Kidney Scan
The kidney scan uses radioisotopes to identify problems with the structure and function of the kidney. These scans are used after kidney transplants and to diagnose kidney failure, disorders, and infections.

In this test, the child lies on a table and a substance with a small amount of a radioisotope is injected into a vein. Then the kidneys are scanned, and images are sent to a computer. Results will be read by a radiologist and sent to the child’s doctor, who will present them to the parents.

Liver or Gallbladder Scan
The liver or gallbladder scan uses radioactive isotopes to look for liver or gallbladder damage: hepatitis, cirrhosis, abscess, infection, cancer, or injury. After a radioisotope is injected into a vein, it is absorbed by the liver or gallbladder. During the test, the child lies on a table under a scanner; the radioactive material is then picked up by a scanner, which transmits images to a computer. The radiologist interprets the findings and sends them to the child’s doctor, who will present them to the parents.

Lung Scan
A nuclear lung scan helps to determine the presence of a blood or abnormal formation of the lung. In this test, radioactive gas lung tracers are given by inhalation or injection so that the chest can be scanned. These scans can also be used to study malformations of the lung. The results will be read by a radiologist and sent to the child’s doctor, who will present them to the parents.

There are a wide variety of medical tests that can help diagnose diseases and conditions in children. These include scans (CT, MRI, nuclear), echocardiography, ultrasounds, X ray, and scans of bone, kidney, lung, thyroid, and urinary bladder.

CT Scan (Computed Tomography, or CAT scan)
CT scans provide many cross-sectional images of the body by using special X rays and computer enhancement to create an image that is much more sensitive than a simple X ray. After x-raying the body from many angles, the X rays are then analyzed by a computer to provide a picture of the body that can be viewed on a monitor or printed out as a photograph. The images show a composite slice of the body (usually the head, chest, or abdomen). In this procedure, a child lies flat on a movable table that moves into the center of the CT scanner.

As the child remains still, X rays are beamed into the body. If the child cannot remain still, sedatives are administered. Sometimes a dye or other contrast material is injected to better reveal blood vessels. Results are interpreted by radiologists and then reported to the child’s doctor, who will analyze and interpret them for the parents.

Echocardiography
This procedure uses a special device to detect the sound that is reflected from a beating heart. Sometimes called “diagnostic cardiac ultrasound,” this test uses reflected sound waves to show if a child has congenital heart defects, fluid around the heart, valve disorders, or weakened heart muscles. It is possible to actually see the heart move as the images are projected on a monitor. The direction of blood flow into and out of the heart can be seen in different colors on the monitor.

In this procedure, a child lies on his back, tilted slightly to the side. A special jelly is applied to the skin on the area of the heart, and the transducer is positioned over the heart. As sound waves are reflected back to the transducer, an image becomes visible on a monitor that can be turned into printouts from the screen. This test produces no radiation and the child experiences no discomfort. Although images are produced immediately, they must be interpreted by a cardiologist and sent to the child’s doctor, who will interpret them for the parents.
