Tooth-in-eye standardized longitudinal radiological CT monitoring: Clinical impact in a fourteen-year series
Report the natural history of laminar resorption quantitatively and qualitatively on serial CT after sight-restoring osteo-odonto-keratoprosthesis (OOKP) surgery, conduct OOKP survival analysis, and describe how standardized CT monitoring using a three-prong approach aids clinical evaluation and management, including decision-making for prophylactic OOKP exchange.

The value of a deep learning image reconstruction algorithm for assessing vertebral compression fractures using dual-energy computed tomography
With a rising incidence, thoracolumbar vertebral compression fractures (VCFs) have emerged as a pressing public health concern due to risk of severe disability, especially in industrialized countries with increasing aging populations[1]. Differentiating between acute and chronic fractures is crucial for determining the appropriate treatment approach (whether conservative or surgical) and reducing the risk of associated complications.

Cost-effectiveness of photon counting detector CT for coronary artery disease diagnostics: A Finnish healthcare perspective
The purpose of this study was to evaluate the cost-effectiveness of photon-counting detector computed tomography (PCD-CT) compared to energy-integrating detector CT (EID-CT) for coronary artery disease (CAD) diagnostics in the Finnish healthcare context.

Impact of cardiac phase selection on computational fluid dynamics analysis
The selection of cardiac phase in coronary computed tomography angiography (CCTA) may affect computational fluid dynamics (CFD)-derived hemodynamic metrics; however, this influence is not well-quantified, particularly in anomalous coronary anatomies. This study aims to evaluate how cardiac phase selection impacts CFD outcomes in normal and anomalous coronary arteries.

Roadmap analysis for coronary artery stenosis detection and percutaneous coronary intervention prediction in cardiac CT for transcatheter aortic valve replacement
The new artificial intelligence-based software, Roadmap (HeartFlow), may assist in evaluating coronary artery stenosis during cardiac computed tomography (CT) for transcatheter aortic valve replacement (TAVR).

Balanced steady-state free precession MRI: History and evolution
Magnetic Resonance Imaging (MRI) was developed on the principle of Nuclear Magnetic Resonance (NMR), first observed in 1938 by Rabi [1] and subsequently formulated in 1946 by Bloch [2] and Purcell [3]. During the next two decades, NMR remained primarily a spectroscopy tool due to limited imaging technology, computing power, and clinical awareness. Its medical potential was not realized until 1971, when Damadian first noted that NMR relaxation times differed in cancerous and normal tissue [4]. La…

Cardiac computed tomography for prosthetic heart valve assessment. An expert consensus document of the Society of Cardiovascular Computed Tomography (SCCT), the American College of Cardiology (ACC), the European Society of Cardiovascular Radiology (ESCR), the North American Society of Cardiovascular Imaging (NASCI), the Radiological Society of North America (RSNA), the Society for Cardiovascular Angiography & Interventions (SCAI) and Society of Thoracic Surgeons (STS)
Prosthetic heart valve (PHV) dysfunction is increasingly seen due to the increase in the number of PHV that are being implanted worldwide. Cardiac CT imaging has emerged as a valuable tool to assess PHVs and determine the cause of dysfunction. This consensus document first summarizes the available techniques for PHV assessment. Then the use of CT in PHV (dys)function assessment is discussed in detail including consensus statements for correct indications and patient selection for CT assessment o…

Human factors in diagnostic radiology: practical challenges and cognitive biases
The science of human factors refers to the individual and environmental influences which impact personal behaviour and subsequently health and safety within the workplace [1,2]. A triad of interdependent factors within the healthcare system (Fig. 1) can align to produce medical error via the well-documented ‘Swiss cheese’ model, with 1 in 20 hospital admissions believed to include a medical error of some shape or form [3]. Persistent effort is necessary to raise awareness of human factors and ut…
