Magnetic resonance elastography may be a viable alternative to detecting liver fibrosis in children.
MR elastography is the preferred method for assessing liver stiffness and is growing in availability. Here’s the background, benefits, and future of this nascent modality.
Ultrasound-based transient elastography provides excellent diagnostic accuracy in identifying cirrhosis due to recurrent hepatitis C following liver transplantation.
Ultrasound elastography is shown to raise sensitivity by 24 percent for preoperative assessment of axillary metastases in suspected breast cancer. Meanwhile, microbubbles identify sentinel lymph nodes, minimizing operations, according to researchers presenting at ECR 2011.
Dr. Ellen Mendelson is a co-author on a paper exploring the use of shear wave elastography to distinguish between benign and malignant lesions. In an interview with Diagnostic Imaging, she explains what shear wave elastography is and why it could become a standard element of breast imaging.
Radiation safety standards are becoming increasingly stringent. Ultrasound systems, however, present no such safety threats, and manufacturers are trying to enhance the versatility of these devices, both in primary and secondary diagnosis. Elastography and therapeutic and contrast-enhanced ultrasound are poised to herald new and more effective means of diagnosis.
Reducing the number of breast biopsies by better classifying suspicious lesions noninvasively could improve healthcare and cut healthcare costs, laudable goals in the current era of healthcare—and economic—reform.
A new ultrasound technique that measures cell death, tumor elastography, and vascular patterns can better predict how well cancer patients are responding to chemotherapy, Canadian researchers report.
Adding strain ratio measurement to ultrasound elastography would provide a more objective way to differentiate benign from malignant breast lesions than a five-point scoring system now being used, according to a study presented at the European Congress of Radiology in March.
The exhibition booths occupied by vendors of ultrasound systems at ECR 2010 are likely to be very busy places throughout the congress. Difficult economic conditions are causing a dip in global demand for the more capital-intensive modalities like CT and MRI, and hospital managers are keen for their staff to explore the clinical potential of this versatile and cost-effective technology.
