Normal aging in the central nervous system: quantitative MR diffusion-tensor analysis
Quantitative diffusion tensor analysis correlate with normal aging and may help in assessing normal age-related changes and serve as a standard for comparison with neurodegenerative disorders. Expand

An FA value of about 0.20 was found to be the optimal trackability threshold below which tract elongation is terminated (trackability threshold) in patients with acute or early subacute ischemic stroke causing motor deficits. Expand

The voxel-based morphometry showed a significant gray-matter volume reduction in the left anterior cingulate cortex (ACC) in trauma survivors with PTSD compared with those without PTSD, providing further support for the important role of ACC. Expand
Sarcopenia, intramuscular fat deposition, and visceral adiposity independently predict the outcomes of hepatocellular carcinoma.
Body composition rather than BMI is a major determinant of prognosis in patients with HCC, and sarcopenia, IMF deposition, and visceral adiposity independently predict mortality in patientsWith HCC. Expand
Aging in the CNS: Comparison of gray/white matter volume and diffusion tensor data
Results indicate that diffusion properties and brain volume are complementary markers to the effects of aging. Expand
Detection of common bile duct stones: comparison between endoscopic ultrasonography, magnetic resonance cholangiography, and helical-computed-tomographic cholangiography.
MRCP and HCT-C had similar detectability but the former may be preferable considering the possibility of allergic reaction in the latter, and when MRCP is negative, EUS is recommended to check for small CBD stones. Expand

Further evidence is demonstrated of abnormalities of both the ACC, a structure that is pivotally involved in attention, emotional regulation, and fear conditioning, and of subjacent white matter in the pathology of PTSD. Expand
Selection Criteria for Hepatectomy in Patients with Hepatocellular Carcinoma and Portal Vein Tumor Thrombus
Patients may enjoy long-term survival if they receive hepatectomy with preoperative transcatheter arterial chemoembolization, when the number of primary nodules is no more than two, the portal trunk is not occluded by tumor thrombus, and the indocyanine green retention rate at 15 minutes is better than 20%.

Amyotrophic lateral sclerosis: T2 shortening in motor cortex at MR imaging.
Abnormal iron deposition associated with the degenerative process could be the source of T2 shortening, which is a useful MR imaging finding in the diagnosis of ALS. Expand
Amyotrophic lateral sclerosis: diffusion tensor tractography and voxel‐based analysis
The results suggested that the combination of voxel‐based diffusion tensor analysis and diffusion Tensor tractography might help determine the location of the affected neuronal tissues among ALS patients in a non‐invasive manner. Expand
