DEXA study: Little benefit from statins on bone health
June 3, 2025
Demonstration of colocalization of pre-existing calcification and incident intraplaque hemorrhage (IPH) in the same plaque. Axial cross sections of the same plaque at the same arterial location on a scan obtained with a T1-weighted gradient-echo noncontrast MRI sequence in a 70-year-old female participant who was free of coronary heart disease and stroke before follow-up MRI. Baseline (left) and follow-up (right) MRI examinations. The blue arrows highlight calcification in a hypointense signal area, while the green arrow indicates IPH as a hyperintense signal. The asterisks mark the lumen of the carotid artery.
