概括
在CT骨髓造影 (CTM) 过程中,外周隔膜对比扩散 (ECE) 是常见的,在笔型针头中更频繁地发生. 这一发现通常无症状,不应被误认为是脑脊液泄漏.
科学领域:
- 神经辐射学神经辐射学
- 脊柱成像 - 脊柱成像 - 脊柱成像
- 干预程序 干预程序
背景情况:
- 周周对比扩散 (ECE) 是CT骨髓造影 (CTM) 中已知的发现,但其临床意义尚不清楚.
- 之前的研究表明,笔型针可能对长期刺穿有益,但它们对ECE率的影响尚未得到充分研究.
- 没有先前的研究研究了脊柱针技术因素对ECE率的影响.
研究的目的:
- 为了确定CTM期间ECE的发病率.
- 为了研究脊柱针特征 (类型,尺寸) 与ECE率之间的关联.
- 评估ECE的临床相关性,特别是在对自发脊髓脑脊髓液 (CSF) 泄漏进行评估的患者中.
主要方法:
- 在8年的时间里,对276个CTM案件进行了回顾性审查.
- 两个独立的神经放射学家评估了ECE的存在和程度.
- 基于脊柱针类型,尺寸和穿刺部位水平的ECE率的比较.
主要成果:
- 在28%的CTM病例中观察到ECE.
- 与切割型针相比,笔型脊柱针与ECE的发生率显著更高 (32%对25%).
- 针径和穿孔部位水平没有显著影响ECE率. ECE与外周周周血补丁的需要没有相关性.
结论:
- 在CTM中,ECE是常见的发现,在使用笔类型脊柱针时,发病率略高.
- 无症状的ECE不应该被误解为脊柱CSF泄漏的位置.
- 仅仅在成像上发现ECE并不需要在无症状患者中进行进一步的研究,并且似乎与症状的持续性刺后头痛无关.

Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

1.3K
Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...

Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and...
