BPH和PCa是中老年男性常见疾病,早期PCa与BPH症状类似,目前常用的诊断方法包括直肠指检、血清前列腺特异性抗原水平、MRI和经直肠超声引导下穿刺活检,其中MRI不仅在PCa检测、定位、诊断、侵袭性评估等方面有显著优势,还能从水分子扩散、循环灌...

We also found a significant correlation between asymmetric motor features and asymmetry based on T 1ρ . This study provides additional validation of T 1ρ and T 2ρ as a means to separate PD from control subjects, and T 1ρ may be a useful marker of asymmetry in PD. 展开 关键词:...
A new type of dual-mode T1 and T2 magnetic resonance imaging (MRI) contrast agent based on mixed lanthanide oxide nanoparticles was synthesized. Gd3+ (8S7/2) plays an important role in T1 MRI contrast agents because of its large electron spin magnetic moment resulting from its seven unpaired...

MRI was performed using a 3T MRI scanner, and T2 maps were calculated from a sagittal multi-echo acquisition. Two regions of interest (ROIs) were positioned within PTFJ cartilage and medial femoral condyle (MFC) cartilage. The average T2 value and standard deviation (SD) of each ROI were ...
For this purpose, means of T2 quantifications were calculated for the repeated measurements. Out of these average values, the difference and mean of the two segmentation techniques, respectively the two readers, were determined and for all compartments collectively plotted against each other. The ...
MRI T2* (r=0.378, P=0.047). Age was not significantly correlated with SF, LVEF, or liver MRI T2*. Conclusion Magnetic resonance imaging (T2*) detection is an effective and non-invasive means for detecting myocardial and liver iron overload in ...
MRI is an accurate means of characterizing liver lesions.Unenhanced images should comprise in-phase and opposed-phase gradient echo (GRE) T1, and T2 weighted acquisitions.Dynamic gadolinium enhanced imaging characterises most focal liver... P Manoharan,J Ward - 《Imaging》 被引量: 0发表: 2004年...
Insights into the supplying role of different feeding areas are gained. In meningeomas with low perfusion and/or additional pial-cortical supply the PTE effect on the periphery close to the cortex is freqeently missed. 展开 关键词:Meningeomas Embolization Perfusion Diffusion Dynamic MRI ...
