For each unknown case, eight similar images of benign lesions and eight similar images of malignant lesions were preselected with a computerized scheme. From these preselected images, a breast radiologist subjectively selected the four most similar images of benign lesions
and the four most similar images of malignant lesions. Five attending breast radiologists and three breast-imaging fellows participated in the observer study. Observers provided their confidence level regarding malignancy of the unknown case before and after they viewed the similar images. The results were evaluated with multireader multicase receiver operating characteristic (ROC) analysis.
Results: For all observers, the areas under the ROC curves (AUCs) were improved when similar images were used. The LBH589 order average AUC for all observers increased from 0.692 without use of similar images to 0.790 with use of similar images (P = .0009).
Conclusion: The presentation
of similar images can improve radiologists’ performance in the differential diagnosis of clustered microcalcifications on mammograms. (C) RSNA, 2009″
“Objective: Anastomosis of ureteropelvic junction with a laparoscope for the treatment of ureteropelvic junction obstruction (UPJO) is a time-consuming and technically challenging procedure. We present our experience of laparoscopic dismembered pyeloplasty and compare clinical outcomes of two different suture techniques. Methods: From September 2003 AZD1208 price to June 2010, 105 laparoscopic dismembered pyeloplasties were performed in our department. All procedures
were done using the retroperitoneal approach. According to the suture methods (interrupted or running), the patients were divided into two groups. An indwelling XMU-MP-1 cell line stent was placed intraoperatively in an antegrade manner. Data on operation time, blood loss and complications were collected. Results: All procedures were completed without open conversion. Mean operation time and anastomotic time were 96 (55-150) and 36 min (15-70), respectively. A significant decrease of operation and anastomosis time was seen when running sutures were applied. Mean blood loss was 54 ml (30-100). The total complication rate was 7.6%. No anastomotic stricture occurred. The average hospitalization stay was 7 days. During 5-85 months of follow-up, hydronephrosis was alleviated in all cases. Conclusions: Laparoscopic dismembered pyeloplasty for the treatment of UPJO can provide satisfactory clinical outcomes. Higher surgical efficiency and lower complication rates can be obtained by using the running suture method. Copyright (C) 2011 S. Karger AG, Basel”
“Purpose: To examine changes in screening mammogram interpretation as radiologists with and radiologists without fellowship training in breast imaging gain clinical experience.
