概括
恶性环形乳腺质量很罕见. 在MRI上的质量形状和增强模式,特别是没有冲洗的圆形和持久的动力学,可以帮助识别良性病例.
科学领域:
- 放射学 放射学是一门学科.
- 在瘤学瘤学.
- 乳房成像 乳房成像
背景情况:
- 在核磁共振 (MRI) 上,限制性乳腺质量的管理在很大程度上依赖于来自其他成像方法的数据.
- 这些病变的MRI特异性数据有限,需要进一步研究.
研究的目的:
- 为了评估恶性局限性乳腺质量的临床和MRI成像特征.
- 在MRI上识别可帮助区分良性与恶性包围乳房质量的成像特征.
主要方法:
- 在2008年至2020年期间,对具有有限质量的乳腺MRI进行了回顾性审查.
- 对临床和成像特征的分析,包括质量形状和动态对比动力学.
- 使用费舍尔的精确测试和威尔科克森的等级总和测试进行统计评估.
主要成果:
- 5.5%的围绕性质量是恶性的.
- 圆形质量 (18.9%) 比圆形质量 (1.7%) 更频繁恶性.
- 恶性瘤的发病率因动态模式而异:持久性 (0%),平原性 (8.7%) 和洗性 (16.7%). 没有冲洗动力学的圆质量显示0%的恶性瘤.
结论:
- 质量形状和动态对比增强动力学对于在MRI上管理有限的乳腺质量是有价值的.
- 没有冲洗动力学的圆形质量和具有持久动力学的有限质量在这个队列中没有显示出恶性瘤.

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...

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...

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
