Non-Enhanced MR Imaging of Cerebral Aneurysms: 7 Tesla versus 1.5 Tesla
PURPOSE To prospectively evaluate 7 Tesla time-of-flight (TOF) magnetic resonance angiography (MRA) in comparison to 1.5 Tesla TOF MRA and 7 Tesla non-contrast enhanced magnetization-prepared rapid acquisition gradient-echo (MPRAGE) for delineation of unruptured intracranial aneurysms (UIA). MATERIAL AND METHODS Sixteen neurosurgical patients (male n = 5, female n = 11) with single or multipl...
متن کاملNon-Enhanced T1-Weighted Liver Vessel Imaging at 7 Tesla
OBJECTIVES Aim of the study was to assess the feasibility and to compare three non-enhanced T1-weighted (w) sequences for liver vessel imaging at 7 Tesla (T). MATERIAL AND METHODS 12 healthy volunteers were examined on a 7 T whole-body MR-system. The following non-enhanced sequences were acquired: T1w 2D FLASH, T1w 3D FLASH and Time of flight (TOF)-MRA. Qualitative image analysis was performe...
متن کامل7 Tesla MR Imaging : Opportunities and Challenges MRT bei 7 Tesla : Möglichkeiten und Herausforderungen
After the introduction of the first 8 Tesla magnet at the Ohio State University in the late 1990s, there has been a continuously increasing number of ultra-high-field (> 7Tesla) unit installations worldwide (approximately 40 to date) [1–5]. The urge to increase magnetic field strength is driven by a number of associated changes of physical features. These changes may entail positive as well as ...
متن کاملClinical Multiparametric MR Imaging of Breast Tumors at 7 Tesla
Magnetic Resonance Imaging (MRI) of the breast is a powerful imaging tool for the characterization, diagnosis, staging, and treatment monitoring of breast cancer. Applications at clinical magnetic field strengths (≤ 3T) have been extensively described. At 7T*, substantial improvements in image quality could be provided, if technical challenges can be overcome. In this article, the authors discu...
متن کاملGadolinium Enhanced MR Coronary Vessel Wall Imaging at 3.0 Tesla
Purpose. We evaluated the influence of the time between low-dose gadolinium (Gd) contrast administration and coronary vessel wall enhancement (LGE) detected by 3T magnetic resonance imaging (MRI) in healthy subjects and patients with coronary artery disease (CAD). Materials and Methods. Four healthy subjects (4 men, mean age 29 ± 3 years and eleven CAD patients (6 women, mean age 61 ± 10 years)...
