Hmmmm. You’ve been having some symptoms and you’re worried about what they might mean. After consulting with your physician, you’re scheduled for some diagnostic testing. But what do you know about the exam you’re having? And what will the experience be like? Here are some details.
X-Ray
An X-ray is one of the most commonly used diagnostic tests. It uses a small dose of radiation to provide images of your organs and other body parts. X-rays can be used to locate infections or tumors, detect fluid in the lungs, study blood vessels, and uncover many other medical conditions. Sometimes X-rays are used in conjunction with contrast agents, which can enhance the images.
For an X-ray, you’ll probably wear a hospital gown. Since this radiology test is noninvasive, there will be no pain, and it takes just a few minutes.
MRI
Magnetic resonance imaging (MRI) uses magnetic waves to produce two- and three-dimensional images of your body parts. This test can diagnose internal injuries and other conditions, and it can determine if treatment you’ve been prescribed is working.
For an MRI, you probably will not be allowed to eat for several hours before the test. The procedure is not painful, but some patients feel claustrophobic inside the MRI machine, which is like a long tunnel. Some facilities have open MRI, which many people find easier to tolerate. The test can take an hour or longer and you have to lie perfectly still, so you may be given a sedative before the test.
CT Scan
A computer tomography (CT) scan uses X-rays to take many cross-sectional views of the inside of your body. CT scans can produce clearer images of organs, tissue, bones, and other areas than traditional X-rays can. A CT scan can help a radiologist see a tumor, review skeletal problems, guide biopsies, and plan surgeries and treatments.
Before the test, you may have a contrast material injected into your vein. Then you will lie on your back on a movable table that slides through the CT scan machine. The procedure is painless and takes about 15 minutes.
Ultrasound
An ultrasound uses sound waves to look at the parts of your body. It is done in real time, so it is specifically good for studying the motion of fluid in your blood vessels. Ultrasounds are used for reviewing heart function, assessing plaque buildup, and for monitoring the development of a baby.
Depending on what the test is for, you may not be able to eat for several hours before the test. Or you may need to have a full bladder. During the exam, you will lie on a table, and your technician will spread gel over the body part being studied. Then he or she will move a transducer (a handheld wand) over that area, and images appear on a nearby screen. The procedure is painless and can take 20 or 30 minutes.
Mammography
A mammogram uses a low dose of radiation to screen for breast cancer. Most women age 40 and older are advised to get annual mammograms, but they can be used for women of all ages who are experiencing breast symptoms or have a high cancer risk.
For the test, you’ll have to take off your shirt and wear a front-opening medical gown or robe. You’ll be told not to wear perfume, antiperspirant, or powder, since they can appear as dots on your results. A mammogram requires two images of each breast, for a total of four images. For each image, you’ll have one breast placed on a platform and then compressed. Taking each image is very quick, but some women do experience discomfort. It’s smart to take deep breaths and try to relax.
Nuclear Medicine
Nuclear medicine uses small amounts of radioactive material to diagnose cancer, heart disease, and other problems within your body. For most nuclear medicine procedures, you’ll wear a medical gown and lie on a table. You may be given an IV. For some tests, you may need a catheter placed in your bladder, but otherwise, there should be no pain.
Before any diagnostic imaging tests, be sure to tell your doctor if you may be pregnant. Ask about any medications you may need to stop taking temporarily, and discuss any other preparation instructions.
