WHY IMAGING? X-RAY How it works: Using a small amount of radiation, the X-ray unit takes pictures of the dense structures inside the body. What it's used for: Diagnosing broken bones, pneumonia and dental problems. Standard mammography uses X-ray to look at breast tissue. 30 W IN TER 2016 What to expect: You'll need to lie still on a table or stand in front of an imaging plate for a few seconds while the technician captures the image. "For classic, simple things, X-ray is very good and very low-cost," Fishman says. "It's good for certain things, like if you're worried about a fractured hip, a fractured wrist-a fractured anything- or pneumonia. The limitations are you can only see things that are dense, and it's a flat, 2-D image, so subtleties are very hard to see." CT SCAN How it works: Computed tomography (CT) scans use focused X-rays to create cross-section images of the body, allowing for clearer images as compared with simple X-rays. What it's used for: Diagnosing such issues as abdominal pain, blood clots, cancer, congenital heart defects, herniated disks, inflammatory bowel disease and internal bleeding. What to expect: You'll lie still on a table that will pass through a large circular machine that looks like a doughnut. It's not confining. You may need to hold your breath for a few seconds while the machine takes an image. Some tests require a contrast dye be consumed or injected beforehand to make parts of the body show up better on the images. "CTs are the big workhorses of medicine today," Fishman says. "You ULTRASOUND How it works: Ultrasound uses sound waves to create an image. No radiation is involved. What it's used for: In addition to its most notable use of looking at babies in utero, ultrasound also helps doctors diagnose conditions of the organs, including the heart, kidneys, liver, ovaries and thyroid. What to expect: This one is easy- you don't even need to worry about holding still. You'll lie on a table and, after applying some cold gel, a technician will run a wand over the area of the body being looked at to create multiple images. "Ultrasound uses sound waves, which allows you to look at fluid and soft tissue," Fishman says. "It doesn't have the detail of CT, but it's good for fluid density or when an area is surrounded by fat. It's most often used on the uterus, ovaries, gallbladder and thyroid gland, because they're close to the surface of the body." TOP IMAGES BY EXACTOSTOCK/GLOW IMAGES | SPREAD PHOTO BY NICK VEASEY/GETTY IMAGES Imaging tests are generally performed for one of three reasons: to screen for a common disease, to diagnose a condition or to determine the extent of a disease. They assist in assessing a wide range of issues from torn muscles and broken bones to aneurysms and cancer. They're invaluable tools of modern medicine that allow patients to avoid exploratory surgery and unnecessary treatments. But patients should be familiar with what exactly is being ordered and why. "It's important for patients to know why they're getting a test and ask questions," says Elliot K. Fishman, MD, a radiologist, an author and a member of the Radiological Society of North America. "Physicians shouldn't order a test just because we can. Ask your physician why one test is being ordered over another, and what exactly they're trying to find with the study." Next ask what you can expect during the imaging appointment and how you should prepare. Here are some basics to get you started: can look at it and accentuate a tissue, whether it's air, lungs, soft tissue, nose, muscle or bone, and also you can make 3-D imaging. It's very good for picking up abnormalities, especially pneumonia, tumors, cancer and aneurysms."
