Zusammenfassung
AbstractIn the context of hybrid imaging using SPECT/CT and PET/CT, CT is usually performed as a non-diagnostic low-dose examination (so-called auxiliary CT). In this case, the CT data are used for attenuation correction and offer the possibility of an anatomical correlation of nuclear medicine findings. As a radiation application, this form of CT is also subject to the general optimization rule. Depending on the application scenario, various key aspects must be taken into account. Examples include the potential influence of CT reconstruction on the attenuation correction of emission data, the detectability of a…
