MRI

MRI uses a powerful magnetic field, radio frequency pulses and a computer to produce detailed pictures of organs, soft tissues, bone and nearly all other internal body structures.

At Perry County Memorial Hospital (PCMH), we offer the most advanced MRI technology clinically available. PCMH is the first critical access hospital in the state of Missouri and in the Southeast region to offer a 3 Tesla MRI.

Here's an overview of the benefits of the 3 Tesla MRI machine:

  • Superb quality. The 3 Tesla MRI boasts the strongest magnet field strength used today. The higher the strength, the more clarity and detail is provided in the image, helping physicians in diagnosis. 
  • A wide range of uses. It can be used for many applications, including neurology, "functional neurology", orthopedic cartilage assessment; and breast, vascular, and cardiac imaging.
  • Comfort. With one foot of headroom, you won't feel like you are nose to nose with the top of the magnet. We also have an iPod docking station and music system. Feel free to bring in your iPod, iPhone, or favorite CD so you can listen to your own music during your exam.
  • Speed. Our MRI uses Total Imaging Matrix (TIM™) technology to scan multiple areas of the body at one time, which means the test is over faster than a traditional MRI.

The MRI Difference

We often boast that we offer the most advanced MRI technology clinically available, and we feel we have every reason to. However, we want you to see what all the excitement is about as well as show you exactly why you should have an MRI completed by us. Our studies offer physicians the most detailed view of your body so they can accurately diagnose and treat your conditions. Just see for yourself!

Key technical differences

Local Competitor: Slice thickness is 4mm with a 4.5mm gap between images.
PCMH: Slice thickness is 1mm with a .2mm gap between images.

Slice thickness is important for detail and structure resolution, i.e. so the doctor can clearly see the anatomy that he or she is looking at. Thinner slices provide greater detail, but require a larger, more efficient magnet (what PCMH has). Less efficient scanners have to image at larger slice thicknesses to help produce an image with fewer artifacts and in a reasonable time period. Also, a larger gap between images is required to avoid image-image artifact. The trade-off of a larger slice (what the competitor produces) is less detail. The trade-off of a larger slice gap is missed anatomy as well. You can clearly see the difference in the anatomy and clarity PCMH's MRI provides the doctors versus the local competitor's.

Local Competitor: Slice thickness is 3mm with a 4.0mm gap between images.
PCMH: Slice thickness is 2mm with a .2mm gap between images.

In the PCMH image above, notice the uniform saturation of all tissues across the image. Both muscle and fat are equally gray providing image optimization. On the competitor's image, the fat is very dark and muscle is a very light gray.

Also, notice the edge detail differences of the articular cartilage being pointed out by the arrows. PCMH's image is a lot sharper.

On the PCMH image above, make sure to direct your attention to the arrow. The individual fibers of the anterior cruciate ligament are in clear detail when an MRI is performed with PCMH's 3T MRI.

Local Competitor: Slice thickness is 3.5mm with a 4.0mm gap between images.
PCMH: Slice thickness is 3mm with a .3mm gap between images.

This particular image sequence is in general a signal starved sequence. What that means is that in order to produce great images with fine detail in this sequence you must image nearly twice as long or have a larger magnet with more effficient scan processes, which the second option is available at PCMH.

PCMH: Slice thickness is 2mm with a .2mm gap between images.

You can clearly see the difference in detail provided between the two images of the individual fibers of the anterior cruciate ligament (ACL) as well as the articular cartilage detail. PCMH's image definitely provides a sharper picture.

Preparing for an MRI

If you have a pacemaker, you CANNOT have an MRI.

The only patient preps for MRI's are those listed below:

  • Magnetic Resonance Angiography (MRA): Drink four to six glasses of clear liquids the day before the exam.
  • Magnetic Resonance Cholangiopancreatography (MRCP): Do not eat or drink anything after midnight. If scanning is to be performed the same day as the test is ordered, do not have anything to eat or drink for at least four hours before the exam.
