Full iterative reconstruction algorithm is available, but its diagnostic quality in pediatric cardiac CT is unknown. To compare the imaging quality of two algorithms, full and hybrid iterative reconstruction, in pediatric cardiac CT. We included 49 children with congenital cardiac anomalies who underwent cardiac CT. We compared quality of images reconstructed using the two algorithms full and hybrid iterative reconstruction based on a 3-point scale for the delineation of the following anatomical structures: atrial septum, ventricular septum, right atrium, right ventricle, left atrium, left ventricle, main pulmonary artery, ascending aorta, aortic arch including the patent ductus arteriosus, descending aorta, right coronary artery and left main trunk. We evaluated beam-hardening artifacts from contrast-enhancement material using a 3-point scale, and we evaluated the overall image quality using a 5-point scale. We also compared image noise, signal-to-noise ratio and contrast-to-noise ratio between the algorithms.
Cardiac imaging: A multimodality approach
Cardiology - Wikipedia
While various automatic whole heart and great vessel segmentation frameworks have been developed in the literature, they are ineffective when applied to medical images in CHD, which have significant variations in heart structure and great vessel connections. To address the challenge, we leverage the power of deep learning in processing regular structures and that of graph algorithms in dealing with large variations and propose a framework that combines both for whole heart and great vessel segmentation in CHD. Particularly, we first use deep learning to segment the four chambers and myocardium followed by the blood pool, where variations are usually small. We then extract the connection information and apply graph matching to determine the categories of all the vessels.
Multimodality Imaging in Congenital Heart Disease e-learning course
The increasing number of survivors of congenital heart disease CHD has been paralleled by advancement of imaging modalities used for the ongoing assessment of these patients. There has been a large body of literature describing new approaches to non-invasive assessment of CHD. We will review new applications of well established as well as novel techniques for the management and understanding of CHD. The management of these patients with complex CHD with the added complexity of post-operative surgical intervention and scarring requires multimodality imaging to comprehend their physiology and anatomy.
Introduction: Congenital heart disease CHD may often present with heart failure in early childhood. This usually is related to a high pulmonary blood flow as a result of an intracardiac communication, but other cardiac lesions should also be considered. We present a 3 month old girl with a history of shortness of breath and failure to thrive. Chest X-ray showed bilateral congested lung fields.
