Clinical Indications To Mri In Pregnancy Mri Of Fetal And Mat Objective. the purpose of this study was to evaluate the effects of clinical 3 t mri during pregnancy on fetal growth and neonatal hearing in neonates at low risk of congenital hearing impairment or of brain or chromosomal abnormalities. materials and methods. this single center retrospective case control study included consecutively born healthy neonates exposed in utero to 3 t mr during mri. Introduction. imaging studies are important adjuncts in the diagnostic evaluation of acute and chronic conditions. the use of x ray, ultrasonography, ct, nuclear medicine, and mri has become so ingrained in the culture of medicine, and their applications are so diverse, that women with recognized or unrecognized pregnancy are likely to be evaluated with any one of these modalities 1.
Clinical Indications To Mri In Pregnancy Mri Of Fetal And Mat Additional precautions do exist to address fetal safety. 4 6 the us food and drug administration (fda) requires labeling of mri scanners to indicate that the safety of mri for the fetus has not yet been established. 7 testing for pregnancy prior to mri is advised, and when pregnancy is confirmed, a few specific points of consideration are. The omega hp gradient system (philips healthcare) was used with maximum amplitude of 45 mt m and maximum slew rate of 200 t m ms. maternal and fetal mri was performed during all three trimesters for varying clinical maternal and fetal indications, thus requiring varying ex amination types and mri sequences. 3.6. main indications for emergency mri during pregnancy. the most common clinical indications for an emergency mri during pregnancy include both maternal and fetal conditions. in all these cases, us usually represents the first diagnostic choice; however, if the us does not lead to a diagnosis of certainty, it may be useful to resort to mri. Mri also has the advantage of providing non operator dependent, detailed cross sectional anatomy. overall, mri use during pregnancy is increasing due to the lack of ionizing radiation, increasing availability, and advances in fetal mri, which has steadily grown since its inception in the mid 1980s [1,2]. despite the general acceptance of mri as.

Pregnancy (ie, second or third trimester).1,4,7 however, it should be noted that, to date, no known literature has delin eated specific consequences for fetuses exposed to noncontrast mri during any trimester,4,5 and imaging policies vary between institutions as a result. first trimester during the first trimester, fetal cells are implanting.
