A COMPARISON OF COMPUTED TOMOGRAPHY, COMPUTED RADIOGRAPHY, AND FILM‐SCREEN RADIOGRAPHY FOR THE DETECTION OF CANINE PULMONARY NODULES

摘要: Computed tomography (CT) has become more widely available and computed radiography (CR) replaced film-screen for canine thoracic imaging in many veterinary practices. There are limited data comparing these modalities a clinical setting to detect pulmonary nodules. We compared CT, CR, detecting the presence, number, characteristics of nodules dogs. Observer performance variety experience levels was also evaluated. Twenty-one client-owned dogs with primary neoplastic process underwent CT CR; nine received radiographs. Positive/negative classification by consensus agreed between three 8/9 CR remaining 12. detected greatest (P = 0.002) total number no difference seen films. The right middle both caudal regions, but only using < 0.0001). Significantly smaller were 0.0007) minimum size accuracy high all modalities; particularly (90.5-100%) senior radiologist (90.5-100%). characterized least interobserver variability. Although performed similarly determining presence or absence nodules, greater associated diagnostic confidence observer agreement.
