概括
T2*映射有效地识别了阴道分娩后的部肌肉 (LAM) 损伤. 肌肉损伤,而不是 puborectalis,与女性的骨盆底功能障碍有关.
科学领域:
- 盆地图像成像 盆地图像成像
- 肌肉骨的MRI是指肌肉骨的MRI.
- 女人的健康成像成像.
背景情况:
- 盆地肌肉损伤是阴道分娩后的常见并发症.
- 部肌肉 (LAM) 的软弱会导致骨盆底功能障碍.
- 定量MRI技术可以改善对LAM损伤的评估.
研究的目的:
- 通过使用T2参数映射来评估阴道分娩后患有升高肌肉 (LAM) 软弱的患者的盆地肌肉损伤.
- 为了比较T2和T2*在女性 puborectalis和 iliococcygeus肌肉的价值与没有LAM弱点的女性.
主要方法:
- 40名患有LAM衰弱的分娩者和25名对照人接受了T2和T2*映射的盆腔MRI.
- 评估了 puborectalis 和 iliococcygeus 的肌肉.
- 使用统计分析将T2和T2*值进行组对组比较.
主要成果:
- 与对照组 (P=.002和P=.008) 相比,观察到患者组的 iliococcygeus 肌肉中较低的 T2* 值.
- 在两组之间,没有发现T2值对 iliococcygeus 肌肉有显著差异.
- 在患者和对照组之间,对于 puborectalis 肌肉,没有观察到 T2 或 T2* 值的显著差异.
结论:
- T2*映射是一种有效的定量工具,用于评估阴道分娩后的LAM损伤.
- 阴道分娩的损伤更容易发生在 iliococcygeus 肌肉上,而不是 puborectalis.
- 盆地功能障碍可能主要是由于 iliococcygeus 肌肉损伤造成的.

Muscles of the Pelvic Floor and Perineum
1.3K
The muscles of the pelvic floor and perineum are crucial for supporting the pelvic organs, controlling continence, and aiding in sexual function, childbirth, and core stability. They are typically divided into the superficial perineal layer and the deep pelvic floor layer.
Perineal Layer
The perineum is a diamond-shaped area below the pelvic diaphragm, divided into an anterior urogenital triangle that contains the external genitals and a posterior anal triangle housing the anus. The urogenital...

Assessment of the Rectum and Anus
241
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

Imaging Studies VI: Voiding Cystourethrography and Cystography
10
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...

Urodynamic Studies: Uroflowmetry
52
Uroflowmetry is a non-invasive urodynamic test designed to measure various aspects of urination, including volume, flow rate, and the time to void. This test is crucial for diagnosing and assessing conditions such as bladder outlet obstruction, bladder dysfunction, incomplete bladder emptying, incontinence, and urinary tract blockages caused by benign prostatic hyperplasia (BPH) and urethral strictures.Pre-Test Instructions:Before a uroflowmetry test, patients are typically advised to drink...

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy
92
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...
