CT colonography (CTC) is a colorectal cancer screening and diagnostic technique that comprises basic 4 steps: (1) bowel preparation,
(2) gas insufflation,
(3) CT or MRI scanning,
and (4) 2D and 3D image analysis (Figure 1).
Standardized reporting of CTC exams is essential for the effective communication of diagnostic results,
tracking of patient outcomes,
and support of national data registries such as the American College of Radiology's (ACR) CTC Data Registry. Although various imaging...
Methods and materials
We developed a multimedia structured reporting system,
which operates in parallel with any vendor’s CTC image processing and display software running on a computer workstation using a Microsoft operating system (1).
ViSion comprises a client-server software system that enables a radiologist to capture key images from a CTC imaging system and tag those images with metadata describing the anatomical location and radiological observation/diagnosis of the finding (Figure 2). As a...
We applied the ViSion structured reporting system to 100 CTC cases performed at our institution to create standardized CTC reports which were subsequently uploaded into the ACR’s CTC Data Registry (3).
Since the ACR data registry currently lacks an application programming interface (API),
these data were manually transferred from ViSion reports into the registry forms (Figure 15).
Whenever the ACR develops an API,
we will modify the ViSion software so that it can automatically upload ViSion...
The practice of radiology is undergoing a transition from narrative reporting to structured reporting.
We have developed a structured reporting system that can be used to standardize the reporting of CTC examinations,
support international disease registries,
and conduct data mining for outcomes analyses.
