Role of Diffusion Weighted MRI in Intra-Axial Brain Tumours

role of diffusion-weighted mri (dwi-mri) in the diagnosis of brain complications caused by heroin substance abuse

background : magnetic resonance imaging (mri) offers higher diagnostic accuracy for brain lesions caused by heroin abuse compared to compute tomography (ct) scan. these lesions have a low signal on t1-weighted (t1w) images and a high signal on t2-weighted (t2w) and fluid-attenuated inversion recovery (flair) images. this study aimed to evaluate the role of diffusion-weighted mri (dwi-mri) in he...

Diffusion MRI for Characterising Childhood Brain Tumours

Evaluating of Parotid Gland Tumours According to Diffusion Weighted MRI

The aim of this study is evaluating the contribution of diffusion-weighted MR imaging (DWI) in the final diagnosis of patient that parotid gland tumours has been determined. Fourty patients with 41 parotid masses were included to this study. The mean Apparent Diffusion Coefficient (ADC) values were calculated for all of lesions by performing DWI. 28 benign and 13 malignant tumours were detected...

Diffusion-weighted MRI moves beyond brain

MR imaging can be used for many applications in oncology. Its main roles in cancer imaging are determining locoregional tumor extent, characterizing tumors, and monitoring treatment. MRI, like CT, relies on morphological criteria for lesion differentiation. This reliance, however, can make it difficult to detect small cancerous deposits and to differentiate tumor recurrence from treatment-induc...

Analysis of an Axial T2 Weighted Brain MRI

This paper simply encapsulate the recent developments in the field of Symmetry based approaches to detect tumor and then came up with a new parameter which plays a crucial role in proving that a high degree of Symmetry is present in an axial normal human brain MRI (Magnetic resonance Imaging) and this symmetry get affected or not present in anomalous cases highlighting the fact that tumor might...
