New Women's Imaging Technique Allows for a More Accurate Diagnosis of Breast Cancer
April 24, 2009Breast elastography allows physicians to give a more accurate diagnosis of breast cancer, according to a study performed at Singapore General Hospital in Singapore. Breast elastography is a new technique which looks at the mechanical properties of tissues (relative stiffness) as opposed to conventional ultrasound which looks at the backscatter of transmitted ultrasound waves through tissues.
Ninety-nine women with 110 sonographically visible lesions were evaluated with ultrasound, elastography and combined ultrasound and elastography. 26 lesions were malignant and 84 were benign on histology. "All breast cancers (100%) in the study were diagnosed correctly by elastography alone compared to 88.5% by conventional ultrasound," said Llewellyn Sim, MD, lead author of the study. "The use of breast elastography alone or combined with ultrasound provides a more accurate diagnosis of breast cancer," said Dr. Sim.
"Breast elastography improves the sonographic diagnosis of breast cancer. It also potentially reduces unnecessary work-up i.e. biopsies of benign breast lesions and patient anxiety," he said.
"Breast radiologists will see elastography in a different light when they realize that it has come of age and outperforms conventional breast ultrasound. With the sterling results and knowledge gained from my study, I am more confident in using elastography to assist me in obtaining a more accurate diagnosis of breast lesions detected with ultrasound in my daily clinical practice," said Dr. Sim.
This study will be presented at the 2009 ARRS Annual Meeting in Boston, MA, on Wednesday, April 29. For a copy of the full study, please contact Heather Curry via email at hcurry@arrs.org.
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.

Elastography Current Events and Elastography News RSSProbe position may change results in liver stiffness measurements in transient elastography
A major clinical challenge is to find the best method to evaluate and to manage the increasing numbers of patients with chronic liver disease. Liver biopsy, due to its risks and limitations, is no longer considered mandatory as the first-line indicator of liver injury, and several markers have been developed as non-invasive alternatives.
Can EUS elastography help distinguish benign from malignant tissue?
A major limitation of endoscopic ultrasound (EUS) examination is its limited capacity to determine the exact nature of a lesion.
Mayo Clinic's new imaging technology accurately identifies a broad spectrum of liver disease
A new study shows that an imaging technology developed by Mayo Clinic researchers can identify liver fibrosis with high accuracy and help eliminate the need for liver biopsies. Liver fibrosis is a common condition that can lead to incurable cirrhosis if not treated in time.
Noninvasive test accurately identifies advanced liver disease without biopsy
Non-invasively measuring liver stiffness with transient elastography accurately diagnoses patients with late-stage liver disease, reports a new study in Clinical Gastroenterology and Hepatology, the official journal of the American Gastroenterological Association (AGA) Institute.
MRE could provide a definitive diagnosis for people with muscle pain, Mayo Clinic study shows
An estimated nine million men and women in the United States live with myofascial pain syndrome, a condition marked by pain that permeates muscles in the neck, back and shoulders.
Noninvasive tests for cirrhosis may help to avoid liver biopsy
Newer ultrasound and magnetic resonance (MR) imaging tests yield encouraging initial results in diagnosing fibrosis (scarring) and cirrhosis of the liver, according to three studies in the October issue of the journal Clinical Gastroenterology and Hepatology.
New Mayo Clinic MRI technology enables noninvasive liver diagnoses
Two recent Mayo Clinic studies have found that magnetic resonance elastography (MRE), a new imaging technique invented at Mayo Clinic, is an accurate tool for non-invasive diagnosis of liver diseases.
Liver diagnosis breakthrough with Mayo Clinic MRI development
Mayo Clinic researchers have developed a new technique for using magnetic resonance imaging (MRI) to accurately measure the hardness or elasticity of the liver. First tests show this technology - called MR Elastography (MRE) - holds great promise for detecting liver fibrosis, a common condition that can lead to incurable cirrhosis if not treated in time.

Elastography: Webster's Timeline History, 1983 - 2007 by Icon Group International (Author) Webster's bibliographic and event-based timelines are comprehensive in scope, covering virtually all topics, geographic locations and people. They do so from a linguistic point of view, and in the case of this book, the focus is on "Elastography," including when used in literature (e.g. all authors that might have Elastography in their name). As such, this book represents the largest compilation of timeline events associated with Elastography when it is used in proper noun form. Webster's timelines cover bibliographic citations, patented inventions, as well as non-conventional and alternative meanings which capture ambiguities in usage. These furthermore cover all parts of speech (possessive, institutional usage, geographic usage) and contexts, including pop culture, the arts, social... |

Ultrasonic elastography of porcine coronaries: High frequency ultrasonic elastography measurements of the mechanical properties of porcine coronary vessel walls by Veerdhaval Mahajan (Author) Coronary heart diseases are a significant cause of death among both men and women in the industrialized world. Thus finding ways to detect factors, which cause coronary heart diseases, is a worthy challenge for researchers. Ultrasound elastography system (50MHz) for measuring mechanical properties of arteries was developed as part of this thesis. Ability to discriminate between various tissue types was demonstrated using fresh and modified porcine coronary arteries, which closely models the plaque in human atherosclerosis. Elastographic measurements agreed well with uniaxial mechanical testing over a range of compression moduli. |
