This effect might be caused by the magic angle effect (Murray et all 2007) which is an artifact, but could also be explained by the thickness of the ligament on MRI slices. ...

Q15. Is the relative difference in intensity between gray and white matter greater on T1 or T2 images? 3.2 T2 Imaging. T2 images are intended to measure only differences between tissues in the rate at which the transverse magnetization decays. Look at Figure 5.8 in your textbook. As an example, the T2 images used in this laboratory were ...

Images with T2* contrast are very useful for functional MRI of the brain, as will be seen in Chapter 3. For clinical purposes, images with T2 contrast are more useful. T2 differs considerably between normal brain tissue and tumor tissue or infarcted tissue. T2-weighted images are acquired using spin echoes (§2.4) rather than gradient echoes.

In the brain, T2* is usually about half of T2. Changes in T2* are the most pronounced consequence of the BOLD effect; changes in T2 are also present, but are smaller (T2* and T2 both increase with blood oxygen level). The reciprocal of T2* is called R2*. T2(T2( measures the relaxation time scale difference between T2 and T2*.

Magnetic resonance imaging is used to image and distinguish gray matter and white matter hyper intensities which appear as bright signals on the T2-weighted MRI images [2]. Using structural MRI, variations in water content in different parts of the brain provide contrast, which allows for the differentiation between the gray matter and the ...

COMPARATIVE IMAGING STUDY USING A MULTI-MODALITY …
The aim of our study was to apply the newest myelin-selective MRI method, multi-component Driven Equilibrium Single Pulse Observation of T1 and T2 (mcDESPOT) in a controlled clinical MS pilot trial. This study was designed to assess the capabilities of this new method to explain differences in disease course and degree of disability in subjects ...

In MRI, the contrast in the T2 weighted images stems from the T2 relaxation times of the phantom constituents (TMM and glass beads): since the glass beads have an extremely short T2 value (< 100 s), they effectively produce no signal in a T2-weighted image and …
