Figure 1 Two Examples of Plaques With Attenuation
Attenuated plaque was defined as plaque with deep ultrasonic attenuation despite absence of bright calcium. (A) Attenuation between 6 o'clock and 9 o'clock. (B) Attenuation between 5 o'clock and 8 o'clock.

Figure 2 IVUS Cross Section at the Site With Attenuation and an Adjacent Image With IVUS Criteria of Calcification
This figure shows an intravascular ultrasound (IVUS) cross section at the site with attenuation (A) and an adjacent image with IVUS criteria of calcification (B). Evidence of calcification was frequently present in the vicinity of attenuated plaques.

Figure 3 Plaque Site With Attenuation at Baseline and 2-Year Follow-Up
This figure shows a plaque site with attenuation at baseline (A) and 2-year follow-up (B). Presence of attenuation and plaque morphology is not significantly changed.
