Autor: Filiz, Osmanodja, Julie, Rösch, Michael, Knott, Arnd, Doerfler, David, Grodzki, Michael, Uder, Rafael, Heiss

Publikováno v: Investigative Radiology. 58:121-125

Intracranial aneurysm (IA) is the main cause of subarachnoid hemorrhages. Time-of-flight (TOF) magnetic resonance angiography (MRA) at 1.5 T or 3 T magnetic resonance imaging (MRI) is a well-established method for the diagnosis of IA. The aim of this

Modern Low-Field MRI of the Musculoskeletal System: Practice Considerations, Opportunities, and Challenges

Autor: Iman Khodarahmi, Mahesh B. Keerthivasan, Inge M. Brinkmann, David Grodzki, Jan Fritz

Publikováno v: Investigative radiology. 58(1)

Magnetic resonance imaging (MRI) provides essential information for diagnosing and treating musculoskeletal disorders. Although most musculoskeletal MRI examinations are performed at 1.5 and 3.0 T, modern low-field MRI systems offer new opportunities

Opportunities in Interventional and Diagnostic Imaging by Using High-Performance Low-Field-Strength MRI

Publikováno v: Radiology. 293:384-393

Background Commercial low-field-strength MRI systems are generally not equipped with state-of-the-art MRI hardware, and are not suitable for demanding imaging techniques. An MRI system was developed that combines low field strength (0.55 T) with high
