Journal ArticleDOI
Age- and Level-Dependence of Fatty Infiltration in Lumbar Paravertebral Muscles of Healthy Volunteers.
Rebecca J. Crawford,Rebecca J. Crawford,Lukas Filli,James M. Elliott,James M. Elliott,James M. Elliott,Daniel Nanz,Michael A. Fischer,Magda Marcon,Erika J. Ulbrich +9 more
TL;DR: Lumbar paravertebral muscle fat content increases with aging, independent of volume, in healthy volunteers 20–62 years of age.
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
Quantification of liver fat in the presence of iron and iodine: an ex-vivo dual-energy CT study.
Michael A. Fischer,Ralph Gnannt,Dimitri A. Raptis,Caecilia S. Reiner,Pierre-Alain Clavien,Bernhard Schmidt,Sebastian Leschka,Hatem Alkadhi,Robert Goetti +8 more
TL;DR: DECT with the use of a dedicated, iron-specific 3-material decomposition algorithm allows for the accurate quantification of LFC, even in the presence of iron and iodinated CM, according to an ex vivo phantom study.
Journal ArticleDOI
MRI: the new reference standard in quantifying hepatic steatosis?
Dimitri A. Raptis,Michael A. Fischer,Rolf Graf,Daniel Nanz,Achim Weber,Wolfgang Moritz,Yinghua Tian,Christian E. Oberkofler,Pierre-Alain Clavien +8 more
TL;DR: There was a significant correlation of the MRI fat quantification with several parameters of liver injury, and MRI data could predict mouse survival after ischaemia/reperfusion injury and MRI can predict intrahepatic fat with high accuracy.
Journal ArticleDOI
Dixon-based MRI for assessment of muscle-fat content in phantoms, healthy volunteers and patients with achillodynia: comparison to visual assessment of calf muscle quality
Michael A. Fischer,Christian W. A. Pfirrmann,Norman Espinosa,Dimitri A. Raptis,Florian M. Buck +4 more
TL;DR: Two-point Dixon-based MRI allows for accurate quantification of MFC, outperforming visual assessment of calf muscle fat and structural damage of the Achilles tendon is associated with a significantly higher MFC.
