Artificial Intelligence in Radiology: A Narrative Review

Radiology undoubtedly plays a crucial role as the backbone of diagnostic imaging. It is one of the most sought-after specialities owing to a work-life balance and minimal patient interaction. The advent of Artificial Intelligence has undoubtedly proven to be a boon with online prescriptions, telemedicine, and advanced technology, revolutionising image-based diagnostic techniques. It is bound to bring tremendous changes in how one predicts the course of a disease, especially for those who rely on pattern recognition. The practice of radiology is set to undergo a seismic shift in the coming years, driven by the increasing application of machine learning and deep learning. It is high time to embrace these changes and remain up to date with recent developments, as virtual medical assistants powered by AI can give doctors the much-needed gift of time while improving the precision in diagnosis and management. This article summarizes the past foundations, present practice, and future opportunities of AI in radiology and the concepts essential to understand this integration. It also highlights the fact that careful implementation can ensure equity and efficiency in patient management.
