The purpose of this study was to evaluate the consequences of different choices of acquisition parameters on the actual image noise and on the patient dose with an automatic tube current modulation system. The CT investigated was a GE Lightspeed 16-slice and an anthropomorphic phantom was used to simulate the patient. Several acquisitions were made varying(More)
INTRODUCTION X-ray computed micro-tomography scanning allows high-resolution 3-dimensional imaging of small objects. In this study, micro-CT scanning was used to compare the ability of manual and mechanical glide path to maintain the original root canal anatomy. METHODS Eight extracted upper first permanent molars were scanned at the TOMOLAB station at(More)
A 58-year-old previously healthy man presented with diplopia of rapid onset over a few days. Examination demonstrated bilateral sixth and right fourth cranial nerve palsy. MR imaging showed a large sellar mass with significant destruction of the pituitary fossa. Laboratory tests revealed very high serum prolactin (2,483 ng/dl, reference range 3–13 ng/dl).(More)
This study was done to assess breast density on digital mammography and digital breast tomosynthesis according to the visual Breast Imaging Reporting and Data System (BI–RADS) classification, to compare visual assessment with Quantra software for automated density measurement, and to establish the role of the software in clinical practice. We analysed 200(More)
INTRODUCTION The aim of this micro-computed tomography study was to describe the shaping properties of ProGlider/ProTaper Next (PG/PTN) and ScoutRace/BioRace (SR/BR) nickel-titanium rotary systems. METHODS Thirty maxillary first permanent molars were selected. Mesiobuccal canals were randomly assigned (n = 15) to PG/PTN or SR/BR groups. Irrigation was(More)
AIM To evaluate the ability of ProGlider instruments, PathFiles and K-files to maintain canal anatomy during glide path preparation using X-ray computed micro-tomography (micro-CT). METHODOLOGY Forty-five extracted maxillary first permanent molars were selected. Mesio-buccal canals were randomly assigned (n = 15) to manual K-file, PathFile or ProGlider(More)
To retrospectively assess the risk of breast cancer associated with the radial scar (RS) microhistological diagnosis, also taking into consideration the percutaneous biopsy devices used, as well as the different performances of the mammographic systems (analogical, digital and tomosynthesis) in the radiological diagnosis of RS. Between March 2002 and(More)
OBJECTIVES To create and to spread a new interactive multimedia instrument, based upon virtual reality technologies, that allows both the running simulation of machines and equipment and the reproduction via Web of complex three-dimensional (3D) anatomical models such as the skull. METHODS There were two main aspects of the project, one of design(More)
