It is important to evaluate the level of contrast provided by CT and MRI for soft and hard tissues of brain, and how human eye perceive these images. An understanding about these concepts helps in choosing the right imaging modality to observe a particular brain tissue.Ramya Balakrishnan...
By increasing the contrast of an image, it will be easy for analysing because of detailed information. This increase in contrast can be done by number of ways in image processing. This paper compares different methods of enhancement of brain MRI using histogram based techniques. 展开 ...
Contrast-enhanced magnetisation transfer MRI in small lung metastatic lesions of the brain Objective To study the brain small metastatic focus from primary lesion of the lung by means of MR imaging with contrast enhanced magnetization transfer (M... Y Miao,W Lin,YE Qian,... - 《Chinese ...
INTRODUCTION: The aim of this study is to investigate perfusion characteristics of brain arteriovenous malformation (AVM) by means of MRI perfusion-weighted imaging (PWI). METHODS: Forty-three patients with brain AVM were prospectively included and investigated by PWI-MRI. Diagnosis of type of diseas...
Contrast-enhanced T1-weighted spin-echo magnetic resonance imaging (MRI) has demonstrated that Gd-diethylenetriaminepentaacetate (Gd-DTPA), which normally does not cross the blood-brain or blood-CSF barriers, does so approximately 40 min after administration of glucose to a vitamin B1 deficient rat....
As these measures can reflect the integrity of the blood-brain barrier and tumor vascular perfusion and permeability, these features may also reflect features that are associated with different tumor grades. Several studies have suggested that high-grade gliomas have greater vascular permeability, possibl...
The purpose of this study was to develop a technique for differentiating between recurrent brain tumors and treatment-related changes, such as radiation necrosis, using dynamic MRI. Ninety-five patients with intracranial mass lesions were evaluated using T1-weighted fast spin-echo (FSE) MRI at 1.5...
