目的:分析阴茎硬结症(Peyronie病)的MRI表现,探讨高场强MRI对阴茎硬结症的诊断价值。方法:14例临床确诊阴茎硬结症于我院行3.0T MRI检查的病例纳入研究,每例2~4次阴茎超声检查。MRI检查采用小表面线圈,检查序列包括常规及磁敏感加权成像(SWI)序列。将MRI结果与超声对照。结果:14例中MRI检查共发现25个硬结,其中3例炎性硬结(共7个)、4例纤维性硬结(共8个)、7例含钙化的混合性硬结(共10个),上述7例钙化结节于SWI均为低信号。超声可稳定检出含钙化的硬结(7例20次超声均检出,20/20),但不能准确判断炎性及纤维化硬结(7例23次超声发现3次,共6处纤维性硬结)。MRI需结合SWI序列才能判定有钙化的硬结;超声对炎性硬结(0/7例)和纤维性硬结(6/8例)的检出率均较MRI低。结论:高场强MRI检查对阴茎硬结症有较高的诊断敏感性及准确性,多序列成像可检出不同性质的硬结,有助于对阴茎硬结症的早期发现,为该病的诊断提供另一个检查选择。
Objective: To analyze the MRI findings of Penile Sclerosis (Peyronie’s disease) and to explore the diagnostic value of high field MRI in the treatment of Penile Sclerosis. Methods: 14 cases of clinically diagnosed penile sclerosis in our hospital 3.0T MRI cases were included in the study, 2 to 4 cases of penile ultrasound. MRI uses a small surface coil and the examination sequence includes both conventional and magnetically susceptible weighted imaging (SWI) sequences. MRI results and ultrasound control. RESULTS: Of the 14 cases, 25 were diagnosed by MRI, including 3 inflammatory sclerosis (7 in total), 4 fibrous sclerosis (8 in total), 7 calcified mixed sclerosis (10 in total) The seven calcified nodules in the SWI are low signal. Ultrasound can stably detect calcified induration (7 cases of 20 ultrasound were detected, 20/20), but can not accurately determine the inflammatory and fibrosis induration (7 cases of 23 times the ultrasound found 3 times, a total of 6 fibrous sclerosis ). MRI should be combined with the SWI sequence to determine the presence of calcified induration. The detection rate of ultrasound on inflammatory sclerosis (0/7 cases) and fibrous sclerosis (6/8 cases) is lower than that of MRI. CONCLUSION: High-field MRI has high diagnostic sensitivity and accuracy for penile sclerosis. Multi-sequence imaging can detect different types of induration and contribute to the early detection of penile sclerosis. It provides the diagnosis of the disease Another check option.
