[Radiologic-pathologic study on bronchial changes in peripheral solitary pulmonary lesions]

Area of Science:

• Thoracic Imageology
• Pulmonary Medicine
• Radiology

Background:

• Peripheral solitary pulmonary lesions pose diagnostic challenges.
• Bronchial changes are key morphological indicators, especially in peripheral lung cancer.
• Accurate evaluation of bronchial changes is crucial for diagnosis.

Purpose of the Study:

• To investigate the value of multi-slice CT (MSCT) in assessing bronchial changes.
• To correlate MSCT findings with postoperative pathology in patients with solitary pulmonary lesions.

Main Methods:

• Thirty patients with solitary pulmonary lesions underwent MSCT.
• Image data were reconstructed to visualize bronchial alterations.
• MSCT findings were compared with surgical pathology results.

Main Results:

• CT bronchial signs were universally positive.
• Bronchial wall thickening and cutoff on CT correlated with bronchial invasion in lung cancer patients.
• Absence of bronchial wall changes on CT sometimes indicated no invasion, but other findings like air bronchograms also showed varied pathological correlations.

Conclusions:

• MSCT effectively evaluates bronchial changes associated with peripheral solitary pulmonary lesions.
• This imaging modality shows promise in improving the diagnosis and differential diagnosis of these lesions.
