The field of radiology is constantly changing and evolving overtime. Technological advancements have rolled in ever since the conception of the MRI scanner. This imaging scanner has become a favorite of our radiologists along with our patients for its quality images and overall comfort. Let's take a look back in time to how MRI technology has changed overtime and how it continues to evolve.
Since the purpose of MRI's is to get quality images of the human body, it makes sense that over time those images have been getting better and better. The images are produced through the use of magnets and one major technology shift has been the movement from the 1.5T model to 3T model.
As seen in the names of the models, the 3T MRI machine has twice the magnetic field strength as the older 1.5T MRI machine. This increase in magnetic field strength transitively produces images that are twice as better. (In case you were wondering, these 3T machines cost a pretty penny more than the 1.5T models. 3T models can cost anywhere between $2-2.3 million compared to $1.5 million for the 1.5T models.)
In addition to the machine's magnetic strength, the shape and structure of MRI's have changed over the years too. Traditionally, only closed MRI's were used for medical imaging, but now there's been a shift to using open MRI's. This shift has had a huge impact on patient care because it is a much more accommodating option for patients (which is the #1 reason we use Open MRI's). There are multiple advantages to open MRI's, especially for patients who may be overweight, claustrophobic, antsy, or need additional support.
While MRI scanner were initially used for imaging purposes, this imaging scan can also be used for research. Scientists utilize MRI's to study how the body functions and as a way to answer important questions in science. Whether it's brain studies related to Alzheimer's Disease or research on how dogs feel emotions, MRI scanners have the capability of discovering new information.
MRI's are getting better and better each year due to technological advancements in the field. As technology improves, so will our patients comfort and scan experience. We will always offer the best imaging quality to our patients and continue to advance as technology improves overtime.
