The aim of this study was to evaluate the magnetic resonance imaging (MRI) interpretation proficiency of musculoskeletal fellows in training.
Between July 2003 and June 2007, 14 musculoskeletal fellows were independently tested with 20 MRI studies of the knee and shoulder at four separate time points during their fellowship years. Trends in true-positive and false-positive interpretation results were evaluated. Fellows who completed their residencies at the fellowship institution (internal fellows) were compared with those from other residencies (external fellows).
There was a significant improvement in proficiency between the initial and final (9-month) evaluations (P < .0001). At the initial evaluation, there was a mean of 52.8% (41.7 of 79) true-positive results (range, 32-51); at 9 months, there was a mean of 71.0% (56.1 of 79; range, 40-72). The number of false-positive results also declined during this time period from a mean of 8.1 (range, 2-13) at initial evaluation to 4.7 (range, 2-8) at 9 months (P < .001). External fellows had more incorrect diagnoses initially but showed greater improvement than internal fellows at 9 months.
Fellows continued to improve their MRI interpretation skills throughout the first 9 months of their fellowships. External fellows were slightly less proficient at the start of their fellowships but slightly more proficient at 9 months compared to internal fellows.
本研究旨在评估接受培训的肌肉骨骼专业进修医师的磁共振成像（MRI）解读能力。
在2003年7月至2007年6月期间，14名肌肉骨骼专业进修医师在其进修期间的四个不同时间点，独立接受了20项膝关节和肩关节的MRI检查。对真阳性和假阳性解读结果的趋势进行了评估。将在进修机构完成住院医师培训的进修医师（内部进修医师）与来自其他住院医师培训项目的进修医师（外部进修医师）进行了比较。
在初始评估和最终（9个月）评估之间，能力有显著提高（P <.0001）。在初始评估时，真阳性结果的平均比例为52.8%（79项中的41.7项）（范围为32 - 51）；在9个月时，平均比例为71.0%（79项中的56.1项；范围为40 - 72）。在此期间，假阳性结果的数量也从初始评估时的平均8.1项（范围为2 - 13）下降到9个月时的4.7项（范围为2 - 8）（P <.001）。外部进修医师最初的误诊较多，但在9个月时比内部进修医师有更大的进步。
进修医师在其进修的前9个月中，其MRI解读技能持续提高。外部进修医师在进修开始时能力略低，但在9个月时比内部进修医师略高。
