The radiologic Evaluation of Mediastinal and Hilar Abnormality： tomography Using a Compensating Filter， and／or CT Following Pneumomediastinography

By conventional tomography using a compensating filter, and by these procedures and/or CT following pneumomediastinography in the evalution of heilar and mediastinal abnormality, it was confrimed that the well and lumen of trachea, main bronchus, tracheal bifurcation, upper lobe bronchus, a part of upper segmental bronchus and blood veaaels in hilar and mediastinal region were demonstrated clearly and in detail. Consequently, the mediastinal and hilar informations were evaluated more accurately : the lymph node involvement (swelling), the extension, orgination of mediastinal and hilar lesion and/or the presence and extent of adhesion or cancerous lesion.
