Improvements in MRI techniques widen the indications for fetal brain imaging and fetal brain injury represents the third indication of fetal brain magnetic resonance imaging (MRI) after the evaluation of suspected central nervous system (CNS) malformations and ventricular dilatation. Optimal MR imaging technique is necessary in order to collect as much data(More)
OBJECTIVES To identify important factors in the differential diagnosis of renal cysts associated with hyperechogenic kidneys. METHODS This was a retrospective multicenter study. We identified 93 fetuses presenting between 1990 and 2002 with hyperechogenic kidneys and which had a diagnosis of nephropathy confirmed later. We analyzed retrospectively the(More)
Cerebral maturation in the normal human fetal brain was investigated by in utero localized proton MR spectroscopy ((1)H MRS). Fifty-eight subjects at 22-39 weeks of gestational age (GA) were explored. A combination of anterior body phased-array coils (four elements) and posterior spinal coils (two to three elements) was used. Four sequences were performed(More)
OBJECTIVES To assess the use of diffusion-weighted magnetic resonance imaging (DW-MRI) in the evaluation of the fetal kidney and to estimate age-dependent changes in the apparent diffusion coefficient (ADC) of normal and pathological fetal kidneys. METHODS DW-MRI was performed on a 1.5-T machine at 23-38 gestational weeks in 51 pregnant women in whom the(More)
OBJECTIVE The objective of our study was to assess the rate of abnormal radiographic findings in the most frequent osteoarticular locations of traumatic injury in a pediatric population. SUBJECTS AND METHODS During two periods of 12 weeks each, all patients admitted to the pediatric emergency department for osteoarticular trauma who underwent radiography(More)
OBJECTIVE To determine the effect of implementing a daily lung ultrasound round on the number of chest radiographs and chest computed tomography (CT) scans in a polyvalent intensive care unit (ICU). STUDY DESIGN Retrospective study comparing two consecutive periods. PATIENTS All patients hospitalized for longer than 48 hours in a polyvalent ICU. (More)
PURPOSE OF REVIEW Magnetic resonance imaging is playing an increasingly prominent role in depicting brain maturation, especially gyral formation that follows a temporospatial pattern, and in detecting developmental abnormalities of the cortex and other brain sectors. Knowledge of the technical advantages and limitations of in-utero magnetic resonance(More)
OBJECTIVES We evaluated functional outcome of kidneys with fetal urinoma associated to ureteropelvic junction obstruction. METHODS We retrospectively reviewed 5 cases of antenatally diagnosed urinoma associated to hydronephrosis. Prenatal imaging work-up consisted of ultrasound (US) and magnetic resonance (MR) examination. Differential renal function was(More)
