Institute of Radiology, University Hospital Erlangen, Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), Erlangen, Germany.
Purpose: CEST MRI is influenced by fat signal, which can reduce the apparent CEST contrast or lead to pseudo-CEST effects. Our goal was to develop a fat artifact correction based on multi-echo fat-water separation that functions stably for 7 T knee MRI data.
Methods: Our proposed algorithm utilizes the full complex data and a phase demodulation with an off-resonance map estimation based on the Z-spectra prior to fat-water separation to achieve stable fat artifact correction.
Pseudo-tendinopathy on MRI of the navicular and tarsometatarsal parts of the tibialis posterior tendon: A study in normal individuals.

Department of Radiology, Universitair Ziekenhuis Brussel, Brussel, Belgium. Electronic address:
Purpose: To determine the normal thickness and MRI appearance of the Tibialis Posterior Tendon near the navicular insertion in normal volunteers.
Materials And Methods: By using a 3T MRI system 41 ankles were imaged, and PD weighted images with fat saturation were acquired in the three orthogonal planes. Symptoms of tendon pathology and history of trauma or surgery of the tendon were used as volunteer exclusion criteria.
Pseudo-tear appearance of the Achilles tendon on MR imaging in normal volunteers.

Department of Radiology, UZ Brussel, Laarbeeklaan 101, 1090, Jette, Brussels, Belgium.
Purpose: The aim of this study was to confirm our clinical observation that a pseudo-tear appearance of the Achilles tendon is commonly seen on MRI and is of no clinical relevance.
Materials And Methods: Forty-one ankles were imaged on a 3 T MR system, and PD weighted images with fat saturation were obtained in three orthogonal planes (TR, 2969 ms; TE, 30 ms; NA, 2; slice thickness, 2.5 mm).

Department of Radiology, UZ Brussel, Laarbeeklaan 101, 1090, Brussels, Belgium.
Purpose: This study aimed at studying the MR imaging appearance of the tibiotalar ligament in asymptomatic volunteers.
Materials And Methods: Fourty-two ankles were imaged on a 3T MR system using proton density weighted images with fat saturation (TR, 2969 ms; TE 30 ms; NA, 2; slice thickness, 2.5 mm).
