概括

磁共振成像 (MRI) 可以识别levator ani (LA) 肌肉参与到perilevator fistulas. 增加囊壁和外部关节的厚度是LA参与的关键指标.

科学领域:

放射学放射学是一门学科.
胃肠病学胃肠病学
手术解剖学手术解剖学

背景情况:

周围囊可能会涉及左侧 (LA) 肌肉,使诊断和治疗复杂化.
准确识别LA参与对于有效的手术规划至关重要.

研究的目的:

为了特征磁共振成像 (MRI) 的特征,带有levator ani (LA) 肌肉参与的周围.
为了确定与LA参与周围囊相关的解剖学和系统因素.

主要方法:

追溯对1697个盆腔MRI扫描的回顾,以确定89名患有周围的患者.
根据靠近上升器肌肉的距离,将囊分类为LA (+) 或LA (-).
对状腺特征,形态测量和临床数据的分析,使用后勤回归来预测LA参与.

主要成果:

79.8%的周游囊都涉及到上游 (LA+).
LA+囊主要是通过沟和密码腺体;LA-囊更经常是通过沟和相关的炎症性肠病.
囊的类型,病因和囊壁和外关节 (EAS) 的增加厚度独立地与LA参与有关 (AUC=0.938).

结论:

在MRI上,透过膜的配置和增加的状壁和EAS厚度与状 (LA) 参与状有关.
这些发现表明,败血症沿外关节空间向上扩展.
准确的MRI映射对于识别隐藏扩展和指导外科管理至关重要.

关键词:

Assessment of the Rectum and Anus

Assessment of the Rectum and Anus

Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.
Rectal Inspection
Begin by inspecting the perianal and anal areas for color, texture, rashes,...

Imaging Studies VI: Voiding Cystourethrography and Cystography

Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...
