Have you considered what could happen if a hospital’s diagnostic images are tampered with, locked out of the system, or exposed in some way due to cybercriminal activity? In 2024, the average cost of a healthcare data breach was $10.93 million per event, resulting in healthcare being the most costly industry for cyberattacks.
This is no longer a hypothetical risk. Medical image systems are now interconnected throughout hospital networks. Many have cloud-based solutions that increase both the efficiency with which they operate and their risk exposure.
Organizations need to employ stronger cybersecurity design. This article will highlight why securing medical imaging has become critical in today’s healthcare environment.
The Evolving Role of Medical Imaging
Medical imaging is no longer restricted to one area. Medical imaging scans are present throughout radiology departments, specialist offices, electronic health records, and, sometimes, even in clinician offices.
Medical imaging has evolved so much that digital imaging technologies that include MRI, computed tomography (CT), digital radiography (X-ray), ultrasound, and cardiovascular imaging apparatus are all connected to each other. This creates a connected healthcare system that improves communication and collaboration between different areas. Because this system now has many access points, the risk of medical imaging data being disclosed or compromised through cyberspace has also increased.
Medical Imaging Systems Place Networks At Risk
Medical images are more than just photographs of patients. They represent medical history information related to the patient’s identity, diagnostic tests performed on them, and all treatment decisions made for the patient. For this reason, cyber criminals view medical images as being highly desirable.
One issue associated with imaging systems is their exposure to hospital networks. In order for imaging systems to perform correctly, they need to communicate with many hospital departments through a complex computer network.
If imaging systems are not segregated properly in the hospital computer network, the risks related to network intrusions increase significantly. Another factor that makes imaging systems susceptible to cyber attacks is their age. Many imaging systems use older computer programs that cannot easily be updated without disrupting normal operations in clinical settings.
Security Considerations of Cloud-Based Imaging
With the continued shift towards digital transformation in healthcare, a large number of hospitals are transferring their imaging systems to cloud-based solutions. They allow for greater efficiencies in accessing patient images, the ability to collaborate between specialists, and the ability to scale storage for large imaging data sets.
Cloud computing adds additional burdens on the hospital as they must provide additional security safeguards for data. For example, hospitals need to make sure there are security protections for the imaging data and that the data has been encrypted both while at rest and in transit.
It will also be important for hospitals to have security measures in place to authenticate authorized users prior to granting access. They should also be able to continuously monitor for any suspicious activities occurring on those systems.
When properly secured, centralized security systems can be used to provide greater security since security protection is provided in a central location rather than using several disparate local systems. A centralized system can provide continuous access control and auditing through the cloud.
The Importance of Data Integrity for Cardiac Imaging Workflows within Connected Healthcare
Cardiac imaging is one of the most data-intensive areas of diagnostic medicine. Clinicians use echocardiography and other cardiovascular imaging technologies to assess heart structure, blood flow, and cardiac function in real time, often sharing results instantly with cardiology teams across multiple healthcare systems.
Because these imaging workflows directly influence diagnoses, treatment planning, and ongoing patient monitoring, maintaining imaging accuracy and secure data transmission is critical. This is one reason cardiac sonography in patient care plays such an important role within connected healthcare environments where imaging systems, cloud platforms, and hospital networks continuously exchange sensitive diagnostic information.
A breach, delay, or corruption involving cardiac imaging data can negatively affect clinical decision-making and potentially compromise patient outcomes during time-sensitive treatment situations.
Human Behavior and Security Gaps
Most advanced systems can experience weakened security as a direct result of human behavior. In busy clinical settings, there are many healthcare workers who tend to be so intensely absorbed in their diagnostic tasks that they may not have time to follow security protocols when working.
Hyperfixation behavior patterns, characterized by deep focus on a task, reduce awareness of surrounding risks. It can be a major security issue with healthcare workers. A common example of this is where an Imaging Specialist can skip a step of authentication and proceed to share data too quickly, exposing sensitive data due to forgetfulness or error.
A potential way to remedy this situation is by creating systems where fewer barriers to performing a task exist, developing security training to raise awareness, and implementing automated systems to decrease reliance on manual compliance in high-pressure environments.
The Future of Imaging Security
The future use of medical imaging technology continues to advance toward more sophisticated, intelligent, and proactive imaging systems using Artificial Intelligence to detect unusual patterns of access in real time. The use of zero-trust security models will ensure that there is always a verification requirement for every device and user.
No device or user will automatically be considered trustable based solely on their being on a hospital network. Some hospitals are looking into using blockchain-based verification systems to ensure imaging data cannot be modified without detection.
Why Imaging Security Can No Longer Be Ignored
Medical imaging is foundational to modern healthcare delivery. However, the increased ability to connect devices and share data leaves medical imaging as a highly targeted area for cyber crime.
Hospitals or healthcare organizations that design patient-centric workflows will be positioned to optimally secure their patient data and ultimately improve their clinical outcomes. Securing medical imaging systems is a clinical necessity and should be considered a support mechanism for accurate diagnosis, safe treatment, and establishing patient trust.
