To assess the accuracy of dual-energy CT (DECT) for diagnosing gout, and to explore whether it can have any impact on clinical decision making beyond established diagnostic approach using polarising microscopy synovial fluid (diagnostic yield).Diagnostic single-centre study 40 patients with active 41 individuals other types joint disease. Sensitivity specificity DECT gout was calculated against a combined reference standard (polarising electron fluid). yield scanning, third cohort assembled...
To estimate the accuracy, sensitivity, specificity, and interobserver agreement of dual-energy computed tomography (CT) in detection uric acid crystals joints or periarticular structures patients with arthralgia suspected having gout, joint aspiration results as reference standard.With institutional review board approval, patient consent, HIPAA compliance, 94 (age range, 29-89 years) underwent dual-source, (80 140 kVp) CT a painful joint. A material decomposition algorithm was used to...
Photon-counting detector (PCD) CT is an emerging technology that has led to continued innovation and progress in diagnostic imaging after it was approved by the U.S. Food Drug Administration for clinical use September 2021. Conventional energy-integrating (EID) measures total energy of x-rays converting photons visible light subsequently using photodiodes convert digital signals. In comparison, PCD directly records x-ray as electric signals, without intermediate conversion light. The...
The aim of this study was to investigate the impact on metal artifacts and dose efficiency using a tin filter in combination with high-energy threshold (TH) images photon-counting detector (PCD) computed tomography (CT) system.A 3D-printed spine pedicle screws scanned PCD-CT system without filtration. Image noise severity were measured for low-energy (TL) TH images. In prospective, institutional review board-approved, Health Insurance Portability Accountability Act-compliant study, 20...
Background Photon-counting detector (PCD) CT and deep learning noise reduction may improve spatial resolution at lower radiation doses compared with energy-integrating (EID) CT. Purpose To demonstrate the diagnostic impact of improved in whole-body low-dose scans for viewing multiple myeloma by using PCD denoising conventional EID Materials Methods Between April July 2021, adult participants who underwent a scan were prospectively enrolled scanned system ultra-high-resolution mode matched...
The purpose of this article is to describe the imaging characteristics pseudoangiomatous stromal hyperplasia, where primary histologic component was hyperplasia.The tumoral form hyperplasia rare. most common mammographic and sonographic finding a circumscribed mass. Its appearance on MRI nonspecific, but it may present as clumped nonmasslike persistent enhancement contrast-enhanced imaging. Biopsy guided by be necessary confirm diagnosis.
The purpose of our study was to describe the imaging findings in adenoid cystic carcinoma (ACC) breast, with pathologic and clinical correlation.We retrospectively searched surgical database from January 1994 through December 2008 for cases pathologically proven ACC breast. Of approximately 15,000 breast biopsies, 11,250 were malignant. Eleven (0.1% all malignancies), available review, included study.Mammographically (n = 10), tumors appeared as developing asymmetric densities or irregular...
Objective.To develop a convolutional neural network (CNN) noise reduction technique for ultra-high-resolution photon-counting detector computed tomography (UHR-PCD-CT) that can be efficiently implemented using only clinically available reconstructed images. The developed was demonstrated skeletal survey, lung screening, and head angiography (CTA).Approach. There were 39 participants enrolled in this study, each received UHR-PCD an energy integrating (EID) CT scan. CNN uses image-based...
