What is the difference between a breast ultrasound and a mammogram?

Sound vs xrays. Mammograms use xrays to image the breast tissue. Screening mmgs involve 2 views (mlo, cc) of each whole breast. Ultrasound uses sound waves to produce images of the breast tissue. The area visualized is dependent upon where the probe is placed on the breast and is influenced by how it is angled, how fast it is moved around and how much attention is being paid to the screen during the exam.
Difference. A mammogram is a special type of xray of the breasts. Typically, two views of each breast are taken during the initial (screening) mammogram. A breast ultrasound has no radiation and is used to evaluate a finding on a mammogram or to assess a lump felt by the patient. It is able to differentiate cysts from solid masses.
Mammo vs ultrasound. A mammogram is a low dose X-ray of the breasts. An ultrasound utilizes sound waves to generate images. Mammo is currently the standard of care for screening, ultrasound has an adjunct or problem solving role.

What is the difference between an breast ultrasound and a mammogram?

Mammogram/Ultrasound. The mammogram (mg) and ultrasound(us) show breast tissue in different ways. The mg is better for women with fatty breasts. The us can help tell if a mass is solid or cystic (fluid filled). It can also give a better picture for women who have dense breasts. The tests are often used together to help determine what is going on. Read more...

What is the difference between an ultrasound of breast and a mammogram?

Sonar vs Xray. Breast ultrasound use sound waves (i.e. Sonar) and are used to determine if a lump is solid, (usually require biopsy) or a cyst (a fluid containing lesion, usually not requiring biopsy). Mammograms also detect tumors in the breast and have the advantage of detecting tiny calcification deposits that my be due to cancer. Both tests work together to find breast cancer. No test replaces the other. Read more...

What is the difference between screening mammogram and diagnostic mammogram? Why does the diagnostic one have to be done with breast ultrasound?

Purpose. The purpose of a screening mammogram is to identify breast cancer in women who have no signs of disease, while the purpose of a diagnostic mammogram is to obtain more detail on a known abnormality identified on prior physical exam or imaging study. A diagnostic mammogram need not always be done with an ultrasound. Read more...
A screening. mammogram is a study of both breasts that is performed on asymptomatic women to try and detect signs of breast cancer. A diagnostic mammogram consists of special views, and is usually targeted to a specific area of the breast, to further evaluate a potential abnormality seen on screening mammo or felt on clinical exam. The diagnostic doesn't have to have an US, but US usually very helpful. Read more...

Misdiagnosis with breast ultrasound? Is it possible to have differing results from an ultrasound and a mammogram? In my case, the mammogram didn't show anything but an ultrasound did. Which method is usually more reliable and how does this happen?

Yes, . Yes, results from an ultrasound can differ from the findings on a mammogram. Each imaging modality has its own strengths and weaknesses. The resolution of mammography is far superior to that of ultrasound. Mammography can detect tiny microcalcifications that could never be detected on ultrasound. Ultrasound is excellent at detecting cysts and can be used to evaluate blood flow in the area of interest. Many lesions often appear very subtle on a particular imaging study, but can be much more obvious on a different imaging modality. For this reason, it is extremely important for the radiologist to compare the images obtained in both studies. Ultrasound and mammography are complementary studies that should be used together to arive at the most likely diagnosis. The most reliable result is the one obtained after completing all imaging studies and analyzing the findings together in order to achieve the most likely diagnosis. Read more...
The mammogram. A mammogram gives a lot more detail than an ultrasound. If a lump is detected, further studies are needed. If the mammogram is negative, waiting a few months or doing an MRI are some ways to go. Read more...
They are. complementary tests, imaging different tissue characteristics. It is not unusual for an abnormality to be seen on one and not the other. If you have dense breasts, it is especially true that an ultrasound abnormality may be invisible on mammo due to the density. Not seeing it on both does not negate a finding on one. Read more...

Is breast ultrasound as effective as a mammogram?

No. There are 3 mainstream modalities of breast imaging - mammogram, ultrasound and breast mri. Each of these has its strengths and weaknesses. Mammogram is used as a screening tool for all women in the us because it gives the best overall picture. The ultrasound is most commonly used to help discern between a cyst and a solid lesion.

US vs mammo. It depends on what you mean by effective.The sensitivity of screening mammo and screening US is close, with US detecting 3-4 cancers per 1000 patients and mammo detecting 4-5.US performs better in the dense breast category, mammo performs better in fatty breasts. Their roles are complementary, and evolving. The current main role of US is to further evaluate abnormalities seen on mammo or exam. Read more...

US and mammo. US generally used to further evaluate mammographic or palpable abnormalities. One of the main strengths is the ability to differentiate solid masses from cysts, which mammo can't do.

I go soon for an diagnostic mammogram. Will I need a breast ultrasound?

Sometimes. An ultrasound is simply another means of looking at breast (or other soft) tissues. It is not usually ordered routinely in conjunction with a mammogram unless there is something abnormal on the ultrasound or a mass that is palpable. Read more...
Maybe. If you have microcalcifications, the mammographer may want a magnification view only and no ultrasound. But for most other things (typically masses or significant asymettry) and ultrasound is helpful. Read more...
Perhaps. An ultrasound may be useful to better define a density ("lump") or an area of asymmetry ("shadow") seen on mammography! however, it is of no benefit when evaluating microcalcifications. Ideally, the breast canter where you have your diagnostic mammogram will be able to perform the ultrasound the same day, if they recommend one. Read more...
Possibly.... If you had the diagnostic mammogram for something you can feel, like a lump, then you will almost certainly need an ultrasound. If you were called back for calcifcations, you most likely will not need an ultrasound. If a mass was seen on the mammogram, that you cannot feel, you will also need an ultrasound. Read more...
