Objective:To explore whether the phospholipidoproteinaceous material deposit within the alveoli by a high-ifeld 3T MRI has signal characters and its application for diagnosing pulmonary alveolar proteinosis.Methods:A total of 11 patients with pulmonary alveolar proteinosis previously diagnosed by ifberoptic bronchoscope lung biopsy underwent 64-slice helical CT scans and 3T MRI scans, and the CT scans and the MRI scans were compared.
Results:hTe phospholipidoproteinaceous material deposit within the alveoli presented longer or equal T1 relaxation time and longer T2 relaxation time, without characters of fatty or deposits of protein-like substance signals and enhancement. The distribution, form, number and size of the lesions at T2WI were almost the same as those at CT, the lesions were irregular in morphology, and there was a clear boundary between the lesions and the adjacent normal lung tissues. Dynamic contrast-enhanced MRI showed thickened pulmonary arteriolae and venulae in the lesions with more obviously thickened pulmonary venulae, which were in conformity with the pulmonary artery and venule enhancement. CT scan in 1 out of the 11 cases showed lesions in both lungs mainly consisted of stripe-shaped and reticular structures, and no obvious sign of pulmonary alveolar proteinosis residue was found. MRI scan detected alveolar proteinosis that failed to be shown by CT scan.
Conclusion:3T MRI T2WI can easily detect the lesions of long T2 signals formed by the lipoproteinaceous material deposit within the alveoli. In the lesions, geographic appearance was presented, and the crazy paving pattern was dimly visualized. MRI can relfect the morphological characters of PAP like CT and it is slightly better compared with CT in such aspects as evaluating the theraputic effect of lung lavage. As supplement to CT, high-field 3T MRI can serve as an important examination for lung diseases.

OBJECTIVE:
To explore characteristic CT findings and pathologic basis of ground glass opacity caused by pulmonary alveolar proteinosis (PAP).
METHODS:
Retrospective analysis of CT and pathological findings of 24 patients with PAP who were pathologically diagnosed from June 2006 to August 2011.
RESULTS:
Findings with CT: the lesions of the 24 patients mainly presented ground glass opacities. Local consolidations were seen in 8 patients. In 23 patients part of ground glass opacities bordered strip-shaped opacities with smooth edges, and there was a clear boundary between them and the bordering normal lung tissues, presenting a geographic appearance. Lesions in the 5 cases were mixed with alveoli or lobule aerocele, which made ground glass opacities present curved edges. Crazy paving pattern was detected in the 24 patients. Microscopically, the alveoli were seen to be filled with floccules proteinaceous material in various quantities in the 24 patients; hemangiectasis and congestion were seen in 17 patients, and enlarged alveolar cavities were seen in 5 patients.
CONCLUSION
PAP usually causes ground glass opacities with clear edges, and different from ground glass opacities with obscure edges caused by other pulmonary diseases. They are relatively specific to the imagining diagnosis to PAP.

OBJECTIVE:
To explore CT findings and pathologic basis of crazy paving pattern caused by pulmonary alveolar proteinosis.
METHODS:
Twenty-four patients who were diagnosed pathologically as pulmonary alveolar proteinosis by transbronchial lung biopsy and bronchoalveolar lavage fluid from June 2006 to May 2012 were included in this retrospective study. All patients underwent a 64-slice CT of the lungs.
RESULTS:
CT findings: crazy paving pattern was observed on CT imaging of all 24 patients. In 23 patients, crazy paving pattern displayed strip-shaped opacities with smooth edges, and there was a clear boundary between the pathological and normal lung tissues. The reticular opacities were connected with peripheral blood vessels and the branches were formed, and their diameters decreased slightly. Microscopically, hemangiectasis were seen in 17 patients.
CONCLUSION
Crazy paving pattern caused by pulmonary alveolar proteinosis displayed clear edges, and smooth reticular opacities, most of which were due to hemangiectasis of interlobular, interacinar and interalveolar septa. These findings of CT are helpful for the specific diagnosis of pulmonary alveolar proteinosis.
