Editorial Comment

The principle aim of diagnostic cardiovascular imaging is to provide clinically relevant information regarding cardiac anatomy and function. This may be broadly categorised into coronary vascular anatomy, plaque architecture, myocardial perfusion, cavity volume, valvular pathology, and haemodynamics. Each of the major cardiac imaging techniques (chest X-ray, coronary angiography, cardiac MRI, multi-slice CT, SPECT, FDG-PET, echocardiography) provides a subset of this information to varying degrees according to strengths and weaknesses of the particular modality. The techniques may be compared by invasiveness, spatial resolution, temporal resolution, radiation dose, cost, repeatability, and availability.

In this issue of IJCIBansal et al. report their study comparing 16-slice multi-detector computed tomography (16CT) with conventional 2-dimensional echocardiography for assessment of left ventricular function by cavity volumes and ejection fraction. Their study population consisted of...
