[Correlation between Fractional Anisotropy and Amyotrophic Lateral Sclerosis, and Effect of Inte- grative Medical Treatment on ALS].

Objective: To explore whether fractional anisotropy (FA) value could be taken as a quantitative indicator for tracing and reexamining amyotrophic lateral sclerosis (ALS), and to analyze the correlation between FA value and integrative medical treatment.

Methods: Totally 18 ALS patients were recruited in this study. All patients received diffusion tensor imaging (DTI) using 3.

Diffusion Weighted Imaging, Diffusion Tensor Imaging, and T2* Mapping of Lumbar Intervertebral Disc in Young Healthy Adults.

Background: Although conventional magnetic resonance imaging (MRI) could provide excellent detection of morphological changes in the diagnosis of lumbar disc degeneration (LDD), it has some difficulties in discriminating minimal changes associated with early LDD before morphological or clinical alterations. Therefore, newer MRI techniques have emerged for investigation of early LDD.

Objectives: The aim of this study was to use diffusion weighted imaging (DWI), diffusion Tensor Imaging (DTI) and T2* mapping to detect lumbar discs in healthy young adults, to evaluate if they could depict the microstructural changes of early LDD.

Role of quantitative intravoxel incoherent motion parameters in the preoperative diagnosis of nodal metastasis in patients with rectal carcinoma.

Purpose: To evaluate the diagnostic value of intravoxel incoherent motion imaging (IVIM) in differentiating metastatic and nonmetastatic lymph nodes in patients with rectal carcinoma.

Materials And Methods: In all, 68 patients with histologically proven rectal carcinoma underwent an IVIM sequence (b = 0, 25, 50, 75, 100, 150, 200, 400, 600, 800, 1000, 1200, 1500, and 2000 s/mm(2) ) on a 3.0T MRI scanner.

Assessment of levator ani morphology and function in asymptomatic nulliparous women via static and dynamic magnetic resonance imaging.

Objective: To evaluate levator ani morphology and function in healthy nulliparous women using static and dynamic magnetic resonance imaging.

Methods: Eighty asymptomatic, healthy nulliparous Chinese women (mean age, 25.3±3.

Dissociated brain organization for two-digit addition and subtraction: an fMRI investigation.

The present study compared the patterns of brain activation elicited by two-digit addition and subtraction problems. Thirty-two Chinese undergraduates of the same educational background and of similar age were asked to assess whether arithmetic operations were true or false during functional magnetic resonance imaging. Results showed that both complex addition and subtraction were supported by the broad neural system that involved regions within the inferior parietal lobule, the precuneus, and the inferior occipital gyrus, as well as some subcortical structures.

[Effects of acupuncture on the cortical functional areas activated by index finger motion in the patient with ischemic stroke].

Objective: To observe the effect of acupuncture on cortical functional areas of the patient with ischemic stroke activated by the index finger motion.

Methods: The cortical magnetic resonance imaging (fMRI) were carried out in 15 cases of ischemic stroke during the index finger motion at acupuncture or non-acupuncture. The distribution of the cortical functional areas activated and the size of the activated region and the intension of signals were measured.

[Comparative study of barium enema, computed tomography and magnetic resonance imaging in preoperative diagnosis of colorectal carcinoma].

Objective: To compare the diagnostic value of barium enema (BE), computed tomography (CT) and magnetic resonance imaging(MRI) in primary colorectal carcinoma.

Methods: A total of 64 patients with suspected colorectal carcinoma received BE (n=39), spiral CT (n=31) and MRI (n=42). The detective results were compared with the surgical results.
