Stents
Employer relates that any cardiac stent implanted after 2008 is safe on ANY MRI scanner within our system. This ranges from 0.3 Open scanners to 1.2 High field Open and 1.5 and 3T closed systems.
Contrarily, the manufacturer data on certain stents states 1.5 or 3 T ONLY, but we are urged to scan on an open if implanted after 2008. Does anyone have any type of testing documentation that this is safe? I'm not so much worried about the field strength as I am the magnetic field orientation as the defining safety issue.

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".

Help - Lateral Knee Pain
Hi Everyone. I got an MRI scan recently which diagnosed a small tear in the posterior horn of the medial meniscus. I am confused because the pain is lateral around the fibula. Looking at the scan it looks like there is a lot of fluid around the fibula, can anyone tell me if this looks normal?Thanks so much for any help

Proton excitation from B0 to B1
I'm new to MRI imaging and currently taking an introductory course online. I understand that the introduction of a small magnetic field/RF pulses on top of the static magnetic field (B0) excites protons into a high energy state (B1). Does this mean that the protons are excited from a spin that is parallel to the longitudinal B0 plane to one that is antiparallel to the longitudinal B0 plane, or that the proton spin is excited from one that is aligned/polarized with B0 to one that is either parallel or antiparallel to B0 in the B1/xy plane?
