MAGNETIC RESONANCE IMAGING DIAGNOSIS OF LUNG LESIONS IN LYMPHOMA

Aim: to study the MRI semiotics of lung involvement and compare the diagnostic effcacy of MRI, CT and PET/CT in lymphomas. Material and methods: the study included 314 patients with morphologically verifed lymphoma, who before the start of treatment underwent MRI of the whole body and CT of the thorax and/or PET/CT of the whole body. Results. The frequency of lung involvement was 14%. The lesions were in the form of nodules/masses in 76% of cases, consolidation in 29% and interstitial changes in 9%. The sensitivity, specifcity, and accuracy of MRI were 85%, 96%, and 94%, respectively, and the diagnostic effciency was high (AUC 0.901). There were no signifcant differences in the sensitivity and effciency of MRI and CT, MRI and PET/CT. Conclusion. MRI of the thorax is an effective method for diagnosing lung involvement in lymphoma and is recommended for practical use, especially in patients with variable fluorodeoxyglucose-avid lymphomas, young patients and pregnant women.
