preoperative grading of astrocytic supratentorial brain tumors with diffusion-weighted magnetic resonance imaging and apparent diffusion coefficient
background diffusion-weighted imaging (dwi) is a form of magnetic resonance imaging (mri) based on measuring the random brownian motion of water molecules within the biological tissues and is particularly useful in tumor characterization. objectives the purpose of this study was to evaluate the diagnostic value of dw mri and the apparent diffusion coefficient (adc) for preoperative grading of a...
متن کاملCoronal Diffusion-weighted Magnetic Resonance Imaging of the Kidney: Agreement with Axial Diffusion-weighted Magnetic Imaging in Terms of Apparent Diffusion Coefficient Values
BACKGROUND Coronal diffusion-weighted magnetic resonance imaging (DW-MRI) and apparent diffusion coefficient (ADC) values have gradually become applied (following conventional axial DW-MRI) in the renal analysis. To explore whether data obtained using coronal DW-MRI are comparable with those derived using axial DW-MRI, this preliminary study sought to assess the agreement in renal ADC values be...
متن کاملEfficacy of diffusion-weighted magnetic resonance imaging in the evaluation of extrahepatic cholestasis-related hepatic fibrosis.
BACKGROUND/AIM To investigate the efficacy of diffusion-weighted magnetic resonance imaging (DWI) in the diagnosis and staging of fibrosis induced by experimental bile duct ligation (BDL). MATERIALS AND METHODS Twenty-four rats were divided randomly into four groups: control, BDL--3 days, BDL--2 weeks, and BDL--4 weeks. DWI was performed with b-values of 100 and 500 on the rats from control g...

متن کاملApparent diffusion coefficient by diffusion-weighted magnetic resonance imaging as a sole biomarker for staging and prognosis of gastric cancer
OBJECTIVE To investigate the role of apparent diffusion coefficient (ADC) from diffusion-weighted magnetic resonance imaging (DW-MRI) when applied to the 7th TNM classification in the staging and prognosis of gastric cancer (GC). METHODS Between October 2009 and May 2014, a total of 89 patients with non-metastatic, biopsy proven GC underwent 1.5T DW-MRI, and then treated with radical surgery....
