An MRI (Magnetic Resonance Imaging) is a procedure that will provide internal images of joints, soft tissue, structure, organs and much more. An MRI uses radio frequency waves and a magnet to create the images.
Because of the different sequences, you will hear various noises throughout the exam. ADI has the quietest scanners available and our experienced technologists pamper their patients with options such as music, warm blankets and cushions to make the experience as stress free as possible. At ADI, patients are in direct communication with the technologist through an intercom and a call alert button in case the patient needs assistance during the exam.
Let your doctor know if you are claustrophobic. Your physician can order sedation prior to your appointment at ADI.
An MRI can take up to one hour or longer. Sometimes an intravenous contrast is given to determine normal from abnormal tissue.
ADI’s MRI scanners provide the highest quality images available.

A CT scan is a low dose, faster kind of X-Ray imaging in which a thin x-ray beam rotates around the patient allowing doctors to see highly detailed images. ADI’s computer combines the images to form highly detailed three-dimensional pictures of the body. This type of imaging significantly helps the physician in determining a diagnosis.
The most common CT scans ordered will be of head, chest, abdomen, or pelvis. Sometimes multiple CT scans are done at the same time, (i.e. the chest and abdomen). Most times, an intravenous dye is given to help the doctors determine normal from abnormal findings. You will feel warm while the contrast is injected, but it only lasts for a minute.
If your doctor wants to scan your abdomen, you will have to drink a glass of oral contrast 1 hour prior and another glass 30 minutes prior to the scan. For CT scans with contrast, it is recommended that you do not eat or drink 4 to 6 hours before the scan (except for the contrast for the scan). A CT scan usually only takes 10 to 15 minutes once you are prepped for it.
How The Test Is Performed
You will be asked to lie on a table that slides into the center of the scanner.
How The Test Will Feel
The process is fairly painless. If contrast dye is to be administered, an IV will need to be placed in a small vein of a hand or arm or foot.
Why The Test Is Performed
CT provides rapid, detailed images of the patient that can then be reconstructed into three-dimensional images. Intravenous contrast improves evaluation of vessels and improves detection of tumors.
What The Risks Are
CT scans and other x-rays are monitored and regulated to provide the minimum amount of radiation exposure needed to produce the image. The risk associated with any individual scan is small. If IV contrast is injected, a risk of an allergic reaction in minimal. Statistics will be explained at time of testing.
Nuclear Medicine is a Radiology imaging procedure that is able to image the body on a functional level. Nuclear Medicine utilizes an injected tracer that gives off a small amount of radiation that allows the scanner to image the body. Different tracers are injected that allow the capture of different functions of the body. Typically, there are no side effects to the materials injected for a Nuclear Medicine procedure. The times and patient preparation for each test vary.
A bone scan is a test that checks for a variety of bone diseases, including cancer, stress fractures, fractures, and bone infection. A bone scan consists of an injection of a small amount of a radioactive substance similar to calcium that attaches to the bone. The tracer needs to circulate through the body for approximately 3 hours before the images are obtained. You are free to leave the imaging center during the 3 hours. The images will take about 45 minutes upon returning. There is no special preparation for a bone scan and we encourage ample hydration for the scan.
A Hida scan is an exam which allows for the determination of the functioning of the gallbladder. Typically an ultrasound can be done prior to a Hida scan. A Hida scan consists of an injection through an I.V. of a small amount of a radioactive tracer which allows the camera to see the process of the liver producing bile (which is what the gallbladder stores). It takes about 1 hour for this process to occur. Images will be performed during this time. Once the gallbladder is filled with bile, a second injection will be given of an enzyme which the body naturally produces. This is infused slowly over 15 minutes. Images are acquired for up to 45 minutes during the second part of this exam to image the gallbladder working. A computer program is then run to calculate how well the gallbladder is functioning. From start to finish, this exam will take about 2 hours. A DVD can be brought and watched during this exam. No food or drink for 6 hours prior to the exam.
Images how the kidneys are functioning. Can take up to 1 hour. No special preparation for this exam is needed.
This exam evaluates “hot” or “cold” thyroid nodules. Can take up to 1 hour. No special preparation for this exam is needed.
Gastric Emptying Scan
Determines how quickly the stomach empties food. Can take up to 2.5 hours. Nothing to eat or drink 6 hours prior to this exam.
Checks to see if there is a parathyroid adenoma. Can take up to 3.5 hours. No special preparation for this exam is needed.
WHAT IS PET/CT?
PET/CT combines two scanning techniques, PET and CT. The PET (positron emission tomography) shows different body functions while the CT (computed tomography) scan provides a detailed view of structural anatomy. The combined technology enables physicians to obtain highly-defined 3D images of the body.
WHY DO I NEED A PET/CT EXAM?
One of the best ways to fight disease is through early detection. PET/CT exams enable physicians to diagnose potential health issues and identify the best plan of treatment. A PET/CT scan may help reduce the need for additional biopsies or surgical procedures.
Prior to your exam, you will receive an injection of FDG (fluorodeoxyglucose), which is a harmless low-dose radiolabeled sugar. This is used to see how quickly the substance gets processed in your body. Diseased cells process the material more rapidly than the healthy tissue.
The PET scan captures the reaction and helps your physician identify the problem areas. When the functional images from PET are combined with the structural map from the coordinating CT scan, your physician can make an accurate diagnosis.
WHAT SHOULD I EXPECT DURING A PET/CT EXAM?
Our technologist or your physician will explain the details regarding your upcoming exam. In general, here is what can be expected:

HOW DO I PREPARE FOR THE EXAM?
Preparation and length of a PET/CT exam will depend on the type of scan your physician ordered. In general, please follow the guidelines below:
