CT imaging techniques

Preview

In patients presenting with heart failure (HF), assessment of underlying aetiology is critical for optimal management. To differentiate between ischaemic and nonischaemic dilated cardiomyopathy, invasive coronary angiography is frequently performed. This technique is currently still considered the gold standard in the detection of coronary artery disease (CAD). In addition to accurate assessment of the presence, location, and severity of coronary artery lesions, the technique also provides the opportunity for direct intervention. On the other hand, the technique carries a small but not negligible risk of complications, while in many patients no clinically relevant abnormalities will be observed. Patients presenting with unexplained dilated cardiomyopathy and a low to intermediate likelihood of CAD may therefore benefit from a noninvasive imaging approach.

To this end, anatomical imaging with CT techniques has been proposed. With this technology, high-resolution images of the coronary arteries are obtained. In addition, detailed information on cardiac structures, and to some extent also function, can be derived. The aim of the current chapter is to provide an overview of the various applications of CT technology that may be relevant in the setting of HF.
