One major objective of these guidelines is to prevent serious and/or harmful events in the course of disease. From a process analysis standpoint, such events are considered “errors” and should be investigated in accordance with the guidelines and tools for accident investigation. These tools include Process Mapping, Root-Cause Analysis, Influence Diagrams and Predictive Modeling methodology. The underlying principle is that all biologic environments are complex environments, involving a multitude of individual processes following multiple pathways and under the influence of numerous factors at multiple levels; as opposed to a single-axis main process line of the Ishikawa diagram. Process mapping mandates a thorough understanding of the multi-linear, inter-dependent and overlapping pathways involved in the genesis and maintenance of disease. Through this approach, the impact of various factors on the end-result can be more adequately assessed. More robust utilization of registry data is essential for comprehensive and complete data collection and organization. A probability-based predictive model may be best suited to incorporate all relevant factors, including others recognized in the future.","PeriodicalId":89580,"journal":{"name":"Journal of biomedical graphics and computing","volume":"4 1","pages":"54"},"PeriodicalIF":0.0,"publicationDate":"2014-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5430/JBGC.V4N4P54","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71215442","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}

Aims : To audit PCN insertions undertaken in women in order to determine the outcome, complications and their management, the age distribution and causes/indications for the procedure. Methods : The PACS and the automated letter systems as well as the laboratory results of the patients were used to obtain the relevant data. Results : Two hundred and seventeen patients underwent 344 PCN insertions with 100% success, 19 patients had 30 complications. No significant hemorrhage developed with 0.9% moderates and minor hemorrhages which settled. There was no death and no severe sepsis. The ages ranged from 17 to 95 years. Nephrostomy tube blockage occurred in 11(3%) patients. The nephrostomy tube fell-out and were replaced in 7(2%). One case of UTI was encountered. There most common indications for the PCN insertions were urinary tract calculi, transitional cell carcinoma of bladder, cervical carcinoma, urosepsis, pyonephrosis, and pregnancy. Conclusions: PCN insertion can be carried out safely in women of all ages including very old patients. The complication rate in our experience is low. Radiology departments should have trained radiologists capable of inserting nephrostomies.","PeriodicalId":89580,"journal":{"name":"Journal of biomedical graphics and computing","volume":"4 1","pages":"31"},"PeriodicalIF":0.0,"publicationDate":"2014-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5430/JBGC.V4N4P31","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71215199","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}

To realize the continuous clinical use and performance improvement of CAD software, it is necessary to continuously collect data for supervised learning in practical use and to improve CAD software by retraining with the collected data. In this study, we investigated the performance improvement of cerebral aneurysm detection software based on retraining the classifier through a simulation-based study. Methods: We collected data for retraining during the practical use of our cerebral aneurysm detection software and retrained the classifier for false positive (FP) reduction using the collected data. The effect on improving the performance was compared by changing the number of training cases and the training algorithms. Results: The performance was improved significantly ( p < .05) by retraining using additional training cases. In contrast, there were no statistical differences in the performance upon retraining among the four training algorithms for boosting. The sensitivity at 3 FPs/case was improved from 81.5% to 89.5% by retraining with additional training cases. Conclusions: The performance of the software was effectively improved by adding training cases rather than by changing the training algorithm.","PeriodicalId":89580,"journal":{"name":"Journal of biomedical graphics and computing","volume":"10 28 1","pages":"12"},"PeriodicalIF":0.0,"publicationDate":"2014-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5430/JBGC.V4N4P12","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71215138","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}

PET/CT imaging performed for staging and restaging in 36 and 103 patients,respectively. At least one conventional imaging (CI) as CT and/or MRI was performed for each one of the total patients.PET/CT studies revealed 66 true positive, 72 true negative, 4 false positive and 4 false negative results whereas the samevalues for CI were 65, 64, 4 and 6, respectively. When all studies were analyzed on the basis of lesion for PET/CT, specificity was 94.7%, and sensitivity being 94.2%,where as corresponding values for conventional imaging methods were found 94.1% and 91.5% respectively.
