# PET with accompanying CT

419 PET slices spanning 847 mm, plus 161 CT slices spanning 160 mm. Both source imaging series are complete as indexed by IDC, but the accompanying CT covers only part of the PET field. Shared DICOM coordinates support linked comparison within the overlap; this is not newly computed registration. Original DICOM bytes are unchanged. Values are source activity concentration in Bq/mL, not calculated SUV. Ancillary SEG/SR annotations are not included.
