While conventional mammography takes pictures of the breast from two angles — up and down, and left and right — tomosynthesis takes multiple pictures from different angles. Benefits of tomosynthesis include improved imaging for patients with dense breast tissue. Tomosynthesis can also decrease recall rates for screening mammography. Board-certified radiologists at Magee-womens Imaging may use tomosynthesis in conjunction with conventional mammography to provide the most optimal image of your breasts for a clear diagnosis. The actual tomosynthesis procedure is no gpa different than having a conventional mammogram and typically take 30 minutes to complete. Learn what to expect during your mammogram.

A radiologist, who is a physician with specialized training in x-ray and other mba imaging tests, will analyze and interpret the results of your exam and then send a report to your personal physician. For non-emergency situations, it usually takes a day or so to interpret, report, and deliver the results. Contact your personal physician for information on the results of your exam.

Tomosynthesis machine (very similar to a mammography machine.

Upmc content 2, upmc content 3 3d mammography, also referred to as Tomosynthesis, is an imaging procedure that uses low-energy x-rays to create a 3D image of the breasts.
A normal (negative) exam is not a guarantee that a woman is cancer-free. When a mammogram appears normal, but cancer is later found the mammogram is called a false negative exam. The false negative rate is estimated to be 15-20; higher in younger women and women with dense breasts. A mammogram may show areas that are considered suspicious or not normal. . When this happens additional testing is usually suggested, such as additional mammograms, ultrasound, mri imaging or a breast biopsy. . When the mammogram shows a suspicious change in the breast but no cancer is found, the mammogram is called a false positive exam. It is estimated that 75-80 of all breast biopsies resulted in benign results (no cancer is found). Results: Mammograms and Tomosynthesis exams can be recorded digitally and stored electronically on computers. Some mammograms are recorded on film.

Immediately after the x-ray is taken the pressure is released. . Compression needed for a tomosynthesis exam is usually about the same as that for a regular mammogram. For a mammogram, two x-rays of each breast are taken. . For a tomosynthesis scan, the breast will be held in place while a special tube rotates around writers the breast. This should take about 10 seconds.
You will not feel the radiation. Time required: 15-30 minutes, noise during Exam: Minimal clicking or buzzing noises. Space during Exam: you will stand next to the x-ray machine with ample space around you. Benefits: X-ray exams are fast and easy. The equipment used is relatively inexpensive and widely available. Risks: The risk of radiation from a mammogram is considered minimal and not significant. Some breast cancers do not show up on mammograms or hide in dense breast tissue. .
If this is the case, she may want to schedule the exam 1-2 weeks after her period when breasts tend to be less tender. In some women, caffeine-containing products (cola, coffee, chocolate) could make breasts more tender. Women who are sensitive should limit caffeine intake for 2 weeks prior to exam. If you have had prior mammograms performed at other imaging facilities, notify your doctor so that the previous study may be requested for comparison. Tell the technologist if you have breast implants. Women should inform their doctor if they are or may be pregnant or nursing prior to any radiological imaging.
Your doctor may recommend another type of test to reduce the possible risk of exposing your baby to radiation. During the Exam: you will be asked to remove all clothing and jewelry above the waist. . you will be given a gown to wear. . you will be asked to stand in front of a special mammography x-ray machine. . The radiology technician will place the breast between 2 plastic plates. The technologist will press the breast between the two plates. This compression may be uncomfortable for a few seconds while the x-ray is taken. You will be asked to hold very still, without breathing for a few seconds. The technologist will step behind a radiation barrier and activate the x-ray machine.

It takes less than 10 seconds reviews for the imaging. . The information from the x-rays is sent to a computer, which produces a focused 3-d image of the breast. The x-ray dose for a tomosynthesis image is similar to that of a regular mammogram. Preparation for a mammogram or tomosynthesis scan. Wear 2-piece clothing (top and pants/skirt) to simplify undressing for exam. Do not apply mattress talc, deodorant, oils or creams on your upper body the day of the exam. Some women experience breast tenderness with their menstrual cycle.
The images obtained during x-ray exams may be viewed on film or stored digitally and viewed on a computer screen. Mammogram: A mammogram is an x-ray exam of the feasibility breast. A special machine designed specifically to examine breast tissue is used. It takes a different form of x-ray and uses lower doses of radiation than a usual x-ray. Because these x-rays do not go through breast tissue as easily, the mammogram machine has two plates that compress the breast to spread the tissue apart. A more accurate image is obtained with less radiation this way. Tomosynthesis : Tomosynthesis is a special kind of mammogram that produces a 3-dimensional image of the breast by using several low dose x-rays obtained at different angles. . For tomosynthesis, the breast is positioned and compressed in the same way as for a mammogram but the x-ray tube moves in a circular arc around the breast. .
used to create an image of the inside of your body. This beam is directed at the area being examined. After passing through the body, the beam falls on a piece of film or a special plate where it casts a type of shadow. Different tissues in the body block or absorb the radiation differently. Dense tissue, such as bone, blocks most of the radiation and appears white on the film. Soft tissue, such as muscle, blocks less radiation and appears darker on the film. Often multiple images are taken from different angles so a more complete view of the area is available.
In fact, both images are taken at the same time, on the same scanner. And just as with a 2D digital mammogram, the technologist positions the patient, compresses their breast under a paddle and takes images from different angles. During the 3D portion of the exam, the machine's x-ray arm makes a quick arc over the breast, taking a series of images at a number of angles. Tomosynthesis adds no time to the exam, with the entire procedure taking approximately the same amount of time as that of a 2D mammogram. This image illustrates the differences in 2D and 3D breast imaging. In the "conventional" 2D mammogram (pictured left save there is an apparent area of concern that may require additional studies, like another mammogram or a biopsy. Instead, looking at the same breast tissue in a succession of 3D images (pictured right doctors can now see that the tissue is, in fact, normal breast tissue that was simply overlapping in the traditional mammogram, thus creating the illusion of an abnormality. In this scenario, the patient likely avoided a callback for an additional mammogram—and the anxiety that goes along with it—thanks to tomosynthesis technology).

From a patient's point of view : A 3D mammogram exam is very similar to a 2D gpa mammogram—both are performed together on the same scanner. Just as with a digital mammogram, the technologist will position you, compress your breast under a paddle, and take images from different angles. During the 3D portion of the exam, the x-ray arm of the machine makes a quick arc over the breast, taking a series of breast images at a number of angles. The entire procedure should take approximately the same amount of time as a 2D mammogram. From a technical point of view: The technologist sends your breast images electronically to the radiologist, who will examine breast tissue one layer at a time instead of viewing all the complexities of your breast tissue in a flat image. Fine details can be more clearly visible, less likely to be hidden by the tissue above and below. This image depicts a tomosynthesis experience from the patient's point of view. A 3D mammogram exam is very similar to a 2D mammogram.
