A comparative study of MR imaging profile of titanium pedicle screws

Abstract

Slight differences in the percentage of titanium among the three pedicle screw systems does not appear to result in artifact differences during MR imaging. Therefore, with regard to imaging profile considerations, the three systems studied should be considered interchangeable.

The interobserver-validated relevance of intervertebral spacer materials in MRI artifacting

“…The MRI imaging behavior of metallic spinal implants is well documented in the literature [6,8,12,18,19]. However, the aims of the published studies differed in that most focused on determining sequence-related artifact size.…”

Big Data Usage in the Marketing Information System

“…The capture in batches is replaced by the streaming capture. Big data, therefore, regards to a massive volume of zettabytes information rather than terabytes, captured from different sources, in several formats, and in real time [11].…”

“…According to an IBM [11] report, the three characteristics that would define big data are volume, speed and variety, as together they would have created the need for new skills and knowledge in order to improve the ability to handle the information (Figure 1).…”

“…Companies that are not prepared to deal with the challenge find support in outsourcing the process [11]. According to Soat (2013) [19], the attribution of scores for information digitally available (e-scores) would be one of the ways of working with information from different origins, including personal data (data collected from fidelity programs or e-mail messages), browsing data collected through cookies, and outsourced data, collected from financing institutes, censuses, credit cards.…”

Application of Extended Multiplicative Signal Correction to Short-Wavelength near Infrared Spectra of Moisture in Marzipan

“…The short-wavelength near infrared (SW-NIR) spectroscopy (700 -1100 nm) is a relatively new analytical technique with a high potential for food analysis [6][7][8][9][10]. The SW-NIR presents several advantages over conventional near-infrared methods (900 -2500 nm): 1) Absorption in this wavelength region arises from the thirdand fourth overtone vibrational (CH, OH, NH) transitions which are characterized by low extinction coefficients; 2) Signal-to-noise ratios on the order of 10,000:l can be obtained, thus making very subtle changes in the spectra useful for analysis; 3) Good quantitative results can be obtained for highly scattering samples [8].…”
