fusionMultimodalityTAVIAortic stenosis" @default.
