MRI in breast care
MR imaging in breast care can help provide early and reliable diagnosis especially in difficult cases. It can support accurate preoperative staging and differential diagnosis, resulting in faster and more cost-effective patient management. Extremely high spatial and temporal resolution can be achieved in very short acquisition times by using iPAT with GRAPPA and CAIPIRINHA.
From patient comfort to coils, protocols, and tips and tricks e.g., when imaging patients with implants – get the latest updates on MR Mammography in this whitepaper.
Whitepaper on MRI acceleration
By pioneering innovations such as Compressed Sensing, Simultaneous Multi-Slice and CAIPIRINHA Siemens has the most comprehensive portfolio of MRI acceleration techniques.
These methods can be used to significantly accelerate image acquisition, to increase robustness toward motion and physiological process and ultimately to expand the patient population eligible for MRI. In this whitepaper we share our view on the advantages and weaknesses of the different methods for certain clinical questions and give an outlook into the future.
Definitions of RF receiver channels and coil density
The number of RF receiver channels is one of the key purchasing criteria. Multi-channel RF systems offer clear clinical benefits with regard to coverage, image quality, and speed. We have defined meaningful and relevant definitions for the terms “RF channels” and “coil density” that are clearly related to clinical benefits. This standard should help to achieve a better comparability of RF systems and coils across different vendors.
Magnet Homogeneity and Shimming
The magnet is the most prominent – and most expensive – part of an MRI system. There are several features and specifications of the magnet design that have an influence on different criteria: Image quality, patient comfort, and economic aspects. In this Whitepaper, the aspects of magnet homogeneity, shimming capabilities, and their respective relevance for MRI will be addressed.
Gradient Performance and Gradient Amplifier Power
Gradient performance is more than the maximum amplitude (strength) and the maximum slew rate (speed). There are numerous design criteria for a gradient coil to be considered. In addition, there is the gradient power amplifier (GPA) that ‘drives’ the gradient coil. This paper discusses the key characteristics of the gradient coil as well as the gradient amplifier, with their inter-dependencies and their clinical benefits.
New Strategies for Prostate Ca Management
The advancement in MRI enables a transition from whole prostate treatment to a targeted one based on clinical significance and aiming to preserve healthy tissue and patients quality of life. In this whitepaper, international experts provide you with a state-of-the-art account of where we are in this process of transition.
Compliance with EMF Directive EU 2013 / 35 / EU
This flyer discusses the application of the EU Directive 2013 / 35 / EU regarding the occupational exposure to electromagnetic fields with respect to magnetic resonance equipment. It is intended to help organizations operating MRI systems to comply with the requirements of the Directive.
