Abstract
This was a radiologists' preference study to compare a digital chest radiog raphy system that utilizes a large-area silicon flat-panel detector with co nventional radiography for visualizing anatomic regions of the chest. Conve ntional and digital posteroanterior (PA) and lateral chest radiographs were obtained in 115 patients. The PA and lateral image pairs were compared ind ependently by three radiologists rating the overall appearance, 11 anatomic regions in the PA, and 9 in the lateral views. Statistical analysis was pe rformed with the Wilcoxon signed-rank test with Bonferroni-Holm adjustment (p = 0.05). For the PA view, the digital system performed significantly bet ter for the overall appearance and for all anatomic regions except for the peripheral pulmonary vasculature and hilum, where no significant difference was found. For the lateral digital images, the regions trachea, costodiaph ragmatic recess, and hilum were rated significantly worse. The regions retr osternal and retrocardiac lung were rated significantly better. The other r egions and the overall appearance showed no significant differences. The de scribed digital chest radiography system showed statistically superior visu alization of anatomic regions for PA and an ambiguous performance for later al images as compared with conventional radiography. After changing some im age processing parameters for the lateral view, this system may be suitable for digitalization of chest radiography.
