Abstract :

Aim: In a previous study Dual Energy CT is employed to determining effective atomic number and electron density of atherosclerotic coronary artery plaque which is based on the measurement of linear attenuation coefficient of the atherosclerotic coronary artery plaque at two different energies. This study explores the way to measure the electron density of tiny and porous coronary plaque and verifies the Dual Energy CT – non invasive method of determination of electron density. Density of plaque so obtained by Dual Energy CT was verified, by pycnometry method which was utilized to independently measure the actual density of plaques. The reliability of pycnometry method was also further standardized. This study, being first of its kind reports the actual density of coronary artery plaque and the results clearly show the consistency between Dual Energy CT results and of pycnometry measurement. This indicates that electron density as obtained by Dual Energy CT can be used to characterize the plaque and proves the reliability of the method applied for calculating ρe and Zeff from Dual Energy CT data, it can be applied to gather vast information for clinical purpose
