Medical Imaging

Physicians utilize medical imaging to see inside the body to diagnose and treat patients. This includes computed tomography (CT), magnetic resonance imaging (MRI), X-ray, ultrasound, fluoroscopy, angiography,  and the nuclear imaging modalities of PET and SPECT.

New PET technique spots 'smoldering' changes not visible on MRI in the brains of MS patients

The new technique uncovers hidden inflammation in patients who, despite undergoing extensive treatment for the condition, had worsening symptoms.

Rad techs helpfully ‘stand in a surgeon’s shoes’ thanks to virtual reality

Johns Hopkins researchers demonstrated the worthiness of the concept this year.

ChatGPT shows 'significant promise' in guiding contrast-related decisions

This could be especially helpful when timely clinical decisions relative to the use of a contrast agent need to be made.

Actionable tips imaging departments can implement to reduce energy consumption

With the earth’s warmest March on record in 175 years barely in the rearview mirror, a team of radiology experts says medical imaging must step up its sustainability efforts. 

Advanced artificial intelligence (AI) models can evaluate cardiovascular risk in routine chest CT scans without contrast, according to new research published in Nature Communications.[1] In fact, the authors noted, the AI approach may be more effective at identifying issues than relying on guidance from radiologists.

AI predicts cardiovascular risk during CT scans—no invasive tests or contrast required

Two advanced algorithms—one for CAC scores and another for segmenting cardiac chamber volumes—outperformed radiologists when assessing low-dose chest CT scans.

IAEA: When selecting medical imaging equipment, don’t assume ‘new’ means ‘low dose’

Advanced imaging equipment using ionizing radiation enters the global market at the rate of one new technology every five years.

Blood test could help cut back on head CTs in patients with blunt trauma

Given the subjective nature of diagnosing concussions, it can be difficult to make the call on whether a patient needs imaging, but many doctors err on the side of caution.

Image Wisely rolls out new MRI safety course following slew of accidents

The course’s release follows numerous reported MRI accidents that have occurred in recent years, many that resulted in severe injury and some that were even fatal.

Around the web

A total of 16 cardiology practices from 12 states settled with the DOJ to resolve allegations they overbilled Medicare for imaging agents used to diagnose cardiovascular disease. 

CCTA is being utilized more and more for the diagnosis and management of suspected coronary artery disease. An international group of specialists shared their perspective on this ongoing trend.

The new technology shows early potential to make a significant impact on imaging workflows and patient care.
