Abstract:
Cardiovascular CT acquisition protocol optimization in pediatric patients, including newborns is often challenging. This might be due to non-cooperative patients, the complexity and variety of diseases and the need for stringent dose minimization. Motion artifacts caused by voluntary and involuntary motion are most frequently seen in cardiac imaging with high heart and respiratory rates. Dual source scanners of the second and third generation are particularly well suited to respond to these challenges. This can be accomplished with advanced scan options, such as high pitch scanning, short rotation times, automated tube voltage selection, tube current modulation and iterative reconstruction.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...
Imaging Studies for Cardiovascular System I:Echocardiography
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion,...
Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
