    PURPOSE: This study aims to evaluate the analysis and publication rates of abstracts presented at the Turkish National Radiology meetings in 2010–2012. METHODS: Abstracts presented in the national radiology meetings of 2010, 2011, and 2012 were included in the study. The presentations were classified according to presentation type (oral or poster presentations), study type, study design, imaged organ or body systems, imaging modalities, time interval between the presentation and the publication date, and the journal in which the article was published. The conversion rate of presentations into full-text articles in peer-reviewed journals were surveyed through PubMed. The time from presentation in the meetings to publication was determined. The distribution of journals was also demonstrated. RESULTS: The total number of presentations submitted in three national radiology meetings was 3,192. The publication rate was 11% for the 2010 meeting, 8.2% for the 2011 meeting, and 9.6% for the 2012 meeting. A total of 300 papers were published, with an average of 15 months (range, 0–42 months) between presentation and final publication. The first three refereed international journals with the most number of papers derived from these meetings were Diagnostic and Interventional Radiology, Clinical Imaging, and European Journal of Radiology. CONCLUSION: The overall publication rate of scientific abstracts from Turkey was lower than those from overseas countries. Encouraging the authors to conduct higher-quality research would raise the publication rate as well as improve the quality and success of our scientific meetings. © Turkish Society of Radiology 2015

    The sensitivity of MR colonography using dark lumen technique for detection of colonic lesions
    (Turkish Society of Gastroenterology, 2014) Beker Acay, Mehtap; Bayramoğlu, Sibel; Acay, Akif
    Background/Aims: To assess the detectability of the lesions with magnetic resonance (MR) colonography using dark lumen technique that had been detected on conventional colonoscopy. Materials and Methods: A total of 38 patients who were suspected to have a colorectal mass between April 2008 and June 2010 were included in this prospective study. Warm tap water was administered via a rectal tube to the patients in prone position. Then, axial T2 true- fast imaging with steady-state precession (FISP), axial T2 half-Fourier acquisition single-shot turbo spin-echo (HASTE), diffusion-weighted images, and T1 vibe fat suppression coronal sequences were obtained. T1 vibe fat suppression sequences on axial coronal planes were repeated after gadolinium contrast medium intravenous injection. MR images were analyzed by two radiologists concurrently. Assessments were done by comparing with conventional colonoscopy and histopathologic findings. Results: Thirteen out of 20 lesions that had been detected on conventional colonoscopy were correctly obtained by MR colonography. None of the three lesions 5 mm or below was seen on MR colonography. Two out of 4 lesions measuring 6-9 mm were seen on MR colonography (50%). Eleven out of 13 lesions 10 mm and above were correctly detected on MR colonography (84.6%). Sensitivity was estimated as 65% when all lesions were evaluated together. Conclusion: MR colonography has a high sensitivity in the diagnosis of colonic pathologies without ionizing radiation. Future investigation will likely lead to wider acceptance of this method to detect colonic pathologies, including perhaps their use in colon cancer screening programs. © 2014 by The Turkish Society of Gastroenterology.
