Welcome back to the Healthy Life Podcast...today we’re going to talk about the difference between a CT Scan, an MRI and an MRA. Trust me you need to understand the difference because many times tests are ordered because they can be and not that they will provide any benefit. I saw a post recently and felt that I could not easily respond to it in a few words so this is your crash course on radiography tests...
So what is the difference between an MRI’s MRA’s and CT Scan machines... well a CT scanner passes X-rays through the patient’s body as it moves through an arch, clicking various pictures through every angle.
As a result a CT scan can diagnose different levels of density and tissues inside a solid organ, and can also provide detailed information about the body, which includes the head, brain, eyes, inner ear, sinuses, chest, neck, shoulders, spine, pelvis, hips, reproductive systems, bladder and gastrointestinal tract.
Just to let you know an advanced CT scan focuses more on the patients comfort, shorter scanning times, and higher resolution images. MRI scans generally depend on powerful magnetic fields and radio frequency pulses for producing detailed pictures of organs, soft tissues, bone and other internal body structures. So an MRI image is capable of producing clearer pictures of normal and abnormal tissues.
A CT Scan is thought to be better than an MRI because:
MRI’S are thought better than CT scans for these reasons:
For immediate diagnosis of stroke the CT Scan is most helpful but long term diagnosis should use something called an MRA. An MRA, or magnetic resonance angiogram, is a type of MRI scan that uses MRI's magnetic fields and radio waves to produce pictures of blood vessels inside the body, allowing doctors to locate problems that may cause reduced blood flow. An MRI, or magnetic resonance imaging, is the technology behind an MRA, and it is used to examine soft ligament tissues and tendon injuries. Both scans are generally safe for most patients and do not expose them to ionizing radiation.
Because MRA scans look at the body's blood vessels, they are well suited to examining arteries in the brain, neck, chest, and abdomen and stomach. MRA scans are typically used for the following reasons:
I hope this helps you in understanding the difference between CT Scans, MRI’s and MRA’s. If you have questions you can talk with your doctor but hopefully this will give you a better foundation to have that discussion.
