Background The first clinical CT system to use photon-counting detector (PCD) technology has become available for patient care. Purpose To assess the technical performance of PCD with phantoms and representative participant examinations. Materials Methods Institutional review board approval written informed consent from four participants were obtained. Technical a dual-source was measured standard high-spatial-resolution (HR) collimations. Noise power spectrum, modulation transfer function,...

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...

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...

Purpose To evaluate if cardiac magnetic resonance elastography (MRE) can measure increased stiffness in patients with amyloidosis. Myocardial tissue plays an important role function. A noninvasive quantitative imaging technique capable of measuring myocardial could aid disease diagnosis, therapy monitoring, and prognostic strategies. We recently developed a high‐frequency MRE making measurements. Materials Methods In all, 16 volunteers 22 amyloidosis were enrolled this study after...

<h3>BACKGROUND AND PURPOSE:</h3> CSF-venous fistulas are a common cause of spontaneous intracranial hypotension. Lateral decubitus digital subtraction myelography and CT the diagnostic imaging standards to identify these fistulas. Photon-counting has technological advantages that might improve fistula detection, though no large studies have yet assessed its performance. We sought determine yield photon-counting detector for detection in patients with <h3>MATERIALS METHODS:</h3>...

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...

Photon counting detector (PCD) computed tomography (CT) is a paradigm-shifting innovation in CT imaging which was recently granted approval for clinical use by the US Food and Drug Administration. PCD-CT allows generation of multi-energy images with increased contrast scanning speed or ultra-high spatial resolution (UHR) lower radiation doses, compared to currently used energy integrating (EID) CT. Since recognition bone disease related multiple myeloma important diagnosis management...

BACKGROUND. Spectral localizer images from photon-counting detector (PCD) CT can be used for bone mineral density (BMD) evaluation given their 2D projectional nature and material decomposition capability. As all examinations include images, this approach could allow opportunistic osteoporosis screening of patients undergoing clinically indicated imaging with PCD CT. OBJECTIVE. The purpose study was to assess the use spectral derivation areal BMD (aBMD) values T-scores, dual-energy x-ray...

OBJECTIVE The purpose of this study was to determine the effect osteoporosis medications on opportunistic CT-based Hounsfield units (HU). METHODS Spine and nonspine surgery patients were retrospectively identified who had been treated with romosozumab for 3 12 months, teriparatide &gt; denosumab or alendronate months. HU measured in L1–4 vertebral bodies. One-way ANOVA used compare mean change among five treatment regimens. RESULTS In total, 318 (70% women) included, a age 69 years BMI 27...
