Cardiac gating (CT)

Cardiac gating or ECG gated angiography in CT is an acquisition technique that triggers a scan during a specific portion of the cardiac cycle. Often this technique is conveyed to obtain high-quality scans void of pulsation artefact. Technique Via the attachment of ECG leads, cardiac gating aim...

Cardiac CT (prospective high-pitch acquisition)

The prospective ECG-gated high-pitch dual-source CT cardiac angiogram is a high pitch helical acquisition of the heart that is able to capture a single phase of the cardiac cycle, a dual-source scanner is required to perform it. Although this is the CT cardiac angiogram with the lowest dose it a...

Cine imaging (MRI)

Cine imaging, a.k.a. cine sequences or cine MRI, are a type of MRI sequence acquired to capture motion. Imaging technique Cine images are obtained by repeatedly imaging the area of interest for a certain time typically within a single slice, although 3D solutions already exist 3. For the hear...

Cardiac iron overload protocol (MRI)

The cardiac MRI iron overload protocol encompasses a set of different MRI sequences for the cardiac assessment in case of suspected iron overload cardiomyopathy. Note: This article aims to frame a general concept of a cardiac MRI protocol in the above setting.  Protocol specifics will vary dep...

Transesophageal echocardiography

A standard transesophageal echocardiography (TOE, or TEE in US English) is a type of echocardiography using an endoscopic transducer, which is advanced into the thoracic esophagus, offering generally superior visualization of the great vessels and posterior cardiac structures than the standard t...

Triple-rule-out CT

Triple-rule-out CT (TRO CT) angiography may be ordered in the setting of acute chest pain to examine the thoracic aorta and the coronary and pulmonary arteries. The protocol helps exclude life-threatening causes of acute chest pain, especially if atypical, or if alternative causes to acute coron...

Cardiac imaging planes

Cardiac imaging planes are standard orientations for displaying the heart on MRI, CT, SPECT, and PET, similar to those used in echocardiography. The planes are defined in reference to the long axis of the left ventricle, which is the line that connects the ventricular apex to the center of the m...
