1 Radiologic investigation of abdominal aortic aneurysm disease: Comparison of three modalities in staging and the detection of inflammatory change  William G. Tennant, FRCSEd, George G. Hartnell, FRCR, Roger N. Baird, ChM, Michael Horrocks, MS  Journal of Vascular Surgery  Volume 17, Issue 4, Pages (April 1993) DOI: / (93) Copyright © 1993 Society for Vascular Surgery and International Society for Cardiovascular Surgery, North American Chapter Terms and Conditions

2 Fig. 1 MRI scan of inflammatory aneurysm with STIR sequence shows onion-skin appearance of inflammatory aneurysm wall. Wall displays four layers of high-signal intensity (arrow) external to lumen (L).

3 Fig. 2 MRI scan of simple aneurysm. Wall is simpler in appearance than in inflammatory cases. Only two layers of high-signal intensity (arrow) are seen external to lumen (L).

4 Fig. 3 Transverse MRI scan of abdominal aneurysm. Renal arteries are seen (arrows). Journal of Vascular Surgery  , DOI: ( / (93) ) Copyright © 1993 Society for Vascular Surgery and International Society for Cardiovascular Surgery, North American Chapter Terms and Conditions

5 Fig. 4 In vitro MRI scans of wall segments taken from inflammatory aneurysms (I) and simple aneurysms (S). Walls of simple aneurysms are featureless, whereas those of inflammatory aneurysms display banding similar to in vivo appearances.
