'''Artificial Intelligence in Healthcare''' refers to the integration of [[Artificial intelligence|artificial intelligence]] ([[AI]]) technologies into the [[healthcare]] sector to enhance the quality, accessibility, and efficiency of medical services. This interdisciplinary field combines expertise from [[computer science]], [[medicine]], [[biomedical engineering]], and other related areas to develop intelligent systems capable of analyzing complex medical data and supporting clinical decision-making.

== Applications ==
AI applications in healthcare are diverse and continually expanding. Key areas include:

=== Diagnostic Imaging ===
AI algorithms assist in the interpretation of medical images such as [[X-ray]], [[MRI]], and [[CT scan]], improving the accuracy and speed of diagnoses. For example, machine learning models can detect anomalies like tumors or fractures with high precision.<ref>{{Cite journal |last1=Esteva |first1=Andre |last2=Roberts |first2=Anna |title=AI in Healthcare: The Hope, the Hype, the Promise, the Peril |journal=Nature Medicine |year=2019 |volume=25 |issue=1 |pages=44–57 |doi=10.1038/s41591-018-0300-7}}</ref>

=== Predictive Analytics ===
AI-driven predictive models analyze patient data to forecast health trends, disease outbreaks, and individual patient outcomes. This capability enables proactive interventions and personalized treatment plans.<ref>{{Cite web |last=Topol |first=Eric |title=Deep Medicine: How Artificial Intelligence Can Make Healthcare Human Again |url=https://www.deeplearningbook.org |access-date=2023-10-01}}</ref>

=== Personalized Medicine ===
By leveraging genomic data and other personal health information, AI systems tailor treatments to individual patients, enhancing efficacy and reducing adverse effects.<ref>{{Cite book |last=Collins |first=Francis |title=The Language of Life: DNA and the Revolution in Personalized Medicine |year=2010 |publisher=Doubleday |isbn=978-0385523067}}</ref>

=== Virtual Health Assistants ===
AI-powered chatbots and virtual assistants provide patients with medical information, appointment scheduling, and preliminary diagnosis, thereby improving patient engagement and reducing the burden on healthcare providers.<ref>{{Cite journal |last=Bickmore |first=Tim W. |last2=Griffin |first2=Alice |title=Health Dialog Systems for Chronic Disease Management |journal=Journal of Biomedical Informatics |year=2019 |volume=95 |pages=103208 |doi=10.1016/j.jbi.2018.07.015}}</ref>
