Evaluation of 7 Tesla pTx Body Coils Regarding Transmit and Receive Performance.

PURPOSE Most sites develop and use custom coils for 7 T body MRI since no standard pTx body coil exists, leading to diverse coil designs differing in transmit element type, layout, and number of receive channels. This study investigates and compares eight existing coils, including one remote body coil array and seven l...

Time-Efficient Interleaved Spin Density-Weighted and Inversion Recovery 23Na MRI of the Human Calf Muscle at 7 T.

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.

Quantification of the Tissue Sodium Concentration in the Human Calf at 7T With Reduced Acquisition Time: Influence of the Nominal Spatial Resolution

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...
