Hybrid PET/CT (Siemens LSO Biograph 2, Siemens Medical Solutions, USA) of the hip area. Shown are transverse slices of CT (a), uncorrected PET (b) and attenuation-corrected PET (c). The hip prosthetic results in severe artefacts on CT, which subsequently results in a seemingly high uptake on the corrected PET (white arrows), not present on the uncorrected PET. The PET hot-spot at the far right side of the patient (blue arrow) is a true-positive (bursitis).
