概括

前列腺动脉栓塞 (PAE) 可以导致PI-RADS ≥3病变在MRI上的稳定性或降级. 需要进一步的研究来证实PI-RADS在PAE后得分的诊断可靠性.

科学领域:

放射学放射学是指放射学
干预性放射学干预性放射学
泌尿器科泌尿器科泌尿器科泌尿器科

背景情况:

前列腺动脉栓塞 (PAE) 是一种治疗下尿路症状的方法.
使用PI-RADS评分的前列腺磁共振成像 (MRI) 用于评估可疑病变.
在PAE后PI-RADS分数的变化需要评估.

研究的目的:

在PAE后的前列腺MRI上评估PI-RADS≥3病变的演变.
为了确定PAE是否影响PI-RADS预先存在的病变的分类.

主要方法:

对经过PAE的18名患者进行了回顾性分析.
纳入标准:PAE前MRI,至少有一个PI-RADS ≥3损伤.
评估PI-RADS得分变化,心脏病发作和前列腺体积在随访MRI上的评估.

主要成果:

在PAE后没有出现新的PI-RADS ≥3病变;没有病变升级.
在PI-RADS 5中,病变被降级为PI-RADS 1.
PI-RADS 4和PI-RADS 3病变显示稳定或降级,其中一些达到PI-RADS 1状态.

结论:

前列腺MRI上的PI-RADS≥3病变在PAE后往往会稳定或降级.
放射病理相关性是必要的,以验证PI-RADS评分可靠性PAE后.
PAE并不意味着治疗潜在的前列腺癌.

Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

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,...
