Digital representations of physical specimens and objects have dramatically expanded the impact of natural history collections, making them more accessible and transforming research. These representations, even when they are only descriptive text (e.g., metadata), have made research possible at large sca...
STUDY DESIGN: Feasibility study; 10patients with piriformis muscle syndrome were injected with botulinum toxin Ausing a US-guided procedure. Then patients were administered 2 mL iodinatedcontrast and were then transferred to the CT scanner, where they underwentpelvic and hip imaging to assess intramusc...
Coronary Plaque Component Analysis.—The use of an advanced workstation analysis application allows the generation of spectral attenuation curves by plotting the attenuation values (in Hounsfield units) of a material for every monochromatic energy from 40 to 140 keV (1-keV interval; x-axis, monochro...

(stage II: HR=25.7, 95% CI 6.8-96.7; stage III: HR=18.1, 95% CI 7.3-45.1). Within the MRD+ group, pts receiving ACT had longer DFS compared to those in the observation group (median DFS: 18.7 vs 6.7 months; HR=3.9, 95% CI: 1.3-11.5, p=0.01). In contrast, no benefit of ...
Here propose a computer-aided diagnosis (CAD) system to differentiate COVID-19 (the coronavirus disease of 2019) patients from normal cases, as well as to perform infection region segmentation along with infection severity estimation using computed tomog

Two scans of the same patient showing that PANDA can detect dilated pancreatic duct (usually caused by PDAC) even when the PDAC is not scanned. f, PANDA can detect early-stage PDACs and metastatic cancer that was initially misdetected by the radiologists on chest non-contrast CT (COVID-19...
Conventional CT scanners use a detector technology which has the crucial disadvantage that the detected X-ray photons are integrated, and thus unable to extract the spectral information of the polychromatic X-ray spectrum passing through the imaged object. In contrast, current clinical Spectral CT sca...
our own routine, aspects of sustainability when dealing with CM in computed tomography are discussed in this review using the example of a hospital and a private practice.ConclusionWhen planning and performing contrast-enhanced CT examinations, personalized CM protocols can make CM use more efficient....
