Diagnostic imaging of lung disorders is of high clinical relevance. MRI of the lung constitutes a challenge [1], due to low proton density. Consequently, lung ventilation is commonly visualized using hyperpolarized noble gases [2], sulphur hexafluoride (SF₆) [3] or other exogenous agents. ¹⁹F-containing gasses presents a valuable alternative. In recognizing of this opportunity, this study proposes an eight channel ¹⁹F/¹H transceiver array tailored for lung imaging at 7.0 T using a pTX-Array. The feasibility of the proposed RF coil array for ¹⁹F/¹H-MRI is demonstrated in phantom experiments and in in vivo studies.The RF coil consists of a planar posterior (Fig1. A) and an anterior (Fig1. B) section which is modestly curved to conform to an average chest. Each section contains 2 loops and two dipoles optimized for ¹⁹F (f=279 MHz, element size 300 x 50 mm²) and a RF-shield (Fig1 C). EMF-simulations were performed using CST Studio Suite 2014 (CST AG, Darmstadt, Germany) with a phantom (Fig 3 A), voxel model Duke (Fig. 2) and Ella (Virtual family, IT’IS Foundation, Zurich, Switzerland). B¹₊-shimming using simulated data was performed to improve the transmission field homogeneity at minimum SAR within a VOI covering the lung (Fig. 2). Local SAR averaged over 10g of tissue was calculated and the input power was adjusted to meet the limits of IEC 60601-2-33 Ed.3. This procedure was applied for the ¹⁹F- and ¹H-frequency. Measurements were performed on a torso phantom containing Agarose-gel+NaCl and a cylindrical insert containing Galden (Apollo Scientific Ltd., Denton, Manchester, UK), a Perfluoropolyether, using a 7 T whole body MRI system with an 8-channel pTX-Array (Magnetom, Siemens, Erlangen, Germany). Two different phase settings where employed- phaseset 0: same phase setting for all channels, phaseset 1: phase setting deduced from EMF simulation of the human voxel models Duke and Ella. To validate the simulation a Bloch-Siegert B1-mapping technique was utilized[4] (Fig.3 B). ¹H-MRI: 2D-FLASH, TR/TE=100/3.3ms, FA=20°, resolution=(0.78x0.78x5)mm3, avg=1 (Fig. 3 C). ¹⁹F-MRI: 2D-FLASH, TR/TE=20/3ms,FA=20°, resolution=(1.95x1.95x5)mm3, avg=32 (Fig. 3 D). Whole VOI coverage ¹⁹F 3D datasets were acquired with a density-adapted 3D radial acquisition technique [5]: TE=0.4 ms, TR=11 ms, TRO=7.1 ms, TX amplitude 115 V (~90% SAR) equivalent to a tip angle of 30-40°, number of projections=50000, averages=2, voxel size=(1.95x1.95x1.95) mm³, scantime = 18:20min (Fig. 4). In-vivo cardiac ¹H imaging was performed using 2D CINE FLASH: matrix 256x256, TE=1.84 ms, TR=4.14 ms, voxel size (1.4x1.4x4.0) mm³, cardiac phases=30, total acquisition time=0:16 min. An MR stethoscope (EasyACT, MRI.TOOLS GmbH, Berlin, Germany) was employed for cardiac gating [6]The reflection coefficients of the eight channels were less than -20dB@279MHz and less than -7dB@297MHz. The coupling between the channels was less than -12dB@279MHz and less than -20dB@297MHz. Maximum local SAR10g did not exceed the limits of 20 W/kg for an input power of 34 W for 279MHz and 297MHz. Whole body and partial body SAR were well below the IEC limits. The combination of independent loops and dipole-elements was of advantage for decoupling reasons. The outer loop-elements could be easier tuned and matched to the human body. The inner dipoles provided higher depth-penetration, which was instrumental to cover the entire VOI. B₁⁺ mapping confirmed the transmission fields deduced from EMF simulations (Fig. 3+4). To demonstrate the in-vivo B₁⁺ uniformity of the array for deep lying organs in the torso, cardiac and renal MR was conducted at 297 MHz (Fig. 5).This work demonstrates the feasibility of an eight channel transceiver array tailored for ¹⁹F lung MRI. Our results show that the array can be also used for ¹H imaging, therfore supports anatomical ¹H imaging as well as functional ¹⁹F MRI of the lung in clinically acceptable scan times. The proposed eight channel ¹H/¹⁹F transceiver RF coil array contributes to the technological basis for the clinical assessment of lung ventilation and pulmonary inflammation but also to research into the bio distribution and bioavailability of ¹⁹F-containing drugs. The results underscore the challenges of fluorine MR in humans and demonstrate that these issues can be offset by using tailored RF coil hardware. The benefits of such improvements would be in positive alignment with the technological requirements of further studies, that are designed to examine the potential of ¹⁹F MR to trace and quantify ¹⁹F-containing agents and drugs.
