概括

与较大的细胞癌 (RCCs) 相比,小脏瘤 (≤3厘米) 在超声波上表现出较少的血液供应和更柔软的纹理. 然而,这些较小的RCC在CEUS上表现出高 perfusion 和延迟对比冲洗.

科学领域:

放射学放射学是一门学科.
在瘤学瘤学.
医疗成像医学成像

背景情况:

细胞癌 (RCC) 是最常见的一种癌.
早期发现和表征小质对于有效的治疗计划至关重要.
多模式超声波提供了一种非侵入性的方法来评估瘤特征.

研究的目的:

根据瘤大小,评估脏细胞癌 (RCC) 的多模式超声波特征.
专门分析小型RCC (直径≤3厘米) 的超声波特征.
为了区分较小和较大的RCC之间的成像发现.

主要方法:

对81个手术切除并通过遗传病理确认的RCC进行了回顾性分析.
进行了多模式超声检查,包括彩色多普勒 (CDFI),微波成像 (MVI) 和对比增强超声 (CEUS).
患者被分为两组:≤3厘米 (n=41) 和>3厘米 (n=40).

主要成果:

与RCCs ≤3cm相比,RCCs>3cm在MVI上显示出显著更高的血管性 (P=0.039) 和更高的中位切割波速度 (SWV) 值 (P=0.038) .
虽然超增强在CEUS动脉期的大型RCC中更频繁,但58.5%的小RCC在60岁后表现出延迟洗 (P=0.005).
与较大的瘤相比,小型RCC在CDFI和MVI上表现出相对较少的血液供应,更柔软的质地,并在CEUS上稍后被洗掉.

结论:

多模式超声波可以区分小型和大型细胞癌.
小RCC (≤3厘米) 呈现出明显的超声波特征,包括降低血管性,软组织和延迟对比洗.
这些发现有助于质的非侵入性表征和管理.

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 I: Kidney, Ureter, and Bladder Studies

Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...

Imaging Studies IV: Magnetic Resonance Imaging

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...
