MRI's require a strong magnetic field around your body. Making a strong magnetic field requires a large magnet. In some cases, the technology has gotten better and there are "open MRI" machines where what can be made smaller has been, and you no longer travel through a tunnel to get scanned.

The Short Answer

MRI's require a strong magnetic field around your body. Making a strong magnetic field requires a large magnet. In some cases, the technology has gotten better and there are "open MRI" machines where what can be made smaller has been, and you no longer travel through a tunnel to get scanned. At the very least though the machine must be able to generate a magnetic field around whatever is being scanned (such as your body).
