Object: Vertebrobasilar dissecting aneurysms (VBDAs) are known to have a poor natural history with high rates of re-bleeding and mortality. There is a strong relation between hyperhomocysteinemia (HHcy) and cerebrovascular disease; we perform a retrospective study within the male of Chinese Han population to explore the association between HHcy and VBDAs.
Methods: Eighty-eight male patients with VBDA and Eighty-one male control subjects were evaluated for their serum total homocysteine levels.
Objective: Proton magnetic resonance spectroscopy (H-MRS) can benefit the differentiation of gliomas preoperative grading and facilitate guiding biopsy. This study was to investigate the optimal metabolite or metabolic ratios of MRS for the biopsy target delineating by using the technique of MRS imaging guided frame-less stereotactic biopsy.
Methods: During a 4 year period between the Sep 2012 and Oct 2016, 57 patients (25 women, 32 men; mean age, 46.
The arcuate fasciculus is a critical component of the neural substrate of human language function. Surgical resection of glioma adjacent to the arcuate fasciculus likely damages this region. In this study, we evaluated the outcome of surgical resection of glioma adjacent to the arcuate fasciculus under the guidance of magnetic resonance imaging and diffusion tensor imaging, and we aimed to identify the risk factors for postoperative linguistic deficit.

There is a strong relation between hyperhomocysteinemia (HHcy) and cerebrovascular disease; we perform a retrospective study within the Chinese Han population to explore the association between HHcy and IAs. Two hundred six patients with IAs and 206 control subjects were evaluated for their serum total homocysteine levels.

The records of 60 patients (30 women, 30 men; mean age, 45.4 years) suspected of having gliomas who underwent an ADC image-guided stereotactic biopsy were retrospectively reviewed.

To achieve this aim, we implemented functional neuro-navigation and intraoperative magnetic resonance imaging (iMRI) into the biopsy procedure. The impact of this integrated technique on the surgical outcome and postoperative neurological function was investigated and evaluated.

Aim: We investigated whether prostate fibrosis was associated with urinary dysfunction in chronic prostatitis (CP) and whether resveratrol improved urinary dysfunction and the underlying molecular mechanism.
Methods: Rat model of CP was established via subcutaneous injections of DPT vaccine and subsequently treated with resveratrol. Bladder pressure and volume tests investigated the effect of resveratrol on urinary dysfunction in CP rats.
This study is to measure the diagnostic examination quality of magnetic resonance spectroscopy in differentiating high-grade gliomas from metastases. PubMed, Embase, and Chinese Biomedical databases were systematically searched for relevant studies published through 10 July 2016. Based on the data from eligible studies, heterogeneity and threshold effect tests were performed; pooled sensitivity, specificity, and areas under summary receiver-operating characteristic curve of magnetic resonance spectroscopy were calculated.
View Article and Find Full Text PDFOBJECTIVE Endoscopic removal of intracerebral hematomas is becoming increasingly common, but there is no standard technique. The authors explored the use of a simple image-guided endoscopic method for removal of spontaneous supratentorial hematomas. METHODS Virtual reality technology based on a hospital picture archiving and communications systems (PACS) was used in 3D hematoma visualization and surgical planning.
View Article and Find Full Text PDFObjective: Magnetic resonance spectroscopy (MRS) is a powerful tool for preoperative grading of gliomas. We performed a meta-analysis to evaluate the diagnostic performance of MRS in differentiating high-grade gliomas (HGGs) from low-grade gliomas (LGGs).
Methods: PubMed and Embase databases were systematically searched for relevant studies of glioma grading assessed by MRS through 27 March 2015.
Objective: To evaluate the efficacy of intraoperative magnetic resonance imaging (iMRI) and multimodal navigation in surgical resection of glioblastoma.
Methods: Between February 2009 and July 2010, 76 glioblastoma patients underwent surgical resection guided by iMRI and multimodal navigation. The cohort consisted of 43 male and 33 female patients, with a mean age of 49 years (range: 14-79 years).
Objectives: To evaluate the efficacy of integration of metabolism images into multimodal neuronavigation for frameless stereotactic biopsy.
Methods: From January to December 2012, 32 patients with brain lesions underwent frameless stereotactic biopsy guided by positron emission tomograph (PET) and proton magnetic resonance spectroscopy ((1)H-MRS)-based multimodal neuronavigation and intraoperative magnetic resonance imaging (iMRI). The cohort consisted of 16 male and 16 female patients, with a mean age of 45 years (range: 7 - 62 years).
Objective: To evaluate the influences of high-field intraoperative magnetic resonance imaging (iMRI) on the extent of resection (EoR) in low-grade gliomas.
Methods: Fifty-nine patients with low-grade gliomas underwent microsurgeries under the guidance of high-field iMRI and functional neuro-navigation. The rates of gross total removal and EoR were recorded after initial and final iMRI scans and neurological performances were evaluated peri-operatively and at follow-up.
Objective: To evaluate the clinical value of VarioGuide in stereotactic brain biopsy.
Methods: Fifteen patients with brain lesions underwent frameless stereotactic brain biopsy guided by VarioGuide and multimodal neuronavigation. Intraoperative magnetic resonance imaging (iMRI) was used to confirm the accuracy of biopsy.
Objectives: To review the preliminary clinical experience with high-field-strength intraoperative magnetic resonance imaging (iMRI) suite with neuronavigation system in the pituitary adenoma operation with transsphenoidal approach.
Methods: From March 2009 to December 2010, 31 patients [range, 29 - 76 years, mean age (47 ± 11) years]of pituitary adenoma were operated with transsphenoidal approach and intraoperatively with a movable 1.5 T high-field-strength iMRI suite in combination with neuronavigation system.
