| 目的探讨彩色多普勒血流成像（CDFI）联合实时组织弹性成像（RTE）对腱鞘巨细胞瘤（GCTTS）的诊断价值。方法回顾性分析27例患者32个经病理证实为GCTTS病灶声像图特征。结果GCTTS以右侧手部发病最多；男女比为1颐2；病灶以局限型多见。声像图表现：肿块内部为低回声30个，无回声2个；内部回声均匀27个，不均匀5个；边界清晰28个，边界不清4个；形态规则14个，形态不规则18个；2个肿块内部伴有无回声区。CDFI示病灶内部血供Alder分级Ⅱ~Ⅲ级占62.5%（20/32），以Ⅲ级居多；RTE评分≤3分占84.4%（27/32），且发现病灶内部血供Alder分级与RTE评分间呈正相关（rs=0.66，P＜0.05）。误诊率为25.0%。结论CDFI联合RTE诊断GCTTS，有助于提高诊断准确率，可推荐为首选检查方法。 |

| Abstract: |
| Objective To assess the value of color Doppler flow imaging (CDFI) combined with real-time tissue
elastography (RTE) in diagnosis of giant cell tumor of tendon sheath (GCTTS). Methods The features of CDFI and RTE of 27 patients with GCTTS (32 lesions) were retrospective analyzed. Results Most of the lesions were of topical type and located in right hands with a male/female ration of 1 颐2. The ultrasound image showed low echo in 30 masses and no echo in 2 masses, homogeneous echo in 27 masses and uneven in 5 cases, clear border in 28 masses and unclear boundaries in 4 tumors, regular
shape in 14 tumors and irregular in 18, and tumors with no echoic area in 2 cases. According to the Alder classification, the Ⅱ~Ⅲ
levels accounted for 62.5% in CDFI. According to the RTE scoring system, 84.4% was ≤3. There was a linear correlation between internal blood supply and RTE (rs=0.66, P＜0.05). The misdiagnosis rate was 25.0%. Conclusion CDFI combined with RTE is recommended as the first choice in the diagnosis of giant cell tumor of tendon sheath. |
