Gastrointestinal imaging-practical magnetic resonance imaging approach

Figure 24 Jejunal gastrointestinal stromal tumor. A: Coronal and (B) axial T2-weighted single shot fast spin echo, and (C) coronal balanced steady state free precession images as well as (D) coronal and (E) axial fat-suppressed post-gadolinium 3D-GRE T1-weighted images. There is a well-defined intramural, exophytic mass lesion arising from the proximal jejunum, in a patient with malrotation, which demonstrates intermediately increased T2 signal (arrow, A, B), early moderate hypervascularity (D) and progressive enhancement (E) post-gadolinium associated with a tiny central area of necrosis in keeping with jejunal gastrointestinal stromal tumor. Lack of proximal bowel obstruction is consistent with its eccentric origin. GRE: Gradient recalled echo.
