CT, CT scan, MRI, Open MRI, Radiology

Over the years we have heard every question pertaining to radiology and all the procedures in radiology. One of the biggest mistakes people make in radiology is knowing whether an MRI or a CT scan should be used. We’re firm believers that providing people with actual examples is one of the best ways to help them remember the differences between these two different procedures, so we’ve got a little test for you! If you need a refresher, learn about the differences between CT scans and MRI scans here. The answers to the questions are at the bottom of the post, try your best to pick on your own before peeking at them! Good luck!

Question 1: Which machine is a CT scanner and which is a MRI scanner?

Question 2: Bob was just in a car accident and has been rushed to the emergency room. They think he may have a few broken bones, and want to make sure nothing else is wrong internally. Should Bob get a CT scan or an MRI scan?

Question 3: Sally is a soccer player, and during her last game she injured something in her knee. Sally’s doctor thinks she may have torn a tendon or ligament. Should he order a CT scan or an MRI scan for Sally?


Question 1: The first picture is an MRI machine, the second picture is an CT machine.

Question 2: CT SCAN. CT machines are better at clearly showing injuries that affect bones and internal organs. Also, because CT scans take significantly less time than MRI’s do, in almost all emergency room cases they’re the preferred choice.

Question 3: MRI SCAN. MRI’s are great at showing differences between normal and abnormal tissue, and are particularly useful when the doctor is trying to examine tendons, ligaments, or the spinal chord due to their densities. So for an injury like Sally’s, an MRI is the best option.
