Naviscan Announces European Launch of Positron Emission Mammography

VIENNA, March 2, 2011 /PRNewswire/ -- Naviscan, Inc., announces the European launch of the Naviscan Positron Emission Mammography (PEM) scanner at two prestigious radiology conferences in Vienna. On March 3rd, at the European Society of Breast Imaging (EUSOBI) Annual Scientific Meeting, a podium presentation will focus on recently published PEM (Positron Emission Mammography) data demonstrating PEM's ability to reduce unnecessary biopsies by providing superior specificity, the ability to differentiate between benign and malignant lesions. Simultaneously at the European Congress of Radiology (ECR) conference, March 3 - 7, a poster will be presented featuring new clinical data on the role of PEM for assessment of axillary lymph node (ALN) status in patients with breast cancer.

PEM scanners are high-resolution breast PET systems (also referred to as 3-D Molecular Breast Imagers or Tomographic MBI) that can show the location as well as the metabolic phase of a lesion. This information is critical in determining whether a lesion is malignant and influences the course of treatment. PEM scanners, which are about the size of an ultrasound system, are manufactured by Naviscan, Inc. and have been commercially available since 2007.

The poster will highlight new clinical data from researchers at the University of Chicago on the role of PEM for assessment of axillary lymph node status in patients with breast cancer. Current morphology-based tools for ALN staging include clinical examination, axillary ultrasound and breast MRI, but none are accurate enough to replace the need for pathologic evaluation of the axillary nodes.

Breast cancer screening with MRI benefits women with radiation therapy history

OAK BROOK, Ill. – Breast cancer screening with MRI can detect invasive cancers missed on mammography in women who've undergone chest irradiation for other diseases, according to a new study published online and in the April print edition of Radiology.

Women who receive radiation therapy as children and young adults for diseases like Hodgkin's lymphoma face a significantly greater risk of breast cancer later in life. The incidence of breast cancer increases approximately eight years after chest irradiation, and 13 percent to 20 percent of women treated with moderate- to high-dose chest irradiation for a pediatric cancer will be diagnosed with breast cancer by age 40 to 45. In comparison, the cumulative incidence of invasive breast cancer by age 45 among women in the general population is only 1 percent.

"MRI's efficacy as an adjunct to mammography in screening women at high risk because of genetic mutation or family history has been established," said the study's lead author Janice S. Sung, M.D., radiologist at Memorial Sloan-Kettering Cancer Center (MSKCC) in New York City. "However, there were no reports in the literature about utility of MRI screening in women who are at high risk specifically due to prior chest irradiation."

In the study, Dr. Sung and colleagues reviewed screening breast MRIs performed at MSKCC between January 1999 and December 2008 on women with a history of chest irradiation. They looked at data from 247 screening breast MRIs in 91 women, with a focus on the number of cancers diagnosed, the method of detection and the tumor characteristics.

Of the 10 cancers found during the study period, four were detected with MRI alone, three with MRI and mammography, and three with mammography alone. The four cancers detected with MRI alone were invasive, while the three cancers detected with mammography alone were in their early stages.

Preoperative Breast MRI Suggests High Cancer Yield and Positive Predictive Value in Newly Diagnosed Patients, Study Finds

The use of preoperative Breast MRI detects otherwise occult cancer with a relatively high degree of accuracy when applied to a diverse population of patients newly diagnosed with breast cancer, according to a study in the January issue of the American Journal of Roentgenology.

The study was performed at the University of Washington and Seattle Cancer Care Alliance in Seattle, WA. The review initiated with 592 patients who were recently diagnosed with breast cancer and underwent staging with preoperative breast MRI. The analysis set was comprised of 570 patients, whose biopsy rates, positive predictive values (PPVs) of biopsy, and overall cancer yields were calculated and compared using the chi-square test across patient age, breast density, index tumor type, receptor status and lymph node status.

“Our data add to the growing body of literature that documents breast MRI's ability to detect otherwise occult additional disease in patients who have been newly diagnosed with breast cancer,” said Robert Gutierrez, MD, lead author of the study.

“We found that use of preoperative breast MRI in newly diagnosed cancer patients resulted in an added cancer yield of 12%.This is much higher than the added cancer yield of .08 to 6.7% seen with high risk screening breast MRI, a more widely accepted indication for breast MRI,” said Gutierrez.

Advances in Breast Imaging Improve Patient Care, Aid in Earlier Cancer Detection

OREM, UT, December 16, 2010 /24-7PressRelease/ -- The new KLAS "Breast Imaging 2010: A More Complete Picture" report takes an all-inclusive look at breast imaging technologies from a patient perspective, beginning with digital mammography and moving through CAD, MIS and ending with a discussion of newer breast-specific imaging technologies. Providers were noticeably energized about breast-specific imaging units such as the Dilon 6800 Gamma Camera and U-Systems somo-v INSIGHT whole breast ultrasound. However, because reimbursements vary, ROI occasionally takes a hit.

"Providers are looking for more patient-friendly imaging options and the U-Systems ultrasound fits the bill because it's a non-invasive, no-dose exam. Some physicians we spoke with mention that whole breast ultrasound would be a great screening tool, but currently most providers cannot get reimbursed for screening with the ultrasound," said Emily Crane, co-author of the report. "Digital mammography is still more cost effective for providers--and currently the only approved screening tool."

The wider adoption of CAD and MIS systems has also helped to increase ROI for digital mammography. Providers report that both systems increase the efficiency and workflow for breast imaging.

Novel Imaging Technique May Reduce Lymphedema in Breast Cancer Patients

SAN ANTONIO — With guidance from a specialized scan, radiation oncologists at Mayo Clinic were able to reduce by 55 percent the number of lymph nodes critical for removing fluid from the arm that received damaging radiation doses.

The researchers report that integrating single photon emission computed tomography(SPECT) with the computerized tomography(CT) scans utilized for breast cancer radiotherapy planning may offer patients substantial protection against lymphedema, an incurable, chronic swelling of tissue that results from damage to lymph nodes sustained during breast cancer radiation. The SPECT-CT scan pinpoints the precise locations of the lymph nodes that are critical for removing fluid from the arm, allowing physicians to block them, as much as possible, from X-ray beams delivered to the chest.

These findings were presented at the 33rd Annual CTRC-AACR San Antonio Breast Cancer Symposium.

Radiology Journal Publishes Data That PEM Scanners May Reduce Unnecessary Breast Biopsies And Offer An Alternative For Women Who Cannot Tolerate MRI

The Radiology journal released new data from an NIH-sponsored, multi-site study of hundreds of women with newly diagnosed breast cancer that shows Positron Emission Mammography (PEM) may reduce unnecessary breast biopsies. The study found that PEM was significantly more precise at identifying benign and cancerous lesions, in what scientists call "Positive Predictive Value" or "PPV," therefore reducing the number of unnecessary biopsies. A common physician complaint regarding the use of Breast MRI is its tendency to identify suspicious lesions, requiring biopsies, which ultimately are found to be benign.

This finding is a welcomed outcome for women and physicians looking for ways to reduce the patient trauma associated with biopsies and for payors looking to reduce the costs associated with unnecessary procedures. The 388 woman study showed that PEM not only demonstrated a six percent improvement in specificity at comparably high sensitivity, but that PEM also had 31 fewer unnecessary biopsies and 26% higher PPV than Breast MR.

FDA Reclassifies Certain Digital Mammography Devices

The U.S. Food and Drug Administration announced that it is easing the pathway to market for mammography systems that produce computerized X-ray images of the entire breast.

These systems, known as Full Field Digital Mammography Systems, are an alternative to mammography systems that produce X-ray film.

When first approved by FDA in 2000, digital mammography systems were categorized as a high risk or Class III device, because they were then considered novel systems for screening and diagnosing breast cancer.

Since then, digital mammography has been well-validated in scientific studies involving tens of thousands of patients. The benefits and risks of digital versus film mammography have also been well -described to physicians. As a result, the FDA has decided to reclassify digital mammography from Class III devices to Class II or medium risk devices.

Study Determines Breast-Specific Gamma Imaging Is More Effective Than Ultrasound in Patients With Complex Breast Tissue

WASHINGTON, Oct. 6 /PRNewswire/ -- Results of a study on Breast-Specific Gamma Imaging (BSGI) presented at the annual breast meeting of the American Society of Clinical Oncology in Washington, D.C., showed that BSGI was nearly twice as effective in finding cancers and more than three times as likely to lead to the correct diagnosis when compared to ultrasound.

Breast-specific gamma imaging (BSGI) is a molecular breast imaging technique being used more frequently as a diagnostic tool in breast centers across the nation. BSGI complements the anatomical imaging of mammography and is performed using an injection of the radiopharmaceutical Sestamibi, an imaging agent that when paired with breast-optimized gamma cameras helps determine the function of breast tissue.

A dedicated breast surgeon in Philadelphia, Dr. Ann Rosenberg, was the lead author on the retrospective, multicenter study. Rosenberg and her group compared the results of BSGI and ultrasound in patients who had dense breast tissue and a remaining diagnostic concern after mammography. The study was performed using a Dilon 6800 Gamma Camera with the standard recommend dose of approximately 20 millicuries of Sestamibi. The results show that BSGI was nearly twice as effective in finding cancers and more than three times as likely to lead to the correct diagnosis when compared to ultrasound.

Preliminary Research Results Suggest Up To 70% Reduction In Dose For Positron Emission Mammography Imaging

In a recent study presented at the American Association of Physicists in Medicine (AAPM) 52nd Annual Meeting, researchers at the University of Washington showed that 18FDG dose for Positron Emission Mammography (PEM) may be reduced by as much as 70% without altering image quality.

PEM scanners are high-resolution breast PET systems that show the location as well as the metabolic phase of a lesion. The metabolic view assists physicians to make the optimal cancer care decision by providing an unprecedented ability to distinguish between benign and malignant lesions, what researchers term "specificity." PEM is different than x-ray mammography in that it is currently not used as a screening modality, rather is deployed to confirm extent of disease in a patient already diagnosed with a primary breast cancer.

"We have several tools to help us make better patient care choices. Mammography is our primary screening tool. PEM is used in women with known breast cancer in order to plan treatment," said Wendie Berg, MD, Breast Imaging Radiologist, Lutherville, MD. "Radiation for treatment of breast cancer uses doses which are roughly 5000 times higher than a diagnostic PEM study. Minimizing radiation dose is still important for any patient, and we can likely cut the dose of PEM in half, but the benefit to proper treatment exceeds the still low risk from the radiation dose of PEM."
