Abstract
Artificial intelligence in medical imaging and diagnostic systems has transformed the landscape of healthcare delivery, enhancing precision, speed, and efficiency in disease detection. Over the past decade, the convergence of artificial intelligence, deep learning, and medical imaging modalities such as MRI, CT, PET, and ultrasound has facilitated automated diagnosis and predictive analytics. AI algorithms trained on large datasets are now capable of recognizing complex imaging patterns that often surpass human accuracy. This has proven vital in areas like oncology, neurology, cardiology, and radiology where early diagnosis significantly impacts patient outcomes. However, alongside its immense potential, the integration of AI in diagnostic systems presents challenges related to data privacy, algorithmic bias, regulatory compliance, and the interpretability of machine-generated results. Ethical concerns about accountability and transparency in decision-making have also become critical points of debate. The balance between opportunity and risk defines the future trajectory of AI in medical imaging. This paper explores both dimensions, focusing on how AI-driven innovations are reshaping diagnostic workflows while highlighting the pitfalls that may hinder clinical reliability. Keywords such as artificial intelligence, deep learning, computer vision, diagnostic accuracy, algorithmic bias, and healthcare ethics form the analytical backbone of this study. The paper also addresses how AI supports radiologists by augmenting rather than replacing their expertise and discusses the frameworks necessary to ensure safe, ethical, and equitable implementation across global health systems.
