Computer-aided design files were generated for a size 18 French catheter prototype with a compartment for vitamin D solution to be manually introduced into the catheter's lumen and sealed via thermoplastic welding. Polylactic acid (PLA) bioplastic was 3D printed into filaments via material extrusion (FDM^®, Stratasys, Eden Prairie, MN) on a 5th generation Replicator 3D printer (MakerBot). Three different forms of vitamin D were used, cholecalciferol, ergocalciferol, and calcitriol, and 0.9% normal saline served as a control. Three prints of each catheter type were fabricated and scanned using a 1.5 T MR whole body scanner (Avanto, Siemens Healthcare) inside a small flex loop surface radiofrequency (RF) coil. A 3D gradient recalled echo (GRE) sequence was used with the following acquisition parameters: 4.52/11 ms TE/TR, 15° flip angle, 256 × 256 matrix with 0.5 mm × 0.5 mm in-plane resolution, 24 coronal slabs, 2 mm thickness, and 140 Hz receiver bandwidth.
