Purpose
The need for structured reporting in diagnostic radiology is becoming paramount
as electronic medical records evolve worldwide (1-3). However, attempts to develop
structured reporting solutions have not been widely adopted due to the tedious and timeconsuming nature of how a radiologist must interact with these systems (4-5).
We introduce a new multimedia structured reporting system, called ViSion, which allows
a radiologist to view and speak naturally about image findings while simultaneously
capturing structured data in order to generate a multimedia report that can be delivered in
multiple languages and used to support advanced applications such as disease tracking
(Figure 1) (6).

Methods and Materials
We developed a client-server software solution that allows a radiologist to record
key image findings from any picture archiving and communication system (PACS) or
advanced imaging workstation while he or she dictates descriptions of those findings.
The ViSion client software runs in parallel with any PACS or advanced imaging software
that operates on a computer workstation using the Windows® operating system (Figure
2).
Fig. 2: The ViSion system works by capturing key images from any PACS or
advanced imaging workstation, tagging the images with anatomy and pathology
terminology extracted from verbal dictations, and assembling a multimedia report on a
computer server that is accessible via a web browser.

As a radiologist identifies image findings, the he or she presses a speech microphone
or keyboard button to initiate a screen capture and record a verbal description of each
finding. The image and speech data are uploaded to a cloud-based server where
metadata describing the anatomical location, radiological observation/diagnosis, disease
metrics, medical priority, and target lesion designation are extracted from the transcribed
speech and used to tag the images in a database (Figure 3).
Fig. 3: A picture is worth 1000 words in whatever language is spoken, but ViSion tags
each key image with just two words describing a finding's anatomical location and
pathology (i.e., radiological observation or diagnosis).

Alternatively, a radiologist may use pull-down menus in the reporting system to tag
images. The data are then assembled into a multimedia structured report that organizes
the image findings by anatomical categories. Alternatively, ViSion can display the image
findings in a graphical representation of a patient with image icons linked to specific
anatomical sites. The assignment of a medical priority to each finding on a 5-point scale
Page 8 of 29
(from Incidental to Life-threatening) enables the automatic notification of critical results
when a ViSion report is signed by the radiologist.
The medical ontology (controlled vocabulary with defined relationships between terms)
used to support ViSion is described in another EPOS poster, "Development of the ViSion
Ontology." The basic principle of the ViSion ontology is that anatomy and pathology terms
are paired to create radiological observations and diagnoses (Figure 4).
Fig. 4: An observation or diagnosis in the ViSion system is created by the pairing of an
anatomy term with a pathology term. The ViSion ontology contains over 12,000 such
observations and diagnoses. Secondary characteristics can also be assigned in order
to provide additional detail for a particular finding. In this example, the terms "Colon"
+ "Polyp" are combined, and the secondary characteristics that may be assigned are
specific to colonic polyps.

The ViSion ontology contains over 12,000 observations and diagnoses that have been
translated to multiple languages. As a result, a ViSion report can be automatically

translated to any language covered by the system. ViSion does not translate the entire
narrative dictation associated with each finding but only the metadata which allows for
the communication of essential medical information (Figures 5-7).
Fig. 5: This is an example of a ViSion report generated in English. In addition to
the labeling of an image finding with anatomy and pathology terms, a finding may
be labeled with a priority level, disease metric, and target lesion designation. The
incorporation of the radiologist's verbal dictation, found under the audio column, allows
for the radiologist's unlimited freedom of expression.

ViSion provides the ability to link image findings from serial radiological examinations
in order to generate disease timelines illustrating progression of disease at specific
anatomical sites (Figure 8).

Particular image findings in a ViSion report can be designated by the radiologist as "target
lesions" from which ViSion automatically calculates response evaluation criteria in solid
tumors (RECIST) curves (Figure 9) (7).

that are used to calculate RECIST curves. Analysis of individual target lesions may

The concept of linking image findings may also be used to associate image data from
different medical disciplines, including pathology, histology, and genomics (Figure 10).

Fig. 10: The linking of image findings is not limited to radiological images but can be
applied to multiple image-based medical disciplines. In this example, a colonoscopy
image is linked to CT colonography, pathology, histology, and genomic images. Note
how the diagnosis changes from a non-specific entity "Mass" to "Adenocarcinoma" as a
more specific diagnosis is rendered.

Finally, ViSion is capable of creating a "composite" report that shows the most recent
image findings specific to anatomy, regardless of modality, so that the entire history of a
patient can be shown in a single display (Figure 11).

Results
ViSion provides a simple solution for structured reporting that can be used worldwide
and applied to multiple medical disciplines. ViSion's fundamental concept of linking
"image findings" supports many advanced applications including quantitative disease
assessment, electronic notification of critical results, and data mining of structured
radiologic information.
Conclusion
The adoption of structured reporting is essential to transforming radiology from a
qualitative to quantitative process. ViSion offers a unique solution for creating multimedia
structured reports with worldwide potential due to its ability to operate in multiple
languages and to support advanced applications that will add value to the radiologist's
role in the healthcare enterprise.
