Effective 1/2021, the American Medical Association provided Breast CT with 6 dedicated CPT codes. The codes are now being accepted by both public and private payers.

Surveys have shown the majority of women who receive mammograms consider the experience to be painful due to compression. Unfortunately, all mammograms require rigorous breast compression which is the only way for 2-dimensional mammography X-rays to penetrate the breast tissue.

Additional surveys have shown, pain from compression leads many women to forego the recommendations to obtain an annual mammogram. Not complying with the recommendations often results in late-stage cancer diagnoses where treatment outcomes are not as promising in comparison to cancer found earlier.

Breast CT, “KBCT”, is the first X-ray-based breast imaging device that does not require painful compression and produces a true 3-dimensional image of the breast at the same dose as a 2-dimensional compressional mammogram and the exam time is a rapid 7 seconds per breast. Koning believes the vast majority of women will find this a welcome improvement from mammography and Breast CT should have a positive impact on those currently not complying with the recommendations.

Compressional DBT has been marketed as 3D when, in fact, it is not true 3D. For an image to be true 3D it must be “isotropic” (the same from any angle). Breast CT is true 3D – the image can be viewed from any angle equally, which eliminates any overlapping structures. It acquires true 3D images without compression.

On average, a bi-lateral exam can be completed in under 5 minutes. Timing is not limited to the machine. Each breast scan takes 7 seconds. The rest of the timing is for the patient to enter the room and be properly positioned on the table.

The Breast CT prone biopsy is rather quick depending on the patient. The average biopsy can be completed in 20 to 25 minutes. The two most important factors regarding Breast CT biopsy are targeting accuracy by utilizing isotropic 3D targeting and the ability to reduce the number of images which equates to a radiation exposure level which is 50% less dose when compared to stereo biopsy.

Over 130 papers have been published on the technology. Please visit Our Publications for access to the papers.

• Unilateral or bi-lateral imaging of the breast with or without contrast.
• X-ray guided 3-dimensionally targeted biopsy
• Contrast-enhanced imaging when indicated
• Breast implant imaging without displacement views
• Neoadjuvant therapy monitoring imaging

We suggest a minimum of 10” x 14’ room size and the electric power requirement is the same as mammography – 208 to 240 Volt, 35 Amp single phase.

The room doesn’t require special shielding. KBCT can be installed with an operator console with a glass shield as extra protection to the technologist.

Scientific articles have been published in peer-reviewed journals and conferences. Recent studies show that: 1. CBBCT has comparable diagnostic performance to breast MRI in patients with high suspicion of or known breast malignancy and should be considered as a substitute in patients that cannot undergo breast MRI. —- SBI 2022 2. CE-CBBCT showed substantial agreement and comparable inter-reader reliability with MRI for BPE evaluation. —- Journal of European Radiology, 2022, vol.32 3. CE-CBBCT is concordant with surgical pathology in breast tumor size measurement. Compared with bMRI, CE-CBBCT provides more accurate tumor size estimation among invasive ductal carcinoma lesions, small size (≤2cm) lesions and premenopause patients. CE-CBBCT can be used as a valuable modality for pre-operative assessment. —— San Antonio Breast Cancer Symposium 2022

The current studies have demonstrated at least equivalent diagnostic effectiveness between KBCT and MRI. Large-scale comparison study directly compare the sensitivity, specificity and AUC of KBCT and MRI has yet to be carried out and published.
