“…This requires antenatal assessment of renal parenchyma and amniotic fluid volume, both of which can be done with modern MR image acquisition and processing. 67,68 While Fetal MRI does not represent a gold-standard for diagnosis, it is recognised to be a useful adjunct in the evaluation of identified pathology. 69,70 Fetal MR has further prognostic use in evaluating the renal parenchyma in detail, assessing for the presence of cysts and parenchymal dysplasia, detailed in the illustrative cases below.…”

This illustrative review depicts the evolving role of magnetic resonance imaging (MRI) in the diagnosis and prognostication of anomalies of the fetal body (here including head and neck, thorax, abdomen and spine). A review of the current literature describing the state-of-theart in antenatal imaging for diagnosis and prognostication of congenital anomalies is coupled with illustrative cases in true radiological planes with viewable 3D video models that demonstrate the potential of post-acquisition reconstruction protocols.Within, we will discuss benefits and limitations of fetal MRI across the breadth of conditions included: from anomaly detection, classification and prognostication as well as defining the role of imaging in the decision to proceed to prenatal intervention. Reference will also be made to the current capabilities of ultrasound and we will explore potential ways in which the two may perform complimentary roles in the future of prenatal imaging.

“…An apparent diffusion coefficient (ADC) value is calculated for each voxel within an image. Fetal kidney ADC decreases with increasing gestation, but the pattern may be quite different in urinary tract anomalies . Normally, the fetal kidney shows restricted diffusion similar to that of the mother's kidneys.…”

“…Lack of a normal DWI bright signal in the renal fossae without evident renal signal elsewhere is consistent with renal agenesis rather than ectopic kidneys . It has also been suggested that DWI with ADC determination is useful for predicting renal function in the presence of posterior urethral valves …”

The use of fetal MRI for renal and urogenital tract anomalies

et al. 2019

Fetal anomalies are detected in approximately 2% of all fetuses and, among these, genitourinary tract abnormalities account for 30% to 50% of all structural anomalies present at birth. Although ultrasound remains the first line diagnostic modality, fetal MRI provides important additional structural and functional information, especially with the development of faster sequences and the use of functional sequences. The added value of MRI-based imaging is three-fold: (a) improvement of diagnostic accuracy by adequate morphological examination, (b) detection of additional anomalies, and (c) in addition, MRI has the potential to provide information regarding renal function. In this review, we describe the role of fetal MRI in the anatomical evaluation of renal and urogenital tract anomalies, and we also touch upon the contribution of functional MRI to the diagnostic workup of these conditions.

“…27,28 The DWI sequence may be useful in defining the renal parenchyma by evaluating increased signal intensity on DWI and decreased signal on ADC maps. 29 However, the case series are small, and further studies are necessary to fully define the benefits of MRI in evaluating and managing patients with LUTO. 30 Sonographic evaluation of the posterior fossa and the spine is limited by fetal position, maternal body habitus, oligohydramnios, and ossification of the fetal skull.…”

Fetal magnetic resonance imaging (MRI) has become an important adjuvant to high-quality ultrasound once fetal structural anomaly is identified. There are recently developed advanced techniques such as provision of volumetric data, spectroscopy, and functional MRI. Changes in local susceptibility caused by blood breakdown products, echo-planar imaging (EPI) sequences [i.e., diffusion-weighted imaging (DWI) and apparent diffusion coefficient (ADC)] are especially sensitive to hemorrhage and edema. These novel sequences are particularly useful for assessment of fetal ischemic and hemorrhagic brain lesions. Prenatal MRI has been increasingly adopted in assessment and follow-up after in utero surgeries of twin-twin transfusion syndrome, congenital diaphragmatic hernia, lower urinary tract obstruction, and myelomeningocele. Development of guidelines to better define the role of fetal MRI in relation to prenatal diagnostic ultrasound can reduce the variation of sequence protocols, magnetic field intensity, as well as the use of gadolinium performed in different centers. Novel sequences may be used for research purposes, but safety concerns of obstetric MRI cannot be overlooked. The current utilities and future prospects of MRI in perinatal medicine are updated in this article.
