Abstract
Teleradiology is a way for transmitting radiological data in digital form. It enables
interactive connection between doctors and patients, providing long-distant
consultations. Data transmitted by teleradiology include medicine, radiology, static
images, moving images, complete medical records, etc. Teleradiology become a
global service with almost unlimited possibilities. The realization of this concept of
teleradiology includes choosing of appropriate hardware and software and the use of
recent radiological equipment. Teleradiology nowadays is the future of radiology
(Rade Babić et al., 2012).
Imaging informatics is a subspecialty of radiology that study of how information
about medical images is transmitted within radiology department and throughout the
hospital or outside it. For Effective use of PACS, radiologists should be familiar
with the basic technologic concepts behind workstation displays, computer
networking, data storage, and distribution of images. Any PACS will serve the
radiologist better if it is supplemented with software that is designed to meet
specific workflow needs (Branstetter BF. 2007).
PACSs are depends on digital communication, display, and information
technologies, which have revolutionized the practice of radiology, and the entire
clinical practice in medicine during the past decade (Brent J. Liu and H.K. Huang
2020).
To summarize the relative disadvantages of teleradiology are; costs of installing,
maintenance, technical points, legal aspects of a teleradiology system, medical
license and certified practitioners in different countries, training tele-radiologist is
required, and limited ways of communication with clinicians. To improve
teleradiology, many prefer to decrease teleradiology cost, train more Radiologists
and network experts on teleradiology systems, reduce the number of teleradiology
systems breakdowns, start accreditation programs for teleradiology globally,
provide more access for previous studies and patients’ histories, and allow more
communication between tele-radiologists and other clinicians for better
understanding. Teleradiology is a huge problem-solver, but many issues need to be
solved first to allow teleradiology higher impact on patients’ lives worldwide
(Alahmari 2019).
Teleradiology isn’t the only solution to the COVID-19 crisis, but it can be an
important step as it becomes more common throughout our health care systems (D.
Chopra 2020).
PACS & teleradiology is not the final target in advancement of medical imaging &
informatics field. The automated analysis of medical images has spread rapidly and
serving more in medical researchers. Radiologists are the most physicians to be
directly affected by advances in computer technology. Deep learning, big data ,
machine learning , Computer aided diagnosis & artificial intelgence are the next
targets beyond the advancement of PACS & Teleradiology.
The Ministries of Health, in many countries in the middle east such as KSA
according to the 2030 Vision, has placed teleradiology in its first Priorities
(Alshamrani K. M. et al, 2021).
In brief, the points of Weakness noticed in our study of Implementation of PACS
in Sohag University Hospital were:
Inability of auto sends of cases on PACS, so Auto routing is
recommended.
Inability of system to identify who’s see the cases , it can only explain
if the cases are seen or not
Number of reported cases on the PACS was non conclusive, as much
more cases were already reported but not on our PACS.
Number of verified cases on our PACS was much more non conclusive
indicator of the real utilization of our PACS.
Static IP service loss was equal to total loss of the system.
The strength points in our study of Implementation of PACS in Sohag University
Hospital were:
Long duration of the study (18 Months)
Continuous work of PACS system all over the duration of study
The study researcher himself (me) is the main admin of our PACS
Continuous contact with PACS maintenance team all over the duration of the
research.
PACS is connected & serving the majority of modalities in our department
(CR, CT & MRI)
Total number of sent cases on PACS during the research was conclusive (>
57000 case)
The economic value of using our PACS was conclusive (Saving > 1.5 million
EGP)
The recorded training sessions of using PACS by me, published on YouTube
for easier use & more acceptance of the system
Repeated updating of review of Literature according to the emerging
situations (as Covid 19 ) & explaining role of PACS in it
Server Redundancy was a real protective measure for PACS cases data up till
now.
The overall increased utilization of our PACS was the trend although of some
fluctuation as explained.
CONCLUSION
- Our study has concluded that PACS system in sohag university hospital give
an important services for radiology department, emergency cases, orthopedic
cases CR scans, and economic roles. Archiving of data for teaching & research
was other important implementation but these benefits are mainly depending on
good use and maintenance. PACS is the golden role of diagnostic aspects for
emergency cases. The total benefits of PACS are depending mainly on the
human factor in guiding, maintaining & improving its functions & components.
- Our study proved that PACS is saving time, lives, efforts & money.
Finally, our study conclude that PACS system has a great benefits as explained
and may be more but when human factor use & maintain it probably, while it can
lose most of its value, or completely destroyed if they did not consider this.
