While experts agree that image quality is the key to early detection and accurate
diagnosis of breast cancer, mammography, the current “gold standard” for breast
imaging, often fails to deliver what is needed. Although it is a high-spatial resolution
imaging modality, it cannot achieve contrast resolution sufficient to allow differentiation
of small structures from background tissue. Koning Breast CT (KBCT) achieves both
high spatial and contrast resolution.
Unlike whole body CT scanners, KBCT is the first fully integrated, dedicated CT
scanner designed specifically to image the entire breast, from the chest wall to
the nipple, with high spatial and contrast resolution. Traditional mammography is
a two-dimensional (2D) projection acquisition permitting structure and tissue overlap
which can obscure a breast lesion. KBCT images are displayed in both 3D and thin
multislice format to improve performance on structure and tissue overlap.
With its unique exam table and pendulous positioning of the breast, KBCT is able
to acquire a true 3D image of the entire breast. Prone positioning on the ergonomic
table ensures patient comfort. The self shielded design and the dedicated operator’s
console eliminate the need for a separate control room. Access to the patient is
available from wide interlocking safety covers on both sides, and the table can
be elevated to up to 1.5 meters: this makes it possible to perform other operations
such as biopsy.
Hundreds of images are captured in a single 10 second rotation of the gantry and
processed within seconds. Images are presented in both thin multislice multiplanar
projections and true isotropic 3D format, eliminating tissue overlap and superimposition
of structures common to 2D mammography. KBCT comes with a complete set of visualization
tools including side by side hanging protocols for comparison to previous mammograms.
KBCT is DICOM compliant for RIS/PACS connectivity and allows remote viewing from
up to 3 simultaneous locations (expandable if needed).
Diagnostic mammography requires breast compression, which is painful to women, and
a reason why many choose not to undergo further exams. Breast scanning with KBCT
is easier on women because it allows scanning the breast in its natural state without
having to pull, flatten and compress the tissue, eliminating the pain. Radiation
doses are within range of diagnostic mammography.
True isotropic 3D imaging and thin multislice formats available with KBCT can potentially
provide more diagnostic information. In a study to assess coverage conducted at
the University of Rochester Medical Center, KBCT was found to have better coverage
than mammography in the inferior, posterior, medial, and lateral aspects and equivalent
coverage in the superior aspect; in an overwhelming majority of cases, lesions were
equally or better visualized with KBCT than diagnostic mammography.
