A Couple Of Scary Yet , Creative AZ191 Guidelines

2 The interquartile ranges (IQRs) of necrotic core and fibrous plaque were 29 to 81?HU and 104 to 185?HU, respectively. Thus, AZ191 (Table?1). The sensitivity, specificity, and accuracy of these attenuation values to identify necrotic core were 25%, 98%, and 71%, respectively, for find more fibrous tissue compared with 100-kV SECT on plaques with borderline attenuation values, defined as >37?HU (the lowest fibrous plaque attenuation) and Apoptosis Compound Library supplier mean heart rate of 64 �� 9.4 beats/min, mean scan quality of 1.9 �� 0.7 (scale, 1�C4), mean noise of 16.8 �� 4.6?HU, and mean dose-length product of 663.7 �� 119.3?mGy ? cm, giving a mean effective dose of 7.8 �� 3.8?mSv. In comparison with conventional SECT at our institute, no difference was found in the mean image noise of DECT vs SECT (16.8 �� 4.6?HU vs 16. �� 6.2?HU; P?= .85), but DECT displayed significantly lower image quality (mean quality score, 1.9 vs 3.4). Three-vessel VH-IVUS yielded 60 plaques from 20 patients. In 18 of the 60 co-registered plaques, DECT image quality was too poor to allow plaque analysis. Of the remaining 42 plaques, VH-IVUS found that 31 plaques (74%) contained significant necrotic core. The most accurate attenuation threshold for necrotic core (
