Pulmonary high-resolution ultrashort TE MR imaging: Comparison with thin-section standard- and low-dose computed tomography for the assessment of pulmonary parenchyma diseases.

摘要: Background To determine the accuracy of pulmonary MR imaging with ultrashort echo time (UTE) for lung and mediastinum assessments using computed tomography (CT) as reference standard, various parenchyma diseases. Methods Eight-five consecutive patients (46 males: mean age, 69 years 39 females: years) diseases were examined chest standard- low-dose CTs UTE. This was followed by visual assessment a 5-point system presence nodules or masses, ground-glass opacity, micronodules, nodules, patchy shadow consolidation, emphysema bullae, bronchiectasis, reticular honeycomb traction bronchiectasis. Presence aneurysms, pleural pericardial effusions, thickening tumor, lymph adenopathy also evaluated system. To compare capability methods evaluation, intermethod agreement means kappa statistics χ2 test. Receiver operating characteristic analyses used to diagnostic performance all methods. Results Intermethod agreements between standard-dose CT significant either substantial almost perfect (0.67 ≤ κ ≤ 0.98; P < 0.0001). Areas under curve bronchiectasis opacity on significantly larger than those (emphysema bullae: P = 0.0002; opacity: P < 0.0001) P < 0.0001; bronchiectasis: P = 0.008; P < 0.0001). Conclusion Pulmonary UTE is useful evaluation radiological findings diseases. J. Magn. Reson. Imaging 2016;43:512–532.
