Especially in pediatric radiology locating foreign
objects with CT is not desirable due to ionising
radiation. A radial 3D ultra short echotime (UTE)
sequence with 0.66mm isotropic resolution, both with and
without the use of a long T2 tissue suppression pulse,
was evaluated for wooden and glass foreign objects in a
phantom (pig feet). Especially the UTE sequence with
long T2 suppression seems ideal as a search modality for
wood due to the excellent contrast while CT images
provide very poor contrast for biological material. In
the case of glass, CT image quality is cleary superior,
but the UTE sequence should still be able to provide the
exact location of a glass splinter in most cases.
