Abstract

Background: The workload of musculoskeletal radiologists has come under pressure. Our objective was to estimate the reading times of common musculoskeletal MRI examinations.

Methods: A total of 144 radiologists were asked to estimate reading times (including interpretation and reporting) for MRI of the shoulder, elbow, wrist, hip, knee, and ankle. Multivariate linear regression analyses were performed.

Results: Reported median reading times with interquartile range (IQR) for the shoulder, elbow, wrist, hip, knee, and ankle were 10 (IQR 6-14), 10 (IQR 6-14), 11 (IQR 7.5-14.5), 10 (IQR 6.6-13.4), 8 (IQR 4.6-11.4), and 10 (IQR 6.5-13.5) min, respectively. Radiologists aged 35-44 years reported shorter reading times for the shoulder (β coefficient [β] = B-3.412, p = 0.041), hip (β = -3.596, p = 0.023), and knee (β = -3.541, p = 0.013) than radiologists aged 45-54 years. Radiologists not working in an academic/teaching hospital reported shorter reading times for the hip (β = -3.611, p = 0.025) and knee (β = -3.038, p = 0.035). Female radiologists indicated longer reading times for all joints (β of 2.592 to 5.186, p ≤ 0.034). Radiologists without musculoskeletal fellowship training indicated longer reading times for the shoulder (β = 4.604, p = 0.005), elbow (β = 3.989, p = 0.038), wrist (β = 4.543, p = 0.014), and hip (β = 2.380, p = 0.119). Radiologists with <5 years of post-residency experience indicated longer reading times for all joints (β of 5.355 to 6.984, p ≤ 0.045), and radiologists with 5-10 years of post-residency experience reported longer reading time for the knee (β = 3.660, p = 0.045) than those with >10 years of post-residency experience.

Conclusions: There is substantial variation among radiologists in reported reading times for common musculoskeletal MRI examinations. Several radiologist-related determinants appear to be associated with reading speed, including age, gender, hospital type, training, and experience.

常见肌肉骨骼 MRI 检查的读取时间：调查研究。

背景：肌肉骨骼放射科医生的工作量压力很大。我们的目的是估算常见肌肉骨骼核磁共振成像检查的读片时间：方法：我们要求 144 名放射科医生估算肩部、肘部、腕部、髋部、膝部和踝部 MRI 检查的读片时间（包括判读和报告）。进行了多变量线性回归分析：肩部、肘部、腕部、髋部、膝部和踝部报告的中位阅读时间（IQR）分别为10（IQR 6-14）分钟、10（IQR 6-14）分钟、11（IQR 7.5-14.5）分钟、10（IQR 6.6-13.4）分钟、8（IQR 4.6-11.4）分钟和10（IQR 6.5-13.5）分钟。与 45-54 岁的放射科医生相比，35-44 岁的放射科医生报告的肩部（β 系数 [β] = B-3.412，p = 0.041）、髋部（β = -3.596，p = 0.023）和膝部（β = -3.541，p = 0.013）的读片时间更短。不在学术/教学医院工作的放射科医生报告的髋关节（β = -3.611，p = 0.025）和膝关节（β = -3.038，p = 0.035）读片时间较短。女性放射医师表示所有关节的读片时间都更长（β 为 2.592 到 5.186，p ≤ 0.034）。没有接受过肌肉骨骼研究培训的放射科医生表示肩关节（β = 4.604，p = 0.005）、肘关节（β = 3.989，p = 0.038）、腕关节（β = 4.543，p = 0.014）和髋关节（β = 2.380，p = 0.119）的读片时间更长。p≤0.045）的放射科医生和有 5-10 年实习经验的放射科医生报告的膝关节读片时间（β = 3.660，p = 0.045）长于有 >10 年实习经验的放射科医生：结论：放射科医生报告的常见肌肉骨骼 MRI 检查的读片时间差异很大。与放射科医生相关的几个决定因素似乎与读片速度有关，包括年龄、性别、医院类型、培训和经验。

期刊介绍： TomographyTM publishes basic (technical and pre-clinical) and clinical scientific articles which involve the advancement of imaging technologies. Tomography encompasses studies that use single or multiple imaging modalities including for example CT, US, PET, SPECT, MR and hyperpolarization technologies, as well as optical modalities (i.e. bioluminescence, photoacoustic, endomicroscopy, fiber optic imaging and optical computed tomography) in basic sciences, engineering, preclinical and clinical medicine. Tomography also welcomes studies involving exploration and refinement of contrast mechanisms and image-derived metrics within and across modalities toward the development of novel imaging probes for image-based feedback and intervention. The use of imaging in biology and medicine provides unparalleled opportunities to noninvasively interrogate tissues to obtain real-time dynamic and quantitative information required for diagnosis and response to interventions and to follow evolving pathological conditions. As multi-modal studies and the complexities of imaging technologies themselves are ever increasing to provide advanced information to scientists and clinicians. Tomography provides a unique publication venue allowing investigators the opportunity to more precisely communicate integrated findings related to the diverse and heterogeneous features associated with underlying anatomical, physiological, functional, metabolic and molecular genetic activities of normal and diseased tissue. Thus Tomography publishes peer-reviewed articles which involve the broad use of imaging of any tissue and disease type including both preclinical and clinical investigations. In addition, hardware/software along with chemical and molecular probe advances are welcome as they are deemed to significantly contribute towards the long-term goal of improving the overall impact of imaging on scientific and clinical discovery.
