OBJECTIVE
While most sodium (23Na) MRI studies focus on apparent tissue sodium concentration (aTSC), longitudinal (T₁) and transverse (T₂*) relaxation times may provide additional microstructural and physiological information. This study aimed to establish reference values for 23Na T₁ and bi-exponential T₂* in human lo...

Accurate knowledge of perforator vessels is crucial for successful perforator flap surgery. The purpose of this prospective, single-center study was to compare three imaging modalities, color-coded duplex sonography (CCDS), flat-panel computed tomography (FPCT) and non-contrast time-of-flight magnetic resonance angiogr...

The proposed interleaved sequence enables simultaneous acquisition of 23Na SDW and IR contrasts, thereby reducing overall scan time and eliminating the need for co-registration.

To evaluate the repeatability and consistency of rapid quantitative 23Na MRI of the human calf, an acquisition‐weighted stack‐of‐stars (AW‐SOSt) sequence was implemented on a 7T MRI system and used for all measurements. Three variants, differing only in nominal in‐plane spatial resolution (2.5, 5.0, and 7.5 mm) and cor...
