TR and TE in MRI: A Quick Q&A Guide to Repetition and Echo Times

A new educational post from MRI Questions explains repetition time (TR) and echo time (TE) in MRI, covering how they control image contrast (T1, T2, proton density) and sequence selection. Aimed at trainees and technologists.

• Educational Q&A resource from Elster's MRI Questions website.
• Covers fundamental MRI contrast parameters: TR influences T1 weighting, TE influences T2 weighting, and both affect proton density contrast.
• No study data; purely a teaching reference for radiology residents and technologists.
