DIGITAL MAMMOGRAPHY & BREAST ULTRASOUND
We provide a full range of diagnostic breast services for our female patients including:
1. Digital Mammography with Computer Aided Detection (CAD)
2. Breast Ultrasound
3. Ultrasound Guided Fine Needle Aspiration
4. Ultrasound Guided Breast Biopsy
At Lifescan Imaging, we have a Full Field Digital Mammography (FFDM) machine which decreases the radiation dose, shortens the time taken to perform mammography and enhances your mammography experience. Early breast cancer usually presents as microcalcifications (tiny calcium dots) and digital mammography is good at picking up microcalcifications in the breast.
Computer Aided Detection Software
Computer Aided Detection (CAD) is a FDA approved technology that helps radiologists to analyse your mammogram. It does not replace the radiologist but acts as a second pair of eyes, very much like a “spellchecker”, helping to identify certain features in a mammogram that may need further evaluation. Studies have shown that CAD increases the sensitivity of picking up a cancer by about 10%.
Frequently Asked Questions
During the peri-menstrual period, the nipple is more sensitive and engorged. It would be best to avoid the pre-menstrual/menstrual period and have the mammogram performed about 1 to 2 weeks after the menstruation period.
It is best to wear 2 piece clothing i.e. a top and a pair of pants so as to ease the process of removing the top during mammography.
The powder, deodorant, cream or perfume may cause artifacts on the mammography image. The artifacts appear as white spots on the mammography film which may mimic microcalcifications that may be a representation of early cancer.
Mammography has a false negative rate of about 10% which means even though it might be reported as normal, up to about 10% of normal mammograms may hide a small cancer especially in Asian women where the breast tissue is very dense. At Lifescan Imaging, we have full field digital mammography and CAD (computer aided detection) software which helps to pick up small early cancers.
Mammography is the only imaging test that has been shown to reduce mortality (death rate) by about 30%. The Singapore Ministry of Health recommends that all women 40 years old and above should undergo screening mammography.
It is important to bring all your old films, especially if it has been performed in another imaging centre as small subtle changes can be better demonstrated when compared to previous mammograms.
After reviewing your mammogram, in about 10% of cases, more views may be ordered by the radiologist to evaluate any indeterminate findings.
Findings on mammograms or breast ultrasound may be non-cancerous (simple cysts etc) or some findings are typical for cancer (irregular spiculated mass). Sometimes however, findings are indeterminate. When the findings are indeterminate or not conclusive, a recommendation for biopsy (removal of some tissue) is made.
Results are usually available in 1 to 2 working days.
