Physicians write child abuse forensic reports for nonphysicians. We examined 73 forensic reports from a Canadian children's hospital for recurrent strategies geared toward making medical information accessible to nonmedical users; we also interviewed four report writers and five readers. These reports featured unique forensic inserts in addition to headings, lists, and parentheses, which are typical of physician letters for patients. We discuss implications of these strategies that must bridge the communities of medical, social, and legal practice. 相似文献

A discriminant method for optimizing activity in nuclear medicine studies is validated by comparison with ROC (received operating characteristic)-curves. The method is tested in 21 single photon emission computerized tomography (SPECT), performed with a cardiac phantom. Three different lesions (Lb L2 and L3) were placed in the myocardium-wall by pairs fbr each SPECT. Three activities (84, 37 or 18.5 MBq) of 99mTc were used as background. Linear discriminant analysis was used to select the parameters that characterize image quality among the measured variables in the images [(Background-to-Lesion (B/Li) and Signal-to-Noise (S/N) ratios)]. Two clusters with different image quality (P=0.021 ) were obtained. The ratios B/Lj, B/L2 and B/L3 are the parameters used to construct the function with 100% of cases correctly classified into the clusters. The value of 37 MBq was the lowest tested activity for which good results for the B/Li ratios were obtained. The result coincides with the applied ROC-analysis (r=0.89). 相似文献
