3D mammography

Grant Regional offers Genius™ 3D MAMMOGRAPHY™ exams, developed by Hologic, Inc., a worldwide leader in Women's Healthi. Utilizing advanced breast tomosynthesis technology, Genius exams are clinically proven to significantly increase the detection of breast cancers, while simultaneously decreasing the number of women asked to return for additional testing.*

In conventional 2D mammography, overlapping tissue is a leading reason why small breast cancers may be missed and normal tissue may appear abnormal, leading to unnecessary callbacks. A Genius exam includes a three-dimensional method of imaging that can greatly reduce the tissue overlap effect.

A Genius exam includes both 2D images and tomosynthesis scans. During the tomosynthesis-DIMENSIONAL portion of the exam, an x-ray arm sweeps in a slight arc over the breast, taking multiple images. A computer then converts the images into a stack of thin layers, allowing the radiologist to review the breast tissue one layer at a time. A Genius exam requires no additional compression and takes just a few seconds longer than a conventional 2D breast cancer screening exam.

The Hologic system is the only clinically superior breast tomosynthesis system as approved by the FDA. The new system is recommended for women of all ages and breast densities. The system allows our radiologists to more effectively pinpoint the size, shape and location of abnormalities. This leads to better detection and greater peace of mind for our patients.

Large clinical studies in the U.S. and Europe have demonstrated the positive benefits of a Genius 3D MAMMOGRAPHY™ exam. The largest study to date on breast cancer screening using the Genius exam was published in the June 25, 2014 issue of the Journal of the American Medical Association (JAMA)ii. Findings include:

  • A 41% increase in the detection of invasive breast cancers.
  • A 29% increase in the detection of all breast cancers.
  • A 15% decrease in women recalled for additional imaging.

About Genius™ 3D MAMMOGRAPHY™ Exams

The breast is a three-dimensional object composed of different structures located at different heights within the breast. These structures can overlap and cause confusion when viewed as a flat two-dimensional image. This confusion of overlapping of tissue is a leading reason why small breast cancers may be missed and normal tissue may appear abnormal, leading to unnecessary callbacks. Using breast tomosynthesis technology, the Hologic system creates a 3-dimensional image of the breast structure, which enables radiologists to more clearly see through overlapping tissue to detect cancers, often at an earlier stage.

The Hologic system is the first FDA-approved breast tomosynthesis system in the U.S. Hologic Genius 3D MAMMOGRAPHY™ exams are now available in all 50 states and over 50 countries. To date, more than 8 million women have been screened with this advanced screening system.

iGenius™ 3D MAMMOGRAPHY™ exams are available only on the Hologic Selenia® Dimensions® system.

Digital mammography

Grant Regional Health Center (GRHC) now offers the latest diagnostic technology available in digital mammography with the introduction of our new Selenia Dimensions digital mammography machine from Hologic for breast cancer detection.

Digital mammography is the latest advancement in breast imaging. It uses computers and specially designed digital detectors to produce an image that can be displayed on a high-resolution computer monitor and transmitted and stored just like computer files.

Digital mammography provides high-quality breast images and special tools that allow the radiologist to see more detail than ever before. This advanced imaging technology helps clinicians detect breast cancer at the earliest stage possible.

"Our investment in digital mammography supports our commitment to improving the health in our region," says Nicole Clapp, GRHC President/CEO. "We also offer the added technology of the PACS digital image archiving system, which is networked to accurately store and retrieve digital images. This system allows radiologists and providers at multiple locations to view and interpret images simultaneously."

Grant Regional Health Center is proud of the sizeable investment of $450,000 to improve technology. Donations totaling over $30,000 in support of this service enhancement and the fight against breast cancer were also given to GRHC Foundation's annual campaign this past year.

In November 2011, the GRHC Radiology Department completed its annual inspection, meeting the quality standards of Mammography Quality Standards Act with a "no findings" rating, the highest rating possible. This routine inspection certifies that the GRHC Radiology Department understands the current regulations and has successfully passed the required quality control tests. GRHC is also accredited by the FDA every three years. In order to retain accreditation, GRHC must send images and staff continued-education information to the FDA to ensure quality imaging.

"Breast cancer is the second leading cause of cancer death among women, exceeded only by lung cancer. Statistics show that 1 in 8 women will develop breast cancer sometime in her life. The stage at which breast cancer is detected influences survival chances," said Christie Schwager. "If detected early, the five-year survival rate is 97 percent."

With new digital technology, images appear on the technologist's monitor in seconds, Schwager said, which means less time in the breast imaging room for the patient. Because there is no waiting for film to be developed, it significantly reduces the need for repeat exams due to under- or overexposure, said Schwager. With digital mammography, radiologists review electronic images of the breast and can adjust the brightness, change the contrast and zoom in for close-ups of specific areas of interest, Schwager said. "Being able to manipulate images is one of the main benefits of digital technology, along with reduced radiation exposure."

Women should have their first mammogram between the ages of 35 and 40, Schwager said. Annual mammograms are recommended for women over 40. More than 70 percent of breast cancer occurs in women who have no identifiable risk factors, said Schwager. "Risk is higher as you get older, and having a first-degree relative with breast cancer approximately doubles a woman's risk."
