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.

Shoulder ultrasound effectively detects insulin resistance, even before abnormal labs
POCUS could represent a quick, easy and affordable way to detect signs of insulin resistance before it progresses into diabetes, researchers suggest.
Contrast-enhanced mammography significantly improves early cancer detection
New trial results suggest CEM could enhance breast cancer detection beyond DBT exams when patients are faced with barriers to obtaining an MRI.
Bayer seeks FDA approval for gadoquatrane, its latest low-dose GBCA
The investigational agent uses 60% less gadolinium without sacrificing image quality, according to recent clinical trial findings.
ChatGPT's medical advice may be deterring women from necessary imaging
The LLM’s responses may be misleading in certain situations, which could pose problems for patients who trust the medical advice it provides.
Tau tangles on PET scans may signal impending cognitive decline in asymptomatic individuals
New data highlight the significance of tau-positive imaging in the progression of Alzheimer’s disease.

Many U.S. websites do not reflect updated lung cancer screening guidelines

Accurate information relative to personal risk is crucial for improving uptake of low-dose CT (LDCT) lung cancer screening, but new data indicate that many websites' content on the topic is out of date.

Example of the four types of breast tissue density. The density of fibroglandular tissue inside the breast impacts the ability to easily see cancers. Cancers are very easy to spot in fatty breasts, but are almost impossible to find in extremely dense breasts. These examples show craniocaudal mammogram findings characterized as almost entirely fatty (far left), scattered areas of fibroglandular density (second from left), heterogeneously dense (second from right), and extremely dense (far right).

Breast density notification laws: How will the FDA's updates affect radiologists and referring providers?

The FDA will soon require mammography providers to inform all patients of their breast density status. To anticipate how the update might affect key stakeholders, it’s important to understand exactly what has changed.

Neuroradiologists make more mistakes when facing these 3 scenarios

“These findings should be considered when designing workflow-related and other interventions seeking to reduce errors," experts wrote in AJR.

MRI protocol tweak nets big savings for hospital system while opening up additional exam slots

An inordinate number of patients with metallic hardware were receiving inappropriate MRIs without a key sequence to reduce related artifacts.

Paltry use of CT for lung cancer screening persists across all payer types

The findings should serve as a call to action for radiologists to increase awareness about LDCT, experts contended.

Even in asymptomatic, CCTA-detected coronary artery disease increases heart attack risk

These individuals face a more than an eightfold risk for myocardial infarction, according to new findings published in the Annals of Internal Medicine.
