3D Printed “Edge Detector” Can Sort Soundwaves
This type of measuring method delivers similar results to the edge detection filter in an image-processing software, which allows the outline of prominent photo objects to be identified with the click of the mouse.
Ultrasound for Infants at Risk for Developmental Dysplasia of the Hip
Selective ultrasound screening may be effective in infants with risk factors and normal findings on physical examination. Selective ultrasound screening changed treatment management in almost 8% of patients and clinical follow-up in 6.5%. Analysis of the cost-effectiveness of screening is needed.
CEUS Shows Effectiveness of Cancer Therapy in Children
A new study shows that contrast-enhanced ultrasound (CEUS) imaging can help predict whether children with cancer will respond favorably to certain cancer drugs that target and destroy tumor blood vessels, according to physicians at St. Jude Children's Research Hospital in Memphis.
Freehand versus guided techniques for renal biopsy compared
The study found that when using a 14G needle, there is higher risk of minor complications in the free hands-(ultrasound-assisted) technique compared to the ultrasound-guided technique but no differences between techniques when using a 16G needle.
Ultrasound Image 3D bone segmentation shows clinical promise
Researchers are closing in on a radiation-free alternative to intraoperative fluoroscopy in orthopaedic surgery. A newly validated algorithm delivers clear bone surface images in near real-time from ultrasound images, according to a recently puglished study.
Ultrasound-detected Tenosynovitis May Predict Rheumatoid Arthritis
Using an ultrasound to predict tenosynovitis may also predict early rheumatoid arthritis (RA), according to the results of a study presented at the European League Against Rheumatism Annual Congress (EULAR 2015) Press Conference in Rome, Italy earlier this summer.
Tool tracks brainwaves, blood flow in moving rats
A head-mounted device uses ultrasound to measures blood flow and EEG to measure electrical activity in the brains of rats as they roam their cages. The device, described 3 August in Nature Methods, may help researchers understand how brain activity goes awry in autism.
Ultrasound, MRI Comparable for Cervical Cancer Staging
Transvaginal sonography, performed by a dedicated gynecologic radiologist, is comparable to magnetic resonance imaging for diagnosing and staging local cervical cancer, according to a study published online Aug. 21 in the Journal of Clinical Ultrasound.
