Multidetector computed tomography enteroclysis (MDCT-E) with neutral enteral and IV contrast enhancement in tumor detection.
No full textAbstract The aim of our study was
to evaluate the reliability of MDCT enteroclysis
(MDCT-E), an emerging
technique of small bowel examination
that combines the advantages of
MDCT examination of the abdomen
and the enteral volume challenge of
enteroclysis, in evaluation of small
bowel neoplasms. In our institutions,
MDCT-E was used to study 456
patients (age range 21–84 years, mean
53 years) admitted for suspicion of
small bowel disease. All examinations
were done on multichannel CT units,
129 on a 16-slice scanner and 327 on
a four-slice scanner. Post-processing
and multiplanar reformatting and interpretation
were performed on dedicated
workstations. After adequate
gastrointestinal preparation and nasoenteric
intubation, small bowel was
distended by methylcellulose infused
by a peristaltic pump. One volumetric
MDCT acquisition was obtained after
120–130 ml of intravenous contrast
medium. Multiplanar reformatting
was based on the image reconstruction
parameters from 3 to 4 mm.
Forty-five small bowel neoplasms
were found; in the remaining cases,
223 Crohn’s diseases and 149 other
abnormalities were detected. All
findings were confirmed by surgery,
endoscopy or clinical follow-up. In
our experience, MDCT-E with neutral
enteral and IV contrast seems to be a
reliable method in the diagnosis of
small bowel neoplasms

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
