The spectrum of female urethral and periurethral disorders includes both benign and malignant entities. Establishing an accurate clinical diagnosis may be challenging because symptoms and physical findings frequently overlap among the various entities. Recent technologic advances in magnetic resonance (MR) imaging and ultrasonography (US) allow more detailed evaluation of urethral and periurethral abnormalities. Advances in MR imaging hardware and pulse sequences allow high-resolution, high-contrast static and dynamic imaging of the female urethral and periurethral region in the context of the entire pelvic floor. Similarly, the introduction of high-resolution surface and intracavitary transducers in conjunction with three-dimensional acquisition have enhanced the role of US in this clinical setting. High-resolution MR imaging and real-time US have exciting potential as tools for more comprehensive analysis of the pathophysiologic features of the complex disorders that affect the female urethra and periurethral tissues.
女性尿道和尿道周围疾病的范围包括良性和恶性病变。由于各种病变的症状和体格检查结果经常重叠，因此准确的临床诊断可能具有挑战性。磁共振成像（MR）和超声检查（US）的最新技术进步可以更详细地评估尿道和尿道周围的异常。MR 成像硬件和脉冲序列的进步允许在整个盆底的背景下对女性尿道和尿道周围区域进行高分辨率、高对比度的静态和动态成像。同样，高分辨率表面和腔内换能器与三维采集的结合，增强了 US 在这种临床环境中的作用。高分辨率 MR 成像和实时 US 具有令人兴奋的潜力，可以更全面地分析影响女性尿道和尿道周围组织的复杂疾病的病理生理特征。
