Contrast-enhanced computed tomography assessment of aortic stenosis [PDF]
Heart, 2021 Objectives Non-contrast CT aortic valve calcium scoring ignores the contribution of valvular fibrosis in aortic stenosis. We assessed aortic valve calcific and non-calcific disease using contrast-enhanced CT. Methods This was a post hoc analysis of ...

Bone segmentation in contrast enhanced whole-body computed tomography [PDF]
Biomedical Physics & Engineering Express, 2022 Abstract Segmentation of bone regions allows for enhanced diagnostics, disease characterisation and treatment monitoring in CT imaging. In contrast enhanced whole-body scans accurate automatic segmentation is particularly difficult as low dose whole body protocols reduce image quality and make contrast enhanced regions more difficult ...

Contrast enhancement of soft tissues in computed tomography images [PDF]
SPIE Proceedings, 2006 Even though soft tissues are of primary interest to radiologists, they are represented using only 12.5% of the total number of gray levels in a typical DICOM format of a Computed Tomography (CT) scan. This poor distribution of gray levels reduces the overall contrast and the texture differences between individual organs, and poses a serious ...

Role of MDCT in Detection and Characterisation of Focal Liver Lesions [PDF]
Journal of Clinical and Diagnostic Research, 2019 Introduction: Multiphasic Computed Tomography (CT) has become the primary imaging modality for detection and characterisation of focal liver lesions. CT has assumed primary role in evaluating hepatic masses.
