A new technique using contrast enhanced micro-computed tomography (micro-CT) was developed to improve the ability to detect dentinal cracks in teeth and assess associated risks to oral health. Extracted, whole human molars that exhibited visual evidence of external cracks following extraction and machined, partially fractured elephant dentin specimens were labeled by BaSO(4) precipitation and i...

Background: F-FDG PET/CT imaging is widely utilized in the clinical evaluation of patients with suspected or documented lymphoma. The aim was to describe our cumulative experience with a multimodal F-FDG-directed lymph node surgical excisional biopsy approach in patients with suspected lymphoma. Methods: Thirteen patients (mean age 51 (±16;22–76) years), with suspected new or suspected recurren...

Abstract In this manuscript, we present a preliminary report on the use of virtual palaeontology methodologies in two natural history museums central Italy, Geology and Paleontology Museum Florence Civic Natural Sciences Faenza. Despite differences between (in terms history, type size collections, etc.), surface computed tomography (CT) scans has allowed acquisition consistent amount data to cr...

STUDY OBJECTIVES We evaluated the feasibility, safety, and efficacy of CT-guided transbronchial biopsy (TBB) using an ultrathin bronchoscope with navigation by virtual bronchoscopy (VB) for small peripheral pulmonary lesions of < 20 mm in diameter. DESIGN A pilot study. SETTING A national university hospital. PATIENTS We performed CT-guided TBB after VB navigation for 25 patients with 26 ...

A defined agar medium (hereinafter designated caprylate-thallous [CT5 agar) containing 0.01% yeast extract, 0.1% caprylic (n-octanoic) acid, and 0.025% thallous sulfate is highly selective for all Serratia species and effectively discriminates against most non-Serratia strains likely to be in the same habitats. The selectivity of CT agar is demonstrated by the very high efficiency of colony for...

Chlamydia trachomatis (CT) is the leading sexually transmitted bacterial infection. The continued global burden of CT infection strongly predicates the need for a vaccine to supplement current chlamydial control programs. The correlates of protection against CT are currently unknown, but they must be carefully defined to guide vaccine design. The localized nature of chlamydial infection in colu...

The direct observation of the interfacial debonding between carbon fibers and an epoxy matrix was achieved through in-situ tensile fatigue testing on beamline a synchrotron radiation facility, SPring-8. Preliminary tests were conducted using miniature specimens with multiple embedded under high magnification digital microscope. static loading-unloading revealed clear nominal stress 50 MPa indic...

Porosity of polypropylene samples was investigated by applying X-ray micro-computed tomography (micro-CT), which is getting more and popular as a non-destructive method. Microspheres were applied blowing agent at three concentrations: 3%, 6% 9% weight. Tensile testing specimens obtained injection molding technology its central, measuring part examined micro – CT. Results compared to porosity ca...

INTRODUCTION CT scan-guided fine-needle aspiration (FNA) of lung nodules is a well-established diagnostic technique. In our institution, both FNA and tissue core biopsy (using a 20-gauge needle) under CT scan guidance are routinely performed during the same procedure, and a preliminary diagnosis (an immediate assessment) is rendered. We compared core roll preparations (CRPs) with aspirate smear...

We herein report a case of invasive candidiasis presenting rare findings on chest computed tomography (CT). The chest CT scan showed multiple small cavitary lesions and nodules with surrounding ground-glass opacity, and also bilateral pleural effusion. Although this CT finding is thought as specific for pulmonary aspergillosis, two sets of blood culture specimens were drawn which yielded Candid...
