Materials and Methods: The study was approved by an institutional review board and was HIPAA compliant; informed consent was obtained. This study included residents, with 16 in the control group and 18 in the intervention group. For phase 1, each subject reviewed the same set of 25 brain MR imaging cases and dictated the cases by using free-text conventional dictation. For phase 2, 4 months later, the control group repeated the same process, whereas the intervention group reread the same MR imaging cases by using SRS to create reports. Resident-generated reports were graded for accuracy and completeness by a neuroradiologist on the basis of consensus
interpretations and criterion standard diagnoses as Dorsomorphin ic50 established with at least 6 months of clinical follow-up, imaging follow-up, and/or histologic examination where appropriate. Accuracy and completeness scores were analyzed by
using a Wilcoxon signed rank test for paired data and a Mann-Whitney U test for nonpaired data. Intervention group residents were surveyed regarding their opinions of SRS.
Results: For phase 1 reports, no significant difference in accuracy or completeness scores between control and intervention groups was found. Decreases in accuracy (91.5 to 88.7) and completeness (68.7 to 54.3) scores for phase 2 compared with phase 1 for the intervention group were found; increases in accuracy (91.4 to 92.4) and completeness (67.8 to 71.7) scores for phase 2 compared with phase 1 for the control group were found (all P values < .001). The most common complaints were that the SRS was overly constraining with regard to report content and P005091 nmr was time-consuming to use.
Conclusion: While there are many potential benefits of structuring radiology reports, such changes cannot be assumed to improve report accuracy or completeness. Any SRS should be tested
for effect on intrinsic report quality. (C) RSNA, 2009″
“We discuss the electron transport through a quantum Hall Fabry-Perot find more interferometer (QHFPI) obtained with two quantum point contacts (QPCs) in series along a ballistic quantum wire by focusing on the effects due to quantum interference and to quantum Hall effect. We calculate the conductance-energy and conductance-magnetic field characteristics as functions of the geometrical parameters and gate voltages. QHFPI may be utilized in designing electronic logic gates: XOR and OR (NOR and XNOR) gates responses are investigated. The width of each QPC is modulated by metallic electrodes where two gate voltages, namely, V(a) and V(b), are applied. Those external voltages are treated as the two inputs of the gates. After fixing appropriately the working Fermi energy, the magnetic field strength, and the distance between the barriers, a low output Hall current (0) (in the logical sense) appears just if both inputs are low (0), while a high output Hall current (1) results otherwise. It clearly demonstrates the OR gate behavior.
