MRI Imaging: An Overview


Magnetic resonance imaging aka MRI imaging is a non-invasive technique employing a magnetic field and computer-generated radio waves. The process creates comprehensive, high-resolution images of the various components of your body, including tissues, organs and skeletal structures.

The Purpose of MRI Imaging

The images resulting from MRIs can be used by medical professionals to aid in diagnosing the presence of several possible medical problems. Those of the spinal cord, brain, heart, blood vessels and internal organs can help illuminate whether the following problems are present within the patient’s body:

  • Abnormalities on such body organs as the spleen, liver, uterus and kidney
  • Aneurysms in the brain
  • Brain injury resulting from trauma
  • Extent of the damage initiated by heart disease/attack
  • Function and size of the chambers of the heart
  • Multiple sclerosis
  • Spinal cord disorders
  • Stroke
  • Tumors on many of the body’s components including the brain, spinal cord, kidneys, ovaries and prostate

MRIs allow medical professionals to utilize the information they discover and analyze it to not only diagnose the problem but to put together a medical management plan.

Basic Types

There are many specific types of MRI imaging. However, in terms of construction, there are two basic types. These are:

  1. Traditional MRI Equipment: These are large, tube-shaped magnets in which a patient lies within.
  2. Open MRI Equipment: These represent the latest evolution in MRI technology. They are designed to address the concerns of those patients with weight problems as well as those who are claustrophobic. They are wider, less confined and more comfortable for those experiencing such issues.

Each has its advantages. Both provide the same crucial service and are essential tools in your doctor’s fight against debilitating and even life-ending medical issues.
