Figure 1.
One magnetic resonance imaging scan, one computed tomography scan, and four ultrasound images. The images show the left carotid artery inflammation at diagnosis and after four weeks of treatment. Panel A: Axial cervical view of magnetic resonance imaging showing circumferential parietal thickening of the left carotid artery wall with a white arrow indicating the thickening. Panel B: Axial cervical view of computed tomography scan showing the same thickening. Panel C: Ultrasound image showing the thickening with a white arrow. Panel D: Doppler ultrasound image showing the thickening with a color-coded scale indicating blood flow. Panel E: Axial ultrasound view showing regression of wall thickening after treatment, with measurements indicated. Panel F: Longitudinal ultrasound view showing further regression of wall thickening after treatment.
Imaging of perivascular inflammation of the left internal carotid artery at diagnosis and at 4 wk of treatment. (A–F) At diagnosis: circumferential parietal thickening (white arrows) of the left carotid artery wall on axial cervical views of MRI (A), CT scan (B), US (C), and Doppler (D). At midterm treatment: regression of wall thickening on axial (E) and sagittal (F) US views.
