The Spleen Revisited: An Overview on Magnetic Resonance Imaging
Figure 16
Lymphoma. Axial T2wi SSFSE (a), axial pre- (b) and postcontrast T1wi 3D-GRE with fat suppression in the arterial (c) and venous (d) phase. Coronal fat-suppressed T1wi 3D-GRE in the interstitial phase (e). The spleen is enlarged. Lymphomatous nodules are isointense to splenic parenchyma on T1wi (b) and T2wi (a). One nodule is moderately hypointense T2wi (arrow, (a)). This feature aids in distinction against metastatic lesions, which are commonly hyperintense. Lymphomatous lesions demonstrate hypovascular nature with lower signal intensity relative to normal spleen on postcontrast images ((c), (d) (e)), thereby increasing conspicuity.
