Figure 3. . Coronary radiotracer uptake in calcified proximal left anterior descending arteries.

Comparison of different radiotracers in the proximal left anterior descending artery of three different patients. The relatively low diffuse 2-(¹⁸F)-fluoro-2-deoxy-d-glucose signal (A) contrasts with enhanced focal uptake of ⁶⁸Ga-DOTATATE (modified with permission from [22]) (B) and ¹⁸F-fluoride (reproduced with permission from [55]) (C). Individual radiotracers can discriminate between the upregulation of different molecular pathways in macroscopically similar plaques.
