A mamm ogram detects cancers which are palpable but also those which we can’t feel. It uses small dose radiation which is safe. What is a Mammogram?Ī mammogram is essentially an Xray that takes a picture of the breast in its entirety. However, what is the difference between a mammmogram and a breast ultrasound scan? Are they painful? How long does it take? Read on to find out more. If there is a palpable change or lump in the breast, then an ultrasound scan can be helpful to focus on that specific area.ĭepending on your presenting problems as well as your age, you may either have a mammogram or breast ultrasound scan, or both. An ultrasound scan on the other hand is used more as a targeted scan. A mammogram is good at looking at the breast as a whole picture and therefore is useful as a surveillance tool. A radial sonogram obtained at the 5 o’clock position in the left breast shows a hypoechoic irregular mass.Ĭopyright: © Dr.Those attending a breast clinic most likely will get some sort of investigation. These two diagnostic investigations are quite different to each other. Nodal staging of breast cancer: still needed?Ĭaption: A 62-year-old woman with non-palpable 9 mm invasive ductal carcinoma only seen on ultrasound. Elastosonography: true advances or false hope? Veronica Girardi, Brescia, Italy Corinne Balleyguier, Villejuif, France Refresher Course: Breast Suzanne Diepstraten, from the radiology department at the University Medical Centre Utrecht in the Netherlands, will question the necessity of nodal staging of breast cancer. Elasticity imaging characteristics have actually been added to the latest version of the BI-RADS ultrasound lexicon.ĭr. Shear-wave elasticity or elastography may improve breast lesion characterisation and help better categorise undetermined lesions such as BI-RADS 4a and 3 nodules. Shear-wave elasticity imaging provides qualitative and quantitative analysis of a lesion, and is less dependent on the operator, she pointed out. The most common elasticity imaging technique is free-hand elastography, which is heavily dependent on the operator. Corinne Balleyguier from the diagnostic imaging department at Gustave Roussy Cancer Campus in Villejuif, France, as it improves the specificity of ultrasound. For this reason, the association of ultrasound to mammography in women with dense breasts has been proposed by many authors, although there is no evidence of mortality reduction,” she said.Įlastosonography offers potential, according to Dr. Breast density is associated with an increased risk of breast cancer at any age, but it does not seem to influence ultrasound accuracy. “When we consider breast density, there are two different issues: one is that it’s influencing cancer detection on mammographic imaging and the second is its possible independent effect on breast cancer risk. Veronica Girardi from the Istituti Ospedalieri Bresciani in Brescia, Italy. The masking effect of dense breast tissue is the most relevant cause of false-negatives, according to Dr. It is estimated that mammography sensitivity ranges from 65% to 91%. Wednesday, March 4 (ECR) – Imaging dense breasts or tissue abnormalities is still challenging in breast screening, but breast ultrasound continues to prove its utility, experts will show today in a Refresher Course at the ECR.
