Medical imaging services (listed alphabetically):


Bone densitometry

Bone mineral densitometry is a safe and painless test utilizing very low exposure to radiation. The test measures bone density and the mineral content of bone in a person's body. Bone densitometry is used for the prevention, diagnosis and treatment of osteoporosis.

Computed tomography (CT)

A CT (computed tomography) scan is an X-ray procedure that combines many X-ray images with the aid of a computer to generate cross-sectional views and, if needed, three-dimensional images of the internal organs and structures of the body. CT scans define normal and abnormal structures in the body. At times, intravenously injected iodine-containing contrast material is used. A CT scan is painless and can provide extremely accurate images of body structures in addition to guiding the radiologist in performing certain procedures, such as biopsies of suspected cancers, removal of internal body fluids for various tests, and the draining of abscesses which are deep in the body. Many of these procedures are minimally invasive and have markedly decreased the need to perform surgery to accomplish the same outcome.

Patients with a history of allergy to iodine or X-ray dye should notify their physicians and radiology staff. Oral contrast may also be required for CT abdomen and CT pelvis examinations.

Fluoroscopy

Fluoroscopy uses X-rays to produce continuous imaging (video) of structures inside the body. Fluoroscopy is commonly used to image the different systems within the body, e.g., the stomach, shoulder, urinary tract, etc.

General r
adiography (X-ray)

General X-rays are images/pictures (in digital format) of structures inside the body using radiation. Common exams include chest, abdomen, wrist, ankle, etc. Appointments are not scheduled for General Radiography. Please proceed to the General site with your requisition and health card during the hours indicated.

Interventional radiology

Interventional radiology is a subspecialty in Medical Imaging in which minimally invasive procedures are performed with image guidance. Some of these procedures are done for diagnostic purposes ( e.g. angiograms and biopsies); others are done for treatment purposes (e.g. uterine fibroid embolizations and fluid drainages). Our interventional radiologists use equipment like X-rays, Ultrasound, CT or MRI to guide small needles and catheters through small insertions in the skin into blood vessels or tissue. These needles and catheters are advanced to areas containing disease or other abnormality.

Interventional radiology procedures often replace open surgical procedures and most can be performed on an outpatient basis or only require a short hospital stay. They are better tolerated by the patient since they do not involve large incisions. There is less risk than surgery, the patient experiences less pain and the recovery time is shorter.

Magnetic resonance imaging (MRI)

Magnetic Resonance Imaging (MRI) is a diagnostic technique that produces computerized images of internal body tissue and is based on magnetic vibration of tiny molecules within the body induced by the application of radio waves. With no known side effects, MRI provides cross-sectional images of muscles, nerves, ligaments, tendons, spinal cord, brain, heart and breast.


Hours and contact information

Mammography

Mammography is the process of using low-dose X-rays to image breast tissue, with the focus on early detection of breast cancer. Mammography services at North York General Hospital are offered at the Branson Ambulatory Care Centre. As well, women with suspicious breast abnormalities receive comprehensive services, including mammography, in the BMO Financial Group Breast Diagnostic Centre (BDC), part of the Karen, Heather and Lynn Steinberg Breast Services, located at the General site*.The hospital is an accredited site of the Ontario Breast Screening Program.

At North York General, we provide digital mammography, which is a specialized form of mammography using digital receptors and computers instead of X-ray film. Our digital equipment also offers tomosynthesis capability which creates a 3-dimensional picture of the breast. We are proud to be the first site in Ontario utilizing tomosynthesis diagnostically.

Ontario Breast Screening Program (OBSP)

The North York General Hospital Branson Ambulatory Care Centre OBSP site is accredited by the Canadian Association of Radiologists - Mammography Accreditation Program. Benefits of the Ontario Breast Screening Program:
• Women aged 50 or older with no previous history may schedule their own appointment.
Reminder letters are sent out for your next appointment.
Breast screening can find cancer early. Finding breast cancer early saves lives.

Nuclear cardiology

Nuclear cardiology is the study of the heart using small amounts of radioactive tracers. It allows us to study the function of the heart non-invasively (without inserting any instruments into the heart itself). The most commonly used test in nuclear cardiology is called myocardial perfusion imaging. It is a diagnostic tool that is often used for the detection of coronary artery disease (narrowing of the heart arteries). Myocardial perfusion imaging is a form of stress test which makes use of myocardial perfusion tracers and gamma camera imaging methods to assess the adequacy of blood flow to the heart, as well as to assess how much of the heart muscle is viable (alive) and how much is scarred and damaged beyond repair after a heart attack.

Nuclear medicine

Nuclear medicine imaging procedures often identify abnormalities very early in the progress of a disease, long before many medical problems are apparent with other diagnostic tests. Nuclear medicine uses very small amounts of radioactive materials (radiopharmaceuticals) to diagnose and treat disease. In imaging, the radiopharmaceuticals are detected by special types of cameras that work with computers to provide very precise pictures about the area of the body being imaged. In treatment, the radiopharmaceuticals go directly to the organ being treated.

The amount of radiation in a typical nuclear imaging procedure is comparable with that received during a diagnostic X-ray, and the amount received in a typical treatment procedure is kept within safe limits.

Nuclear medicine imaging is unique, because it provides doctors with information about both structure and function. It is a way to gather medical information that would otherwise be unavailable, require surgery, or necessitate more expensive diagnostic tests.

General site: Monday to Friday, 8:30 a.m. to 4:30 p.m.

Ultrasound

An ultrasound scan (also called sonography) is a diagnostic medical examination that uses high-frequency sound waves to produce images of organs, tissues or blood flow inside the body. The high-frequency sound waves are transmitted to the area of interest and the returning echoes are recorded. Ultrasound is non-invasive and involves no radiation. Diagnostic ultrasound can be used to examine many parts of the body, such as the abdomen, breasts, female reproductive system including obstetrical ultrasound, the prostate, the heart, blood vessels and more. In addition, diagnostic ultrasound is utilized during image guided biopsies and selected interventional procedure.
