CT and MRI in the Evaluation of Thoracic Aortic Diseases
Figure 19
Giant cell arteritis—(a) axial T2-weighted double inversion recovery black blood image in a 68-year-old female patient with giant cell arteritis shows mild circumferential thickening of the ascending and descending aorta (arrow). (b) T2-weighted triple inversion recovery black blood image in the same patient with giant cell arteritis shows very minimal high signal of the descending aorta (arrow), which is consistent with mild active arteritis.
