概括

跨直肠超声波 (TRUS) 和磁共振成像 (MRI) 用于前列腺大小测量. 虽然MRI的准确度略高,但TRUS仍然适用于前列腺癌的治疗.

科学领域:

泌尿器科泌尿器科泌尿器科泌尿器科
医疗成像医学成像
在瘤学瘤学.

背景情况:

精确的前列腺大小测量对于手术规划至关重要,包括前列腺切除术.
跨直肠超声波 (TRUS) 和磁共振成像 (MRI) 是前列腺的主要成像方法.
对于前列腺体积估计的TRUS和MRI的比较准确性需要进一步的临床验证.

研究的目的:

为了比较跨直肠超声波 (TRUS) 和磁共振成像 (MRI) 在估计前列腺体积与前列腺实际体重方面的准确性.
评估前列腺癌患者进行机器人辅助激进前列腺切除术的成像方式差异的临床意义.

主要方法:

对147名前列腺癌患者进行了机器人前列腺切除术的回顾性分析.
术前前列腺大小测量使用跨直肠超声波 (TRUS) 和磁共振成像 (MRI).
前列腺总样品重量获得后机器人前列腺切除术用于比较.

主要成果:

与实际体重相比,TRUS和MRI都显著低估了前列腺体积 (p < 0.001).
核磁共振 (平均差异 -9.5毫升) 比TRUS (平均差异 -14.4毫升) 更准确,两种方式之间有统计学上显著的差异 (p < 0.001).
高度和非高度癌症组之间没有观察到前列腺体重或估计体积的显著差异.

结论:

跨直肠超声波 (TRUS) 和磁共振成像 (MRI) 都低估了前列腺体积.
虽然MRI显示的精度略高,但差异很小,这使得TRUS成为治疗前列腺癌的适当成像工具.
前列腺癌等级似乎不会影响基于成像的体积估计的准确性.

关键词:

Magnetic Resonance Imaging

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Imaging Studies I: CT and MRI

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...
