Image quality and radiation dose of cone-beam CT versus multidetector CT for upper extremity osteosynthesis
Abstract This study compared image quality and radiation dose between cone-beam computed tomography (CBCT) and multidetector computed tomography (MDCT) under equivalent scanning settings, focusing on postoperative imaging after upper extremity osteosynthesis. A distal radius plate was implanted in a cadaveric forearm to simulate postoperative conditions. A total of twenty-four scans were performed using both modalities.
Deep Learning Denoising Algorithm for Improved Assessment of Coronary Arteries in Transcatheter Aortic Valve Implantation CT Imaging
Abbreviations AU (agatston units) BMI (body mass index) CAD (coronary artery disease) DLD (deep learning denoising) HU (attenuation values) ICA (invasive coronary angiography) NPV (negative predictive value) PPV (positive predictive value) ROI (region of interest) SD (standard deviations) TAVI (transcatheter aortic valve implantation) Key Words Computed tomography angiography Deep learning Coronary artery disease Noise INTRODUCTION Coronary artery disease (CAD) burdens about 50% of patients...

Value of Dual-Energy CT-Derived Metrics for the Prediction of Bone Non-union in Distal Radius Fractures
Bone non-union is a serious complication of distal radius fractures (DRF) that can result in functional limitations and persistent pain. However, no accepted method has been established to identify patients at risk of developing bone non-union yet. This study aimed to compare various CT-derived metrics for bone mineral density (BMD) assessment to identify predictive values for the development of bone non-union.

Indicators for Hospitalization in Acute Pulmonary Embolism: Uncover the Association Between D-dimer Levels, Thrombus Volume and Radiomics
The advent of advanced computed tomography (CT) technology and the field of radiomics has opened up new avenues in diagnostic assessments. Increasingly, there is substantial evidence advocating for the incorporation of quantitative imaging biomarkers in the clinical decision-making process.

Association of Phantomless Dual-Energy CT-based Volumetric Bone Mineral Density with the Prevalence of Acute Insufficiency Fractures of the Spine
To evaluate the bone mineral density (BMD) of the lumbar spine derived from dual-energy CT (DECT)-based volumetric material decomposition and its association with acute insufficiency fractures of the thoracolumbar spine. L1 of 160 patients (77 men, 83 women; mean age 64.3 years, range, 22-94 years) who underwent third-generation dual-source DECT between January 2016 and December 2021 due to suspected insufficiency fractures was retrospectively analyzed.
Free‐breathing accelerated whole‐body MRI using an automated workflow: Comparison with conventional breath‐hold sequences
2.4 Qualitative and quantitative image evaluation Image evaluation was performed in a blinded fashion on a commercially available picture archiving and communication system (Centricity, Version 4.2; GE Healthcare, Chicago, USA), as previously described.18 All MR series were independently analyzed by two radiologists (T.J.V. and K.E., board-certified radiologists with 34 and 17 years of experience in MRI, respectively) regarding image characteristics and the demarcation of pathologies with a...
