Magnetic Resonance Imaging (MRI)

What is a Magnetic Resonance Imaging (MRI)?

MRI, or magnetic resonance imaging, is a means of “seeing” inside of the body in order for doctors to find certain diseases or abnormal conditions. MRI does not rely on the type of radiation (i.e. ionizing radiation) used for an x-ray or computed tomography (CT). The MRI examination requires specialized equipment that uses a very powerful, constant magnetic field, rapidly changing local magnetic fields, radiofrequency energy, and dedicated equipment including a powerful computer to create very clear pictures of internal body structures.

During the MRI examination, the patient is placed within the MR system or “scanner”. The powerful, constant magnetic field aligns a tiny fraction of subatomic particles called protons that are present in most of the body’s tissues. Radiofrequency energy is applied to cause these protons to produce signals that are picked up by a receiver within the scanner. The signals are specially characterized using the rapidly changing, local magnetic field and computer-processed to produce images of the body part of interest.

How can I book an appointment for an MRI?

An MRI scan has been ordered by your Primary Care Provider (PCP). The reason for the MRI scan will come from them and any questions you may have should be referred to them. To help you prepare for your scan, LACGH MRI has listed the steps which should assist you in making this a seamless exam.

When the MRI Booking Office receives your completed requisition from your PCP, you will be called and asked a series of questions pertaining to your past medical history and surgeries. This relates to safety for your MRI. This is very important since MRI uses a very strong magnet to produce your images. Once this screening process is completed and there are no further documents required, you will be given an appointment date and time. Also, if there are any specific instructions that pertain to your MRI scan, they will be given to you at this time. If no instructions are given, then please arrive at the appointment time given.
