所有病例均由2名有5年乳腺MRI诊断经验的主治医师采用双盲法分别在T1 mapping伪彩图测量T1弛豫时间,取病灶最佳层面测量,绘制感兴趣区面积为0.5~1.0 cm2,尽量保证增强前T1(T1pre)、增强后T1(T1post)和表观扩散系数(ADC)测量感兴趣区在...

MRI是基于人体内氢质子(1H)含量的成像方法,不同组织内自由水1H及脂肪1H含量均不相同,T1值亦不同,通过测量组织T1值鉴别不同类型病变正是基于这一原理。本研究选取3种肝脏局灶性病变:肝血管瘤、肝细胞癌及肝转移瘤,结果发现3组病变初...
T1, T2 and PD values were simultaneously measured in each of the 28 regions of interest and were compared among different groups with One-way ANOVA. Values of group RES were set as reference values and linear regression was performed for values of group EME and NOR versus the reference ...
However, to the best of our knowledge, there have been no studies which were focused on comparing the diagnostic performance of T1ρ and T2 mapping for the assessment of OA patients. The purpose of the present study is to compare the usefulness of T1ρ versus T2 mappings for detecting and ...
回顾性分析成都市第五人民医院2021年2—8月因乳腺病变行常规MRI及扩散加权成像者80例(良性35例,恶性45例),并用多翻转角成像序列分别于增强前及增强7 min后采集T1 mapping图像,测量病灶的增强前T1弛豫时间(T1pre)、增强后T1弛豫时间(T1post)、表观扩散系数(ADC)及正常腺体T1pre。比较增强前病灶与正常腺体T1值的...
Magnetic resonance imaging (MRI) T2 and T1ρ relaxation are increasingly being proposed as imaging biomarkers potentially capable of detecting biochemical changes in articular cartilage before structural changes are evident. We aimed to: 1) summarize MRI methods of published studies investigating T2 and ...
OBJECTIVE :The aim of this study was to investigate the rate of incidence, transformation, and reverse transformation of Modic changes (MCs) using T1-weighted (T1W) and T2-weighted (T2W) lumbar magnetic resonance images (MRI) over ... H Tamai,M Teraguchi,H Hashizume,... - 《Spine》 被...
V1 Versus V2 Versus V7 Comparison The signal difference between V1 and V2 measured at the middle (X = 50; Fig. 5e/f) of the BAM profiles per subject and per hemisphere is significant for both 7 T data (t(df = 8.4) = 10.1; p < 0.00001) and 3 T data (t(df...
