US surveillance of HCC subject to image quality issues
May 21, 2015 -- Ultrasound may be the imaging modality of choice for surveillance of hepatocellular carcinoma (HCC) in high-risk patients, but variance in exam quality can be a big problem, according to researchers from the University of California, San Diego.
Sonography students sue college over transvaginal exams
May 19, 2015 -- Two former sonography students have filed a lawsuit against a college in Florida, alleging that the institution and employees in its medical diagnostic sonography program retaliated against them after they protested against having to undergo transvaginal ultrasound procedures as part of their sonography training.
Contrast US flexes muscle against gallbladder disease
May 13, 2015 -- Early detection is important for all cancers, but it's particularly crucial for the often-deadly gallbladder carcinoma. Contrast-enhanced ultrasound can be a useful weapon in the battle to diagnose gallbladder cancer sooner, according to researchers from China.
Point-of-care ultrasound can assess soft-tissue neck masses
May 8, 2015 -- Point-of-care ultrasound is a valuable tool for pediatric emergency medicine physicians evaluating soft-tissue masses in the neck, outperforming clinical assessment, according to a pilot study from Maimonides Medical Center in New York City.
No need for CT: Contrast US can follow up solid-organ injuries
April 30, 2015 -- Contrast-enhanced ultrasound (CEUS) can be used in favor of CT for following up solid-organ injuries in children and young adults, avoiding unnecessary radiation exposure in this vulnerable population, according to researchers from King's College Hospital in the U.K. who reported their findings from a large retrospective study.
Congenital heart disease detected less often in rural areas
April 28, 2015 -- Ultrasound may be doing a better job overall of diagnosing critical congenital heart disease prenatally, but that's not necessarily the case in poorer and more rural communities, according to research presented on Monday at the Pediatric Academic Societies annual meeting in San Diego.
Bedside ultrasound can diagnose acute shoulder dislocation
April 24, 2015 -- Patients presenting to the emergency department with acute shoulder pain typically receive an x-ray exam. However, ultrasound can provide equivalent performance -- often in less time and without the ionizing radiation -- for diagnosing shoulder dislocation, according to researchers from the University of California, Irvine.
Teleradiology prompts shift in use of after-hours ultrasound
April 14, 2015 -- Researchers in France found that concerns over who would perform after-hours emergency ultrasound scans shouldn't be a roadblock for hospitals that want to implement an overnight teleradiology service. They found that all but 14% of scans could either be replaced or postponed.
Coregistered 3D US plus angio boosts aneurysm surgery
April 6, 2015 -- Combining rotational digital subtraction angiography with 3D ultrasound creates a powerful pair for guiding aneurysm surgery when images are dynamically coregistered during procedures, according to a new study by German researchers and published in PLOS One.
Practice of Ultrasound: Part 22 -- Quantum ultrasonics
April 3, 2015 -- In the next installment of his series on the practice of ultrasound, Dr. Jason Birnholz delves into the quantum energy foundations of ultrasound, providing a fundamental link to all other diagnostic imaging techniques.
