骨挫伤

MRI还发现关节镜无法观察到的骨挫伤、隐匿性骨折等改变。

MRI also found bone bruise and occult fracture that were missed by arthroscopy .

MRI检查25例显示隐性骨折呈现长T1、短T2或不规则状线形异常信号，其周围可见不规则长T2骨挫伤水肿异常高信号影，均伴有周围软组织水肿的异常信号。

Twenty five cases with occult fractures using MR imaging showed long T 1 and short T 2 linear and irregular abnormal signal . Irregular long T 2 abnormal high signs of bone bruise and circumference soft tissues edema were seen around the region of occult fractures .

结论：MRI是早期诊断和定期随访膝关节骨挫伤的重要影像学方法。

Conclusion : MRI is an important imaging method for early diagnosis and follow-up study of knee joint contusion .

方法回顾分析40例膝关节外伤的MRI图像，观察骨挫伤的MRI表现和合并的其他损伤。

Methods MR images of injuries of knee in40 cases were retrospectively analyzed , the complications were reviewed simultaneously .

目的评价反转回波脂肪饱和序列（STIR）成像在膝关节骨挫伤中的临床应用价值。

Objective To evaluate the application of STIR in knee joint bone contusion .

骨挫伤是骨小梁显微骨折，早期诊断可使病人得到早期和正确治疗，MRI检查是重要的诊断方法。

Bone contusion is local trabecular microfractures , early diagnosis can allow patients early treatment , the important diagnostic tool is MRI .

方法选择32例膝关节骨挫伤的病例，通过随访1、3、6个月及12个月后观察MRI信号的改变。

Methods MRI appearances of bone contusions of the knee joint in 32 cases were observed in 1,3,6 and 12 months respectively by MRI .

方法回顾性分析43例胫骨平台骨挫伤的MRI影象学表现，评估其诊断作用和临床意义。

Methods The MRI data of 43 cases with tibia plateau contusions were analyzed retrospectively . The value on diagnosis and its clinical significances were evaluated .

方法100例骨挫伤均行X线平片、SET1WI、SET2WI和FET2WI序列检查，35例另行CT检查。

Methods : 100 cases with bone contusion were performed SE T_1WI 、 FSE T_2WI 、 FE T_2WI sequence and X-ray plain film , and 35 cases of them were performed additionally CT .

结论FET2WI序列对骨挫伤的诊断具有高度的敏感性，突出了骨髓水肿的显示，成为骨挫伤MRI影像诊断中首选的成像技术。

Conclusion : FE-T_2WI sequence is sensitive in the diagnosis of bone contusion , and should be the first choice diagnostic technique , especially in demonstration of bone marrow edema .

MRI表现分别为骨挫伤伴或不伴骨折、关节腔积液、半月板损伤、韧带损伤、关节周围软组织损伤。

Knee joint injury manifested as bone contusion or bone contusion accompanied with bone fracture , joint effusion , meniscus injury , ligament injury , para-articular soft tissue injuries with MRI .

2）检出骨挫伤敏感的MRI序列为STIR及T1W（I100%及95.7%）；

STIR , T1WI were more sensitive lesion detection series in bone contusion ( 100 % and 95.7 % ) .

在SE序列上骨挫伤表现为T1加权不规则低信号和T2加权高信号，STIR显影更为清晰。

With SE sequence , the signal of bone contusion was irregular on T_1 , and high on T_2 , which was more clear on STIR sequence .

胫骨外侧平台后缘和股骨外侧髁的对吻骨挫伤和胫骨髁间前区隐性骨折，提示ACL损伤。
