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.

The fall and rise of trauma CT on the front and back of COVID-19

When COVID-19 social-distancing orders eased across a densely populated county in the southwest, trauma visits spiked 35% over the pre-pandemic normal. This was accompanied by a 17% increase in average daily trauma CT exams.

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.

Advances in computed tomography scanner (CT) technology include photon-counting (Siemens image left) and faster, higher slice CT systems with integrated AI. Right image is GE Healthcare's Revolution on display at SCCT 2022. Trends in CT imaging by Signify Research.

Can standard radiation treatments replace surgery for some breast cancer patients?

As chemotherapy treatments improve, patients who respond well may be able to skip surgery with a low chance of recurrence.

X-rays may suffice for assessing some low-back fractures

It’s unlikely radiography will unseat MRI for routinely distinguishing between acute and chronic compression fractures of the lumbar vertebrae, but certain X-ray findings might, in cases, obviate the need for the pricier imaging option.
