Preoperative and intraoperative decision making with Dual Source CT
Transcatheter tricuspid valve interventions are rapidly evolving and with that the need for imaging is increasing, to accurately assess the anatomy of the valve and the right ventricular function, especially in patients with a high surgical risk.1,2
Experience how Dual Source CT enables the evaluation of challenging valves thanks to its ultra-high intrinsic temporal resolution.
Dual Source Dual Energy in the evaluation of myocardial fibrosis
The assessment of myocardial extracellular volume (ECV) fraction has been studied as a new approach towards the noninvasive evaluation of myocardial fibrosis. MRI as the noninvasive standard for the assessment of ECV has some known limitations and contra-indications.3 Dual Source CT could be your cost-effective alternative offering higher spatial resolution.
Fractional Flow Reserve assessment with Dual Source CT
78% of FFRCTs rejections are caused by motion artifacts due to poor temporal resolution.4 Benefit from outstanding visualization of coronaries leading to a unique acceptance rate of up to 99% with Dual Source CT.
Visualization of intracardiac thrombi with Dual Source Dual Energy
Transesophageal echocardiography (TEE) is considered the gold standard imaging modality used prior to catheter ablation to exclude the presence of thrombi in the left atrium or left atrial appendage.
However, this modality is semi-invasive, time-consuming, and uncomfortable for patients. Dual Source CT is a fast, non-invasive alternative providing complete visualization of left atrium, left atrial appendage and pulmonary veins.5Assessment of congenital heart disease with Dual Source CT
In addition to the general challenges for cardiac MRI in pediatrics, structures such as the coronary arteries of neonates may be difficult to visualize with the lower spatial resolution of MRI. The latest studies have shown that Dual Source CT allows for free breathing acquisitions at low dose and high accuraccy.6,7
Cardiac imaging - When real temporal resolution matters
How do you tackle cardiac imaging challenges posed by tachycardia patients or children with high heart rates – when the diastolic phase is simply too short or unpredictable for conventional CT scans?
Dual Source CT offers such high native temporal resolution that you can simply turn to the systolic phase and generate high quality images with fewer motion artifacts. Discover ten clinical scenarios where this unique capability of Dual Source CT can make a difference – compiled in an exclusive and easy to read whitepaper.
DSCT in cardiac imaging
Dual Source CT provides the right cardiac acquisition, for the right patient, for the right clinical indication.
Heart disease is a growing concern. How do you achieve optimal procedural planning with a diverse patient mix? How do you get high-quality images even when facing the challenge of cardiac motion?
DSCT was designed to answer these challenging questions through industry-leading native temporal resolution and precision.
Watch the video to learn how to acquire high-quality images for even the most challenging and advanced cardiac applications.
