title: Multiple-image in-room CT imaging guidance for interventional procedures.
abstract: This HIPAA-compliant study was approved by the institutional review board; informed consent was not required. The purpose of this study was to retrospectively compare room use time for interventional procedures performed with multiple-image multi-detector row computed tomographic (CT) fluoroscopy (n=196) and single-image spiral CT fluoroscopy (n=175). There was no statistically significant difference in age, sex, or procedural type between the two groups. The median room use time was 90 minutes (interquartile range, 65-120 minutes) for the single-image technique and 75 minutes (interquartile range, 60-105 minutes) for the multiple-image technique. A two-sample t test with equal variance assumption on the log-transformed data showed a statistically significant difference in log time (P<.001) between the two groups. This time savings could potentially have a substantial clinical effect on resource use and patient throughput.
