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".

Crash cart requirements for contrast
We are an outpatient surgical center with an MRI department and on-site physicians and we frequently have contrasted exams. What are the MRI department-specific requirements for the crash cart? We currently have a fully loaded crash cart that is honestly stocked with a lot of medications we would never administer even during a reaction. So in an effort to cut restocking costs, what are we REQUIRED to have on hand? And which organization would govern that? (The ACR white paper on MRI safety doesn't seem to cover this topic.)

Brain T2FS postcontrast
What is the advantage of T2 FS imaging of the brain if 3 planes of postcontrast T1's are obtained.
Thanks.
