摘　　要：目的探讨弥散成像技术在软组织恶性肿瘤和炎症性病变鉴别中的应用价值。方法回顾性分析19例软组织恶性肿瘤和16例软组织脓肿常规MRI及弥散成像表现,测量ADC值,并进行两组间比较。结果脓肿在b值600s/mm2弥散序列成高信号12例,混杂信号4例,肿瘤呈高信号15例,混杂信号4例,恶性肿瘤组ADC值低于脓肿组,两组间比较有统计学差异。结论软组织弥散成像结合常规序列可以帮助鉴别软组织恶性肿瘤和软组织脓肿。Objective To study the diffusion-weighted imaging technology to identify soft tissue tumors and inflammatory lesions to identify the value. Methods A retrospective analysis of 19 cases of soft tissue malignant tumor and 16 cases of soft tissue abscesses with conventional MRI and diffusion-weighted imaging performance, measuring the ADC value, and between the two groups. Result Abscess in the b value of 600 diffusion sequence into a high signal in 12 cases, and other signals of four cases, the tumors were 15 cases of high signal, such as signal 4 cases of malignant tumor ADC value lower than the abscess group, there is statistical difference between the two groups. Conclusions Soft tissue diffusion-weighted imaging in combination with conventional sequences can help to identify soft tissue tumors and soft tissue abscesses.
