A test predictive of ultimate radiologic expertise could be of great value in the selection of individuals entering the field. Some individuals have an aptitude superior to others to perceive three-dimensional spatial relations from two-dimensional data. This may enhance their ability to draw radiologic conclusions from clinical images and may favorably affect their performance as radiologists. To test cognitive perceptual ability, a three-dimensional Visual Form Reconstruction Test (form test) was developed and administered to residents and faculty members. All subjects also completed the Thurstone Surface Development Test, a standardized test of spatial visualization ability. The form test results correlated well with resident performance, as measured by overall faculty ratings (predictive validity). Although form test and Thurstone test performance were highly correlated with each other (concurrent validity), the form test was better correlated with resident performance. Intercorrelations among the three subsections of the form test demonstrated high split-part reliability. Performance on the form test was unaffected by level of training. This suggests that an underlying aptitude was measured. These preliminary results indicate that testing of spatial visualization aptitude is predictive of resident performance in radiology. A test such as this could be useful in selection and self-selection of resident candidates.
一种能够预测最终放射学专业技能的测试，对于选拔进入该领域的人员可能具有巨大价值。有些人从二维数据中感知三维空间关系的能力优于其他人。这可能会增强他们从临床图像得出放射学结论的能力，并可能对他们作为放射科医生的表现产生积极影响。为了测试认知感知能力，开发了一种三维视觉形式重建测试（形式测试），并对住院医师和教员进行了测试。所有受试者还完成了瑟斯顿表面发展测试，这是一种空间可视化能力的标准化测试。形式测试结果与住院医师的表现密切相关，以教员的总体评分来衡量（预测效度）。虽然形式测试和瑟斯顿测试的表现彼此高度相关（同时效度），但形式测试与住院医师的表现相关性更好。形式测试三个子部分之间的相互关联显示出较高的分半信度。形式测试的表现不受培训水平的影响。这表明测量到了一种潜在的能力倾向。这些初步结果表明，空间可视化能力倾向测试可预测住院医师在放射学方面的表现。这样的测试在住院医师候选人的选拔和自我选拔中可能会很有用。
