Artificial intelligence (AI) has emerged as one of the most transformative innovations in modern medicine. What once seemed like science fiction has evolved into a reality that is revolutionizing how diseases are diagnosed, treated, and managed. However, the integration of AI in healthcare didn't happen overnight. It is the result of decades of research, investment, and technological development, leading to significant breakthroughs, especially in medical imaging diagnostics and surgery.

The origins of AI can be traced back to the 1950s when pioneers like Alan Turing proposed the possibility of creating machines capable of simulating human thought. However, the first attempts to use AI in medicine began to take shape only in the 1970s and 1980s with expert systems like MYCIN, developed at Stanford University to diagnose bacterial infections. This pioneering system could suggest antibiotic treatments based on clinical data provided by physicians. Though it was never implemented in real clinical use, MYCIN paved the way for the idea that machines could provide diagnostic assistance.

Throughout the 1990s and 2000s, the increase in computing power and the availability of vast amounts of data allowed AI to make significant strides forward. In healthcare, the ability to process large datasets led to the development of more sophisticated algorithms. However, it is only in the last decade that AI has begun to deeply integrate into the medical sector, with two fields benefiting most from its advancements: medical imaging diagnostics and robotic surgery.

Medical imaging diagnostics is arguably one of the most emblematic areas of AI application in medicine. The analysis of radiological images, such as CT scans, MRIs, and mammograms, requires a detailed review that can sometimes escape even the trained eye of a radiologist. This is where AI has made its strongest impact. In 2017, the U.S. Food and Drug Administration (FDA) approved the first AI algorithm for breast cancer diagnosis using digital mammograms. Developed by IBM Watson Health, this system was among the first to demonstrate how AI could enhance diagnostic accuracy and reduce false positives, enabling more timely and accurate diagnoses.

Another notable example is Google Health's AI algorithm for diagnosing diabetic retinopathy. The algorithm, tested on large datasets of retinal images, was able to detect early signs of the disease with accuracy comparable to that of top ophthalmologists. This technology, now used in clinics in India, has the potential to save the sight of millions in developing countries, where access to specialists is limited.

The operating room is another field where AI is making giant leaps. Robotic surgery, once limited to machines guided by human surgeons—like the Da Vinci Surgical System—is rapidly evolving toward a phase where machines can actively assist in intraoperative decision-making. In 2016, a research team at Johns Hopkins University demonstrated that an AI-powered surgical robot, dubbed the “Smart Tissue Autonomous Robot” (STAR), was able to perform sutures on soft tissue with greater precision than human surgeons. This milestone demonstrated that AI is not merely an assistant but could become a central actor in performing delicate operations.

Another significant impact of AI in surgery is its use in preoperative planning. Advanced algorithms analyze medical images to create personalized 3D models of a patient’s body. This allows surgeons to plan procedures with greater precision, reducing risks and improving postoperative outcomes. Specifically, systems like "Zebra Medical Vision" use AI to analyze radiological images and identify abnormalities with astonishing accuracy, helping surgeons prepare for operations.

Today, the numbers are impressive. According to a 2023 report from MIT Technology Review, he use of AI in imaging diagnostics has reduced scan analysis times by up to 50%, while improving diagnostic accuracy by 20%. In the United States, over 300 hospitals are using AI systems for the early detection of diseases such as lung cancer, with many of these systems becoming indispensable tools for physicians.

Despite its successes, the integration of AI in medicine is not without challenges. Issues related to data privacy, regulation, and legal liability remain to be fully resolved. However, what is clear is that AI is no longer just a promise for the future. It is already a clinical reality, with tangible impacts on patients' lives.
