Ultra-low-dose CT for attenuation correction: dose savings and effect on PET quantification for protocols with and without tin filter

Ultra-low-dose (ULD) computed tomography (CT) scans should be used when CT is performed only for attenuation correction (AC) of positron emission tomography (PET) data. A tin filter can be used in addition to ...
