“…Normally, after one minute of injection, the extravascular iodine concentration exceeds the intravascular iodine concentration. 6 In regions of myocardium subtended by stenosed coronary arteries, resulting in reduced perfusion, the rate of extravascular diffusion of iodinated contrast is more pronounced. 7 Hypo-perfused myocardium (which represents reduced myocardial blood flow) is detected by simultaneous visualisation of short-axis images for regions with hypo-enhanced myocardium compared to normally enhanced remote myocardium, aided by differences in Hounsfield unit attenuation measurements ( Figure 1).…”

<p>Beyond the assessment of coronary artery anatomy, multi-detector computed tomography (MDCT) can be used to provide detailed structural evaluation of multiple non-coronary structures. The purpose of this review is to provide a clinical update on the evolving niche applications of MDCT in the assessment of non-coronary structures, including the assessment of the left ventricle for perfusion and scar, the evaluation of the right ventricle, pericardium and coronary anomalies. Additionally, the roles of MDCT in the assessment of congenital heart disease and intra-cardiac masses will be reviewed.</p>

“…Ekstravasküler dolaşımdaki iyot konsantrasyonu intravenöz (İV) enjeksiyondan yaklaşık 1 dakika sonra intravasküler iyot konsantrasyonunu geçmeye başladığından, ilk geçiş BT perfüzyonda kontrast zamanlamasının çok doğru bir şekilde ayarlanması gerekir [17]. b) Dual enerji BT ile yapılan miyokardiyal BTP tekniği Kontrast maddenin ilk arteriyel geçişi esnasında, miyokardiyal kan içeriğinin değer-lendirmesini amaçlayan bu teknikte tek bir taramada, yüksek ve düşük enerji spektrumu ile X-ışını oluşturan dual enerji modunda ça-lışabilme yeteneğine sahip cihazlar kullanılır.…”

“…18 Therefore, it is crucial to image perfusion early during the first-pass circulation or apply mathematical models that can correct for the extravascular diffusion of tracer. 19 Artifacts secondary to motion, beam hardening, and reconstruction can interfere with the relationship of CT attenuation number and iodine concentration.…”

Coronary artery disease (CAD) remains the leading cause of death in the United States. Rest and stress myocardial perfusion imaging has an important role in the non-invasive risk stratification of patients with CAD. However, diagnostic accuracies have been limited, which has led to the development of several myocardial perfusion imaging techniques. Among them, myocardial computed tomography perfusion imaging (CTP) is especially interesting as it has the unique capability of providing anatomic- as well as coronary stenosis-related functional data when combined with computed tomography angiography (CTA). The primary aim of this article is to review the qualitative, semi-quantitative, and quantitative analysis approaches to CTP imaging. In doing so, we will describe the image data required for each analysis and discuss the advantages and disadvantages of each approach.
