Researchers Develop New and Efficient Breast Biopsy Technique

25.06.2009
Researchers have developed a new breast biopsy technique that could lead to decreased procedure times and reduced patient discomfort and morbidity, according to a study performed at Roberts Research Institute, the University of Western Ontario and London Health Sciences Centre, London, ON, Canada. The new technique uses a mechanical arm to guide the needle for the biopsy and has a braking system to allow for accurate placement of the needle and to avoid needle motion.

Breast biopsy procedures, using both methods, were performed on phantoms during the study. “Our results showed that biopsy success rates were greater when using our new guidance system,” said Aaron Fenster, MD, lead author of the study.

“We also showed that experienced and inexperienced radiologists performed a biopsy significantly faster when using our needle guidance system,” said Dr. Fenster. The success rate using the needle guidance system was 95.9% compared to a success rate of 91.3% using the freehand technique.

Using the freehand technique, experienced radiologists had a procedure time of approximately 31 seconds. Using the needle guidance system, experienced radiologists had a procedure time of approximately 10 seconds.

“Techniques for improving biopsy procedures are needed to make the procedures more efficient and reduce the variability due to physician experience and size of the target lesion. Breast biopsy using the developed needle guidance system is feasible and I believe it will enable physicians to diagnose early-stage carcinomas more efficiently and accurately, thus decreasing patient morbidity,” said Dr. Fenster.

“The system we designed is a prototype and is required to be redesigned for routine clinical use. Tests with human subjects are planned for the fall of 2009,” he said.

About ARRS

The American Roentgen Ray Society (ARRS) was founded in 1900 and is the oldest radiology society in the United States. Its monthly journal, the American Journal of Roentgenology, began publication in 1906. Radiologists from all over the world attend the ARRS annual meeting to participate in instructional courses, scientific paper presentations and scientific and commercial exhibits related to the field of radiology. The Society is named after the first Nobel Laureate in Physics, Wilhelm Röentgen, who discovered the x-ray in 1895.

Im Focus: Data use draining your battery? Tiny device to speed up memory while also saving power

The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.

Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

Im Focus: Lethal combination: Drug cocktail turns off the juice to cancer cells

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.

The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...

Im Focus: New Foldable Drone Flies through Narrow Holes in Rescue Missions

A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.

Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
