Average Lifespan of the MRI

By Janae Leach

“Average MRI Scanner Nearing Adolescence.” Diagnostic Imaging. N.p., n.d. Web. 07 Nov.


This article provides information about the average lifespan of an MRI machine. According to the author, the average age of MRI scanners in the United States has risen to 11.4 years as of 2013. Surprisingly, most MRI owners are not planning on buying a new machine anytime. Researchers said that there was a spike of new MRI installations from 2002 to 2004, but there has not been a spike like that since. Overall, only 20 percent of all MRI users plan on purchasing a new system within the next three years. Even though newer machines are faster, can broaden clinical applications, and improve patient comfort, owners still refuse to purchase one. Many of them say that cost is the main reason for not buying new systems. The article also discusses the average growth rate of the MRI procedures, which is 2.8 percent per year. Most scans involve the spine, brain, prostate, and breast.

The article on the website possesses a more conversational tone. The author asks the reader a question at the beginning to help engage them in the article. The evidence is supported by scientific research and should, therefore, be considered a credible resource. The sentences flow together evenly and is easy to understand. It would have been a good idea, however, to expand on other reasons why MRI owners choose not to buy new machines besides cost.

Information regarding the lifespan of the MRI is good basic information to include in my essay. More background information provides a better understanding of the overall technology at hand. Also, the evidence of purchasers not buying new machines fits along with the public reaction section in my essay. They see that there are new options, which will mean better health care, yet they decide not to buy them due to the outrageous costs.
