Prenatal Tanıda Fetal Manyetik Rezonans Görüntülemenin Rolü

ABSTRACT Objective The aim of this study is to investigate the fetal MRI indications preferred by clinicians in our tertiary care center and to reveal the additional diagnostic contribution of MRI to ultrasound findings. Material and Method Between 2016-2018, 322 cases who underwent fetal MRI were evaluated retrospectively. Fetal lesions were classified according to organ systems and indications of clinicians were determined. Prenatal fetal ultrasound and MRI results were evaluated. Results Distribution of indications of 322 fetuses with fetal MRI; Central nervous system anomalies in 138 (42.8%), placental anomalies in 99 (30.7%), genitourinary system anomalies in 36 (11.2%), respiratory system anomalies in 18 (5.6%), 17 (5.3%) maternal factor, 13 (4.0%) head, neck, face anomalies and 1 (0.4%) fetal factor. When all indications were examined, 13 (4.03%) patients had additional findings with MRI. Central nervous system anomalies were the most common additional finding with 7 cases, fetal MRI contributed 5.07% in this group. There were 3 additional findings (8.33% additional contribution) in the group with genitourinary system abnormalities, 2 additional findings (11.7% additional contribution) in the maternal indications group and 1 additional finding (5.55% additional contribution) in the group with respiratory system anomalies, respectively. Conclusion Fetal MRI is increasingly used for proper perinatal management and counseling in cases where ultrasonography is inadequate. The availability of MRI devices, the increase in expertise in this field and the advancements in MRI technology will result in the more widespread use of this modality in the field of Perinatology.
