Contrast in GRE
I have found an explanation of GRE contrast in the book "MRI, The Basics - Ray Hashman Hashemi, William G. Bradley Jr., Christopher J. Lisanti - 3rd Ed. Chapter 20. Gradient Echo: Part I (Basic Principles)". Here is a link with a screenshot https://photos.app.goo.gl/88e2iJ7amEQTWg1r9rnA "> https://photos.app.goo.gl/88e2iJ7amEQTWg1r9rnA "longer TR enhances T1 weighting". And a table in the end of the chapter. But there is a contraversions opinion in other sources. For example, http://www.mri-q.com/spoiled-gre-parameters.html.rnrnThere is described that "The lengthening of TR cause increase PD weighting, and shortening TR increase T1 weighting".
