can help radiologists to find teaching

Text mining algorithms are employed
to determine the frequency of critical
radiology results and identify those containing documentation of communication using automated text classification
algorithms, and to assess the impact of a
policy requiring documentation of critical results communication. 44 The texture
analysis software allows users to perform
texture analyses on any type of medical
image without the need for image transfer by simply placing a region of interest.
This tool has already been used to assess
the trabecular network of vertebra. The
integration of such software into PACS
extends the applicability of texture analysis beyond that of a mere research tool
and facilitates its use in routine clinical
Data mining and NLP techniques
provide quick access to a vast repository
of images and radiology reports with
both high precision and recall values
and extract key images from radiology
reports fetched from PACS. Such systems could be helpful in order to find
diagnoses, improve report quality, and
save time using semantic text analysis
by terminology of a radiological lexicon.
Consequently, the system has become
a valuable tool in daily clinical routine,
education, and research. 46 Automated
data mining of nuclear medicine reports
and automated anatomy specific CT
radiation exposure extraction are other
applications of BI tools for quality assurance and organ dose monitoring which
enhances patient safety. 47
On the other hand, dashboards are
efficient tools for improving the radiology department’s operations and in
maintaining high quality standards.
In a study, a web-based dashboard was
constructed to automate the extraction,
processing, and display of indicators and
thereby provide useful and current data
for management. 48
Repeats are indicators to improve service and quality. Through a digital x-ray
dashboard, dose management, x-ray
usage, and repeat analysis data can be
made available. Therefore, this system can
be an opportunity for more precise and
frequent key parameter monitoring and
intervention. 49 In another study, a PACS
integrated digital dashboard designed to
alert radiologists to their unsigned report
queue status, coupled with an actionable link to the report signing application, resulted in a reduction in the time
between transcription and report finalization. The dashboard was well received
by radiologists who reported high usage
for signing reports. 50 Also, a PACS integrated digital dashboard can help address
deficiencies and facilitate informed, optimized workflow decisions. 51
Hospitals are organizations rich in intel-
lectual assets. Using these assets is in
line with improving performance to
reach strategic goals and objectives and
becoming an innovative organization.
It is necessary to have technologies that
can eliminate information asymmetry
and utilize all assets so that a correctly
informed hospital would be able to:
• Respond to environmental changes
• Identify new market opportunities
• Become a learning organization by dis-
covering new patterns and relationship
• Achieve best practices by analyzing
patterns of treatment and results and
also comparing them with standards in
order to improve quality of care and
• Achieve the highest efficiency and
lowest costs and identify abuses and
frauds by matching costs with deliv-
BI provides an opportunity for hos-
pitals to look at many aspects of the
business, such as operations, finance,
quality, and public health and identify
factors that are affecting performance.
In order to achieve success in the devel-
opment of BI systems, there needs to be
an organizational culture supporting
analysts, designers, and users who have
the required skills for identifying, mod-
eling, and sharing knowledge. The right
architecture needs to be in place and
the required information from all user-
groups needs to be harnessed efficiently.
Clear business objectives for the BI solu-
tion need to be established.
