Microbubble ultrasound and breast biopsies

Using "microbubbles" and ultrasound can mean more targeted breast biopsies for patients with early breast cancer, helping to determine treatment and possibly saving those patients from undergoing a second breast cancer surgery, a new study in shows.

Patients with early breast cancer undergo a sentinel lymph node biopsy to determine if their cancer has spread, said Dr. Ali Sever, lead author of the study. Ultrasound, on its own, can't distinguish the sentinel lymph node from other lymph nodes, Dr. Sever said. However, "our study found that microbubble contrast- enhanced ultrasound accurately identified the sentinel lymph node in 89% of the 80 patients in our study."

As many as 35% of patients who undergo sentinel lymph node excision biopsy will require additional surgery because cancer has spread," Dr. Sever said. Using microbubble contrast-enhanced ultrasound preoperatively means that the cancer and cancer spread can be removed during one operation.

Currently blue dye and radioisotopes are used to identify sentinel lymph nodes at the time of surgical excision. While this technique is accurate, there are side effects for some patients, including an allergic reaction. In addition, the disposal of the radioisotopes (radioactive waste) poses an issue.

Contrast-Enhanced Ultrasound Improves Diagnosis of Medical Conditions in Children

ROTTERDAM, Netherlands--(BUSINESS WIRE)--New research released here Thursday shows that “contrast-enhanced ultrasound” (CEUS) can safely improve the diagnosis of a variety of medical conditions in children – without exposing them to ionizing radiation.

Dr. Martin Stenzel, a pediatric radiologist at the University Hospital in Jena, Germany, reported that no adverse safety event was found when CEUS was used to image some 50 pediatric patients at his hospital.

Stenzel presented his findings at the 16th European Symposium on Ultrasound Contrast Imaging in Rotterdam. The conference, which was co-sponsored by the International Contrast Ultrasound Society (ICUS), featured the latest clinical and research developments in the CEUS field.

“Our experience shows that this technology works in children as well as adults,” Stenzel said.

The youngest patient Stenzel and his colleagues examined with CEUS, was two years old, he said.

Unlike CT and nuclear imaging, ultrasound scans do not expose patients to ionizing radiation – which is associated with an increased lifetime risk of cancer, according to Stenzel.

“It is especially important to avoid subjecting children to diagnostic tests that use ionizing radiation because children have many years to live and the risk of cancer is cumulative,” Stenzel said. “In addition, we do not know how ionizing radiation may affect future reproductive capacity or the impact it may have on their unborn children.”

Stenzel said that since CEUS images are not jeopardized by patient movement, the technique is particularly suitable for imaging young patients who will not lay still. “This avoids the need for sedating children prior to imaging,” he said.

New Ultrasound Technique Helps Identify Patients Who Need Breast Biopsies

A new ultrasound technique is proving valuable in distinguishing malignant from benign breast lesions in some patients – results that could mean fewer unnecessary breast biopsies, a new study shows.

The study found that ultrasound elastography, which indicates tissue softness, can help predict cancer in patients with BI-RADS category 4 masses. “Because malignant tumors predominantly are harder than benign tissues, this technique significantly improves the differentiation between benign and malignant tissue” said Hiroko Satake, MD, lead author of the study. Dr. Satake is from Nagoya University School of Medicine in Japan.

“In an analysis of 115 breast masses that were recommended for biopsy (they were categorized as either BI-RADS 4 or BI-RADS 5), ultrasound elastography was 79% accurate in identifying cancer,” Dr. Satake said.

“By accurately identifying benign tumors with imaging, we may be able to avoid sending patients for unnecessary biopsies,” Dr. Satake said. Ultrasound elastography provides radiologists with elasticity scores, with lower scores meaning that the mass contains softer tissue. “Based on the results of our study, we recommend that patients with BI-RADS 4 masses should undergo biopsy if their ultrasound elasticity score is 4 or 5,” Dr. Satake said.

Accurate diagnosis of prostate cancer with ultrasound

Prostate cancer is the most common type of cancer among men, but its diagnosis has up to now been inaccurate and unpleasant. Researchers at TU/e, in cooperation with AMC Amsterdam, have developed an imaging technology, based on ultrasound, that can accurately identify tumors. The technology also has the potential to assess how aggressive tumors are. This can lead to better and more appropriate treatment, and to cost savings in health care.

The new technology uses the injection of microbubbles of a contrast agent with no side-effects. The response of the tiny bubbles to ultrasound is different from that of human tissue or blood. This makes the bubbles traceable from the outside, right into the smallest blood vessels. The pattern of blood vessels in tumors is different from that in healthy tissue. The researchers can recognize this pattern from advanced analysis of the bubble concentrations. And because tumors need blood – and hence new blood vessels – to grow, the researchers expect to be able to see how aggressive the cancer is from the pattern of the blood vessels.

U-Systems Announces Initiation of European Breast Ultrasound Screening Study

SUNNYVALE, Calif.--(BUSINESS WIRE)--U-Systems, the leader in Automated Breast Ultrasound (ABUS) technology announced participant enrollment has begun in the European Asymptomatic Screening Study (EASY) at Capio Saint Göran Hospital, in Stockholm, Sweden. The clinical study is designed to determine whether Full Field Digital Mammography combined with the somo•v® Automated Breast Ultrasound (ABUS) can improve breast cancer detection when compared to Mammography alone in women with dense breast tissue. This study is particularly relevant to the many population based screening programs in Europe which practice a double-reading methodology for screening, where two different radiologists independently review breast imaging exams. The study protocol has accommodated the standard screening practices in Sweden and outlined a process for integrating ABUS review into an existing double-read system.


Screening mammography, the mainstay for breast cancer detection, has known limitations in women with dense breast tissue and these women have a higher risk of breast cancer. A new approach is needed to improve breast cancer detection for women with increased breast density. The EASY breast cancer screening study will help determine if using this 3D ultrasound imaging technology in combination with a digital mammogram could improve the accuracy of routine screenings for women with dense breast tissue, for which mammography can be less effective. The study intends to recruit 8,000 asymptomatic women with dense breast tissue.
