All samples were imaged on a 7T/30 MRI scanner (Bruker, Germany) equipped with a quad coil fitted with the 15 ml diameter tube. MRI protocol includes a DTI protocol acquired with a diffusion-weighted spin-echo echo-planar-imaging (EPI) pulse sequence with the following parameters: TR/TE...
METHODS: Based on T1 magnetic resonance imaging (MRI) and on individual sulco-gyral anatomy, we defined a parcellation of the right and the left precentral gyri in 20 healthy subjects (10 right-handers; 10 left-handers). This parcellation gave us the opportunity to study MRI tracks ...

Using the latter function, you can load co-registered anatomical scans or other MRI maps such as T1 and T2 maps and compare them with DTI data within one primary image view window. You can remove an image object out of a primary image view window by clicking the button. But you cannot ...
MRIThe purpose of this study was to evaluate the diagnostic accuracy of preoperative imaging for diagnosis of combined hepatocellular cholangiocarcinoma tumors and to evaluate the clinical and imaging features and demographics of patients presenting to our institution with such tumors.From January 2001 to...
