BACKGROUND: Patients with common variable immunodeficiency (CVID) have an increased incidence of pulmonary infections and require frequent follow-up computed tomography (CT) scans.
PURPOSE: To evaluate the diagnostic performance of 3-T magnetic resonance imaging (MRI) in patients with CVID.
MATERIAL AND METHODS: In this prospective study, 3-T MRI was performed in 20 patients with CVID. The patients were imaged with CT and MRI scans on the same day. The MRI protocol included a T2-weighted HASTE sequence (TR=1400 ms, TE=95 ms, slice thickness (ST)=3 mm), T2-weighted BLADE sequence (TR=5379 ms, TE=100 ms, ST=3 mm), and 3D VIBE sequence (TR=3.9 ms, TE=1.32 ms, ST=3 mm). Mediastinal and parenchymal changes were compared. A modified Bhalla scoring system was used in the evaluation of CT and MRI scans.
RESULTS: A total of 17 (85%) patients had parenchymal abnormalities identified by CT or MRI. Similar findings were detected with CT and MRI in the assessment of the severity of bronchiectasis (P=0.083), bronchial wall thickening (P=0.157), and mucus plugging (P=0.250). Consolidations were detected with both modalities in all patients. There was excellent concordance between the two modalities in the evaluation of nodules >5 mm (nodule size 5-10 mm, P=0.317; nodule size >10 mm, P=1). However, MRI failed to detect most of the small nodules (<5 mm).
CONCLUSION: 3-T MRI detected mediastinal and parenchymal alterations in patients with CVID and provided findings that correlated well with CT. Despite a few limitations, MRI is a well-suited radiation-free technique for patients requiring longitudinal imaging.
