概括

表面扩散系数 (ADC) 值有效区分使用MRI的良性和恶性部瘤. 较低的ADC值表明恶性瘤,有助于部瘤的诊断和治疗计划.

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:

在医学成像中,区分良性和恶性部瘤是一个重要的诊断挑战.
磁共振成像 (MRI) 是评估部损伤的一个关键模式.

研究的目的:

调查表面扩散系数 (ADC) 值在区分良性和恶性部瘤病变中的有用性.
为了提高诊断准确度,建立ADC截止值.

主要方法:

传统的MRI序列和扩散权重成像 (DWI) 在53名部病理患者身上进行.
使用曼-惠特尼测试,对良性,恶性和炎症性病变组的平均ADC值进行了比较.

主要成果:

与良性病变 (1.43 ± 0.57) 相比,恶性病变的平均ADC值显著较低 (0.86 ± 0.28).
截止值为1.1mm2/s,在区分良性和恶性病变方面表现出高灵敏度 (97.14%) 和准确度 (86.2%).
与状细胞癌 (SCC) (0.93 ± 0.15) 相比,在非霍奇金淋巴瘤 (NHL) (0.59 ± 0.09) 中观察到明显较低的ADC值.

结论:

ADC映射是一种有价值的MRI工具,用于区分良性和炎症性部病变与恶性瘤.
ADC值可以帮助区分不同类型的恶性部瘤,如NHL和SCC.

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...
