The two basic types of MRI images are T1-weighted and T2-weighted images, often referred to as T1 and T2 images. The timing of radiofrequency pulse sequences used to make T1 images results in images which highlight fat tissue within the body.

T2-weighted images are a type of magnetic resonance imaging (MRI) that highlights differences in the T2 relaxation times of various tissues. T2 relaxation refers to the decay of transverse magnetization (Mxy) over time after an external radiofrequency (RF) pulse is applied.

Nov 30, 2022 · This article contains a list of commonly and less commonly used MRI pulse sequence abbreviations and their meaning. If available, an explanation is included in a separate article. T2*: T2 star. PRESS: point resolved spectroscopy.

Dec 2, 2015 · Two Basic MRI of the Lumbar Spine Images (T1 AND T2 Images) There are two basic types of MRI images that differ by the timing of the radiofrequency pulses, named T1-weighted images and T2-weighted images. T1 images highlight FATty tissue. T2 images highlight WATER >> FAT within tissues. The contrast between these tissues creates the amazing ...

Sep 18, 2024 · Figure 5 is a real disc-level T2-weighted axial MRI image in which I have outlined the disc, (white) the thecal sac, (green) and the posterior arch (yellow). I have also colored the left neural foramen red and marked the right side of the image.

T2* (T2 star) MRI is a specialized magnetic resonance imaging (MRI) technique that capitalizes on the T2* relaxation time. This relaxation time measures how quickly the magnetization of protons decays due to magnetic field inhomogeneities and magnetic susceptibility differences within …

T2*-weighted imaging is an MRI sequence to quantify observable or effective T2 (T2* or " T2-star "). In this sequence, hemorrhages and hemosiderin deposits become hypointense. [2]

Sep 4, 2022 · Generally these sequences exploit what is referred to as T2* (T2 star) which is highly sensitive to small perturbations in the local magnetic field. The most sensitive of these sequences is known as susceptibility weighted imaging (SWI) and is also able to distinguish calcium from blood.

Contrast-enhanced MRI of the brain was performed on a 3.0 Tesla scanner utilizing the following sequences: Sagittal T1, axial T2, axial FLAIR, axial GRE images, axial DWI, axial ADC, axial T1, coronal T2, axial T1 post-contrast and coronal T1 post-contrast.
