| 中文摘要: |
| 目的：分析腺泡状软组织肉瘤的影像学表现。方法：回顾性分析11例腺泡状软组织肉瘤的影像学表现。结果：腺泡状软组织肉瘤的MRI主要表现为T1加权成像上等或稍高信号，T2加权成像上混杂高信号。腺泡状软组织肉瘤内多见扭曲的流空信号或“线样”低信号分隔。肿瘤呈不均匀明显强化。1H-MRS上，在3.2ppm处，会出现一个稍高的胆碱峰。结论：腺泡状软组织肉瘤主要影像学诊断特点为边界规整、富血液流空、“线样”低信号分隔。并且，胆碱峰增高可以作为一项重要的辅助诊断指标。 |
| 英文摘要: |
| Objective?The aim of this study was to analyze the imaging features of alveolar soft part sarcoma (ASPS).
Methods?The imaging features of 11 cases with ASPS were retrospectively analyzed.
Results?ASPS mainly exhibited an isointense or slightly high signal intensity on T1-weighted imaging (T1WI), and a mixed high signal on T2-weighted imaging (T2WI). ASPS was partial, with rich tortuous flow voids, or “line-like” low signal septa. The essence of the mass was heterogeneous enhancement. The 1H-MRS showed a slight choline peak at 3.2 ppm.
Conclusion?The well-circumscribed mass and blood voids, combined with “line-like” low signals play a significant role in diagnosis. The choline peak and the other signs may be auxiliary diagnoses.
