  In teleradiology, medical images are transmitted to offsite radiologists for
interpretation and the dictation report is sent back to the original site to
aid timely diagnosis and proper patient care. Although teleradiology offers
great benefits including time and cost efficiency, after-hour coverages, and
staffing shortage management, there are some technical and operational
limitations to overcome in reaching its full potential. We analyzed the current
teleradiology workflow to identify inefficiencies. Image unavailability and
delayed critical result communication stemmed from lack of system integration
between teleradiology practice and healthcare institutions are among the most
substantial factors causing prolonged turnaround time. In this paper, we
propose a blockchain-based medical image sharing and automated critical-results
notification platform to address the current limitation. We believe the
proposed platform will enhance efficiency in workflow by eliminating the need
for intermediaries and will benefit patients by eliminating the need for
storing medical images in hard copies. While considerable progress was
achieved, further research on governance and HIPAA compliance is required to
optimize the adoption of the new application. Towards an idea to a working
paradigm, we will implement the prototype during the next phase of our study.
