The purpose of this study was to measure the number of repeat computed tomography (CT) scans performed across an established health information exchange (HIE) in New York City. The long-term objective is to build an HIE-based duplicate CT alerting system to reduce potentially avoidable duplicate CTs.

The multiscale pore structure of mesoporous silica microspheres plays an important role for tuning mass transfer kinetics in technological applications such as liquid chromatography. While local analysis of a pore network in such materials has been previously achieved, multiscale quantification of microspheres down to the nanometer scale pore level is still lacking.

YNU-5 (YFI type) is the first zeolite reported with interconnected 12-, 12-, and 8-ring pores showing a remarkable catalytic potential towards the dimethyl ether (DME)-to-olefin reaction. In this work, the structures of the as-synthesized, calcined and dealuminated YNU-5 zeolites, were investigated by various techniques with special emphasis on advanced electron microscopy methods.

Interstitial lung disease (ILD) is a severe systemic manifestation of rheumatoid arthritis (RA). Highresolution computed tomography (HRCT) represents the gold standard for the diagnosis of ILD, but its routine use for screening programs is not advisable because of both high cost and X-ray exposure.

Cryo-electron tomography (cryo-ET) enables 3D imaging of macromolecular structures. Reconstructed cryo-ET images have a “missing wedge” of data loss due to limitations in rotation of the mounting stage.

Cryo-electron tomography is an important tool to study structures of macromolecular complexes in close to native states. A whole cell cryo electron tomogram contains structural information of all its macromolecular complexes. However, extracting this information remains challenging, and relies on sophisticated image processing, in particular for template-free particle extraction, classification and averaging.

The primary purpose of this guideline is to improve diag- nostic accuracy for adult rhinosinusitis, reduce inappropri- ate antibiotic use, reduce inappropriate use of radiographic imaging, and promote appropriate use of ancillary tests that include nasal endoscopy, computed tomography, and testing for allergy and immune function. Secondary goals include creating a guideline suitable for deriving a performance measure on rhinosinusitis and training participants in guide- line methodology to facilitate future development efforts.

Since its introduction in the early 1970s, computed tomography (CT) has become a robust modality to evaluate extracranial, thoracic, and abdominal vascular distributions. It has become a gold standard to non-invasively image the aorta, pulmonary arteries, great vessels, renal and peripheral arteries. However, cardiac anatomy evaluation with this modality was not possible, due to rapid cardiac motion and slow image acquisition times.

Different terms are employed in the literature to specify this method on investigations: dualbeam coherent interferometry or laser Doppler interferometry, optical coherence tomography (OCT) or optical coherence reflectometry. OCT is analogous to ultrasonic imaging, which measures the intensity of reflected infrared light rather than reflected sound waves from the sample. Time gating is employed so that the time for the light to be reflected back (or echo delay time) is used to assess the intensity of back-reflection as a function of depth.
