Peripheral Neuropathies of the Median, Radial, and Ulnar Nerves: MR Imaging Features
TL;DR: MR imaging may help establish the cause of the condition and provide information crucial for conservative management or surgical planning and knowledge of the normal anatomy and of the possible causes, typical clinical findings, and MR imaging features of peripheral neuropathies that affect the median, radial, and ulnar nerves allows greater confidence in the diagnosis.
Journal ArticleDOI
MR neurography: past, present, and future.
Avneesh Chhabra,Gustav Andreisek,Theodoros Soldatos,Kenneth C. Wang,Aaron J. Flammang,Allan J. Belzberg,John A. Carrino +6 more
TL;DR: The historic perspective of MRN, the current imaging trends of this modality, and the future directions and applications that have shown potential for improved imaging and diagnostic capabilities are reviewed.
Journal ArticleDOI
Metallic artefact reduction with monoenergetic dual-energy CT: systematic ex vivo evaluation of posterior spinal fusion implants from various vendors and different spine levels.
Roman Guggenberger,Sebastian Winklhofer,Georg Osterhoff,Guido A. Wanner,M. Fortunati,Gustav Andreisek,Hatem Alkadhi,Paul Stolzmann +7 more
TL;DR: Monoenergetic DECT provides significantly better image quality and less metallic artefacts from implants than SECT and CT images are interpreted better with monoenergetic extrapolation using dual-energy (DE) CT.
Journal ArticleDOI
Quantification of Muscle Fat in Patients with Low Back Pain: Comparison of Multi-Echo MR Imaging with Single-Voxel MR Spectroscopy
Michael A. Fischer,Daniel Nanz,Ann Shimakawa,Timo Schirmer,Roman Guggenberger,Avneesh Chhabra,John A. Carrino,Gustav Andreisek +7 more
TL;DR: Large-volume image-based (dual-echo and multi-echo MR imaging) and spectroscopic fat-signal fractions agree well, thus allowing fast and accurate quantification of muscle fat content in patients with low back pain.
Journal ArticleDOI
Anatomic MR Imaging and Functional Diffusion Tensor Imaging of Peripheral Nerve Tumors and Tumorlike Conditions
Avneesh Chhabra,Rashmi S. Thakkar,Gustav Andreisek,Majid Chalian,Allan J. Belzberg,Jaishri O. Blakeley,Ahmet Hoke,Gaurav K. Thawait,John Eng,John A. Carrino +9 more
TL;DR: 3T MR imaging and DTI are valuable methods for anatomic and functional evaluation of peripheral nerve lesions with excellent interobserver reliability, and tractography and low FA provide insight into neural integrity while low diffusivity values indicate malignancy in neural masses.
