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.

Breast cancer screening rates saw a 10% drop among several groups of women over the last 2 decades
Decreased screening rates among different subgroups highlight the ongoing need for outreach strategies that target vulnerable populations, experts contend.
Northwestern deploys new mobile stroke unit equipped with 32-slice CT scanner
The MSU operates 365 days a year and covers 138 square miles. Hundreds of patients have been treated through the MSU, with more than 500 receiving critical care in it 2025 alone.
MRI findings suggest parts of the brain reorganize to become 'younger' after a stroke
The finding could signal that the brain has the potential to heal itself in the long-term after a stroke.
Helium prices spike as war rages on—should MRI providers be worried?
The ramifications of the conflict in the Middle East may soon extend beyond the gas pump and into the healthcare sector, experts are cautioning.
Department of energy partners to bolster domestic radioisotope supply
Gadolinium-153, or Gd-153, is routinely used to calibrate nuclear imaging equipment. It has been in short supply since 2023 when global distribution of the radioisotope came to a halt.

Explainable AI model accurately auto-labels chest X-rays from open access datasets

A model that can achieve accuracy in line with that of radiologists when labeling open-access datasets could be a key factor to overcoming limitations of artificial intelligence implementation, researchers explained in Nature Communications.

Despite radiation exposure and fracture risk, pricey QCT bone density scans are rising in popularity

The increase may be an unintended result of a cut in DXA reimbursement rates in 2007, a MedPage Today article suggests.

Experts highlight 'suboptimal' rates of CMS-required shared decision making encounters prior to LDCT

These findings underscore the need for better implementation of shared decision-making (SDM) models, as well as more thorough counseling documentation, as low-dose CT (LDCT) lung screen coverage is dependent on these factors, experts suggested.

Significant disparities exist in utilization of self-scheduling radiology exams, research shows

Researchers revealed that less than 1% of more than 46,000 patients took advantage of online self-scheduling tools.

Memory complaints associated with structural brain abnormalities and increased dementia risk

In participants who reported concern about their subjective memory, higher white matter hyperintensity volumes were observed and those individuals exhibited 174% faster cognitive decline than their peers.

AI boosts performance of novice nurses when assessing pregnant patients via ultrasound

Using a handheld probe and smartphone, nurse midwives were able to estimate gestational age as accurately as certified sonographers.

Experts evaluate new consensus recommendations involving rare cancer on CT

Researchers referred to the newly developed Korean Society of Abdominal Radiology consensus recommendations when evaluating the CT scans of patients with extrahepatic bile duct cancer.
