Abstract

Diagnostic accuracy of magnetic resonance imaging (MRI) interpretation was assessed prospectively in patients with ambiguous genitalia or intersex problems. MRI depiction of the uterus was possible in 93%, the vagina in 95%, the penis in 100%, the testis in 88%, and the ovary in 74% of patients. The strength of MRI lies in the multiplanar capability and tissue characterization by means of T1- and T2-weighted sequences. MRI contributes to accurate morphologic evaluation of müllerian duct structures, the gonads, and the development of the phallus, all of which are essential for appropriate gender assignment and planning of surgical reconstruction.

摘要

对生殖器模糊或两性畸形问题患者进行了前瞻性评估磁共振成像（MRI）解读的诊断准确性。93%的患者子宫可通过MRI显示，95%的患者阴道可显示，100%的患者阴茎可显示，88%的患者睾丸可显示，74%的患者卵巢可显示。MRI的优势在于多平面成像能力以及通过T1加权和T2加权序列进行组织特征分析。MRI有助于对苗勒管结构、性腺和阴茎发育进行准确的形态学评估，所有这些对于恰当的性别认定和手术重建规划都至关重要。
