  		Figure 1 {Delta}T in Lesions With Negative and Positive Remodeling

Difference between atherosclerotic plaque temperature and background temperature ({Delta}T) in patients with negative remodeling and those with positive remodeling. The bottom of each box represents the first quartile, the top of the box represents the third quartile, and the line in the box represents the median value of {Delta}T.

  		Figure 2 {Delta}T in Patients With ACS and CSA

Difference between atherosclerotic plaque temperature and background temperature ({Delta}T) in patients with acute coronary syndromes (ACS) and those with chronic stable angina (CSA). The bottom of each box represents the first quartile, the top of the box represents the third quartile, and the line in the box represents the median value of {Delta}T.

  		Figure 3 Temperature Measurements Stratified by Clinical Syndrome and Remodeling Index

The {Delta}T stratified by clinical syndrome and remodeling index. The bottom of each box represents the first quartile; the top of the box represents the third quartile, and the line in the box represents the median value of {Delta}T. Abbreviations as in Figure 1.

  		Figure 4 Correlation of {Delta}T and Ri

Remodeling index (Ri) is positively correlated with the difference between atherosclerotic plaque temperature and background temperature ({Delta}T) (p < 0.01; r = 0.59).

  		Figure 5 {Delta}T in Nonruptured and Ruptured Plaques

The presence of ruptured plaque is associated with increased {Delta}T both in patients with ACS and in those with CSA (p < 0.01). The bottom of each box represents the first quartile, the top of the box represents the third quartile, and the line in the box represents the median value of {Delta}T. Abbreviations as in Figures 1 and 2.
