ABSTRACT
El radiólogo debe ser capaz de reconocer los signos de la malrotación intestinal en la imagen al tratarse de una entidad patológica con complicaciones potencialmente letales, como el vólvulo de intestino medio. Para diagnosticarla correctamente, es tan importante que exista un índice de sospecha clínica elevado como que el radiólogo sepa reconocer los signos específicos de malrotación y las variantes de la normalidad que pueden conducir a un diagnóstico erróneo. Aunque la posición no retroperitoneal de la tercera porción duodenal en ecografía, TC o RM parece ser un signo fiable para el diagnóstico, el tránsito gastrointestinal continúa siendo el estándar de referencia para ver la unión duodeno-yeyunal en una posición anómala. Nuestro objetivo es revisar los principales signos radiológicos de esta enfermedad y hacer hincapié en el papel de la ecografía para diagnosticar el vólvulo de intestino medio (AU)
Radiologists must be able to recognize the imaging signs of intestinal malrotation because this condition can lead to potentially lethal complications such as midgut volvulus. The correct diagnosis depends on both high clinical suspicion and the radiologist's ability to recognize the specific signs of malrotation and the normal variants that can lead to the wrong diagnosis. Although the location of the third portion of the duodenum outside the retroperitoneal area on ultrasonography, CT, or MRI seems to be a reliable sign of malrotation, the gold standard for determining whether the duodenojejunal flexure is in an abnormal location continues to be the upper gastrointestinal series. In this article, we review the most important imaging signs of malrotation and emphasize the role of ultrasonography in diagnosing midgut volvulus (AU)

OBJECTIVE: To assess the role of magnetic resonance imaging (MRI) in the prenatal diagnosis of neural tube defects (NTDs). BACKGROUND: NTDs comprise a heterogeneous group of congenital anomalies that derive from the failure of the neural tube to close. Advances in ultrasonography and MRI have considerably improved the diagnosis and treatment of NTDs both before and after birth. Ultrasonography is the first technique in the morphological study of the fetus, and it often makes it possible to detect or suspect NTDs. Fetal MRI is a complementary technique that makes it possible to clear up uncertain ultrasonographic findings and to detect associated anomalies that might go undetected at ultrasonography. The progressive incorporation of intrauterine treatments makes an accurate diagnosis of NTDs essential to ensure optimal perinatal management. The ability of fetal MRI to detect complex anomalies that affect different organs has been widely reported, and it can be undertaken whenever NTDs are suspected. CONCLUSION: We describe the normal appearance of fetal neural tube on MRI, and we discuss the most common anomalies involving the structures and the role of fetal MRI in their assessment. KEY POINTS: ⢠To learn about the normal anatomy of the neural tube on MRI ⢠To recognise the MR appearance of neural tube defects ⢠To understand the value of MRI in assessing NTDs.
ABSTRACT
A urethral dysuria cystograph (CUMS (Cistografia Ureteral Miccional Seriada)) is the first diagnostic procedure, by means of x-rays, to evaluate bladder-urethral reflux. It consists of a bladder catheter to administer a radiopaque contrast dye through the ureter. To use the aforementioned technique without any asepsis measures and without knowledge about it can lead to possible complications. By means of a retrospective study using a sample of 181 patients, the authors have evaluated the incidence of possible complications and/or subsequent discomfort due to a urethral dysuria cystograph (CUMS). As final results, by means of an after test telephone call, the authors observed that 96.7% of the children who underwent this technique did not manifest any type of complication nor urinary discomfort.

La CUMS (Cistografía Ureteral Miccional Seriada) es el primer procedimiento diagnóstico, por rayos X, para la evaluación del reflujo vesicoureteral. Consiste en un sondaje vesical para administrar un contraste radiopaco a través de la uretra. Realizar dicha técnica sin unas medidas de asepsia y sin conocimientos de la misma puede dar lugar a posibles complicaciones. Mediante un estudio retrospectivo, con una muestra de 181 pacientes, se ha valorado la incidencia de posibles complicaciones y/o molestias posteriores a una CUMS. Como resultados finales, a través de una llamada telefónica tras la prueba, se ha observado que en el 96,7% de los niños no se ha manifestado ningún tipo de complicación, ni molestia urinaria(AU)
