(3) There were significant differences in a linear black signal area of STIR image in MRI among the three groups (P < 0.05) (伪'=0.0513=0.017). Significant differences were found as compared the low energy group with non-obvious external force group and h...
At short to medium TI’s, long T1 substances (such as CSF) are bright on magnitude IR. This is opposite to SE where long T1 values cause reduced signal intensity. Additive T1 and T2 effects. MS plaque seen better on STIR image (right) than SE image (left) ...
Abstract:Objective To compare the effects of optimized short TI inversion recovery(STIR)and iterative dixon of water-fat with echo asymmetry and least-squares estimation(IDEAL)fat suppression technique on MRI image quality of metal implants. Methods Thirty patients requiring MRI examination after lumbar ...

在我院就诊的肺结节患者中选取120例,所有患者均行MRI检查以及病理检测。测定 肺结节信号强度评分、ADC值、SNR值。结果 120例肺结节患者中,良性结节41例,恶性结节79例。良性 与恶性肺结节信号强度评分、ADC值、SNR值之间均有显著差异(P<0.05)。结论 STIR-EPI序列可作为肺 ...
STIR-FLAIR序列更利于Graves眼病活动期眼外肌增粗的评价,但对眼眶炎性浸润的显示STIR-FLAIR序列可能稍逊于T2W-SPIR序列;对于眼眶部血管源性病灶两种序列诊断效能类似,而在脉络膜血管瘤检出方面,STIR-FLAIR序列则有一定优势.由此,我们推荐将STIR-FLAIR序列用于临床眼眶MRI检查,尤其在临床怀疑有眼球或视神经病变时,可以...
Eight cases where MRI scanning was performed were identified. Before application of the spica cast, we used radiographic screening to assess the stability of the reduction. Absence of the ossific nucleus within the femoral head made confirmation of the location with the image intensifier unreliable....
which was reported before to have significant beneficial effects on image quality21,22,33,38. Further limitations are that MRI analysis was conducted on carious lesions detected on dental x-ray, the detection accuracy of MRI for dental caries has not yet assessed. The scanning time of the appli...
