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.

'Desktop' MRI brings physics education to the classroom

The tabletop scanner provides students with more hands-on opportunities to learn about the processes that drive the modality’s imaging capabilities.

MRI-first approach could allow many to safely forego prostate biopsy

New findings indicate as many as 96% of men with positive PSA labs who show insignificant or slow-growing cancer on MRI can safely forego biopsy for three or more years.

U.S. moves closer to establishing domestic supply of Mo-99 for nuclear imaging

Society of Nuclear Medicine and Molecular Imaging President, Cathy Cutler, explains the long road to jump-starting a new U.S. domestic supply of imaging isotopes.

Repurposed radiotracer lights up treatment-resistant tumors 'like a Christmas tree'

Use of the new tracer could improve outcomes by enabling providers to adjust treatment regimens much earlier than they have been able to previously.

New algorithm is twice as accurate at predicting stroke timing compared to the standard of care

Determining stroke onset is critical for management, as there is a small window of time for initiating treatment that can inhibit damage.

Kate Hanneman, MD, chair of the Radiological Society of North America (RSNA) program planning committee, explains some of the key trends she saw in sessions during RSNA 2024. #RSNA #RSNA24 #RSNA2024

RSNA 2024 Program Chair Kate Hanneman highlights key trends in radiology

The cardiac radiologist and associate professor at the University of Toronto offered insights into key themes from the conference. 

New protocol addresses contrast allergies in patients with suspected stroke

In patients with suspected stroke, contrast allergies present a significant dilemma, as contrast-enhanced imaging is often used to guide treatment decisions.

For the first time, researchers find a way to spot early signs of pancreatic cancer on routine MRI

Pancreatic cancer is one of the deadliest cancers, with a five-year survival rate of only 44% if caught early, dropping down to 3% if it metastasizes. This is largely due to its ability to elude detection.

Around the web

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. 

Richard Heller III, MD, RSNA board member and senior VP of policy at Radiology Partners, offers an overview of policies in Congress that are directly impacting imaging.
