Purpose To evaluate whether a dual-energy (DE) computed tomographic (CT) virtual noncalcium technique can improve the detection rate of acute thoracolumbar vertebral compression fractures in patients with osteoporosis compared that at magnetic resonance (MR) imaging depending on level experience reading radiologist. Materials and Methods This retrospective study was approved by institutional ethics committee. Informed consent obtained from all patients. Forty-nine who were suspected having...
Objectives The aim of this study was to perform an objective and subjective image analysis traditional advanced noise-optimized virtual monoenergetic imaging (VMI) algorithms standard linearly blended images in third-generation dual-source dual-energy computed tomography angiography (DE-CTA) the thorax abdomen. Materials Methods Thoracoabdominal DE-CTA examinations 55 patients (36 male; mean age, 64.2 ± 12.7 years) were included retrospective institutional review board–approved study....
Objectives The aim of this study was to evaluate the effects on objective and subjective image quality virtual monoenergetic reconstructions at various energy levels dual-energy computed tomography (DECT) in patients with head neck cancer. Materials Methods We included 71 (53 men, 18 women; age, 59.3 ± 12.0 years; range, 33–90 years) biopsy-proven untreated primary (n = 55) or recurrent 16) squamous cell carcinoma who underwent DECT. Images were reconstructed a linear blending setting...
To determine whether machine learning assisted-texture analysis of multi-energy virtual monochromatic image (VMI) datasets from dual-energy CT (DECT) can be used to differentiate metastatic head and neck squamous cell carcinoma (HNSCC) lymph nodes lymphoma, inflammatory, or normal nodes. A retrospective evaluation 412 cervical 5 different patient groups (50 patients in total) having undergone DECT the between 2013 2015 was performed: (1) HNSCC with pathology proven adenopathy, (2) benign...
To evaluate the feasibility of phantomless in vivo dual-energy computed tomography (CT)-based three-dimensional (3D) bone mineral density (BMD) assessment comparison with dual x-ray absorptiometry (DXA).This retrospective study was approved by institutional review board, and requirement to obtain informed consent waived. Data from clinically indicated CT DXA examinations within 2 months, comprising lumbar spine 40 patients, were included. By using automated dedicated postprocessing software,...
Objective The aim of this study was to evaluate the impact a noise-optimized virtual monochromatic imaging algorithm (VMI+) on image quality and diagnostic accuracy at dual-energy computed tomography angiography (CTA) lower extremity runoff. Materials Methods This retrospective Health Insurance Portability Accountability Act–compliant approved by local institutional review board. We evaluated CTA studies runoff in 48 patients (16 women; mean age, 63.3 ± 13.8 years) performed third-generation...
The aim of this study was to investigate the value third-generation dual-source dual-energy computed tomography (DECT) iodine and fat quantification in differentiating adrenal gland adenomas from metastases.Sixty-two patients (38 men 24 women; mean age, 69.1 years) underwent clinically indicated DECT abdomen on a scanner. Examinations were retrospectively included due detected masses. For each lesion, unenhanced contrast-enhanced attenuation values, as well density fraction, recorded....
The aim of this study was to investigate the impact virtual monoenergetic imaging (VMI+) and dual-energy computed tomography perfusion maps (DECT-PMs) on reader confidence diagnostic accuracy in pulmonary angiography (DE-CTPA) studies with suboptimal contrast attenuation, compared standard linearly blended reconstruction series.Dual-energy examinations attenuation 68 patients suspected embolism (PE) were included institutional review board-approved retrospective study. Virtual series at 40...
Purpose To assess the diagnostic performance of dual-energy CT with reconstruction virtual noncalcium (VNCa) images for detection lumbar disk herniation compared standard image reconstruction. Materials and Methods For this retrospective study, 41 patients (243 intervertebral disks; overall mean age, 68 years; 24 women [mean years] 17 men years]) underwent clinically indicated third-generation, dual-source, 3.0-T MRI within 2 weeks between March 2017 January 2018. Six radiologists, blinded...
Abstract Background Bone age (BA) assessment performed by artificial intelligence (AI) is of growing interest due to improved accuracy, precision and time efficiency in daily routine. The aim this study was investigate the accuracy a novel AI software version for automated BA comparison Greulich-Pyle method. Methods Radiographs 514 patients were analysed retrospective study. Total assessed independently three blinded radiologists applying GP method software. Overall gender-specific results,...
To evaluate the predictive value of volumetric bone mineral density (BMD) assessment lumbar spine derived from phantomless dual-energy CT (DECT)-based material decomposition as an indicator for 2-year occurrence risk osteoporosis-associated fractures.L1 92 patients (46 men, 46 women; mean age, 64 years, range, 19-103 years) who had undergone third-generation dual-source DECT between 01/2016 and 12/2018 was retrospectively analyzed. For BMD assessment, dedicated postprocessing software using...
