Questions about MRIsWhat are the differences?

Closed Bore - Open MRI Wide Bore

Closed BoreClose Bore MRI are usually high field systems that have excellent image quality, speed and a magnet strength ranging from 1.0T to 3.0TThe “bore” or area where the patient is scanned has the smallest opening, around 60CM.This can make many patients feel claustrophobic and many larger patients simply cannot fit.

Open MRIOpen MRI is open on three to four sides.

It allows larger framed or claustrophobic patients to be scanned comfortably.

Magnet size starts at .35T to .7T and tops out around 1.2T.  The result is reduced image quality when compared to Closed Bore MRI.

Best used on extremities (knee, shoulder). It takes roughly one and a half to two times longer to produce a comparable image.

Wide Bore MRIWide Bore MRI is also referred to as Open Bore. It combines the benefits of Closed Bore with more space inside the bore area.

It delivers high magnet strength, high quality imaging and shorter procedure time than an Open MRI. It is ideal for larger and claustrophobic patients because of the 70cm opening.

This MRI provides an economic benefit because patient preparation time is reduced & image quality is high.

Comparing the Strength of an MRI

Let’s say:A .35T Magnet is a Nissan Maxima

A 1.5T Magnet is a Audi A5

A 3T Magnet is a Maserati

The Audi A5 and Nissan Maxima are similar to each other but the Audi has more features, a better reputation and more advantages.

The Maserati is clearly in a league of its own but not practical for all purposes: • Can’t fit more then 2 people• Can’t carry luggage• Sits to Low to ground• Goes so fast you might get a

ticket

Today the 1.5T is considered the standard MRI in a clinical setting. 1.5T is ideal for abdomens and chests scans where a patient is asked to hold their breath since it is faster than lower strength MRI machines. There is more signal with a 1.5T magnet so you can run shorter times and have higher image quality.

High field no longer means better images while Open technology continues to improve. You can achieve great images by setting up proper parameters and protocols based on the MRI you chose.
