Evaluation of CT Scanning by Using Different Gantry Angles for Lung Nodules

Abstract

We developed a method of CT scanning with different gantry angles(tilted CT). Examining five patients with bronchogenic carcinoma, the tilted CT method seemed to be useful to show the relationship between nodules and vessel involvement, especially involved branched vessels. In addition, the tilted CT method more clearly showed the pleural indentation of interlobar fissures. The tilted CT method appears to be useful in evaluating pulmonary nodules as an additional technique to conventional CT scanning.
