T1 and T2 in the Brain of Healthy Subjects, Patients with Parkinson Disease, and Patients with Multiple System Atrophy: Relation to Iron Content1 PURPOSE: To investigate the potential of magnetic resonance imaging for identification and quantification of brain iron in healthy subjects, patients with ...
POSTHERPETIC NEURALGIA PATIENTS SHOW ABNORMAL LOCAL BRAIN ACTIVITY BEYOND PAIN MATRIX: A RESTING-STATE FUNCTIONAL MRI STUDY BACKGROUND: Herpes zoster (HZ) can develop into postherpetic neuralgia (PHN), both of which are painful diseases. PHN patients suffer chronic pain and emot... S Cao,Y Zhang...
2. Result: the accuracy of localizing diagnosis was 100%, five neurogenic tumor showed longer t1 and longer t2 signals with abnormal contrast enhancement. three meningiomas showed iso-or longer t1 and iso-or longer t2 with signal of meningiomas can be inhomogeneous because it has calcification. ...
It can automatically classify abnormal tissues in human brain in a three dimension space from multispectral magnetic resonance images such as T1-weighted, T2-weighted and proton density feature images. It consists of four steps: data matching, information modelling, information fusion and fuzzy ...
Experimental results and performance of the methods confirm the efficacy of the proposed technique in an automatic segmentation of abnormal tissues in multimodal (T1, T2, Flair, and T1contrast) brain MRIs.doi:10.1007/978-1-4939-3995-4_21Syed M. S. Reza...
Interestingly, to aim at building a biomarker for ASD, we started with a categorical approach by which a supervised machine-learning algorithm was utilized and a diagnostic label was adopted as its teaching signal. However, the results of applying the classifier built for that original purpose to...
Finally, the inferior-temporal cortex is a challenging area in which to obtain strong fMRI signal, especially in the anterior lateral and anterior mesial regions, where susceptibility problems are prevalent, but even in posterior areas, as evidenced by the fairly large SEMs for our ROIs (Figure ...
We also completed a post hoc analysis of potential interactions between blood oxygen level–dependent signal and [18F]fluorodopa uptake by extracting the β values and testing them in a regression model in SPSS (SPSS Inc, Chicago, Illinois) (P < .05). The Cook distance test was used to ...
Contrary to predictions about a valence-specific effect of negative stimuli, we found no valence by group by drug interactions, neither in the dmPFC nor other regions throughout the brain. All of the significant effects were driven by the more robust signal given by contrasts of pictures with ...
