Diagnostic Imaging

Radiologists use diagnostic imaging to non-invasively look inside the body to help determine the causes of an injury or an illness, and confirm a diagnosis. Providers use many imaging modalities to do so, including CT, MRI, X-ray, Ultrasound, PET and more.

Hantavirus on imaging: What radiologists need to know
Two months after a cluster of cases occurred on a cruise ship, experts are offering insight into how radiologists can help spot the "silent" signs of the deadly virus on imaging.
Simple measurement from routine X-rays accurately predicts post-op lung cancer outcomes
For the first time, research has identified diaphragmatic dome height measured on chest X-rays as an indicator of what patients’ post-op recovery will look like following surgery for cancer or other lung disorders.
High-sensitivity troponin protocol most successful at freestanding EDs
Freestanding EDs demonstrated meaningful operational advantages over hospitals when using an accelerated troponin pathway. This included earlier discharges for low-risk chest pain patients.
FDA clears Qure.ai's CAD tool for chest X-rays
The product is used to highlight findings from plain chest radiographs completed in emergency departments, urgent care clinics and family practices.
Cardiologist discusses Lp(a), the CVD risk factor responsible for many surprise heart attacks
Cardiologist Nathaniel Lebowitz, MD, reviews the latest updates in lipoprotein(a) awareness, testing and drug development.

Can scatter correction software replace physical grids?

The clinical application of scatter correction software is limited by numerous factors, according to a new analysis.

Bruce Haffty, MD, president of Radiological Society of North America (RSNA) Board of Directors, chair of radiation oncology, associate vice chancellor for cancer programs at Rutgers Cancer Institute of New Jersey and system director of radiation oncology at RWJBarnabas Health, discusses the president’s address "Diagnostic Imaging: Value From the Lens of the Patient," with Radiology Business. Haffty will present his opening session at RSNA 2022 at 4 p.m., Nov. 27, 2022, in the Arie Crown theater.

Haffty offered his perspective on the conference as a whole and previewed his presidential address, which is scheduled for early Sunday evening.

The Nanox ARC cold-cathode, tomosythesis 3D X-ray system is currently pending FDA clearance. If cleared, it would be the first device of its kind to offer cold-cathode X-ray tube technology and the ability to slice through the anatomy in images similar to CT scans aid diagnosis. The new type of tube also could greatly reduce the size and weight of X-ray systems. The vendor sees this system as key to its larger plan to address health disparities and access to imaging world-wide. #Nanox

Can cold-cathode X-ray combined with teleradiology and AI eliminate health disparities?

The Israeli vendor Nanox says it has a vision for the future of healthcare. It seeks to address health disparities and access challenges with a new business model and innovative package of technologies. Hurdles loom, but opportunities abound.

VIDEO: The many benefits of spectral CT for cardiovascular imaging

Suhny Abbara, MD, editor of Radiology: Cardiothoracic Imaging and chief of cardiothoracic imaging for University of Texas Southwestern Medical Center, discusses how spectral computed tomography (CT) can help both cardiac and general CT imaging.

Chest X-rays alone ineffective in COVID triage

New research indicates that there is significant reader variability in COVID classifications among different specialties when chest X-rays alone are the diagnostic tool of choice.

Top MRI trends include helium-free systems, compressed sensing and AI

Signify Research outlines several key technologies and trends in MRI to look for at the Radiological Society of North America 2022 meeting.

New DL model detects effects of long COVID using only x-rays

The model could be beneficial for long COVID patients in areas where CT scans are not readily available, researchers concluded.

A GE Revolution CT system on display at the 2022 Society of cardiovascular Computed Tomography (SCCT) meeting is an example of the types of the systems being sought in the U.S. and Western Europe replacement CT market. It features AI enhanced features to automate protocol and help reduce dose, 160 mm of anatomical coverage per rotation and offers spectral imaging using fast kV switching between different energies during one scan.

Trends and new technology in computed tomography systems

Leading up to the 2022 RSNA meeting, Signify Research shares the trends and new innovations in CT scanner technology it has seen in recent years.
