MR evaluation of the mediastinal lymph nodes.

摘要: Clinico-radiological profile of 25 patients with mediastinal lymphadenopathy due to tuberculosis, Hodgkin's lymphoma and metastases is presented. The main objective was study the signal intensity pattern lymph nodes both in plain contrast enhanced magnetic resonance imaging (MRI), find out its potential value diagnosis. Fifteen tuberculous lymphadenopathy, 5 metastatic were studied by 1.5 T Siemens, Magnetom. Both enhancement evaluated. Tuberculous appeared isointense T1WI T2WI. On administration multiple hypointense foci seen 14 15 patients. revealed solitary or hyperintense central T2WI, whereas lymphomatous heterogenous intensity. Though mild moderate type enhancement, dense which noncontrast images. Hence, MR characteristics may be useful index evaluating aetiology lymphadenopathy.
