MRI, CT, and PET: Decoding Diagnostic Imaging Alphabet Soup
 

Which of the following are types of diagnostic imaging exams? CT, PET, LRQ, MRI, or IGP? It’s hard to know for sure, isn’t it? And even if you do know, what are all of these exams and when should your doctor order them?

 

Why Everyone Should Know How to Decode the Diagnostic Soup

 

Being acquainted with the various types of diagnostic imaging is an important part of taking charge of your own health. Diagnostic imaging refers to a variety of methods by which your doctor can examine what is happening inside your body and actually see your organs functioning without performing surgery. Your doctor orders the best exam for your medical situation. But you and your doctor are a team in your health care and, when you are informed, you can help your doctor ensure that the care you are receiving is what is best for you.

 

Your Diagnostic Decoder

 

The first type of diagnostic imaging was in the form of x-rays. For more than one hundred years, x-rays have allowed doctors to see what is happening inside a patient’s body. X-rays let them see bones, joints, and organs like the heart and lungs that they would otherwise only be able to see through surgery.

 

Today, in addition to x-rays, there is a seemingly endless list of diagnostic imaging exams. It helps to be familiar with each of them and what they are used for so you can work with your doctor to ensure the exam that is ordered is the best exam for you:

 

Angiography

 

Angiography is used to see problems in organs like your heart and your brain.

 

CT (or “CAT”) Scan

 

A CT (or “CAT”) scan allows your doctor to see specific areas of your body from angles she would be unable to achieve with a regular x-ray. A CT is also more specific than an x-ray, creating images that are like thin “slices” of your body.

 

Cardiac Catheterization

 

A cardiac catheterization is a type of x-ray exam that shows your doctor how your heart works for a period of time. It is like a short movie of your heart that allows your doctor to see if anything is wrong.

 

Fluoroscopy

 

Fluoroscopy is like a cardiac catheterization, but can be used to see various organs in the body.

 

Mammogram

 

Mammograms provide doctors with information about something that might not be normal inside a patient’s breast. Most doctors recommend that women forty and older receive a mammogram each year to detect early signs of breast cancer or other problems.

 

MRI

 

An MRI is used to examine the heart, joints, lungs, and brain. It is also used to detect cancer and to help plan cancer treatment.

 

PET

 

PET scans have a number of uses, but they are most often used to check for cancer and to check on cancer treatments.

 

Ultrasound

 

Ultrasound is often used to look at a baby before it’s born. Ultrasound also allows your doctor to see organs like your heart, liver, kidney, and bladder.

 

Now That You’ve Broken the Code

 

Understanding what the various types of imaging exams are and why they are used can help put you at ease when your doctor orders one for you. It’s comforting to have some knowledge of what is happening to your body. This knowledge can also help you begin a dialogue with your doctor about her plan for your health care.
