OBJECTIVES The goal of our study was to evaluate the efficacy and safety of a new type of automated cutting needle for tissue-core lung biopsy under real-time CT fluoroscopic guidance. DESIGN Observational MATERIALS AND METHODS One hundred ten percutaneous needle tissue-core lung biopsies were performed with the Auto Surecut needle (Create Medic; Yokohama, Japan) under CT fluoroscopic guida...

The Poisson ratio (PR) is a fundamental mechanical parameter that approximates the ratio of relative change in cross sectional area to tensile elongation. However, the PR of extraocular muscle (EOM) is almost never measured because of experimental constraints. The problem was overcome by determining changes in EOM dimensions using computed X-ray tomography (CT) at microscopic resolution during ...

Abstract Sample pooling strategy was intended to determine the optimal parameters for group testing of pooled specimens detection SARS-CoV-2 and process them without significant loss test usability. Standard molecular diagnostic laboratory equipment, commercially available centrifugal filters, RNA isolation kits SARS Cov2 PCR tests were used. The basic idea combine concentrate several samples m...

BACKGROUND AND PURPOSE The growth of cross-sectional imaging has increased the detection of nonpalpable head and neck masses. We sought to determine the reliability of CT-guided fine-needle aspiration (FNA) over 216 consecutive cases. METHODS We retrospectively reviewed histopathologic findings and notes from 216 consecutive head and neck CT-guided FNA procedures performed between 1993 and 20...

BACKGROUND A hook wire has been most widely used for computed tomography (CT)-guided localization before video-assisted thoracoscopic surgery (VATS). However, microcoils have been suggested to replace wires. The purpose of this study was to compare the efficacy, VATS procedure time, and excised volume of specimens of CT-guided localization using a hook wire and microcoil. METHODS The medical ...

We performed percutaneous CT-guided needle biopsies with a transfacial approach in the diagnosis of lesions of the parapharyngeal region. Via the buccal space, core needle biopsy specimens were obtained in eight patients with known parapharyngeal abnormalities identified by CT and/or MR imaging. In all cases, sufficient tissue was obtained to provide a definitive histologic diagnosis. There wer...

We determined the prevalence of Shiga toxin-producing Escherichia coli (STEC) in diarrheal stool samples from Nebraska by three methods: cefixime-tellurite sorbitol MacConkey (CT- SMAC) culture, enterohemorrhagic E. coli (EHEC) enzyme immunoassay, and stx1,2 polymerase chain reaction (PCR). Fourteen (4.2%) of 335 specimens were positive by at least one method (CT-SMAC culture [6 of 14], EHEC en...

A case of histiocytic medullary reticulosis with splenic infaraction from a 23-year-old male is presented. Radiologic findings on selective spleen scintigraphy and abdominal CT are described. Selective spleen scintigraphy showed huge, multilobulated spleen with numerous photon-deficient areas in it and peripherally. Abdominal CT showed large peripheral band-like low density and infiltrative les...

We report a case of methanol intoxication in which the initial CT scans appeared normal. MR at 4 days showed the typical putaminal lesions of methanol intoxication and, in addition, peripheral white matter lesions that spared a thin rim of subcortical white matter. A CT scan at 17 days showed the putaminal and white matter lesions. The white matter lesions correspond well to lesions previously ...
