Long-term drainage of the obstructed upper urinary tract may be achieved by percutaneous nephrostomy or ureteric stenting. Previously most ureteric stents were inserted by the retrograde approach at cystoscopy and these procedures have required the use of general or spinal anesthesia. With the development of a nephrostomy service in most hospitals throughout the world ante-grade ureteric stenting procedures are being carried out by trained interventional radiologists in the radiology department without the need for a general or spinal anesthesia. Aims/materials and methods : To review the records of all 89 patients who had insertion of ante-grade ureteric stents for ureteric obstruction between February 2010 and January 2013 in order to document the following: The causes of obstruction; The side (left, right or both sides) and site of the ureteric obstruction (upper, mid or lower ureter); The sex and ages of the patients; Success or failure of the procedure; Complications of procedure; The management of the complications. Results : Ante-grade ureteric stenting was successful in 105 out of 121 procedures (86.7%) which 89 patients underwent. Out of 105 successful ante-grade stenting procedures carried out, 103 were successful at first attempt, another two were successful at second attempt and one successful at a third attempt, making it a total of 105 successful procedures. There were minimal complications. Conclusion and recommendation: Ante-grade ureteric stenting is a safe procedure with minimal complications. Every radiology unit should have a trained interventional radiologist capable of performing ante-grade ureteric stenting.","PeriodicalId":89580,"journal":{"name":"Journal of biomedical graphics and computing","volume":"4 1","pages":"47"},"PeriodicalIF":0.0,"publicationDate":"2014-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5430/JBGC.V4N3P47","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71214925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: Contrast Enhanced Computed Tomography (CECT) of chest done in supine position in inspiration with 60 to 120 ml of 300 mg/ml of nonionic iodinated contrast and images were viewed in lung window (level 700 HU; width 1,500 HU), mediastinal window (level 30 HU-50 HU; width 350 HU-500 HU) and bone window (level 2,400 HU; width 200 HU). Results: The most common compartment to be involved was anterior mediastinum (38.3%) followed by posterior (16.7%), middle (13.3%) and superior mediastinum (11.7%) in that order. Predominant lesions were benign. The commonest lesion was tubercular lymphadenopathy (15%). Thymic masses and metastatic lymph node (26% each) were the most common mediastinal lesions in the anterior mediastinal compartment. Neural tumors (50%), esophageal carcinoma (37.5%) and thyroid masses (85.7%) were the common lesions in posterior, middle and superior mediastinal compartments respectively.

Giovanna","doi":"10.5430/JBGC.V4N3P10","DOIUrl":"https://doi.org/10.5430/JBGC.V4N3P10","url":null,"abstract":"The control of food intake involves complex and powerful neural mechanisms whose functioning has critical repercussions for alimentary behaviours and the regulation of energy balance. Recent research also from cognitive neurosciences indicates that homeostatic (repletion-driven) and hedonic (reward-driven) systems in the brain concur in achieving an integrated regulation of human alimentary activity. Modern societal changes, related to unrestricted availability of energy-dense palatable foods at low costs and widespread presence of compelling alimentary cues, are considered to contribute to a food consumption driven mainly by hedonic properties rather than energy requirements, and result among the causes of worldwide obesity epidemics. Functional neuroimaging permits the exploration of the human brain systems involved under the different conditions of alimentary relevance, through the quantitative evaluation of regional blood flow, metabolic activation of defined cerebral networks or molecular bioavailability of brain receptors specifically traced. Such a framework of different imaging techniques appears uniquely suited to investigate the functional integration of the neural processes which underpin the interplay between homeostatic drive for feeding and the conscious experience of pleasure and reward concurring to the control of food intake. Therefore, these techniques provide an invaluable tool in gaining a detailed comprehension of physiology underlying alimentary behaviours and their derangements, and in detecting new strategies against obesity which interact also on brain mechanisms involved in the control of food intake and energy balance. In the present short review, basic principles of the most used functional neuroimaging techniques will be examined and the commonest acquisition protocols and processing methods will be briefly presented, along with a short overview of the brain systems involved in food intake regulation and a concise report of the main findings obtained with these techniques.","PeriodicalId":89580,"journal":{"name":"Journal of biomedical graphics and computing","volume":"4 1","pages":"10"},"PeriodicalIF":0.0,"publicationDate":"2014-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5430/JBGC.V4N3P10","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71215179","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this article, we summarize our experiences with using Google Glass in simulation-based training and discuss potential future directions with this advanced technology. Methods: Emergency medicine residents and medical students participated in a pilot study where each team captain was asked to wear Google Glass during 15 separate simulation-based training sessions. Video obtained from Google Glass was analyzed and utilized during debriefing sessions for the residents and medical students. Results: We were able to successfully integrate Google Glass into simulation-based training and debriefing. During the analysis of each recording, observations were noted about the events that transpired and this data was used to provide instructional feedback to the residents and medical students for self-reflection and appraisal. Post-exercise surveys were conducted after each simulation session and all participants noted that Google Glass did not interfere with their simulation experience. Google Glass enabled the observers to analyze the team captain’s primary visual focus during the entire simulation scenario and feedback was provided based on the data recorded. Conclusions: Wearable technologies such as Google Glass can be successfully integrated into simulation-based training exercises without disrupting the learners’ experience. Data obtained from this integration can be utilized to improve debriefing sessions and self-reflection.

It is implemented as a “second reader” to help radiologists focus their attention on regions that might be missed during visual interpretation. The proposed CAD system has three main stages; Segmentation by thresholding the CT images, labeling the founded regions and then extracting some diagnostic features of each region for further analysis and interpretation. The study is trained, tested, and validated using images obtained from forty five patients.

Aim of this study was to demonstrate the benefit of longitudinal strain analysis by 3D STE as compared to the established 2D STE techniques. Methods : 2D and 3D STE was performed in 30 volunteers with normal systolic left ventricular (LV) function using cardiac ultrasound systems from two different vendors (Vivid E9 and iE33 xMATRIX). Global and segmental longi - tudinal strain (GLS, SLS) values were analyzed for 2D STE using respective software packages (Vivid E9: EchoPAC AFI; iE33 xMATRIX: QLAB CMQ 9.0). Measurements for 3D STE were performed using specific software for Vivid E9 (EchoPAC 4DAutoLVQ) and unspecific software for iE33 xMATRIX (TomTec Imaging Systems 4D left ventricular Analysis). Intra-, interobserver and test-retest variability as well as times for acquisition and analysis were compared between 2D and 3D STE techniques. Results : The reliability of SLS measurements using 3D STE was non-inferior to the measurements obtained by 2D STE, with perpetual constant results in all tests (ICC SLS 3D 0.78 – 0.94 vs . SLS 2D 0.73 – 0.93). Agreements between SLS values were better when vendor specific 2D and 3D software was applied. GLS measurements showed inhomogeneous results for both techniques (ICC GLS 3D 0.40 – 0.93 vs . GLS 2D 0.13 – 0.91). Acquisition time was significantly shorter for 3D datasets than for 2D datasets (3D 51.0 ± 10.66 sec vs . 2D 91.0 ± 10.9 sec, p < .01). Conclusion : 3D STE is a time-saving technology for the evaluation of myocardial deformation in daily clinical practice, generating results that are comparable to the conventional 2D STE techniques. SLS obtained by 3D STE seems to be a more robust parameter than GLS for the assessment of myocardial deformation, especially when vendor specific software packages are used.","PeriodicalId":89580,"journal":{"name":"Journal of biomedical graphics and computing","volume":"4 1","pages":"23"},"PeriodicalIF":0.0,"publicationDate":"2014-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5430/JBGC.V4N2P23","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71215044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our aim was to determine if tumor growth during the interval between image acquisition and operative date impacted the observed size discrepancy. Methods: Tumor sizes measured on preoperative MRI were compared with gross pathological specimen measurements in 148 patients with surgically resected pancreatic adenocarcinoma. Differences in the measurements were correlated with the interval between date of pre-operative MRI acquisition and date of operation. Differences between tumor size on MRI and pathology reports were compared with respect to the intervening time interval. Results: A total of 148 patients had pre-operative MRI scans and were included in the analysis. The median patient age was 66 years (range: 29 years-86 years). A significant under estimation of 4.5 mm between tumor size measured on preoperative MRI and pathological examination ( p < .001) was demonstrated. There was no significant correlation between size discrepancy and time interval from the diagnostic imaging study and the surgical procedure (R 2 = 0.001, p = .72). Conclusions: Time interval between the acquired diagnostic imaging study and operative date appears to have no measureable influence on radiographic to pathologic size discrepancy in pancreatic adenocarcinoma. MRI was again shown to underestimate pancreatic cancer tumor size. Additional exploration into the role of MRI in delineating pancreatic tumor volume with a prospectively designed study is needed to validate these findings.","PeriodicalId":89580,"journal":{"name":"Journal of biomedical graphics and computing","volume":"4 1","pages":"15"},"PeriodicalIF":0.0,"publicationDate":"2014-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5430/JBGC.V4N2P15","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71215000","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
