P 24: Evaluation of the Voxel Based Morphometry in Quantitative Analysis of Brain MRI Images

Introduction: Voxel based morphometry is a type of statistical parametric mapping that can be used to investigate the effect of diseases such as epilepsy, Alzheimer's disease and Parkinson's disease or other agent such as skills on brain structure (white matter, gray matter and cerebrospinal fluid). The aim of this study is evaluate the effectiveness of this method in detection of differen...

I-45: Advance MRI Sequences in Pelvic Endometriosis

Background: To assess MRI in diagnosing endometriotic lesions, emphasizing T2*weighted imaging efficacy. Materials and Methods: This prospective study of 48 females (22-38 years, average 29.6) clinically suspected of endometriosis from September 2009 to April 2012. MRI was performed with a 1.5 T imager (Siemens) with a body array coil. T1, T2 and T2* weighted (2D-FLASH) sequences were obtained ...

Intensity Correction in Intravascular MRI using Projection Images

Introduction: Potential clinical benefits of high-resolution imaging using intravascular probes is often limited due to the image intensity distortion caused by the signal inhomogeneity associated with the placement of the probe. Methods developed for the phased-array and other surface coils are not as successful for intravascular imaging since the conducting structures of the RF-receiving devi...

Review of Intensity Inhomogeneity Correction Methods for Brain Mri Images

Intensity inhomogeneity is a smooth intensity change inside originally homogeneous regions. The intensity inhomogeneity degrades performance of image processing algorithms. Intensity inhomogeneity correction methods are important image processing algorithms which are used to reduce the inhomogeneity. Brain image intensity inhomogeneity correction is one of the most important parts of clinical d...

Mri Sequences

An MRI sequence is an ordered combination of RF and gradient pulses designed to acquire the data to form the image. In this chapter I will describe the basic gradient echo, spin echo and inversion recovery sequences used in MRI. The data to create an MR image is obtained in a series of steps. First the tissue magnetisation is excited using an RF pulse in the presence of a slice select gradient....
