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.

Pelvic CT after liver cancer: Costs versus benefits

Should patients treated for hepatocellular carcinoma undergo regular follow-up pelvic CTs? Rising survival rates may change the calculus.

Proposed bills in several states would bolster coverage for breast imaging services

The Susan G. Komen organization has lobbied for the proposals and recently touted them in a series of separate announcements.

MRI catches CT in head-to-head lung imaging

When it comes to assessing patients with suspected pulmonary embolism, contrast-enhanced CT pulmonary angiography has no diagnostic edge over a certain free-breathing, unenhanced MRI perfusion protocol.

0.55T MRI lumbar compared to 1.5T sequence #lumbarMRI #1.5T

Low-field MRI systems improve accessibility, but what kind of diagnostic quality do they offer?

Experts recently compared the use of a 0.55T low-field MRI system to a 1.5T system to determine whether the results rendered were within an acceptable diagnostic range.

Fatal accident calls MRI safety standards into question—are more regulations needed?

There are a number of well-intended recommendations for preventing MRI injuries, but many of them stop short of implementing safety requirements.

Mammography guideline changes have produced a ‘harmful’ spillover effect

Mammography screening trends had remained flat, but they fell across all age groups after the USPSTF issued new guidelines in 2009.

Mediolateral oblique view from a screening mammogram in a 54-year-old woman shows a small cluster of microcalcifications in the upper outer quadrant of the right breast. The right image shows a detailed spot magnification view of the calcifications. Stereotactic biopsy revealed grade 2 ductal carcinoma in situ (DCIS). RSNA image. Image of breast micro calcifications associated with breast cancer.

Why the way microcalcifications on mammograms are regarded could change

New research suggests that the tissue environment where microcalcifications of the breast are formed could hold clues into how breast cancer progresses.

Focused ultrasound reduces physical symptoms of Parkinson's disease

Given the less invasive nature of focused ultrasound procedures, researchers suggest that it could open the door for disease management options catered to a wider variety of patients.
