MDCT imaging characteristics of different degrees of CAC. A Shows the CT image of a patient with CACS = 0, indicating no coronary calcification; B CACS = 145.3 points, high-density calcification shadows can be observed; C CACS = 901.2 points, indicating calcification in multiple coronary arteries; D CACS = 2842.5 points, which was the highest CACS patient in this study. Large areas of coronary calcification are visible, indicating poor cardiovascular prognosis may occur in the later stage. Red arrow, imaging of calcified vascular)
