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.

How the shape, size and location of calcified carotid plaques affect stroke risk
A new analysis provides further insight into factors affecting plaque stability and subsequent ischemic events
FDA approves expanded use of PET imaging agent
The product's updated indications include quantification and long-term monitoring of amyloid plaques on imaging.
Low dose GBCA effective, safe for pediatric imaging
Although gadopiclenol is approved for adults and children ages 2 and older, there is limited data on its use in the pediatric population.
'Powerful' new PET agent improves the diagnosis of triple-negative breast cancer
The agent “exhibits powerful tumor delineation” in challenging cases of determining cancer subtypes, and could potentially lead to more personalized, effective treatment strategies.
Emergency physicians make more mistakes when interpreting imaging of multiple organs
A new analysis details the prevalence of interpretation errors in EDs, the factors that influence them and how they affect patient care.

Body CT scans detect infection areas among ICU patients with sepsis

While guidelines stress the importance of quickly eradicating the underlying source of infection, data on the best imaging strategy remains lacking, researchers reported.

Radiologists prefer MRI over ultrasound for pregnant women with suspected appendicitis

The findings may be particularly important in settings where subspecialty radiologists are not as readily available, experts wrote recently.

Artificial intelligence could pinpoint success of rectal cancer treatment based on routine MRI

The Department of Defense is gifting Case Western researchers a grant to study the use of AI in determining whether patients require surgery.

The algorithm yielded a 94.4% accuracy for labeling arteries in accordance with the Society of Cardiovascular Computed Tomography guidelines.

New CT protocol uses scout images to expedite stroke patients' path to MRI

The new safety screening protocol should "markedly improve" current delays in screening patients, Mayo Clinic doctors explained.

Subspecialty radiologists disagree with non-specialists’ incidental nodule guidance in 38% of cases

Thoracic experts' re-reading of CT scans initially performed in the ED often resulted in additional imaging utilization.

Brain MRI volumes dip but acuity leaps, with implications for radiologist staffing

More complicated exams could require additional physician time and effort, Emory University experts detailed in Current Problems in Diagnostic Radiology.
