Abstract
Thirtyfive patients with LVV diagnosed according to the current standard of reference and 35 controls were imaged at 30T using 12 × 13 × 20 mm3 fatsuppressed T1w3D modified Volumetric Isotropic TSE Acquisition mVISTA pre and postcontrast Applying a navigator and peripheral pulse unit triggering PPU the total scan time was 10–12 min Thoracic aorta and subclavian and pulmonary arteries were evaluated for image quality IQ flow artefact intensity diagnostic confidence concentric wall thickening and contrast enhancement CWT CCE using a 4point scaleIQ was good in all examinations 325 ± 072 and good to excellent in 342 of 408 evaluated segments 838 while 841 showed no or minor flow artefacts The interobserver reproducibility for the identification of CCE and CWT was 0969 and 0971 p 0001 with an average diagnostic confidence of 347 ± 064 CCE and CWT were strongly correlated Cohen’s k = 087 P 0001 and significantly more frequent in the LVVgroup 528 vs 10 598 vs 24 P 0001
