彩色多普勒超声和MRI在甲状旁腺腺瘤定性诊断中的价值及影像特点比较

Comparison of the Value and Image Characteristics Between Color Doppler Ultrasound and MRI in the Qualitative Diagnosis of Parathyroid Adenoma

目的探讨彩色多普勒超声和磁共振成像(MRI)在甲状旁腺腺瘤定性诊断中的价值及影像特点。方法回顾性分析2016年1月至2019年6月我院收治的甲状旁腺腺瘤患者85例。85例患者接受彩色多普勒超声检查,46例患者接受放射性核素甲状旁腺显像,27例患者接受MRI检查。分析各检查下的影像学表现及对甲状旁腺腺瘤的诊断价值。结果超声、核素显像、MRI、超声联合MRI对甲状旁腺腺瘤的阳性检出率分别为83.51%、89.66%、69.23%和95.87%。超声、核素显像、MRI、超声联合MRI对直径小于1cm的甲状旁腺腺瘤的阳性检出率分别为80.77%、73.68%、45.45%和88.46%。超声与核素显像的阳性检出率比较,差异无统计学意义(P>0.05)。超声联合MRI检查的阳性检出率明显高于MRI单独检查(P<0.05)。结论超声可作为甲状旁腺腺瘤的首选诊断方法,联合MRI检查有利于提高检出率,更好的进行术前定位和诊断。

Objective To investigate the value and image characteristics of color Doppler ultrasound and magnetic resonance imaging(MRI)in the qualitative diagnosis of parathyroid adenoma.Methods A total of 85 patients with parathyroid adenoma admitted to the hospital between January 2016 and June 2019 were analyzed retrospectively.Eighty-five patients underwent color Doppler ultrasonography,46 underwent radionuclide parathyroid imaging,and 27 underwent MRI.The imaging findings of each examination and the diagnostic value for parathyroid adenoma were analyzed.Results The positive detection rates of parathyroid adenoma by ultrasound,radionuclide imaging,MRI and ultrasound combined with MRI were 83.51%,89.66%,69.23%and 95.87%,respectively.The positive detection rates of parathyroid adenomas smaller than 1 cm in diameter were 80.77%,73.68%,45.45%and 88.46%,respectively.There was no significant difference in the positive detection rate between ultrasound and radionuclide imaging(P>0.05).The positive detection rate of ultrasound combined with MRI was significantly higher than that of MRI alone(P<0.05).Conclusion Ultrasound can be used as the first choice for the diagnosis of parathyroid adenoma.Combined with MRI,it is beneficial to improve the detection rate and better preoperative localization and diagnosis.
