[en] Pulmonary artery coarctation is a rare congenital anomaly characterized by single or multiple stenoses of the pulmonary arteries and their branches. There are only a few reports describing the radiological film of this entity. In this paper we report the case of a 68 year-old woman who presented with dyspnea. The scintigraphic, examination of the lungs gave the misleading impression of pulmonary embolism, and only angiography and magnetic resonance imaging established the correct diagnosis of multiple coarctations of the pulmonary artery

[en] Objective: To compare the efficacy of dynamic contrast-enhanced MR imaging and spin-echo T1-weighted with and without fat-saturated MR imaging in the detection and staging of pancreatic adenocarcinoma. Methods and material: Spin-echo T1-weighted, fat-saturated T1-weighted and dynamic breath-hold 2D-FLASH MR imaging were performed in 25 patients with pancreatic adenocarcinoma. MR images were analysed by calculating the CNR between tumor and normal portion of the pancreas. The CNRs calculated at each sequences were compared. A total of 16 out of 25 patients underwent surgery. Preoperative staging according to TNM classification was also done in patients undergoing surgery. Results: The CNR was significantly different (P<0.05) in the arterial phase of dynamic MR images. The accuracy of 'T' staging was 75% for SE T1-W, fat-saturated T1-W and arterial phase of dynamic MR images. Conclusion: The CNRs between pancreatic carcinoma and normal pancreas is significantly higher in dynamic MR sequences than the SE T1-W, fat-saturated T1-W sequences. However, the accuracy of tumor staging according to TNM is equivocal to SE T1-W and fat-saturated T1-W images

[en] The aim of this study was to investigate the rate at which abstracts orally presented at the ESGAR 2000 and 2001 meetings were published between 2000-2004, and to identify predictive factors of publication. The abstracts of ESGAR meeting presentations were reviewed and classified according to organ, modality, type of design, country of origin of the studies and basic categories of diagnostic or interventional. The presentations were searched for publication in Medline-indexed journals using the PubMed server. The publication rates of the presentations, the time period between the presentation and publication, and the journal in which the article had appeared were investigated. An overall number of 109 publications were found originating from 276 presentations (39.5%). The median and inter-quartile range [IQR] between the abstract presentation and subsequently full publication was 18 months [1.0 -53.0]. The journal with the highest number of derived articles from abstract presentation was European Radiology (n=21, 19.2%). Retrospective studies were found to be more frequently published than prospective studies (p=0.001). The publication rate did not show any statistically significant difference between groups of other classifications. The publication rate of studies orally presented at ESGAR meetings was 39.5%. No specific variable other than the type of design of the studies appeared to influence the publication rate. (orig.)

[en] To evaluate the frequency of mobile technology and social media usage among radiology residents and their access to professional information. A questionnaire consisting of 24 questions prepared using Google Drive was sent via e-mail to 550 radiology residents throughout the country. Of the 176 participating residents, 74 completed the survey via the internet, and 102 completed it at three different national radiology meetings. Response rates and its relationship with responses given to different questions were assessed. Hundred two male and 74 female residents participated in the survey. 141 (81.3%) residents thought that they had appropriate internet access in their department. The number of residents using a smartphone was 153 (86.9%). The android operating system (70, 45.8%) was the preferred operating system of respondants. Only 24 (15.7%) of the smartphone users thought that there were enough radiology related applications. “Radiology assistant” (18.9%), “Radiopedia” (7.8%) and “Radiographics” (7.8%) were the most utilized applications. Of the smartphone users, 87(56.9%) stated that they used cell phones in order to find radiological information, and the most used web pages were Google (165, 93.8%), Radiopaedia.org (129, 73.3%), Radiologyassistant.nl (135, 76.7%), and Pubmed (114, 64.8%). Social media usages were as follows: None (10, 5.7%), Facebook (139, 79%), Twitter (55, 31.3%), Google + (51, 29%) and YouTube (44, 25%). While smartphone usage rates among the residents were high, the use of radiology specific applications was not common. Social media usage was very common among residents

[en] Congenital 'true' splenic cysts are rare lesions. Therapeutic methods for the management of these lesions have been based on preserving splenic function due to the immunologic role of spleen. We report three different cases of congenital splenic cysts treated by percutaneous drainage and polidocanol sclerotherapy. This less invasive treatment appears to be safe and effective after 6 to 36 months of follow-up
