The relaxometry hype cycle

Frontiers in Physiology, 2023
Relaxometry is a field with a glorious and controversial history, and no review will ever do it justice. It is full of egos and inventions, patents and lawsuits, high expectations and deep disillusionments.

Voxel-based relaxometry: a new approach for analysis of T2 relaxometry changes in epilepsy

NeuroImage, 2004
The measurement of the T2 relaxation time (T2 relaxometry) had been established as a reliable tool for the assessment of certain conditions such as temporal lobe epilepsy. The standard procedure for analysis of T2 data uses manually drawn regions of interest (ROIs).

Placental MRI Predicts Fetal Oxygenation and Growth Rates in Sheep and Human Pregnancy

Advanced Science, 2022
Magnetic resonance imaging (MRI) assessment of fetal blood oxygen saturation (SO2) can transform the clinical management of high‐risk pregnancies affected by fetal growth restriction (FGR). Here, a novel MRI method assesses the feasibility of identifying

T2 Relaxometry of the Hippocampus at 3T [PDF]

American Journal of Neuroradiology, 2007
T2 mapping is useful for identifying and quantifying abnormalities of the hippocampus and amygdala. It is particularly useful in the presurgical evaluation of patients with temporal lobe epilepsy and for the identification of bilateral hippocampal sclerosis (HS).
