Rare fossil reveals weird early tree
The earliest trees, from nearly 400 million years ago, are known mostly from fossils of their trunks; their leaves and canopy shapes have remained a mystery. A newly reported, 350-million-year-old tree found in Canada provides a vivid answer for one such primordial species: As if having a perpetual bad hair day,
a thick crown of spiky leaves stuck out perpendicularly from the trunk
. Scientists named the tree
Sanfordiacaulis densifolia
, after the owner of the New Brunswick quarry where they found five specimens. The fossils, amo...

You May Not Need a Lead Apron for a Dental X-ray, a New Recommendation Says
Those heavy lead aprons may be on their way out at the dentist office, depending on where you live.
The nation’s largest dental association said Thursday it will no longer recommend the use of lead aprons and thyroid collars on patients who are getting dental X-rays.
There are two main reasons for the change. X-ray beams are now more focused, so there is less concern about radiation hitting other parts of the body. Also, the aprons and collars can sometimes block dentists from getting the images they need.

The best thing to lower radiation exposure is to make sur...

Dental Group Says Lead Aprons No Longer Needed for X-Rays
FRIDAY, Feb. 2, 2024 -- The heavy lead apron dentists drape over you during dental X-rays may soon be a thing of the past.
On Thursday, the American Dental Association (ADA) announced that its member dentists can dispense with the aprons,... (Source: Drugs.com - Daily MedNews)

BERT-based AI poised for use in radiology
AI models based on Google’s BERT are poised to play a pivotal role in radiology, according to a review published January 30 in the Journal of the American College of Radiology.
In an analysis of 30 studies, researchers found that BERT has been successfully harnessed primarily for classification tasks and extracting information from radiology reports, noted lead author Larisa Gorenstein, MD, of Tel Aviv University in Israel, and colleagues.
“As BERT technology advances, we foresee further innovative applications. Its implementation in radiology holds potential for enhancing diagnostic precision, expediting report gene...

Using deep learning with CT helps predict hip fractures
A deep-learning model that includes digital x-rays reconstructed from 3D hip CT images shows promise for predicting subsequent fractures in patients with a relatively recent hip break, researchers have found.
The findings could improve how clinicians care for their patients, wrote a team led by doctoral candidate Yisak Kim of Seoul National University Graduate School in South Korea. The group's findings were published January 30 in Radiology.
"Developing a prediction model for short-term subsequent fracture risk is important because it would identify patients at the highest risk and aid in determining appropriate treatme...

AI improves performance of nonradiologists in chest imaging
AI improves chest x-ray imaging interpretation by nonradiologist practitioners, which could be useful in low-resource settings, according to research published January 29 in Chest.
A team led by Jan Rudolph, MD, from University Hospital, LMU Munich in Germany found that a convolutional neural network (CNN)-based AI system focusing on chest x-rays improved the performance of nonradiologists in diagnosing several chest pathologies.
“In an emergency unit setting without 24/7 radiology coverage, the presented AI solution features an excellent clinical support tool to nonradiologists, similar to a second reader, and allows ...

X-rays show nighttime bracing may be effective for scoliosis patients
Nighttime bracing may be an effective alternative to full-time bracing in patients with adolescent idiopathic scoliosis, according to a study published January 29 in JAMA Network Open.
In a clinical trial in Sweden, researchers measured Cobb angles on x-rays in participants using the strategy combined with physical activity and found the intervention prevented spinal curve progression, noted lead author Anastasios Charalampidis, MD, PhD, of the Karolinska Institutet in Stockholm, and colleagues.
“While longer hours of full-time brace wear have been shown to be superior to observation in terms of preventing curve progre...

‘Lobster eye’ in space promises new look at x-rays
China last week launched an x-ray observatory with an unusual telescope inspired by the structure of lobster eyes to gather new data on gamma ray bursts, supernovae, and stars being swallowed by black holes. The Einstein Probe (illustration above)—a joint project of the Chinese Academy of Sciences, the European Space Agency, and the Max Planck Institute for Extraterrestrial Physics—will also capture x-rays from violent events that generate gravitational waves, such as two neutron stars colliding. The telescope features a survey inst...

How much do canceled appointments actually cost radiology?
Brian Bradfield.Canceled appointments are an inevitable part of a radiology department's — and a hospital's — operations. As shown in an MGMA Stat poll
Looking at this through the lens of financial health, this increase in no-shows translates into a big profit hit for radiology. It's more than the loss of revenue from delivered services — it's also a matter of underutilization of resources.
Loss of provided service revenue
Radiology services can be a big profit generator for hospitals. As the population ages and preventive measures become more commonplace, there is a heightened demand for CT scans, MRIs, and x-ra...

AI may help plan new treatment in scoliosis patients
An AI model for x-ray imaging could help clinicians plan treatment other than spinal fusions in patients with adolescent idiopathic scoliosis, according to research published January 14 in PLOS One.
The study proposes a machine learning-based tool for planning anterior vertebral body tethering (AVBT), an emerging minimally invasive surgical treatment, noted first author Ausilah Alfraihat, a PhD student at Drexel University in Philadelphia, PA, and colleagues.
“The current model has potential to serve as a valuable clinical tool, providing insight into the optimal timing of intervention and surgical planning parameters,...

Radiologists in Europe ramp up testing of AI
Four out of seven commercially available AI algorithms for detecting lung nodules on x-rays performed better than human readers, while two algorithms for predicting bone age fell short, in a study published January 9 in Radiology.The study validates the methodology of an initiative called Project AIR, which the researchers developed to standardize testing of AI radiology products cleared for use in Europe, noted lead author Kicky van Leeuwen, a doctoral candidate at Radboud University in Nijmegen, the Netherlands, and colleagues.“Clinical centers rarely have the necessary resources and personnel to evaluate and compare m...

Inside the Nuclear Fusion Facility That Changed the World
Shortly after 1 a.m. on the morning of Dec. 5, 2022, Dave Schlossberg, an experimental physicist at National Ignition Facility (NIF), was woken by a phone call. A fusion experiment using NIF’s massive lasers was scheduled to go off that night. Going to bed a few hours earlier, he had told Alex Zylstra, one of the physicists on his team, to call him “if anything interesting happens.” Now Zylstra was seeing data unlike anything the facility had registered before. They seemed to show that the scientists had achieved a monumental step in a decades-long quest to replicate the energy source that powers the sun....
