title: Xerotomography of peripheral lung lesions.
abstract: Xerotomography was compared to conventional tomography in 72 patients with peripheral lung lesions. The xerotomogram was superior to the conventional tomogram in 41 patients, and yielded no additional information in 31. Details of lesions were better displayed, especially the margins: cavitations, air bronchogram and bronchiectasis, and calcification. Differentiation between benign, inflammatory and malignant lesions was facilitated. The xerotomographic process improved the image detail of lesions due to the edge enhancement property and the greater recording latitude of contrast of the xeroradiographs. Xerotomography is recommended only in selected patients for a few tomographic cuts because of the high radiation dosage.
