2. Guidelines and Preparations
Digital Mammography
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:
| AGE | CRITERIA | MAMMO | U/S |
| 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 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.
