目的探讨高场封闭式MR导向穿刺活检对诊断腹部不同疾病的临床应用价值。方法搜集高场MR导向穿刺活检的45例患者,其中肝脏8例,胰腺8例,肾脏9例,腹膜后10例,盆腔10例,对其穿刺活检结果与术后组织病理学诊断结果以及临床随访结果进行对照分析,并总结MR导向较其他导向设备活检的优势。结果45例患者在高场MR引导下顺利完成了穿刺,穿刺均一次性成功,手术均在局部麻醉下完成,术中患者耐受性良好,MR引导的穿刺活检均获得了足够的标本,且没有发生明显的并发症。穿刺结果与术后病理比较,总符合率为93.3%(42/45)。结论高场MR无电离辐射,具有较高的软组织分辨率,可任意方位断层成像,多个角度引导穿刺,故对于诊断腹部疾病简单、安全,取材准确可靠,准确率高。
Objective To investigate the clinical value of high field closed MR guided biopsy in the diagnosis of different diseases of the abdomen. Methods Forty-five patients with high-field MR guided biopsy were enrolled. Among them, there were 8 cases of liver, 8 cases of pancreas, 9 cases of kidney, 10 cases of retroperitoneal and 10 cases of pelvic. The results of biopsy and postoperative histopathological diagnosis, The follow-up results were compared and analyzed, and the advantages of biopsy of MR guidance over other guidance devices were summarized. Results All the 45 patients successfully completed the punctures under the guidance of high field MR. All the punctures were successful in one time. The operations were performed under local anesthesia. The patients were well tolerated and all the MR-guided biopsy specimens were obtained. No obvious complications occurred. The results of puncture and postoperative pathology, the total coincidence rate was 93.3% (42/45). Conclusion High field MR has no ionizing radiation, has high soft tissue resolution, can be any azimuthal imaging, multi-angle guiding puncture, it is simple and safe for the diagnosis of abdominal diseases, accurate and reliable drawing, high accuracy.
