[Examination of the fine interstitial changes of pneumoconiosis with high resolution computed tomography (HR-CT)]
Abstract:
High resolution CT was performed in 14 patients with fine interstitial changes of pneumoconiosis and Review image was evaluated for the diagnostic accuracy as compared with conventional chest roentgenogram. Of the 14 Patients in the study, 7 were divided category 1 by the ILO U/C classification, 4 were category 2, 3 were category 3. Studies of lung function showed obstructive ventilatory disturbance characterized by moderate reduction in FEV1.0% (58.6 +/- 16.5%) and V25/H (0.34 +/- 0.24 l/sec/m). HR-CT defined more sensitive in the presence of fine lung nodules than conventional X-p, and showed high contrast interfaces provided by the aerated lung. HR-CT was also of value in detecting bulla, bleb, peripleural changes and hilar lymphadenopathy. Radiologic-pathologic correlation was examined on the specimens of transbronchial lung biopsy in 4 patients, and revealed the diagnostic usefullness of HR-CT.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
