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.

Radiologists can reclaim an hour every day with AI assistance

The AI software assisted in various tasks, such as segmenting, labeling and measuring normal structures, providing an automated analysis of pulmonary, cardiac and musculoskeletal findings.

Ultrasound-embeddable AI sharp at diagnosing clogged carotid arteries

Testing AI’s ability to detect carotid artery disease on ultrasound, U.K. researchers have found their algorithm achieved 90% accuracy, along with 87% sensitivity and 82% specificity, at the task.

How COVID-19 made some radiologists newly nimble with workload management

During one surge, the hospital’s CT volumes spiked to 55% higher than pre-pandemic levels—no doubt due to heavy demand for advanced chest imaging.

Pandemic’s hardest hit breast-care segment: Screening mammography

COVID-19 set back screening mammography further than any other category of breast care, dropping schedule adherence during infection peaks to 36% of pre-pandemic rates.

Example of various breast MRI protocol sequences that offer different types of soft tissue enhancement. Imaging performed on a Siemens Magnetom system. Breast MRI can help see through dense breast tissue to better detect cancers. #densebreasts #Breastdensity #BreastMRI

Contrast enhanced breast MRI superior to CEM, but accessibility remains an obstacle

In addition to CE-MRI's increased sensitivity for identifying breast cancers, the researchers also found the modality had superior negative likelihood ratios with higher pre-test probabilities for safely ruling out malignancy.

NIH grants $3.5 million toward researching COVID's neurological impact

The funds will be allocated specifically toward neuroimaging and cognitive and immunological tests to explore if and how mild and asymptomatic SARS-CoV-2 infections have a long-lasting impact on neurocognitive function.

Downgrading lung nodules at 3-month follow-up 'may be problematic'

A new analysis suggests that follow-up imaging protocols for certain lung nodules identified via CT may need to be revisited. 

Predicting healthcare utilization in COPD patients using CT and machine learning

Combining CT lung measurements with machine learning models to predict prognosis in COPD patients could help to lessen their reliance on emergency services.
