3D Imaging Technologies in Atherosclerosis by Rikin Trivedi

By Rikin Trivedi

Atherosclerosis represents the prime reason for mortality and morbidity on this planet. of the most typical, critical, ailments that can take place, acute myocardial infarction and stroke, have their pathogenesis within the atherosclerosis which could have an effect on the coronary arteries in addition to the carotid/intra-cranial vessels. accordingly, some time past there has been an intensive study in deciding on pre-clinical atherosclerotic illnesses so one can plan the proper therapeutical process prior to the pathological occasions happen. within the final two decades imaging recommendations and specifically Computed Tomography and Magnetic Resonance had a huge development of their strength. within the box of the Computed Tomography the advent of the multi-detector-row expertise and extra lately using twin power and multi-spectral imaging presents a gorgeous point of anatomic element. The MR due to using energy magnetic box and intensely complicated sequences can picture human vessels in a short time whereas supplying a very good distinction solution. ​

Intracoronary ultrasonography (ICU) is a complementary examination that allows the evaluation of plaque morphology and the assessment of the coronary walls. These fundamental tools have the disadvantages of being invasive (in fact they are based on the selective catheterisation of the coronary arteries through an arterial access, which generally is the brachial or the femoral artery) and not without intraoperative and postoperative complications, such as plaque rupture followed by thrombosis in situ and ischemia, death and infections.

Porcu et al. segments 5, 6, 11 and 12, meanwhile RCA (when it is dominant) supplies segments 3, 4, 9, 10 and 15 [6]. The segment 17 can be supplied by any of the three arteries, but generally is assigned to the LAD [6]. The Coronary Artery Calcium Score The CACS is a method of evaluation of the amount of calcium localised in the coronary arteries, which is indicative of the risk of cardiac major events [7], but its use in clinical practice is controversial [8].
