Can we shorten the small-bowel capsule reading time with the “Quick-view” image detection system?

High sensitivity of quick view capsule endoscopy for detection of small bowel Crohn's disease

“…In agreement with other studies, we found that qv‐CE markedly reduces time consumption . The median time consumption for analyzing qv‐CE was 10 min, which is one fifth of the time reported by the last author in a previous study .…”

“…In a study of 81 patients with suspected or known CD, 155 and 71 ulcerations were detected with CE and qv‐CE (35% sampling rate), respectively, corresponding to a miss rate of 54% . Studies on mixed populations have reported lower miss rates, but isolated data for patients with suspected or known CD are not available …”

Optimizing lesion detection in small-bowel capsule endoscopy: from present problems to future solutions

“…QV is a computational tool, which scans all images and scores them according to the possible level of significance. Eventually, its output is CE images of potential interest to the CE reader, providing a fast pre-viewing option [99]. The number of images to be considered 'frames of interest' can be set as a percentage (e.g., 5, 10, 20, 80%, etc.)…”

A Rapid and Accurate Method to Detect Active Small Bowel Gastrointestinal Bleeding on Video Capsule Endoscopy

“…An additional algorithm contained in Rapid Reader 6.0, the suspected blood indicator (SBI), analyzes pixels to look for a red color that may be consistent with active or potential bleeding. There have been limited studies on the diagnostic efficacy of QV, and most results show that there may be an unacceptably high increase in diagnostic miss rate [5,6,8,9]. The published data regarding SBI is also limited, with one study showing an improved sensitivity and negative predictive value (83, 97 %) for active bleeding but lower specificity and positive predictive value (66, 23 %) [10].…”

“…For indications that may require urgent intervention based on results of the VCE, such as evaluation for GIB, prioritizing time to read a study in a timely manner may add a significant burden to a busy gastroenterologist. To improve the efficiency of reading VCE studies, several methods have been proposed including software that filters the number of images viewed and utilizing physician extenders (for example, nurses) to preliminarily review the study [4,[6][7][8][9]. The Rapid Reader 6.0 software program (Given imaging, Duluth, GA) contains two software algorithmic systems that allow for more rapid analysis of VCE studies.…”
