摘要: In order to later identify the location of a biopsy or surgery, various means and methods for permanently and non-surgically marking selected tissue in the human body are used. Later visualization of the markers is readily accomplished using state-of-the-art imaging systems.

摘要: A magnetic resonance imaging (MRI) method imposes void planes on tissue to be imaged, which may form a grid pattern of lines which, when later imaged, produces a reference void in the image. This is especially useful in studies of the heart where the contraction and relaxation of the heart can thus be measured. Also for static tissue the method is useful for radiation therapy port planning. The grid reference or void planes are formed by a simple use of an RF pulse in conjunction with the use of a slice select gradient which provides sufficient power so that those protons in the grid are saturated so that in the later imaging step there will be significant spin echo signal difference between the grid imposed areas and the remaining regions of the tissue.
