Background

Identification of coronary plaque composition is important for selecting the treatment strategy, and 64-slice computed tomography (CT) is Chaussure Louis Vuitton Pour Homme a noninvasive method of characterizing atherosclerotic plaques. However, the correlation between plaque characteristics detected by CT and intravascular ultrasound (IVUS) is not clear. A 40 MHz IVUS imaging system (iMap-IVUS) has recently been developed to evaluate plaque composition. The aim of this study was to compare iMap-IVUS with 64-slice CT angiography for the characterization of non-calcified coronary plaques.

Methods and results

Both 64-slice CT Ceinture Lv Noir angiography and iMap-IVUS were performed in 19 patients (38 plaques). CT values were measured as Hounsfield units (HU) in circular regions of interest (ROI) drawn on the plaques. The iMap-IVUS system analyzed coronary plaques as fibrotic, lipidic, necrotic, or calcified tissue based on the radiofrequency spectrum.

A positive correlation was found between CT values and the percentage of fibrotic plaque (r = 0.34, p = 0.036) or calcified plaque (r = 0.40, p = 0.011). Conversely, a negative correlation was found between CT values and the percentage of lipidic plaque Chaussures Vuitton 2014 (r = −0.41, p = 0.01), or necrotic plaque (r = −0.41, p = 0.01).

Conclusions

Good correlations were observed between the characteristics of non-calcified plaque determined by iMap-IVUS and the CT values of plaque detected by 64-slice CT scanning.
