MRI Show?What Is More Accurate: MRI or PET Scan?PET Scan vs. MRI: Potential Risks and ChallengesThe Right Scan for the Right Situation You’ve likely heard of PET (positron emission tomography) and MRI (magnetic resonance imaging) scans. But what are the differences between these imaging ...
HS在FLAIR序列表现为海马萎缩及信号增高,然而部分TLE患者的HS在MRI上表现不明显(如图1所示),MRI诊断困难,如果结合PET可以提高检出率;另有10%~20%的患者存在双侧HS,仅采用MRI双侧对比来判断容易漏诊,结合PET可提高定位准确性。此外,部分癫痫患...
FDG-PET and MRI in temporal lobe epilepsy: relationship to febrile seizures, hippocampal sclerosis and outcome. Objective To correlate the volumetric head magnetic resonance imaging (MRI) and fluorodeoxyglucose-positron emission tomography (FDG-PET) scan findings wi... V Salanova,O Markand,R Worth,...
MR scan showed no hippocampal sclerosis, or atrophy. FDG-PET scanning exhibited interictal hypometabolism of the epileptogenic temporal lobe in all three cases. None of the cases had fMRI or intracranial monitoring. There was no history of febrile convulsions or family history of epilepsy. Two ...
FDG-PET improves surgical outcome in negative MRI Taylor-type focal cortical dysplasias Objective:To determine the diagnostic accuracy and prognostic value of FDG-PET in a recent series of patients operated for intractable partial epilepsy associated with histologically proven Taylor-type focal cortical ...
The PET scan is an effective way to help identify cancer, heart disease, and brain disorders, Your doctor can use this information to help diagnose, monitor or treat your condition, PET scans are used in detecting cancer, Revealing whether your cancer ha
在癫痫MDT中,18F-FDG PET帮助放射科医师在9例常规MRI阴性图像中发现微小结构异常;对于癫痫MDT后MRI及VEEG均未得到阳性结果的2例患者,PET图像提示局灶性代谢异常,这帮助神经外科医师明确SEEG颅内电极植入部位甚至手术范围。此外,对于MRI与VEEG阳性结果不一致的7例患者,18F-FDG PET帮助其进一步定位致痫灶和(或)确定了...
In temporal lobe epilepsy (TLE) patients without lesions, major hippocampal sclerosis, or atrophy on magnetic resonance imaging (MRI), the localizing power of [ 11 C]flumazenil (FMZ) and 2-[ 18 F]fluoro-2-deoxy- d -glucose (FDG) was compared using high-resolution positron emission tomography...
All participants were also required to not be taking any illicit drugs (verified by a urine drug test at the day of enrollment and day of scan) and have no MR–PET safety contraindications. Individuals with ASD with epilepsy were excluded if they had a seizure or change in seizure ...
PET/MR双模态影像导航SEEG电极植入可显著提高致痫灶精准定位,并减少患者的创伤和经济压力,进而提高预后疗效,具有良好的临床应用价值。 综上,一体化18F-FDG PET/MR成像可精准定位致痫灶,特别是对MRI阴性的致痫灶的定位定侧具有良好的应用价值,为手术方案制定提供了分子影像学信息,提高了癫痫患者手术治疗的效果。
