Artificial intelligence is rapidly transforming clinical diagnostics, but its adoption has outpaced the safeguards needed to ensure safe and equitable use. This has led to documented failures—including misdiagnoses, biased outcomes, and uncritical reliance by clinicians—driven by gaps in validation, governance, and professional training. The core issue is not the technology itself, but the conditions under which it is deployed, particularly the lack of accountability, oversight, and integration into clinical decision-making standards. Addressing these risks requires stronger regulation, clearer responsibility, and a shift toward rigorous validation and AI literacy in healthcare.
