Determination of fallopian tubal patency by magnetic resonance imaging

摘要

This invention is a method for obtaining improved NMR images of the uterine cavity and fallopian tubes comprising imjecting a physiologically acceptable solution of a chelate of a parmagnetic material into the uterus under sufficient pressure to cause the solution to pass through the fallopian tubes and obtaining an enhanced NMR image of the tissue surrounding the fallopian tubes. The chelates and the injection solutions thereof do not include carbohydrate groups or other compounds which might support growth of Staphylococcus aureus or other pathological miroorganisms in the peritoneal cavity. Kits including contrast medium and non-metallic uterine balloon catheters suitable for use with NMRI procedures are also included within the scope of this invention.
