It is important to note that even though the open machine might appear to be less claustrophobic there is less space from the tip of the patient s nose to the top of the enclosure in an open machine than in a closed one. Open unit which is a large ring that patients pass through for the exam. Closed bore mris are one of the more traditional mri machines.

Magnetic resonance imaging mri is a medical imaging technique that uses a magnetic field and computer generated radio waves to create detailed images of the organs and tissues in your body. The quality of images from some open mri machines isn t as good as it is with a closed mri. Most mri machines are large tube shaped magnets.

What makes a closed bore mri different. The extended time spent in an enclosed mri unit often causes claustrophobia during scans. Mri does not use radiation as do x rays or ct scans. The small tube that a patient must lay in can cause a patient who is claustrophobic to panic.

This style of scanner almost always produces images that are of very high quality. This dye helps. They are less enclosed than a closed mri. They have an opening with a diameter around 50 60 centimeters most typically around 60 cm.

Some advantages of open vs. The following are pictures of a typical tunnel mri machine and an open mri machine. Closed mri closed mri machines. Patient comfort in these machines is sometimes a problem.
