My Health Centre (Formerly Parkway Nuclear Services)

My Health Centre (formerly Parkway Nuclear Services) is located at Ross Memorial Hospital on the 3rd Floor and can be reached at 705-328-6171.

Hours of Operation

Nuclear medicine is the use of safe, radioactive materials to help diagnose and treat a wide variety of diseases and disorders.

My Health Centre performs a number of tests, including bone scans, bone density tests, liver/spleen scans, lung scans, heart scans, and thyroid uptake. Scans provide information about the anatomy of the body and the function of its organs.

When you undergo a nuclear medicine scan, a chemical compound, which contains a small amount of radioactive substance, is administered either by injection in the vein, by mouth through a breathing device or by some other method to place it in the body. After the administration of the compound, you may be asked to wait a period of time (a few hours or even days) before the actual scanning begins. The waiting period is necessary because the compounds take different amounts of time to accumulate in the area of your body being studied.

During the scan, a camera will be placed close to the part of your body being studied. A number of different images will be taken, which will later be interpreted by the nuclear medicine physician. All testing is safe, painless and commonly performed.

Bone Scans

Bone scans require only one injection, which is injected into a vein and travels through the blood to the skeletal system. The scan is performed a few hours after the injection and takes approximately 30-45 minutes. Your bone scan will often be compared with x-rays in order to obtain the maximum information possible.

Liver Scans

One type of scan is the liver/spleen scan, which is performed shortly after the compound is injected into a vein. Generally, the entire test takes 30-45 minutes.

Another type of liver scan is the biliary scan, which demonstrates the function of the liver and the gallbladder. This scan is most commonly used to diagnose abnormal functions of the gallbladder due to acute inflammation. This procedure usually takes one to two hours.

Lung Scans

Lung scans are usually used to show blood flow (a perfusion scan) and the movement of air (ventilation scan) both into and out of the lungs. These are used to see if there are blood clots (pulmonary emboli) in the lungs. Perfusion scans are performed immediately after the injection of the compound. Ventilation lung scans are performed by breathing in a tasteless, odorless radioactive gas or aerosol through a mouthpiece. This will show where there may be any obstructions or whether there may be other types of breathing abnormalities. Both of these scans usually take 15-30 minutes.

Heart Scans

There are several types of heart scans, which show different aspects of heart function and structure. The type of scan you undergo is determined by the specific information your physician is seeking. The most common heart scans identify normal and abnormal blood flow to the heart muscle, measure how well the heart pumps muscle blood or determines the existence or extent of damage to your heart muscle from a recent occurrence, such as a heart attack.

Thyroid Uptake and Scan

The thyroid uptake test determines the overall function of your thyroid gland. This test is performed with a probe that is placed in front of your neck, which measures the amount of activity in the thyroid gland. The thyroid scan provides a picture of the gland to determine which areas are functioning better than others, and to identify and locate abnormalities, such as lumps or inflammation. Both tests take approximately 30 minutes.

Other Scans

Other nuclear medicine scans include: gallium scans to evaluate infection and certain types of tumors; kidney scans to evaluate infection, obstruction, trauma or high blood pressure; brain scans; gastrointestinal bleeding scans; flow studies of arteries and veins; and scrotal scans; among others.
