Mammography
Mammography is a low dose X-ray of the breasts, done on digital equipment. The preparation is simple, but one detail makes all the difference:
- On the day of the exam, do not use deodorant, talc, cream or perfume on the breasts and armpits: they can show up on the image and get in the way of the reading.
- Arrive 15 minutes before your appointment.
- Bring your previous mammograms, if you have them. Comparing with older exams helps the radiologist.
- If you might be pregnant, tell the team.
During the exam, the breast is compressed for a few seconds between two plates. It may be uncomfortable, but the compression is quick and necessary for a sharp image with less radiation. If your breasts tend to be more sensitive before your period, it is worth keeping that in mind when choosing the date.
Ultrasound
Ultrasound uses no radiation, and the preparation depends on the area being examined:
| Exam | Preparation |
|---|---|
| Complete abdomen | 6 hour fast and 4 glasses of water 1 hour before |
| Upper abdomen | 6 hour fast |
| Urinary tract | 4 glasses of water 1 hour before |
| Pelvic (gynecological) and transabdominal prostate | 4 glasses of water 1 hour before |
A full bladder helps to see the pelvic organs better. Exams such as aortic Doppler, endometriosis screening and prostate biopsy have special preparation, with diet and medication: check the ultrasound page.
For ultrasound, arrive 15 minutes before, with your medical order, photo ID and CPF.
