Abstract
BACKGROUND In current literature the prognosis of trisomy 18 is mainly described as inevitably lethal. After intervention of parental organisations infants have been treated with cardio surgery in the USA, later in Europe as well with good results. We report the consequences of this and similar developments on our pre- und postnatal approach after diagnosis in our department. PATIENTS AND CASE REPORTS: 2 parents decided to carry the child to term after the recommendation for abortion. According to standard perinatological aspects one child was vaginally delivered, the second with Caesarean section. After informed consent with the parents we planned a supportive management without more resuscitation than stimulation and ventilation by mask. Both children could be stabilised with nasal CPAP. The first one had been operated on a double outlet right ventricle at the age of 6 months, the second needed to be operated for diaphragm hernia. The third child had been delivered by emergency Caesarean section. A bilateral choanal atresia had been operated in the first week of life, a double outlet right ventricle at the age of 15 days. One child is fed by a nasogastric tube, one is bottle-fed and one had a percutanous gastric tube until he died due to septicaemia, all have statomotorically retardation and had periods of pulmonary hypertension. The social situation of the families is characterised by a stable parental relationship and a safe socio-economical status. None of the children had an acute lethal malformation. DISCUSSION In single cases a prospective management in patients with trisomy 18 can be possible. Besides medical issues, the emotional parental wish, their social network and economical status are crucial. CONCLUSION The prognosis of trisomy 18 is poor. 3 patients and 20 months do not allow any general statements. However, our recent experience and the courses in the recent literature show that in single cases a more prospective management is possible.

Abstract
CT angiography is the imaging modality of choice for the pre- and postsurgical evaluation of patients with pathologies of the thoracic aorta. The purpose of this review is to familiarize the reader with the technical principle, recent technical developments and requirements for specific examination protocols and image interpretation, and to highlight common pathologies and findings.

Abstract
OBJECTIVES To evaluate the image quality of time-resolved contrast-enhanced MRA (tr-MRA) employing echo-sharing with stochastic trajectories for the bilateral examination of the hands. METHODS In this institutional review-board approved study, Tr-MRA was compared with multiphasic contrast-enhanced MRA (mp-MRA) featuring sub-systolic venous compression in 20 healthy volunteers at 3.0 T using the following settings: TR/TE: 2.8/1.2 ms, flip angle: 25°, acceleration factor: 4, effective voxel size: 0.9 × 0.8 × 0.9 cm, acquisition time 4.9 s per 3D volume. RESULTS With tr-MRA the arterial first-pass contrast agent transit is clearly seen. On average the contrast agent arrived 34 s post-injection and reached the proper digital arteries after 44 s. The mean arterio-venous window was 13 s. Bilateral contrast enhancement was asynchronous in 56-62%. On a semiquantitative scale (0 = non-sufficient to 4 = excellent) tr-MRA (mp-MRA) yielded an average ranking of 2.8-3.6 (3.1-3.8) in the greater and intermediate sized segments and 1.3-2.0 (1.6-2.3) in the proper digital arteries. CONCLUSION Compared with established multiphasic ce-MRA, time-resolved MRA allows a four times faster acquisition. It reflects the natural haemodynamics of the hand arteries with no need for sub-systolic venous compression and may be beneficial in the detection of hand circulation disorders. Image quality is comparable to mp-MRA. In both techniques depiction of the proper digital arteries is limited.
