This technique uses a powerful magnetic field and radiofrequency waves. No ionizing radiation is used. MRI is most useful to diagnose lesions that cannot be imaged with standard radiographs, ultrasound or computed tomography.
Radiologie Varad is proud to offer Gadovist, a macrocyclic and non-linear product to our clients for examinations with injection, therefore without depositing Gadolinium in the brain.
The scan uses X-rays that are emitted in a circular pattern around the patient and captured by detectors located on the opposite site of the emitter. From this information, the computer reconstructs images that represent the transverse slices of the body. The new machines are very fast and an exam can be performed in less than five minutes.
Ultrasound is a simple non-invasive examination, using an ultrasound beam to create an image by moving a probe on the skin surface. The Doppler technique allows for a more specific examination of blood vessels.
Ultrasound is used for abdominal and pelvic exploration, more specifically for the liver, kidneys, aorta, pancreas, gall bladder, uterus and ovaries. It is the preferred examination to monitor pregnancies. Ultrasound tests are also used to assess muscles, tendons, and other peri-articular structures.
Doppler exam evaluates blood flow; it can detect narrowing and occlusions of blood vessels. It is used for the carotid and vertebral arteries, the intracranial vessels, and the arteries and veins of the abdomen and extremities.
Mammography is a specialized examination of the breasts for the early detection of breast cancer and diseases of the breast. The exam is done with the use of specialized equipment especially designed for the breast.
This compression is needed for the following reasons:
It decreases the amount of radiation needed by decreasing the thickness of the breast;
It limits movement during the exposure;
It separates the breast tissue to allow better evaluation of lesions that could be hidden by the breast tissue;
It creates homogeneous thickness of the entire breast allowing a more uniform penetration of the tissue;
It increases the precision and detail of the breast by keeping the tissue closer to the film.
Two types of mammography:
Our mammographic technician takes all necessary precautions to minimize the pain that you may feel. If you did feel any pain during the compression, there is no cause for concern. This pain is temporary and without consequence.
Mammography is the most efficacious study to detect small breast cancers, but it does not detect all cancers. It is therefore important to practice regular breast self-examination. Post-menstrual is the best moment to identify breast changes. It is not easy to examine a breast but if you do it on a regular basis every month, after a year, you will have performed twelve examinations and you will know the feeling of your breasts and can then report any unusual changes there may be.
Our clinic is appointed by the Québec Breast Cancer Screening Program.
New generation Philips MicroDose mammograph, guaranteeing a rapid examination, with a lower radiation exposure and a great quality image.
Consultation, imaging and interventional procedures in musculoskeletal pathologies such as:
Retractile capsulitis of the shoulder
Calcifying tendinopathy of the shoulder or impingement syndrome of the shoulder
Our team of radiologists from the CHUM, specialized in musculoskeletal imaging and interventional radiology, will insure specialised treatments, in a comfortable environment, all the while favouring communication and a multidisciplinary approach with the referring physician.

Magnetic resonance imaging (MRI)
Ultrasound and ultrasound guided therapeutic injections
As you know, osteoporosis has become a more common medical problem with the aging population. Clinical research in this area is very active and has brought new therapeutic alternatives.
Over the recent years, there have been many new techniques to measure the bone density. Amoung the most commonly used exams; osteodensitometry is the study of choice. Its precision is superior to all other methods and allows easy follow-up of patients. The exposure to ionizing radiation is minimal and inferior to other methods. The exam is short in duration, around 5 minutes, and is comfortable for the patient.
The aims of the study are to:
Establish the indications for preventative hormone replacement at menopause;
Determine the bone density in patients who are at risk of developing severe osteoporosis;
Establish the diagnosis of osteoporosis when the radiograph raises a suspicion;
Follow the treatment response against osteoporosis.
