We can clearly see the intervertebral discs, spinal cord and nerve roots. We can visualize the tiny details of normal and abnormal human anatomy. Magnetic Resonance Imaging is an amazing tool that allows us to see deep inside the human body with a degree of clarity that is absolutely amazing. The resolution and clarity of the images is better, we can see more fine detail, and this test uses harmless radio waves instead of ionizing radiation. These images are superior to CT scans and X-rays. The axial plane creates a cross section of the human body.Īn MRI image looks like a photograph, but it is actually a computerized image of the nuclear magnetic resonance of molecules inside the human body. The saggital plane sections the human body lengthwise. The two most common slices that we look at on MRI scans of the spine are the sagittal and coronal slices. This technique allows us to visualize anatomic structures from any angle and direction. Magnetic Resonance Imaging creates thin section images of the inside of the human body. MRI scans slice the human body into thin sections Today, the modern practice of spine surgery relies heavily on the interpretation of MRI scans. Prior to this, we were basically making educated guesses about what was wrong with the spine.

The very first MRI scan of the human body was performed in 1977.
