[Evaluation of muscle layer of the uterine body by dynamic MRI]

Gd-DTPA enhanced dynamic MR imaging was performed in 11 normal uteri using a 1.5-T MR unit in order to analyze normal dynamic patterns. After intravenous bolus administration of Gd-DTPA, dynamic study was performed with serial imaging-gradient echo (FLASH). In most cases of normal uteri, early enhancement was shown in peripheral zone that was similar to be junctional zone, forming inner region of muscle layer.
