Different types of brain imaging: MRI scanners utilize strong magnetic fields, magnetic field gradients, and radio waves to produce images of the internal organs in the body. MRA, a specialized form of MRI, focuses specifically on the body's blood vessels. CT scans, on the other hand, are a series of X-ray images transformed into cross-sectional images of the brain. PET scans involve the use of a radioactive tracer that binds to glucose in the bloodstream. As the brain primarily relies on glucose for fuel, the tracer accumulates in regions with high brain activity.

With so many technologies and use cases, getting started with artificial intelligence (AI) initiatives and deployments can be a daunting task for business leaders. It's important to understand the various categories of AI and the most suitable use cases for each type of technology. This helps to provide clarity and eliminate confusion between the various technologies and approaches involved. Dr. Marcell Vollmer, Chief Digital Officer, SAP Ariba, explains the major categories as: Categories of AI (Source: "How to make it simple to explain AI, ML, DL and Data Science?," Gaining clarity as to these different categories of AI and example use cases is an important first step.
