[How to finance and increase the appeal of rheumatology training : view of the Association of Rheumatology Clinics in Germany (VRA) on challenges and successful strategies]. / Finanzierung und Attraktivitätssteigerung der Weiterbildung zum Facharzt für Rheumatologie : Herausforderungen und erfolgreiche Strategien aus Sicht des Verbands der Rheumatologischen Akutkliniken (VRA).

Due to the general lack of physicians in German hospitals new approaches are necessary to be successful in acquiring doctors for training in inpatient rheumatology.Although the financing of rheumatology education is still included in the general payment of hospitals, currently the diagnoses-related groups,,as it has already been fixed in the regulation on hospital care rates in Germany since 1994, new strategies may help to improve the financial situation of hospital units.The implementation of a binding structural quality, endorsed by the Association of Rheumatology Clinics in Germany (VRA), as well as the application of clinical pathways will optimize revenues.Further financial improvements can result from the implementation of case management, the implementation of interdisciplinary treatment, the promotion of a high quality treatment, from a differentiated approach towards outpatient treatment and a specialization within inpatient rheumatology units.Incorporating these strategies the advantages may not only affect the financial situation of hospitals but may also offer valuable incentives for physicians to start their professional career in inpatient rheumatology.

[Partial k-space sampling with zero filling used with phase-contrast flow measurements: in vivo and in vitro validation]. / Partielle k-Raum-Auslesung mit Null-Interpolation bei Phasenkontrast-Flussmessungen: In-vivo- und In-vitro-Validierung.

PURPOSE: To validate the technique of partial k-space sampling and zero filling with phase-contrast flow measurements as compared to measurements with full k-space sampling. MATERIALS AND METHODS: In vitro: A laminar flow phantom was utilized to evaluate the effect of partial k-space sampling on the accuracy, precision and signal-to-noise ratio of phase-contrast flow measurements. In vivo: The effect of partial k-space sampling on the quantification of cardiac output (n = 40 patients) and the duration of the scan were evaluated in the ascending aorta (n = 37) and pulmonary trunk (n = 34) in a prospective study. RESULTS: Partial k-space sampling resulted in an increase in the SNR by 2 % in vitro. The precision was altered by less than 1 %. Flow volumes were systematically overestimated by 3.5 %. No significant differences were found in the in vivo measurements of cardiac output. The scan duration was reduced by 34 % by utilizing partial k-space sampling. CONCLUSION: Partial k-space sampling can be used to reduce scan time without a significant decrease in the accuracy or precision of phase-contrast flow measurements in large arteries.
