概括

这项研究表明,3D超声波软件可靠地测量了尿路扩张的儿童的体积和水. 半自动化细分工具在不同评级者之间提供一致的结果.

科学领域:

儿科放射学儿科放射学
医学成像分析医学成像分析
泌尿器科泌尿器科泌尿器科泌尿器科

背景情况:

儿童尿道扩张 (UTD) 需要精确的体积评估来管理.
传统的2D超声波方法在精确的体积定量方面存在局限性.
三维 (3D) 超声波为改善脏结构体积分析提供了潜力.

研究的目的:

为了评估半自动3D超声波 (US) 分段软件的可靠性.
评估其在测量体积水缩指数 (HI) 和儿科UTD中膜/骨盆体积的准确性.
为了确定3D US细分软件的评级者间可靠性.

主要方法:

有UTD的儿童接受美国脏检查的未来招生.
获取二维和三维超声数据集.
通过3个独立的评分员使用3D美国数据,对膜和收集系统进行半自动细分.
在体积测量中使用类内相关系数 (ICC) 分析评价者之间的可靠性.

主要成果:

分析了47名儿科患者的48项研究.
对于大多数参数,评级者之间的可靠性几乎是完美的 (ICC 0.85-0.95).
体积测量HI显示在严重的UTD (P2:0.75,P3:0.66) 中较低的分级间一致性.

结论:

半自动的3D US细分是评估儿科UTD中脏尺寸和体积的可靠工具.
该软件提供了对膜的一致测量和在评级者之间收集系统体积.
虽然通常可靠,但在严重的UTD中体积HI评估可能需要进一步细化或仔细解释.

Imaging Studies II: Ultrasonography

IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...

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...

Urodynamic Studies: Uroflowmetry

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...
