To determine prevalence in the symptomatic population of dorsal mucoid cysts centered on dorsal capsuloscapholunate septum (DCSS) using high-field magnetic resonance imaging (MRI) for anatomoclinical and epidemiological correlations.
This single-center retrospective study analyzed all 3-Tesla MRIs consecutively performed for painful wrists in 295 patients. Two blinded readers performed measurements. The protocol included T1 spin echo and 3D proton density sequences with fat saturation. Inter-observer reliability was assessed using kappa and intra-class correlation coefficients for cyst detection and volumetry, respectively. Disagreements concerning cyst detection were resolved by a consensus reading. Cyst size, relationship to extrinsic and scapholunate ligaments (SL), continuity of SL, minimum distance to the posterior interosseous nerve (PIN), cyst communication with joint, and anatomical classifications of cysts were analyzed. Correlation tests were performed to assess associations.
Two-hundred ninety-five patients (mean age 39.6 +/- 15.6 (standard deviation), 161 males) were evaluated for detection of dorsal wrist cysts identified in 150/295. In this subgroup, the mean age was 38.7 years (15-75), the sex ratio of 0.6 (59% women), and the median volume cyst of 8.7 mm (0.52-2555). Cyst detection, volume, and major axis measurements showed very high agreement between observers, respectively, 0.89, 0.96, and 0.91. 42 patients had dorsal SL pain. A weak negative correlation was found between distance to PIN and dorsal SL pain (r = -0.2415; p < 0.05) and a weak positive correlation between Guérini's classification and dorsal SL pain (r = 0.2466; p < 0.05).
High-field MRI is the modality of choice for the detection, anatomical, and volumetric assessment of dorsal cysts. Preoperative assessment will be aided by the proposed revised anatomical classification.
High-field MRI is the modality of choice for the anatomical study of dorsal ganglion cysts. It allows the radiologist to accurately describe the anatomical relationships, size, and visibility of the pedicle, essential information for the surgeon's preoperative assessment.
Dorsal mucoid wrist ganglion is a condition for which prevalence remains to be determined. High-field MRI is a reproducible imaging modality for the detection and assessment of dorsal wrist cysts. High-field MRI has a key role in the preoperative management of dorsal mucoid cysts.
使用高磁场磁共振成像（MRI）确定以背侧 capsuloscapholunate 隔（DCSS）为中心的有症状人群中背侧粘液囊肿的患病率，进行解剖学-临床和流行病学相关性分析。
这是一项单中心回顾性研究，对 295 例因腕部疼痛而连续进行的 3-Tesla MRI 进行了分析。两位盲法读者进行了测量。该方案包括 T1 自旋回波和 3D 质子密度序列，带有脂肪饱和。分别使用kappa 和组内相关系数评估囊肿检测和容积测量的观察者间可靠性。通过共识阅读解决囊肿检测方面的分歧。分析了囊肿的大小、与外在和舟月韧带（SL）的关系、SL 的连续性、与后骨间神经（PIN）的最小距离、囊肿与关节的连通性以及囊肿的解剖学分类。进行相关测试以评估关联。
对 295 例患者（平均年龄 39.6 +/- 15.6[标准差]，161 例男性）进行了背侧腕部囊肿的检测，在这一亚组中，平均年龄为 38.7 岁（15-75 岁），性别比例为 0.6（59%女性），囊肿体积中位数为 8.7 mm（0.52-2555）。囊肿检测、体积和长轴测量的观察者间具有非常高的一致性，分别为 0.89、0.96 和 0.91。42 例患者有背侧 SL 疼痛。发现到 PIN 的距离与背侧 SL 疼痛之间存在弱负相关（r = -0.2415;p < 0.05），Guérini 分类与背侧 SL 疼痛之间存在弱正相关（r = 0.2466;p < 0.05）。
高磁场 MRI 是检测、解剖和评估背侧囊肿的首选方法。提出的新解剖分类将有助于术前评估。
高磁场 MRI 是背侧神经节囊肿解剖研究的首选方法。它使放射科医生能够准确描述蒂的解剖关系、大小和可见性，这是外科医生术前评估的重要信息。
背侧粘液性腕部神经瘤是一种患病率尚待确定的疾病。高磁场 MRI 是一种用于检测和评估背侧腕部囊肿的可重复成像方式。高磁场 MRI 在背侧粘液性囊肿的术前管理中具有关键作用。
