DR与MSCT在儿童副鼻窦疾病诊断中的应用比较

A comparison of DR and MSCT in the diagnosis of paranasal sinus diseases in children

目的比较并分析DR与MSCT在儿童副鼻窦疾病诊断中的临床应用。方法回顾性分析经我院临床确诊的副鼻窦疾病患儿105例,包括临床表现,DR与MSCT影像资料,并复习相关文献,比较两种影像学检查手段对病变检出率;所有患者均行东芝MRAD-D50SDR柯瓦氏位数字摄片及飞利浦Brilliance 6层螺旋CT扫描仪副鼻窦横断位容积扫描。结果 105例患儿中,DR检出副鼻窦炎54例,粘膜下囊肿13例,息肉2例,黏液囊肿1例,骨瘤3例,副鼻窦骨折3例;MSCT检出副鼻窦炎68例,粘膜下囊肿16例,息肉5例,黏液囊肿4例,骨瘤3例,副鼻窦骨折9例。结论 DR对儿童副鼻窦病变提供的诊断信息有限,对蝶窦及鼻腔内情况知之甚少,容易漏诊;MSCT容积扫描数据多平面重建后能全面观察副鼻窦病变,可以精准地定位及定性;在儿童副鼻窦疾病诊断中MSCT具有绝对优势,值得临床推广应用。

Objective To compare and analyze the clinical application of DR and MSCT in the diagnosis of paranasal sinus diseases in children. Methods Clinical manifestation,DR and MSCT images of 105 Children clinically diagnosed as paranasal sinus diseases were analyzed retrospectively. Detection rates of two imaging methods were compared. All patients underwent DR using Toshiba MRAD-D50 SDR and axial volume scanning of paranasal sinus using Phillips Brilliance 6 slice spiral CT scan. Results Among those 105 patients,54 paranasal sinusitis,13 submucous cysts,2 polyps,1 mucocele,3 osteomas,3 maxillary sinus fracture were detected by DR,while,68 paranasal sinusitis,16 submucous cysts,5 polyps,4 mucocele,3 osteomas,9 maxillary sinus fracture were found by MSCT. Conclusion DR provides limited diagnostic information for paranasal sinusitis and has limited information about sphenoid sinus and nasal disease,which is easily misdiagnosed. By multiplanar reconstruction of MSCT volume scan,paranasal sinus diseases can be completelly observed,positioned and characterized. In children＇s paranasal sinus diseases,MSCT has a distinct advantage and deserves popularization.
