Balancing the need for data sharing to improve AI models with the obligation to safeguard patient privacy remains a major challenge in healthcare.

3. Data Quality and Availability

AI’s effectiveness is highly dependent on the quality, quantity, and consistency of the data it is trained on.

In radiology, this includes factors like image resolution, scan protocols, annotation quality, and completeness of records.

However, inconsistent imaging practices, outdated equipment, and missing or fragmented data across healthcare facilities can limit AI performance and reliability.

Without standardized data collection methods, it becomes difficult for AI systems to deliver generalizable and trustworthy results across diverse clinical environments.

4. Ethical and Regulatory Issues

The use of AI in radiology raises important ethical and legal questions.

Patients may not fully understand how their data is being used or how AI influences their care, leading to concerns about informed consent and transparency.

There is also ongoing debate over who is legally responsible when AI contributes to a misdiagnosis—the software developer, healthcare provider, or the institution.

Regulatory frameworks are still evolving, and the lack of standardized guidelines makes compliance difficult for innovators and clinicians alike.

Clear policies and ethical frameworks are necessary to support the safe and responsible implementation of AI.

5. Clinical Integration and Trust

Successfully implementing AI in radiology goes beyond technical performance—it requires clinical adoption and trust.

Radiologists may be hesitant to rely on AI if the system’s reasoning is opaque or difficult to interpret.

Additionally, they may fear AI taking over radiology, resulting in it actually replacing their role rather than assisting them.

To build trust, AI tools must be transparent, explainable, and designed to complement the expertise of medical professionals, not compete with it.

Training, education, and collaboration between developers and clinicians are key to ensuring that AI enhances rather than disrupts radiology workflows.
