Paper Abstract

This prospective study compared images obtained using a photo-stimulable imaging plate (IP) to images obtained using a conventional film/screen (FS) combination in a total of 66 patients, 26 of whom were undergoing surgical procedures requiring intra-operative arteriography and 40 of whom were undergoing cholangiography. Exposure factors, number of repeat examinations, and elapsed time for processing each image were recorded. Diagnostic accuracy of the two techniques was assessed objectively and image quality was assessed subjectively. The radiation dose was reduced by 50% using the IP technique. Due to the greater dynamic range of the IP system, no repeat IP examinations were required for either arteriography or cholangiography, while 6 (9%) of the FS studies had to be repeated due to under- or over-exposure. IP studies required very slightly more time for processing than FS studies, an average of 35 seconds per patient. Receiver operating characteristic (ROC) analysis revealed no significant difference in diagnostic accuracy between the two imaging techniques for either the arteriographic or cholangiographic studies. Subjective evaluation also revealed no significant difference in observer preference for IP vs FS studies.
