Even though questions are still continuing for the best possible way to detect breast cancer early, a CT Imaging system which has been developed at the University of Rochester Medical Center which was first made known five years earlier is now in a greater position to enter the fight in playing a supporting role to the conventional mammography.
Dr. Avis O’Connell, radiologist from URMC had received an invitation from the Radiological Society of North America Annual Scientific Assembly in Chicago, Illinois, to recap the studies administered so far on the Cone Beam Computed Tomography(CBCT) scanner.
Dr. O’Connell is encouraged about the progress. The CBCT gives high quality images and of most importance is easier on women for it lets precise breast scans without pulling, flattening and compressing the tissue.
Also, beginning research has shown some major advantages over the current imaging devices. Its most promising capability just maybe it can be used as an additional tool in the diagnoses of difficult cases.
It maybe greatly useful in the location of tumors which are hidden by dense breast tissue, or determining between benign and malignant lesions according to Dr. O’Connell, associate professor in Imaging Science and director of woman’s imaging for the Comprehensive Breast Care Center at the James P. Wilmot Cancer at URCM.
A research team at the university had introduced the CBCT system at the 2006 RSNA meeting. A great many women sought information about enrolling in clinical trails to test the new device. The women noted they were anxious for participation in the research which could bring a more comfortable and precise, annual mammograms.
The CBCT scanner generates three-dimensional images while the breasts are in a more natural state. (Tomosynthesis another device being developed for breast scanning. It builds a 3D picture of the breast by way of multiple x-rays, where the CBCT is a actual 3D image.) When receiving the CBCT scan, the woman lies on her stomach on a cushioned exam table – the design is still undergoing improvements, as one breast at a time is suspended through an opening in the table. The radiation sources is placed in a way so that exposure to other areas such as chest and torso is avoided.
The CBCT scanner takes 300 high resolution images while it circles the breasts for around ten seconds. It produces a dose of radiation that is equal to diagnostic mammogram and within limits set by the FDA. Radiologists will also be able to use the CBT images and associated software to perform biopsies directly on the table states Dr. O’Connell.
An initial trial was conducted on 23 women who were acknowledged to be cancer free and had to have a routine mammogram screening they had also volunteered to undergo scans on the CBCT. The only objective of the study was for the determination of image quality, coverage and radiation dose.
