Visualization of the middle meningeal artery on photon-counting detector CT: Comparison with energy-integrating detector CT
The middle meningeal artery (MMA) branches from the external carotid artery, and it is the major dural artery [1]. The MMA is also the target artery for the embolization of intracranial tumors and dural arteriovenous fistulas [2,3]. It has been suggested that embolization of the MMA is useful for the prevention of recurrences of chronic subdural hematomas [4,5]. The MMA is known to merge with intracranial blood vessels via numerous branches, and its running and anastomoses have exhibited varying…

Contemporary trends in utilization of pediatric cardiac imaging in children's hospitals
There has been an increase in availability and utilization of cardiac CT (CCT) and magnetic resonance (CMR) imaging in pediatric cardiology. Understanding trends in their utilization can provide foundational data for defining appropriate use of these tests in pediatrics, and guide resource distribution enhance access to these modalities.

Ultra-high resolution photon-counting detector coronary CT minimizes overestimation bias compared to invasive reference
Photon-counting detector CT with ultra-high-resolution (UHR) mode shows promise in enhancing coronary assessment by offering higher spatial resolution. In the present study, UHR- coronary CT angiography (CCTA) was compared to invasive quantitative coronary angiography (QCA) for evaluating coronary stenosis. Results revealed that UHR-CCTA significantly reduces overestimation bias in stenosis measurements, particularly in heavily calcified plaques, a known limitation of previous imaging methods. T…

The Association between opportunistic DECT-derived bone values and vertebral fracture status
Osteoporosis is a major cause of spinal insufficiency fractures but often remains underdiagnosed. Dual-energy CT (DECT) enables reliable assessment of bone mineral density (BMD), but its limited accessibility highlights the need for alternative metrics. This study investigates the association between vertebral fracture status, DECT-derived BMD and alternative bone quality assessments, including Hounsfield Unit (HU)-based assessment and cortical thickness ratio.

DWI/ADC in response assessment after local-regional treatment of HCC – Pearls and Pitfalls
Hepatocellular carcinoma (HCC) is the most common primary liver cancer which usually develops in the setting of liver cirrhosis. Curative treatment strategies for HCC involve tumor resection, liver transplantation or ablation. However, many patients present with advanced-stage disease or multifocal tumors which make them unsuitable for radical treatment options. In such cases, locoregional therapy (LRT) such as transarterial chemoembolization (TACE), transarterial radioembolization (TARE) can be…

Opinions and preferences regarding artificial intelligence use in healthcare delivery: results from a national multi-site survey of breast imaging patients
Artificial intelligence (AI) utilization is growing, but patient perceptions of AI are unclear. Our objective was to understand patient perceptions of AI through a multi-site survey of breast imaging patients.
