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.

AI-based mammo screening protocol reduces radiologist workload by 62%

Researchers reported that the artificial intelligence system was able to interpret more than 114,000 screening mammograms using a reading protocol with high sensitivity and specificity.

Leslee Shaw, PhD, and former presidents of both SCCT and ASNC discusses the role of CT and FFR-CT in the 2021 chest pain guidelines.

VIDEO: Cardiac CT now recommended as a front-line chest pain assessment tool

Leslee Shaw, PhD, director of the Blavatnik Family Women’s Health Research Institute at Mount Sinai Hospital in New York and former president of the Society of Cardiovascular Computed Tomography (SCCT) and the American Society of Nuclear Cardiology (ASNC), explains the role of cardiac computed tomography (CT) in the recent 2021 chest pain guidelines.

CMS coverage decision for Alzheimer's drug, related PET scans sparks concern in imaging community

In a statement released on April 14, MITA cautioned that the coverage decision will “severely limit patient access” to amyloid PET diagnostics and anti-amyloid monoclonal antibodies treatment.

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.
