OBJECTIVE We aimed to do a meta-analysis of the existing literature to assess the accuracy of prostate cancer studies which use magnetic resonance spectroscopy (MRS) as a diagnostic tool. MATERIALS AND METHODS Prospectively, independent, blind studies were selected from the Cochrane library, Pubmed, and other network databases. The criteria for inclusion(More)
BACKGROUNDS AND OBJECTIVES Patients with thyroid dysfunction frequently have neuropsychiatric complaints such as lack of concentration, poor memory, depression, anxiety and mania, which suggest brain dysfunction. However, the underlying process of this dysfunction remains unclear. Recent studies of the glutamatergic system have offered important insight(More)
AIM To evaluate the value of quantitative diffusion tensor imaging (DTI) in assessing the axonal and myelin damage of the optic nerves and optic radiations in patients with chronic primary angle-closure glaucoma (PACG) by using high-field magnetic resonance (MR) imaging (3T). METHODS Twenty patients with bilateral chronic PACG and twenty age- and sex(More)
AIM To investigate the diffusion characteristics of water of optic nerve and optic radiation in healthy adults and its related factors by diffusion tensor imaging (DTI) at 3T. METHODS A total of 107 healthy volunteers performed head conventional MRI and bilateral optic nerve and optic radiation DTI. The primary data of DTI was processed by post-processing(More)
OBJECTIVE To explore the diffusion-tensor imaging (DTI) characteristics of normal-appearing white matter (NAWM) and normal-appearing gray matter (NAGM) on conventional magnetic resonance imaging (MRI) in patients with subcortical ischemic vascular disease (SIVD) and examine the relation of such features with the general cognitive function of the patients.(More)
OBJECTIVE To investigate whether DTI abnormalities in patients with nondemented subcortical ischemic vascular disease (SIVD) are correlated to general cognitive function and executive function independent of conventional MRI parameters. METHODS Sixty-six SIVD patients including 30 with cognitive impairment without dementia (VCIND) and 36 with normal(More)
OBJECTIVE To explore the morphometric abnormalities of brain gray matter (GM) in patients with chronic low back pain (CLBP). METHODS Thirty patients with CLBP and 30 healthy individuals were enrolled and examined with a 3.0 T magnetic resonance (MR) scanner. High-resolution T1 structural MR data were acquired and data analysis was performed using(More)
AIM To investigate wall shear stress (WSS) magnitude and distribution in cirrhotic patients with portal hypertension using computational fluid dynamics. METHODS Idealized portal vein (PV) system models were reconstructed with different angles of the PV-splenic vein (SV) and superior mesenteric vein (SMV)-SV. Patient-specific models were created according(More)
OBJECTIVES Patients with hyperthyroidism frequently have neuropsychiatric complaints such as lack of concentration, poor performance in memory, depression, anxiety and mania. These symptoms suggest the dysfunction of brain. However, the underlying process of this dysfunction is not well understood. At the same time, glutamatergic system has been considered(More)
