Elastofibroma dorsi (ED) is a rare soft-tissue tumour. Diagnosis is made using imaging, mainly magnetic resonance due to its higher sensitivity and specificity in soft tissues. No agreement exists when deciding which imaging test must be used. Often multiple tests are made in the same patient, increasing time and costs. The aim of this paper is to compare the usual imaging exams and evaluate which one is the most accurate when diagnosing and measuring ED.
A retrospective review was made of those patients who were diagnosed and operated for ED since January 2006 to December 2013. Fifty-two ED were included (19 men, 25 women), and eight of them were bilaterally affected. They were divided into three different groups according to the imaging test used: ultrasound (US) computed tomography (CT) and magnetic resonance (MR). After surgery the pieces were sized and compared with the measurements made by imaging exams.
Two hundred fourteen measures were analysed (40 US, 33 CT and 34 MR with their pathological equivalent). When CT group and its corresponding AP were analysed, no significant differences between them were founded (p > 0.05). Moreover, we analysed absolute differences between measures. In the US group a mean difference of 2.23 ± 1.87 cm was obtained. In the CT group, the mean difference was 1.22 ± 0.97 cm. Likewise, the difference of the MR group was 1.62 ± 1.15 cm.
This study demonstrates that the CT obtains a higher correlation than MR when determining the size of ED.
背部弹力纤维瘤（ED）是一种罕见的软组织肿瘤。诊断主要依靠影像学检查，由于磁共振成像在软组织中具有更高的敏感性和特异性，因此常被使用。在决定使用哪种影像学检查时，尚无统一标准。同一患者常需进行多项检查，这增加了时间和成本。本文旨在比较常用的影像学检查方法，并评估在诊断和测量ED时哪种方法最准确。
回顾性分析2006年1月至2013年12月期间诊断为ED并接受手术的患者。纳入52例ED患者（男性19例，女性25例），其中8例为双侧受累。根据所使用的影像学检查方法将患者分为三组：超声（US）、计算机断层扫描（CT）和磁共振成像（MR）。手术后对标本进行测量，并与影像学检查测量结果进行比较。
共分析了214次测量结果（40次超声、33次CT和34次MR及其病理对应结果）。分析CT组及其相应的病理结果时，未发现显著差异（p>0.05）。此外，我们分析了测量结果之间的绝对差异。超声组的平均差异为2.23±1.87cm。CT组的平均差异为1.22±0.97cm。同样，磁共振成像组的差异为1.62±1.15cm。
本研究表明，在确定ED大小时，CT与病理结果的相关性高于磁共振成像。
