CMS has adopted a new CT quality measure seeking to discourage excessive radiation dose while preserving image quality. The score is expressed as the percentage of qualifying studies that exceed predetermined thresholds indicating inadequate (based on noise) or dose. been incorporated into major quality-based payment programs, impacting hospitals and clinician payments; reporting began in January 2025. Following development, practitioners identified spectrum concerns impediments, prompting...
Background Diagnostic reference levels (DRLs) and achievable doses (ADs) were developed for the 10 most commonly performed pediatric CT examinations in United States using American College of Radiology Dose Index Registry. Purpose To develop robust, current, national DRLs ADs as a function patient age size. Materials Methods Data on (ie, patients aged 18 years younger) between 2016 2020 at 1625 facilities analyzed. For head neck examinations, dose indexes analyzed based age; body effective...

PurposeThe deformable nature of the liver can make focal treatment challenging and is not adequately addressed with simple rigid registration techniques. More advanced techniques take deformations into account (eg, biomechanical modeling) but require segmentations whole for each scan, which a time-intensive process. We hypothesize that fully convolutional networks be used to rapidly accurately autosegment liver, removing temporal bottleneck modeling.Methods MaterialsManual on computed...

Existing surveys of radiopharmaceutical doses for U.S. nuclear medicine laboratories are limited scope and size. Dose data important because they can be used to benchmark individual laboratories, understand geographic variations in practice, provide source societal guidelines appropriateness criteria. Diagnostic reference levels (DRLs) achievable administered activities (AAAs) 13 noncardiac adult gamma camera PET/CT examinations were derived retrospectively from American College Radiology...
The American Association of Physicists in Medicine (AAPM) and the Society Nuclear Molecular Imaging (SNMMI) recognized need for a review current state nuclear medicine physics training to explore pathways improving opportunities. For these reasons, two organizations formed joint AAPM/SNMMI Ad Hoc Task Force on Physics Training. mission this task force was assemble representative group stakeholders to:• Estimate demand board-certified physicists next 5-10 years,• Identify critical issues...

To examine dose-response associations between use of specific social media sites and the electronic cigarettes (e-cigarettes) traditional cigarettes.This was a cross-sectional study 298 first-year college students enrolled in fall 2019 semester at large state university. Heckman selection Probit model were used to estimate e-cigarette/traditional cigarette use.Each additional hour per day spent on Snapchat associated with 4.61% increase probability lifetime e-cigarette use. In addition,...
Purpose Grid artifacts occur in digital mammography when synchronization between the grid assembly and generator is not achieved, including malfunctions or subsystems. Such are explicitly monitored evaluated by existing quality control programs. In this study, we developed an automated method for quantifying presence of two‐dimensional (2D) images assessed its utility as a supplement to Methods Four systems (Hologic Dimensions 3D 5000) were configured automatically transfer 2D server where...
Purpose: To perform a dose calibrator (DC) cross‐calibration for assaying SIR‐Spheres patient doses after out‐sourcing dispensing to an outside radiopharmacy. Methods: The setting our DC (CRC‐15R, Capintec) required assay match that of the radiopharmacy (accounting decay) was determined independently 20 dispensed (v‐vial in acrylic shield). mean twenty settings, plus and minus one two standard deviations, as well as, minimum maximum, were computed. For next doses, activity measured using...
