MRIThalamusLysosomal storage diseaseBrainIntroduction Lysosomal disorders are rare and are caused by genetically transmitted lysosomal enzyme deficiencies. A decreased T2 signal in the thalamus has occasionally been reported. Aims Because the finding of bilateral abnormal signal intensity of the thalamus on ...
Necrotic Tissue In Pedal Infection: Evaluation by MRI And Its Limitations In The Diagnosis of Abscesses and Osteomyelitis of osteomyelitis by the criteria of (3): focally decreased signal intensity on T1w images, increased signal on T2w images and contrast enhancement. Lastl... H Ledermann,W ...
Further studies using high-resolution neuroimaging techniques such as functional MRI are needed to reveal the neural activation patterns associated with pain empathy in BD. In conclusion, our study provides preliminary but compelling evidence for a pain empathy deficit in BD patients at the ...

For reliable quantification of the GABA signal, we used LCModel software41,42 with a simulated MEGA-PRESS basis set to fit the MRS data and determined n-acetylaspartate (NAA), n-acetylaspartyl-Glx, GABA, Glx, glutamine, and glutathione concentrations using the difference spectra. Each spectrum...

The nature of this hyperintense signal remains elusive and still is matter of discussion. Here we demonstrate hyperintense signalling in T2w MRI and decreased apparent diffusion coefficient (ADC) values following intraventricular injection of 6-OHDA. Moreover, we show decreased GFAP immunoreactivity in ...
The liver in black and white: CT/MRI of increased or decreased attenuation/signal intensity in the liverOBJECTIVE. The purpose of this study was to evaluate whether ferumoxides-enhanced MR imaging of focal hepatic lesions provides distinctive signal intensity and lesion-to-liver contrast changes for...
MRI data acquisition Participants were scanned at the Center for Cognitive Neuroscience Berlin (CCNB), using a 3T Siemens Tim Trio MRI scanner equipped with a 12-channel head coil (Siemens Medical, Erlangen, Germany). For resting-state fMRI images a T2*-weighted echo planar imaging (EPI) seque...
The subject methods may include use of CT and/or PET/CT, or MRI, to measure tumor response at regular intervals. Blood levels of tumor markers, such as CEA (carcinoembryonic antigen), CA19-9, AFP, CA 15.3, or PSA, may also be monitored. Dosages and/or administration schedules may be...
