概括

基于深度学习的重建 (DLR) 显著增强T1加权的3D快速旋转回声 (CUBE) MRI用于可视化垂体腺瘤. 与标准方法相比,这种先进的技术可以改善瘤和周围区域的描绘.

科学领域:

放射学放射学是一门学科.
医疗成像医学成像
人工智能在医学中的应用

背景情况:

垂体腺瘤需要准确的成像来诊断和治疗计划.
增强对比度的MRI对于评估垂体和状腺病变至关重要.
基于深度学习的重建 (DLR) 提供了提高MRI图像质量的潜力.

研究的目的:

评估T1加权的3D快速旋转回声 (CUBE) 序列与DLR用于垂体腺瘤和状区域描绘的诊断性能.
将CUBE与DLR与传统MRI序列进行比较.

主要方法:

24名患有垂体腺瘤或残留瘤的患者接受了对比度增强的MRI.
收购包括带有和没有DLR的CUBE,带有DLR的1毫米2DT1WI和3DSPGR.
神经放射学家对腺瘤和状区域的描绘进行了评分;对比度与噪声比率 (CNR) 计算.

主要成果:

与没有DLR的CUBE相比,使用DLR的CUBE显示出较高的垂体腺瘤描绘分数,使用DLR的1-mm 2D T1WI和SPGR (p<0.01).
腺瘤和洞穴性鼻之间的边界划分在CUBE与DLR相比更好,而1-mm2DT1WI与DLR (p=0.01).
与DLR一起的CUBE显示了改善的观察者间一致性和显著更高的腺瘤的CNR.

结论:

CUBE与DLR显著增强了对比度增强的MRI上垂体腺瘤和状区域的描绘.
这种技术比传统的测序提供了更好的诊断价值,比如没有DLR的CUBE,有DLR的1毫米2DT1WI和SPGR.

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...
