Objective To evaluate the diagnostic value of conventional and dynamic contrast- enhanced MRI in lymphoma of the orbit.Methods Thirteen cases of lymphoma of the orbit,including B-C (10 cases),T-C (1 case),T-NK-C (1 case)lymphoma,and multiple myeloma (1 case),were studied using conventional MR and dynamic contrast-enhanced MR imaging with 3D fast spoiled gradient echo sequence.Calculated values included time to peak (Tpeak),washout ratio (WR),slope and enhancement ratio (ER),and time-intensity curves (TICs),and Tpeak,WR,slope and ER were calculated preoperatively.Results Eleven of the 13 lymphomas of the orbit was seen in the anterior portion of the orbit including eyelid and lacrimal gland.On conventional MRI,10 cases showed iso-intensity on T_1WI and T_2WI and all 13 cases showed moderate enhancement after contrast administration.TIC of all 13 cases showed rapid enhancing and wash-out,Tpeak was (58.7?8.5)s,and WR was (30.9?9.4)%.The accurate diagnosis with only conventional MRI was achieved in 6 out of 13 cases,while the accurate diagnosis was achieved in all 13 cases by using combined conventional MRI and dynamic enhanment MRI.Conclusion onventional MRI combined with dynamic contrast-enhanced MRI is useful for the diagnosis of lymphoma of the orbit.
