No study in the paediatric literature--and only a single study in all of the literature--has evaluated the visualization frequency of the sinus tarsi ligaments on MRI. That 20-year-old study demonstrated only limited visualisation.
The objective of this study is to re-evaluate the visualisation frequency of the sinus tarsi ligaments and to characterise their morphology on isotropic three-dimensional proton density imaging (3-D-PD). The authors hypothesise that by using 3-D-PD, these ligaments will be able to be demonstrated in nearly all paediatric patients.
Patients were scanned on either 1.5- or 3-Tesla scanners using 3-D-PD. Of 174 patients reviewed, 50 were identified who met inclusion and exclusion criteria.
The interosseous talocalcaneal ligament (ITC), the cervical ligament (CL) and the roots of the inferior extensor retinaculum (IER) were successfully visualised and characterised in three planes in 50 out of 50 children. The mean ligament thickness was 4.22 mm for the ITC, 2.74 mm for the CL and 1.04 mm for the IER roots.
With modern parameters, the tarsal sinus ligaments can be visualised in 100% of patients, a percentage substantially higher than previously reported.
在儿科文献中——以及所有文献中只有一项研究——评估了 MRI 中跗骨窦韧带的可视化频率。那项 20 年前的研究仅显示了有限的可视化。
本研究旨在重新评估跗骨窦韧带的可视化频率，并对各向同性三维质子密度成像（3-D-PD）中的形态进行特征描述。作者假设通过使用 3-D-PD，这些韧带几乎可以在所有儿科患者中显示出来。
患者使用 3-D-PD 在 1.5-T 或 3-T 扫描仪上进行扫描。在回顾的 174 名患者中，确定了 50 名符合纳入和排除标准的患者。
50 名儿童中有 50 名成功地在三个平面上观察到并描述了骨间跟距韧带（ITC）、颈韧带（CL）和下伸肌支持带的根（IER）。ITC 的平均韧带厚度为 4.22mm，CL 的平均韧带厚度为 2.74mm，IER 根的平均韧带厚度为 1.04mm。
在现代参数下，100%的患者可以观察到跗骨窦韧带，这一比例明显高于之前的报道。
