查询词典 abscess

MRI is more sensitive than CT to distinguish the cerebritis stage from the capsule stage. Conclusion: MRI features of brain abscess were well corelated to the clinical stages and pathological changes. MRI is powerful in the determination of clinical stages of brain abscess.

脑脓肿的MRI特征与其临床分期及病理学变化的相关性较好，能更加准确、简便、迅速地区别脓肿的脑炎期和包膜形成期，可作为临床诊治脑脓肿的有力参考。

CONCLUSION摘要: DWI and ADC value are helpful to differentiate capsule formation stage of abscess from cystic/necrotic tumor, but not helpful to distinguish evolution stage/cerebritis stage of abscess from cystic/necrotic tumor.

结论摘要：DWI及ADC值有助于鉴别包膜期脑脓肿和坏死囊变脑转移瘤，对吸收期脑脓肿和坏死囊变脑转移瘤的鉴别诊断无明显意义。

METHODS摘要: Fourteen patients proved pathologically as brain abscess and 17 cystic/necrotic metastatic tumor underwent conventional MRI and DWI examinations. DWI signal and ADC value were evaluated in cerebritis stage, capsule formation stage, and evolution stage of brain abscess and compared with those of cystic/necrotic metastatic tumor. Chisquared test and t test were performed for statistic analysis.

方法摘要：病理及临床证实脑脓肿14例，坏死囊变脑转移瘤17例，经常规磁共振检查及弥散加权检查，在脑脓肿脑炎期、包膜期及吸收期进行弥散信号及ADC值的测量，并和坏死囊变脑转移瘤相比较，统计学分析采用χ2检验和t检验。

In the operation, the place of the external mouth of abscess was designed, the skin was cut along inter muscular septum between the sphincter internus and the sphincter externus, the subcntaneous tissues were separated along the lateral clearance of the sphincter internus to the pelvirectal fossa, then the internal mouth of abscess was cut. The vomica was leaved to idle after being scraped fully, and the pus was drained perennially with fenestrated tube.

采用设计外口的位置，沿内、外括约肌间沟入路，切开皮肤，分离皮下组织，顺内括约肌外侧间隙分离至骨盆直肠窝，切除内口，并将脓腔充分搔刮后旷置，腔内放置有孔胶管持续引流，结合术后祛腐消肿止痛期及活血止痛生肌期的药物换药，旨在提高对骨盆直肠窝脓肿的一次根治率和保护肛门功能，减少并发症发生。

Results (1) Osteitis and destruction of end-plate showed long T1 and long T2.(2) Anterior and lateral abscess had long T1 and long T2 presenting even and structure-less signal.(3) The intervertebral discs showed normal or only degeneration at the early stage, and destroyed at later stage.(4) With Gd-DTPA enhancement, fibrotic granulation around abscess and destroyed area was well demonstrated.(5) Abscess in the bone and/or paraspinal abscess, destruction of end-plate were the important evidence for early diagnosis.

结果 (1)椎体骨炎及终板破坏呈长T1长T2信号，(2)椎旁或椎前冷脓肿呈长T1长T2均匀无结构信号，且上下跨越范围较大，(3)早期椎间盘信号正常或只出现退变，晚期则被破坏，(4)Gd-DTPA增强扫描可清楚显示冷脓肿周围纤维肉芽组织及椎管内侵犯，(5)骨内小脓肿和/或椎旁脓肿、椎体终板破坏是MRI诊断早期脊柱结核的重要依据。
