[Abstract] Objective: To explore the performance of pulmonary MR imaging with free-breathing T1-weighted star vibe sequence and computed tomography (CT) in the assessment of pulmonary parenchyma diseases.Materials and Methods: 30 consecutive patients with various pulmonary parenchyma lesions were detected on chest thin-section standard-dose CT as well as pulmonary MR imaging with star vibe. Pulmonary parenchyma diseases were assessed on star vibe sequence and CT images, including masses (≥3 cm), nodules (<3 cm), consolidation, patchy shadow, cords focal, mesh shadow, ground glass density, mediastinal lymph nodes, pleural thickening, pleural effusion, emphysema, pulmonary bullae, traction bronchiectasis and so on. Chest CT images of each patient were reviewed by a chest radiologists with 25 years of experience, and the results were used as the reference standard for radiological findings. Then all images obtained with standard-dose CT and star vibe sequence were independently and double-blindly evaluated by two chest radiologists using a 5-point scoring criteria. The detection rate of star-vibe sequence for pulmonary parenchyma diseases was calculated.Results: The detection rates of pulmonary masses, consolidation, mediastinal lymph nodes and pleural effusion were 100% with STAR-VIBE sequence, the subjective scores of which were higher than 4-point and showed no significant difference between STAR-VIBE and CT (P>0.05). The MR imaging can detect pulmonary nodules and pleural thickening with a high rate about 94.2% and 92.9%, and the ground glass density, patchy shadow, mesh shadow, cords focal can also be displayed at a high rate with 80.1%, 85.2%, 85.7% and 88.0%, and the detection rates of traction bronchiectasis (66.7%) was higher than emphysema and bullae and lower than other pulmonary emphysema diseases, the subjective scores of which with STAR-VIBE were higher than 3-point. The pulmonary MR free-breathing T1-weighted 3D star vibe would miss all emphysema and bullae, and the subjective score were less than 2-point with STAR-VIBE.Conclusions: Pulmonary MR imaging with free-breathing T1- weighted 3D STAR-VIBE sequence is feasible for the assessment of pulmonary and mediastinal diseases and help to evaluate the radiological findings for patients with various pulmonary parenchyma diseases without radiation dose.
