title: [MRI of splenomegaly].
abstract: Splenomegaly was evaluated by a 0.1 T MR system using multi-echo SE image. (TR = 1500 msec., TE = 40, 80 and 120 msec.) Calculated measurement of T2 relaxation time was obtained. Material consists of 32 cases including 14 liver cirrhosis, 3 chronic myelocytic leukemia, 1 malignant lymphoma and 14 normals. 1) T2 value of normal spleen measured 113.7 +/- 5.68 msec. 2) Splenomegaly due to congestion had the prolonged T2 value of 122.6 +/- 10.25 msec. 3) T2 value of splenomegaly with malignant cell infiltration such as leukemia and lymphoma were shorter than normal spleen. Good histological correlation was obtained in MRI findings of splenomegaly due to congestion and malignant cell infiltration.
