A 10-year-old female patient with rhabdomyosarcoma. An oval-shaped pulmonary nodule with a maximum axial diameter of 7 mm (axial average diameter of 5 mm) was detected on chest CT in the left upper lobe (a). The nodule was not detected with the incoherent GRE sequence (b) and the volume interpolated GRE sequence (c) in the initial blinded session, as the nodule was misinterpreted as part of a vessel due to its linear appearance (circles); furthermore, the lesion was only shown in one image in both GRE sequences due to the slice thicknesses of 4 mm. The oval-shaped nodule (circle) was detected in the UTE image (d) in the initial evaluation session; the lesion was additionally seen in 3 images because of the slice thickness of 1.2 mm of the UTE sequence
