ABSTRACT
PURPOSE: The aim of this study is to determine the impact of a simulation-based ultrasound-guided (USG) breast biopsy training session on radiology trainee procedural knowledge, comfort levels, and overall procedural confidence and anxiety. METHODS: Twenty-one diagnostic radiology residents from a single academic institution were recruited to participate in an USG breast biopsy training session. The residents filled out a questionnaire before and after the training session. Ten multiple-choice questions tested general knowledge in diagnostic breast ultrasound and USG breast biopsy concepts. Subjective comfort levels with ultrasound machine and biopsy device functionality, patient positioning, proper biopsy technique, image documentation, needle safety and overall procedural confidence and anxiety levels were reported on a 5-point Likert scale before and after training. RESULTS: Participants demonstrated significant improvement in number of correctly answered general knowledge questions after training (P < .0001). Significant improvement was seen in resident comfort level in ultrasound machine functionality, patient positioning, biopsy device functionality, biopsy technique, image documentation, as well as overall confidence level (all P < .05). Participants indicated a slight but not significant reduction in anxiety levels (P = .27). CONCLUSIONS: A simulation-based USG breast biopsy training session may improve radiology trainee procedural knowledge, comfort levels, and overall procedural confidence.

OBJECTIVE: The purpose of this article is to determine whether formal instruction regarding the BI-RADS ultrasound lexicon results in improved appropriate use of the lexicon. MATERIALS AND METHODS: Ninety test questions depicting the features outlined by the 2003 BI-RADS lexicon were identified in our PACS. Informed consent was obtained from 34 radiology residents. The participants took the preinstruction test and then had 1 hour of formal instruction regarding the BI-RADS ultrasound lexicon, which included images depicting the different sonographic features and final assessment (including subcategories 4a, 4b, and 4c). The participants then completed the postinstruction test, which examined the same content. Test scores were calculated for both the pre- and postinstruction tests and then were compared by a linear mixed model and Wilcoxon signed rank tests. RESULTS: The participants' postinstruction test scores showed significant improvement in the overall use of the BI-RADS ultrasound lexicon (p < 0.0001). There was also significant improvement in the following specific areas: final assessment (p = 0.0005), margin (p = 0.0003), orientation (p = 0.0104), and lesion boundary (p = 0.0050). The categories for which test scores did not show significant improvement were echo pattern (p = 0.07), posterior acoustic features (p = 0.50), shape (p = 0.98), and subset of the final assessment (p = 0.24). CONCLUSION: Formal instruction regarding the BI-RADS ultrasound lexicon results in improved lesion characterization and final assessment.

Magnetic susceptibility and EPR studies show that trinuclear Cu(II)-pyrazolato complexes with a Cu(3)(mu3-X)2 core (X = Cl, Br) are ferromagnetically coupled: J(Cu-Cu) = +28.6 cm(-1) (X = Cl), +3.1 cm(-1) (X = Br). The orderly transition from an antiferromagnetic to a ferromagnetic exchange among the Cu centers of Cu(3)(mu3-X) complexes, X = O, OH, Cl, Br, follows the change of the Cu-X-Cu angle from 120 degrees to approximately 80 degrees. The crystal structures of [Bu4N]2"[Cu3(mu3-Br)2(mu-pz*)3Br3] (pz* = pz (1a) or 4-O2N-pz (1b), pz = pyrazolato anion, C(3)H(3)N(2)(1-)) are presented.
