Abstract
|
|
|
Rationale ad objectives of this study were to investigate the alterations of signal intensities, relaxation times (T1 and T2) and phosphorus metabolites of dog thigh muscle after x-ray irradiation by magnetic resonance imaging (MRI) and 31P
magnetic
resonance spectroscopy (MRS).
@ES The results were as follows:
@EN 1. MR signals showed no significant morphologic changes on T1-and T2-weighted images until 56 days after 5,000 cGy irradiation. In cases of 10 ,000 cGy irradiation, however, they began to produce signal changes only on T2-weighted images
after
28
days with extensive high signal intensities after 42 days.
