Artificial intelligence: What is it?

Algorithms or computer programmes that use data to determine course of action or make predictions are referred to as artificial intelligence. In order for the computer to examine data and come to a judgment, scientists may develop a set of rules, or instructions, for the computer to follow.

For instance, Dr. Turkbey and his associates applied established guidelines for how prostate cancer shows up on an MRI scan. Then, they used tens of thousands of MRI scans to train their algorithm—some from men with prostate cancer and others from healthy men.

Machine learning is another artificial intelligence technique where the system trains itself how to evaluate and understand data.

AI study for cancer imaging

In order to determine if a mass is cancerous or not, doctors perform cancer imaging tests. How quickly is it developing if it is cancer? How much of a spread is it? Has it recovered since receiving treatment? According to studies, AI may enhance the promptness, precision, and dependability of medical professionals' responses.

To help with breast cancer screening tests and other types of cancer screening testing, scientists have created AI technologies. Over the past 20 years, AI-based computer algorithms have assisted doctors in deciphering mammograms, but the field of study is rapidly developing.

An AI system was developed by one team to assist in deciding how frequently women should be checked for breast cancer. The algorithm predicts a person's likelihood of acquiring breast cancer within the following five years based on the results of their mammograms. The model performed better in tests than the current breast cancer risk prediction methods.

Finding cancer

AI has the ability to help diagnose cancer earlier in people who are already exhibiting signs. For instance, the AI model created by Dr. Turkbey and his colleagues at the NCI's Center for Cancer Research may make it simpler for radiologists to identify prostate cancer that may be aggressive on a relatively new type of prostate MRI scan known as multiparametric MRI.
