Purpose: To assess the utility of diffusion-weighted imaging (DWI) with apparent diffusion coefficient (ADC) maps and T2* mapping in quantitative analysis of nucleus pulposus (NP) and annulus fibrosus (AF) of lumbar intervertebral discs with its correlation with modified Pfirrmann grading (MPG) ...
The bone structures are rather more difficult to view on a weighted MRI T2 than on a CT-Scan: for more details on the bones of the face, please refer to the e-Anatomy module “Face-CT-Scan”. The teeth were numbered using the FDI World Dental Federation notation ISO-3950. Due to ...
具备典型三联征中的至少一种表现;2. 影像学发现无其他原因引起的脑室扩大,Evans 指数>0.3, 且排除其他引起脑室扩大的病因;脑室周围水肿带(CT 上显示脑室周围低密度影或 MRI 的 T2 加权像上脑室周围显示稍高信号);MRI 冠状位出现 DESH 征;3. 腰穿测压示 ICP≤200 mmH2O,脑脊液常规生化检测结果正常;4. 临床表...
El tap test consiste en la extracción de 40 o 50 ml de LCR mediante una punción lumbar, tiene un valor predictivo positivo muy alto (de hasta el 90%) y, sin embargo, escasa sensibilidad (26-61%). El test de infusión salina, con medida de la resistencia de salida de LCR, ...
摘要: 目的:探讨正常人体腰椎骨高场强MRI信号随年龄、性别变化的规律及类型。方法:随机筛选了470例正常腰椎的MRI影像,男235例,女235例。按10岁一年龄组,共分8组。以T1WI为重点进行回顾性观察,按信号表现归类,对信号类型与年龄性别的关系做统计学处理。结果:依据椎体内...
Y Kong,Y Qiang,B Dong,DO Mri 摘要: Objective To explore the difference of observed value about normal adult knee articular cartilage thickness measured by 3D WATS and T2 mapping original image with 1. 5T MR. Methods 95 normal adult male( age ranged from 20 to 35 years) knee underwent ...
The National Institutes of Health (NIH) (https://www.ninds.nih.gov/) reports that, in patients with suspected NPH, a variety of tests, including brain CT and/or MRI, a spinal tap or lumbar catheter, intracranial pressure monitoring, and neuropsychological tests are helpful to diagnose NPH ...
A quadric ventricular hydrocephalus was identified on MRI. The patient was diagnosed with idiopathic cerebral hydrocephalus and neurosurgery was solicited. After 3 therapeutic depletive lumbar punctures (cerebrospinal fluid tap test), there was a moderate improvement in the psychiatric symptomatology, but ...
Preoperative 3T MR imaging of rectal cancer: local staging accuracy using 2D T2-weighted FSE sequence and diffusion-weighted MRI with b-multiple SE-EPI (SS 601a), B-0402 Boraschi P., Donati F., Urbani L., Gigoni R., Gherarducci G., Pacciardi F., Masi G., Falaschi F., Bartoloz...
The neuroimaging tests performed on all patients were as follows: (1) head MRI (Phillips’ Ingenia 3.0 Tesla), including 3D volume T1-weighted, T2-weighted, fluid-attenuated inversion recovery, and susceptibility-weighted imaging sequences; (2) CBF SPECT, which was done 10 min after intravenous...
