[Quantification of microvascular obstruction in acute myocardial infarction using cardiac MRI].

Published in RöFo : Fortschritte auf dem Gebiete der Röntgenstrahlen und der Nuklearmedizin

Our study shows that the time delay between contrast media injection and image acquisition has a significant impact on the delimitable extent of MO and infarct size.

[Preoperative accuracy of selective laser sintering (SLS) in craniofacial 3D modeling: comparison with patient CT data]....

Published in RöFo : Fortschritte auf dem Gebiete der Röntgenstrahlen und der Nuklearmedizin

We found a high accuracy of SLS 3D models, which is due to a high precision in the modeling process and to the small voxel size of patient CT data achieved by MSCT. Anatomical landmarks in patient and model CT data sets and on the 3D model were able to be accurately reproduced, which is important for preoperative planning.

[First experiences with intravenous port systems authorized for high pressure injection of contrast agent in multiphasic...

Published in RöFo : Fortschritte auf dem Gebiete der Röntgenstrahlen und der Nuklearmedizin

The intravenous high pressure port systems are equivalent to standard systems with regard to implantation and implementation. Intravenous chemotherapy can be performed as usual. The advantage is the possibility of multiphasic CT with authorized flow rates of up to 5 ml/sec.

[Automatic phase point determination of minimal motion reconstruction intervals with motion maps in ECG-gated CT diagnos...

Published in RöFo : Fortschritte auf dem Gebiete der Röntgenstrahlen und der Nuklearmedizin

Calculation of the Agatston score requires selection of the proper reconstruction interval to guarantee the assignment of patients into the appropriate risk category. By using motion maps for phase point determination, the amount of necessary reconstruction can be minimized and the assignment to different risk groups is also reduced.

Image data compression in diagnostic imaging: international literature review and workflow recommendation.

Published in RöFo : Fortschritte auf dem Gebiete der Röntgenstrahlen und der Nuklearmedizin

Imaging equipment manufacturers are encouraged to improve the compression technology of their imaging devices (e. g. freely selectable compression ratios in the output filter). Double compression should be strictly avoided. Lossless compression formats should be switched off.

[Multicenter analysis of tolerance and clinical safety of the extracellular MR contrast agent gadobenate dimeglumine (Mu...

Published in RöFo : Fortschritte auf dem Gebiete der Röntgenstrahlen und der Nuklearmedizin

MultiHance is a safe and very well tolerated contrast agent for magnetic resonance imaging (MRI) with a profile and frequency of adverse events similar to other extracellular MR contrast materials.

[Comparison of two automatic evaluation methods on Images of the CDMAM test phantom].

Published in RöFo : Fortschritte auf dem Gebiete der Röntgenstrahlen und der Nuklearmedizin

Methods that dispense with visual inspections to determine the performance of X-ray units for mammography can be applied in the acceptance test or the yearly constancy tests according to the German X-ray directive ( section sign 16). The CDCOM program cannot be characterized fully because the data is not complete. Finally the detection methods are ...

[Retrospective 5-year analysis of MR-guided biopsies in a low-field MR system].

Published in RöFo : Fortschritte auf dem Gebiete der Röntgenstrahlen und der Nuklearmedizin

MR-guided biopsy can be performed safely and precisely in a low-field MR system and are a supplement to US or CT-guided biopsies.
