Nuclear Medicine
Nuclear Medicine at ZP
Our nuclear medicine department combines the latest advances in technology with highly trained nuclear medicine physicians, radiologists, cardiologists, nurses, and nuclear technologists. We have a long-standing reputation for excellence in diagnostic nuclear imaging on Long Island, and offer this test in both Nassau and Suffolk counties.
At ZP, we offer Single Photon Emission Computed Tomography (SPECT) imaging, which uses specialized cameras to visualize the internal organs at work, as well as the body's anatomy through three-dimensional images.
How it Works
During a nuclear medicine scan, a small amount of radioactive material or radiopharmaceutical is introduced into your body either intravenously or orally and gets absorbed by the cells. A specially developed camera records images and measures the accumulation of the radiopharmaceutical in the patient’s body. Higher metabolic activity can correspond to areas of disease or “hot spots” in the study. For some studies, the activity of the radiopharmaceutical can indicate how well an organ is functioning.
Nuclear medicine can be used to detect and evaluate a number of disorders including tumors, irregular or inadequate blood flow, and inadequate functioning of organs like the thyroid, heart, lungs, gallbladder, liver, and kidneys.
During the Test
For most exams, the radiopharmaceutical will be administered through an I.V. but some exams do require it to be taken orally. The radiotracer must circulate through your body for a certain amount of time, depending on the type of study. This can take anywhere from half an hour to several hours. The radiopharmaceutical is absorbed by both normal and abnormal tissue, according to their metabolic rate.
You will then be brought into the exam room and asked to lie down on the scanning table. A specialized nuclear medicine camera will slowly move over the area of your body being scanned. Be sure to remain as still as possible to ensure the best possible images. Depending on the specific study, your scan may take from 30 minutes up to two hours.
Once all of the images have been recorded, the nuclear camera will move away and the technologist will return to assist you off the table.
Nuclear Medicine is Used in Many Scans Including:
Bone Scans
Heart Scans
Brain Scans
Breast Scans
Different Types of Nuclear Medicine Exams
A MUGA scan (Multiple Gated Acquisition scan) is a noninvasive test used to evaluate cardiac function. The MUGA scan produces a moving image of the beating heart, and from this image, several important features can be determined about the health of the left and right ventricles (the heart’s major pumping chambers). A MUGA scan is particularly good at giving a reading of the overall pumping ability of the heart.
A nuclear bone scan uses a radioactive tracer and high-resolution camera to identify areas of new bone growth or areas in which bone has broken down. In general, bone scans are an excellent tool for identifying and evaluating damage to bones, assessing infections and trauma, and detecting cancer that has metastasized to the bones.
How to prepare
The specific test that you are having will determine the preparation required. Be sure to review the instructions given by the ZP representative, as well as your doctor, when scheduling your appointment. Some procedures require that you fast, while others require no special preparation at all.
Please call 631-444-5544, ext. 4886 to schedule and receive your preparations.
After the Test
Increase your fluid intake for the next 24 hours to help flush the radiopharmaceutical out of your system. Depending on the type of exam, you may be required to stop breastfeeding or limit your contact with pregnant women, small children, and pets.
