Conventional MRI studies reveal focal signal deviations, traditionally called lesions or “plaques” throughout the white matter (WM) and less frequently also in grey matter (GM) of brain and spinal cord in both T2 and T1 weighted scans.

Nevertheless, whilst T1-weighted PM MRI may suffer from the lack of contrast, this sequence may still have an important role in NE for excluding other brain abnormalities such as structural abnormalities and intracranial bleeds. 5, providing complimentary information to T2-weighted PM MRI.

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 ...

So-called T1-weighted (T1W) images are produced by keeping TR and TE relatively short. Under these conditions, contrast between structures is based primarily on their T1 relaxation differences. T2-weighted (T2W) images are produced by using longer TR and TE times.

In the first 7 patients a T1-weighted sequence and a T2-weighted fat saturated sequence were acquired in the axial plane (relative to the anatomical position), before contrast agent administration at both time points. In 27 patients postcontrast, T1-weighted, fat saturated sequences were acquired in axial and coronal planes at both timepoints.

Dynamic contrast enhanced (DCE) MRI – T1 weighted images are obtained quickly and at high frequency following administration of intravenous contrast agent. Pharmacokinetic modelling of the signal intensity over time can then be used to parametrically map tissue parameters that affect contrast agent kinetics and that may alter in disease.

6. What do T1-weighted images show? What TR and TE are needed to achieve T1-weighting? 7. What do T2-weighted images show? What TR and TE are needed to achieve T2-weighting? 8. How are T1 and T2 images different in what they show? That is, why might someone use a T2 image instead of a T1 image, or vice-versa? 9. What do T2* images show?

The breast MRI protocol includes a T2-weighted sequence, diffusion-weighted imaging (DWI) sequence, and dynamic contrast-enhanced (DCE) series using a bilateral, 3D, fat-suppressed, T1-weighted sequence with 80-100 second temporal resolution. The general imaging parameters are included in Table 1 …
