主要方法:
- 这是一项前性研究,涉及35名受试者,分为四组:健康对照组,小,中,大 β-thalassemia.
- 使用特定序列的3.0TMRI (3D快速低角度拍摄,T1加权的轮旋回回声) 来评估大腿骨中的质子密度脂肪分数 (PDFF) 和皮质骨厚度 (CBI).
- 统计分析包括ANOVA,相关性和多重回归,考虑临床数据,如年龄,性别,BMI和疾病严重程度.
主要成果:
- 骨髓PDFF在股骨子子区域和疾病严重程度之间有显著差异,显示了受试者群体和股骨子区域之间的显著相互作用.

7.6K
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...

Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...
