Magnetic resonance spectroscopy on hepatocellular carcinoma after transcatheter arterial chemoembolization.

Background And Objective: Proton magnetic resonance spectroscopy (MRS) of the liver in vivo is in experimental phase. MRS observation on liver cancer after transcatheter arterial chemoembolization (TACE) has seldom been reported. This study was to investigate the value of MRS in assessing the metabolic changes of hepatocellular carcinoma (HCC) after TACE.

[Motor cortex by real-time imaging process functional MRI during finger movements].

Objective: To explore the techniques of RTIP-fMRI scanning and the correspondence between structure and functional changes of motor cortex during self-paced finger movements by RTIP-fMRI in normal volunteers.

Methods: The 15 healthy volunteers were studied by RTIP-fMRI, and the activation tasks consisted of self-paced finger movements performed with the right and the left hands. Image postprocessing was done on the workstation by "correlation coefficient" algorithm analysis method, IAC and SPM software.
