The following Diagnostic Imaging Services are provided at each of the hospital sites in support of Inpatient, Emergency and Outpatients. A brief description of each of these services is outlined below:

Note: Milton District & Georgetown Hospitals have direct and equal access to services that may not available specifically at these sites.

Angiography/Interventional - OTMH

Angiography or arteriography is an imaging technique in which an X-ray image is taken to visualize the inside, or lumen, of blood vessels and organs of the body, with particular interest in the arteries, veins and the heart chambers.

Interventional studies are minimally invasive procedures that are performed using image guidance. Some of these procedures are done for diagnostic purposes, while others are done for treatment purposes. The images provide road maps that allow the Interventional Radiologist it guide instruments through the body to the areas of interest.

Bone Mineral Densitometry - OTMH, GH, MDH

Bone mineral densitometry (BMD) is an enhanced form of x-ray technology that is used to measure bone loss and to detect osteoporosis. It is a simple and painless procedure that allows your physician to assess the strength (or density) of your bones, to estimate your risk of fracture and to determine your response to treatment,

Computed Tomography - MDH & OTMH

CT scanning, sometimes called CAT scanning, is non-invasive medical test that helps physicians diagnose and treat medical conditions. CT imaging combines special x-ray equipment with sophisticated computers to produce multiple images or pictures of the inside of the body. These cross-sectional images of the area being studied can then be examined on a computer monitor or printed. CT scans of internal organs, bone, soft tissue and blood vessels provide greater clarity and reveal more details than regular x-ray exams.

General Imaging - OTMH, GH, MDH

An x-ray (radiograph) is a non-invasive medical test that helps physicians diagnose and treat medical conditions. Imaging with x-rays involves exposing a part of the body to a small dose of ionizing radiation to produce pictures of the inside of the body. X-rays are the oldest and most frequently used form of medical imaging.

Neurophysiology (EEG, EMG) - OTMH Only

Neurophysiology is the branch of neuroscience that studies the physiology of the nervous system. Within this area we perform electroencephalograms (EEG) which is a painless procedure that uses small, flat metal discs (electrodes) attached to the scalp, used to detect the electrical activity of the brain. Brain cells communicate via electrical impulses and are active all the time, this activity shows up as wavy lines on an EEG recording. An EEG is one of the main diagnostic tests for epilepsy and is utilized in diagnosing other brain disorders. In this area Electromyography (EMG) studies are also performed. This is a diagnostic procedure utilized to assess the health of muscles and the nerve cells that control them (motor neurons). Motor neurons transmit electrical signals that cause muscles to contract. An EMG translates these signals into graphs, sounds or numerical values that a specialist interprets.

Magnetic Resonance Imaging - OTMH Only

Magnetic resonance imaging (MRI) is a non-invasive medical test that helps physicians diagnose and treat medical conditions. MR imaging uses a powerful magnetic field, radio frequency pulses and a computer to produce detailed pictures of organs, soft tissues, bone and virtually all other internal body structures. The images can then be examined on a computer monitor, printed or copied to CD. MRI does not use ionizing radiation (x-rays). Detailed MR images allow physicians to better evaluate parts of the body and certain diseases that may not be assessed adequately with other imaging methods such as x-ray, ultrasound or computed tomography (also called CT or CAT scanning).

Mammography - OTMH, GH, MDH

Mammography is a specific type of imaging that uses a low-dose x-ray system to examine breasts. A mammography exam, called a mammogram, is used to aid in the early detection and diagnosis of breast diseases in women, typically through detection of characteristic masses and/or micro calcifications.

HHS Oakville and Milton Hospitals use Digital Radiography (DR). This means that the image is captured and is immediately electronically processed as a digital image. HHS Georgetown Hospital uses Screen Film technology, where the image is captured within a cassette using mammographic film. The film is then processed much like a film camera to make a negative.

Ontario Breast Screening Program - Georgetown Only

The Ontario Breast Screening Program (OBSP) is a comprehensive, organized breast cancer-screening program. Its mission is to reduce mortality from breast cancer by delivering high quality breast screening to Ontario women between the ages of 50 and 74, who have no previous history of breast cancer.

Service is provided through dedicated breast screening centers that must achieve accreditation with the Canadian Association of Radiologists Mammography Accreditation Program. The program is funded by the Ministry of Health and administered under Cancer Care Ontario.

Breast Cancer Scan

Nuclear Medicine - OTMH Only

Nuclear medicine is a branch of medical imaging that uses small amounts of radioactive material to diagnose or treat a variety of diseases, including many types of cancers, heart disease and certain other abnormalities within the body. Nuclear medicine or radionuclide imaging procedures are non-invasive and usually painless medical tests that help physicians diagnose medical conditions. These imaging scans use radioactive materials called radiopharmaceuticals or radiotracers. Nuclear medicine also offers therapeutic procedures such as radioactive iodine (I-131) therapy that uses radioactive material to treat cancer and other medical conditions affecting the thyroid gland.

Ultrasound - OTMH, MDH, GH

Ultrasound imaging, also called ultrasound scanning or sonography, involves exposing part of the body to high-frequency sound waves to produce pictures of the inside of the body. Ultrasound exams do not use ionizing radiation (as used in x-rays). Because ultrasound images are captured in real-time, they can show the structure and movement of the body's internal organs, as well as blood flowing through blood vessels. Ultrasound imaging is a non-invasive medical test that helps physicians diagnose and treat medical conditions.
