Attention! Screening mammography is not done at Westmount Square Medical Imaging. We cannot accept a requisition for mammography on which the expressions "dépistage" or "screening" are either circled, checked or written. Instead, please order either a "routine" or a "diagnostic" mammogram.
Please advise your patients which had previous mammograms in another clinic that they must bring their mammographic films the day of their exams.
Depending on the age of your patients and circumstances, an ultrasound might be recommended instead of a mammography. Below are the rules at WSMI:
|30 yrs or less||For mass or pain||No||Yes|
|31-35 yrs||Routine - no family history||No||Yes|
|31-35 yrs||Routine - with family history||Yes|
|31-35 yrs||For mass or pain||No||Yes|
|36-40 yrs||Routine - with family history||Yes|
|36-40 yrs||Routine -no family history||No||Yes|
|36-40 yrs||For mass or pain||Yes|
|41 and over||Routine - no family history||Yes|
|41 and over||Routine - with family history||Yes|
|41 and over||For mass or pain||Yes|
The request for spot compression or magnification views might be needed to conclude the study and will be determined by the radiologist at WSMI following the review of the initial mammography. Spot compression exams should be done in the same clinic as the initial exam. If this is the case, the personnel of WSMI will communicate with your patient in order to arrange an appointment for additional mammographic images.
In order to comply with the RAMQ rules, your patient cannot undergo more than 1 bone densitometry every 366 days. Exception to this rule are allowed in case your patient has specific conditions such as high dose of steroid, biphosphonates, renal transplant, dialysis or is neuro-polytraumatic), in this case you can order a bone densitometry every 6 months for the first 18 months of the treatment.
Also, unless it is to assess a trauma or a fracture, RAMQ does not cover thoracic, lumbar, pelvic or hip X-rays a week before or within a month after the bone densitometry is undergone by your patient.
It is contraindicated to undergo barium examinations (such as Upper GI, Barium Enema, and Virtual Colonoscopy), a PET scan or Nuclear Medicine examinations less than a week before your bone density exam.
It is also recommended that your patients don't take calcium supplements the day of their exams.
WSMI offers a complete range of barium examinations such as Barium Swallow (oesophagus), Barium Meal or Upper G.I. (stomach), Small Bowel Follow Through (small intestine) and Barium Enema (colon).
Only the Barium Swallow (done alone) does not require the patient to prepare. It is very important for the quality of these examinations that your patients follow the preparation specific to our clinic.
Patient's Preparation - Upper G.I.
Patient's Preparation - SBFT
Patient's Preparation - Barium Enema
In the case of a CT scan with contrast-agent injection (iodine), you must provide us with the creatinine level (blood report) of your patient done within the last three (for cancer patients) or six months (all others). Since we need this level before your patient obtains an appointment it is important to send it with your exam requisition.
Depending on the type of CT scan your patient will be undergoing, a preparation might be required. Generally, the preparation for contrast-agent injection examination is of 3 hours of complete fasting. Your patients will be advised upon the coordination of their appointment.
If your patient is diabetic, they must stop taking Glucophage or Metformin 48 hours before their CT scan.
This examination utilizes CT scan technology to acquire images of your patient's colon, instead of a camera. It is important that you request either "Virtual Colonoscopy" or "CT colonoscopy" in order to differentiate it from a regular colonoscopy.
Your patient must pick up 900 ml of Readi-Cat barium at WSMI before they begin their preparation.
This examination utilizes CT scan technology to acquire images.
Your patient resting heart rate must be 70 bpm or lower to undergo this exam, please prescribe Beta blockers if it is more than 80 bpm.
• Patients with severe arrhythmia cannot undergo the exam.
• Patients with a dual chamber pacemaker cannot undergo this exam.
You must advise them NOT to stop their regularly prescribed heart medication.
In the case of a MRI with contrast-agent injection (gadolinium), you must provide us with the creatinine level (blood report) of your patient done within the last six months for all patients 18 years old and younger, 60 years old and older, and under the following conditions for all others:
• If they are diabetic.
• If they are hypertensive.
• If they have suffered a heart attack or a stroke.
• If the have any kidney disease.
• If they take any blood thinners (e.g. Coumadin)
• If they had undergone chemotherapy in the last 3 months.
• If they had an organ transplant (e.g. renal, liver, heart)
Depending on the type of MRI your patient will be undergoing, a preparation might be required. Generally, the preparation for contrast-agent injection examination is of 3 hours of complete fasting. 12 hours of fasting is required in the case of MRCP. Your patients will be advised upon the coordination of their appointment.
If your patient is claustrophobic, a light sedative can be provided. In such a case your patient will not be allowed to drive 8 hours after the test and must be accompanied.
For breasts MRI, your patient must bring all images of their previous mammograms, ultrasound and other MRIs if they were performed in another clinic.
WSMI offers a wide range of ultrasound examinations such as Doppler's, thyroid and neck, breast, musculoskeletal, abdominal, pelvic, endovaginal, prostate and testicles.
Although it is important to provide our radiologists with the previous reports for a better comparison, your patients MUST bring their previous imaging for breast and musculoskeletal if theses films were done at another clinic.
Generally, only the abdominal, pelvic and endovaginal ultrasounds require a preparation.
