Optimal timing of breast MRI examinations for premenopausal women who do not have a normal menstrual cycle.
OBJECTIVE
The objective of this article is to describe a method for timing breast MRI examinations corresponding to the follicular phase of the menstrual cycle in premenopausal women without cyclical menses, thereby reducing the number of false-positive findings and nondiagnostic examinations.


CONCLUSIONS
Serum progesterone concentrations corresponding to the follicular phase of a normal menstrual cycle can aid in optimal scheduling of breast MRI examinations for premenopausal women who lack cyclical menses.
