Gastrointestinal imaging-practical magnetic resonance imaging approach

Figure 20 Acute appendicitis in a pregnant patient. A: Coronal; B: Sagittal; and C: Axial single shot fast spin echo (SSFSE) T2 as well as D: fat-suppressed SSFSE T2 images. There is a blind-ended tubular structure at the retrocecal region (arrows, A, B) associated with uniform, diffuse wall thickening and dilatation, reaching up to 13 mm in diameter (C and D) as well as periappendiceal edema and small periappendiceal fluid (A-D) collection, in keeping with acute appendicitis. Edema and fluid appear significantly more conspicuous on fat-suppressed images (arrows, D). Noted is a gravid uterus (A).
