PACS utilization in radiologic research.

RATIONALE AND OBJECTIVES: The authors investigated patterns of utilization of the digital picture archiving and communication system (PACS) in radiologic publications in order to ascertain whether there may be a correlation between PACS use and demographic/cultural factors such as geographic location, radiologic specialization, and use of advanced radiologic technologies. MATERIALS AND METHODS: A total of 1,037 articles in 22 randomly selected issues of AJR: American Journal of Roentgenology and of Radiology (1999-2001) were reviewed for the rate of PACS use and the type of PACS used. Articles for which PACS use or nonuse was established were further classified according to originating continent or region, imaging modality, study design (whether retrospective or prospective), and the use of advanced radiologic technology. The use of a PACS was then correlated with these factors. The data were recorded and statistics were prepared by means of statistical software. The nonparametric (chi2) test also was run by using this software. RESULTS: PACS had been used and reported in the preparation of 225 of the 1,037 articles. The type of PACS used was mini PACS (eg, systems using digital imaging and communications in medicine [DICOM] protocols or precursors) in 55 (24%) and department- or hospital-wide PACS in 161 (72%). Most of the articles for which use of a PACS was reported had originated in North America (60%), Europe (22%), or Asia (14%). PACS were used in almost half of retrospective studies and in one-fourth of prospective studies (P < .01). A low correlation was found between utilization of PACS and use of other advanced technologies. CONCLUSION: Although PACS were utilized in the preparation of a substantial proportion of articles published in the two major radiology journals, there was a great disparity in the rate of PACS use among world regions. The proportion of studies originating in North America for which a PACS was used was nearly three times the number of similar studies originating in Europe, and more than four times the number originating in Asia.

[Status of international radiological publications and archive utilization in Turkey].

PURPOSE: To investigate the use of radiological technology and archive utilization in two sampled international radiological journals and radiology clinics in Turkey, and to explore the impact of these findings on radiological publications. MATERIALS AND METHODS: Randomly selected 22 issues of AJR and Radiology, 1037 articles in total, were reviewed. The type of article, radiological technique, country of origin, use of advanced technology and archiving were defined for each article. Additionally, a questionnaire, investigating implementation of various radiological devices, archiving and their technical features, was posted to the chairmen of the radiology departments in Turkey. RESULTS: Most of the articles (61.4%) originated in US. Studies from Turkey constituted 0.9% of the articles. This ratio was 2% for France, which has almost the same population as Turkey. Magnetic resonance imaging was used in 27.4% of cases. Based on our definition criteria, advanced technology and archiving were used in 19% and 32%, respectively. Data returns of the questionnaire were obtained from 17 of 45 (38%) radiology clinics. Responding clinics had conventional radiography, B mode ultrasound and conventional computed tomography. Archiving of all radiological examinations, excluding plain radiography, was performed in one center while only interesting radiological images and variations were stored in 8 departments. Implementation of archiving was reported sufficient in three clinics, partly sufficient in ten clinics and insufficient in four clinics. Archiving was performed by medical doctors in most of the cases (53%). The leading problems of archiving were technical and economical insufficiencies (82%). CONCLUSION: Archiving is more commonly required than utilization of advanced technology for international radiological publications. The rate of articles originating from Turkey was lower compared to some countries having the same population as Turkey. The lack of sufficient technical infrastructure and shortage of staff may be important reasons for such differences.
