There are many inventions described herein as well as many aspects and embodiments of those inventions. A thigh compression device and technique to control, time, delay and/or prevent excessive early venous enhancement relative to arterial enhancement and thereby improve and/or enhance MRA images, including peripheral MRA images. In one embodiment, the present invention uses a curved strip of material which is longer on the superior edge and shorter along the inferior edge. When wrapped around the conical or conal-like shape of the thigh of a subject (for example, a human), the thigh compression device more uniformly conforms to and/or fits around the thigh, providing more even/uniform compression as well as reducing, minimizing and/or eliminating significant movement of the thigh compression device towards the knees of the subject. Notably, a snug fit on the thighs may also enable the thigh compression device to be inflated with less fluid (for example, air) which is faster and less cumbersome for the operator.
