The diagnostic role of "in utero” magnetic resonance imaging

Abstract
Objective: To assess the diagnostic potential of Magnetic Resonance Imaging (MRI) in the management of ultrasonically diagnosed congenital anomalies.
Patients and Methods: Ninety-two patients were included into the study after the ultrasonic diagnosis of an abnormality. Sixty-three of these patients were affected by an abnormality of the central nervous system (CNS) and 29 by abnormalities in other apparatuses. The GRE technique was used to obtain T1 and T2 star-weighted images.
Results and Discussion: Satisfactory imaging was obtained in all but one case. In order to define the "reliability" of MRI for a given condition, a diagnostic score was designed and separately given by the obstetrician and the radiologist involved in the case. MRI scored less than ultrasonography for abnormalities of the fetal contour and for large and complex distortion of the CNS as holoprosencephaly. For subtle midbrain anomalies, as well as for neuronal migration disorders, MRI definitely was superior to sonography. For other anomalies, as for example congenital diaphragmatic hernia, MRI was better than conventional techniques in assessing prognosis and outcome, but less reliable in assessing associated anomalies.
MRI seems to be a valuable adjunct to us for prenatal diagnosis of only selected fetal anomalies and requires precise guidelines in a multidisciplinary approach to prenatal pathology.
