To determine the prevalence and characterise the significance of incidental findings on whole-body MRI in paediatric and adult populations.
A retrospective, single-institution study over a period of 8 years. The study population comprised 325 paediatric (0-18 yrs) patients and 148 adults (19-40 yrs) referred to a specialist musculoskeletal oncology centre, who underwent whole-body MRI for a range of pathological indications. Incidental findings were recorded according to pathology (musculoskeletal or non-musculoskeletal), site and clinical relevance.
Eighty-seven of 325 (26.8 %) paediatric patients and 51 of 148 (35.8 %) adults had incidental findings detected on whole-body MRI. The most common site was the musculoskeletal system, and within this location the lower limbs. Eighty-nine percent of incidental findings in paediatric patients and 79 % of incidental findings in adults were classified as being of either minor or no clinical significance.
Incidental findings are common in paediatric and adult patients undergoing whole-body MRI, and are most frequently found in the lower limbs. The overwhelming majority are of minor clinical significance.
确定儿科和成人人群全身MRI偶然发现的患病率并描述其意义特征。
一项为期8年的单机构回顾性研究。研究人群包括325名儿科（0 - 18岁）患者和148名成人（19 - 40岁），他们因一系列病理指征被转诊至专业肌肉骨骼肿瘤中心并接受全身MRI检查。根据病理（肌肉骨骼或非肌肉骨骼）、部位和临床相关性记录偶然发现。
325名儿科患者中有87名（26.8%）、148名成人中有51名（35.8%）在全身MRI检查中发现偶然发现。最常见的部位是肌肉骨骼系统，在此部位中下肢最为常见。儿科患者中89%的偶然发现和成人中79%的偶然发现被归类为具有较小或无临床意义。
偶然发现在接受全身MRI检查的儿科和成人患者中很常见，且最常出现在下肢。绝大多数具有较小的临床意义。
