Diagnostic Imaging

Soldiers’ diagnostics departments take the time to ensure all levels of quality, safety and service are met or exceeded for all our patients

Diagnostic Imaging

Please refer to our Visiting Soldiers’ page for screening requirements and safety protocols.

The recently renovated Diagnostic Imaging Department is proud to offer a full range of diagnostic procedures to Orillia and the surrounding area.

We are focused on providing high quality service in a safe patient environment. Any concerns you may have about your exam you are encouraged to ask.

We are the second Magnetic Resonance Imaging (MRI) machine in the North Simcoe Muskoka area and have contributed to reducing the wait times in our area significantly to help allow our patients to receive a quicker diagnosis. OSMH has also invested in and installed a Picture Archiving and Communication System (PACS) which has eliminated the use of traditional x-ray film.

All patient images are now stored electronically and viewed on computer. This process has helped to reduce report turnaround times, increased availability of all studies to the physician and makes it easier to take studies to medical consultations. The PACS system at OSMH is shared with Muskoka Algonquin Healthcare and Georgian Bay General Hospital.

Computed Tomography (CT) Scan

Spiral Computed Tomography or CT, is an x-ray imaging technology that uses computer manipulation to produce three-dimensional construction pictures as well as multi-plane studies of a patient’s anatomy. This service is used for diagnostic examinations as well as for emergency examinations, based on consultation between the referring physician and radiologist.

Nuclear Medicine

This service involves state-of-the-art digital equipment featuring a Varicam photographic system that scans continuously while orbiting the body. Complete scans can be done in as little as 17 minutes. Varicam technology is used to diagnose circulatory problems, cardiac disease, bone, kidney, heart and lung problems, as well as cancer. It can also enhance diagnostic procedures for diseases such as breast cancer.

Bone Densitometry

The 15 minute bone densitometry test is used to find out if a patient has, or will develop, osteoporosis. Images are usually taken of the lower back and hip area. A baseline test is normally done around the time of menopause and may be repeated every two years.

Ultrasound uses high-frequency sound waves to examine internal soft tissue in patients. Tests are done on internal abdominal or pelvic organs, and more superficial structures such as veins, arteries and thyroid glands.

Magnetic Resonance Imaging (MRI)

An MRI is a procedure that uses magnetic fields instead of radiation to take detailed pictures of tissues and organs in the body. It is especially useful to see fine tissue contrast, internal organs and structures in great detail from different angles. An MRI is often done to diagnose brain and nervous system problems; bone, joint and muscle disorders; tumours; certain heart and blood vessel disease; or cancer of the reproductive organs, liver, kidneys, lymph nodes, bladder, pancreas or vocal cords. Depending on what is being examined, the MRI scan can last anywhere from 20 minutes and up.

Interventional Radiology (IR)

Interventional Radiology is an ever-evolving field within Diagnostic Imaging and is relatively new to OSMH (since 2017). IR is a procedures-based service that uses image guidance to perform surgical interventions on an out-patient and in-patient basis. See below for a compiled list of procedures and patient documents, as well as the IR requisition.

Cardio-Respiratory Diagnostics

Cardio-Respiratory diagnostics offers a variety of testing based on the individual needs from a physician referral.  Testing offered at OSMH includes:

Acute Cardiac Evaluation Services (ACES)

Acute cardiac evaluation service is a rapid access clinic for urgent cardiac diagnostic testing and consultation with internal medicine. Referrals are received from both the emergency department as well as family physicians. Patients will be seen as soon as possible, usually within a 48 hour period.

Cardiac Stress Test

A stress test, sometimes called a treadmill test or exercise test, helps a doctor find out how well your heart responds to exertion. The patient is attached to an ECG monitor while they walk on a treadmill. Their heart rate, rhythm and blood pressure are monitored by the cardio technologist.

Myocardial Perfusion Studies

Also referred to as Nuclear stress testing may be indicated when there are contraindications to a regular exercise stress test or when a doctor requires more information from the stress test.

  • Cardiolite
    In addition to a regular stress test the patient will have an I.V inserted where the nuclear technologist can inject a nuclear tracer at peak exercise. The nuclear tracer will allow the doctor to see areas of the heart that may be suggestive of coronary artery disease. You will be required to return for secondary (resting) imaging on another day given to you by the nuclear technologist.

  • Persantine
    A nuclear imaging study for patients who are unable to effectively perform a regular stress test. You will be given an IV where the physician will administer a medication that will simulate exercise in the body followed by an injection of the nuclear tracer. You will be required to return for secondary (resting) imaging on another day given to you by the nuclear technologist.

Holter Monitor

A Holter monitor is a battery-operated portable device that measures and records your heart’s electrical activity. The doctor may order this test to learn more from your heart during everyday situations.  The test can be 24/48/72 hours or 7/14 days.


An electrocardiogram is a non-invasive test that checks the function of your heart by measuring its electrical activity. Ten electrodes are attached to the patient’s chest, arms and legs to record heart rate and rhythm.

Ambulatory Blood Pressure Monitoring (ABPM)

ABPM is a battery-operated portable device that measures and records your blood pressure over 24 hours.  This exam is not covered by OHIP which carries a $75 fee payable to OSMH, please refer to http://osmh.on.ca/paymybill for instruction.  Fees can be submitted to your personal benefits plan for reimbursement.

Pulmonary Function Testing

Pulmonary function tests (PFTs) are noninvasive tests that show how well the lungs are working. The tests measure lung volume, capacity, rates of flow, and gas exchange. This information can help your healthcare provider diagnose and decide the treatment of certain lung disorders.
