If so, which one of the two sounds better to use?
(1) Anatomical imaging includes techniques that allow us to view the internal body structures on a digital image i.e. X-rays, CT scans, MRI scans, PET scans, etc. AND these structures might well be normal.
(2) Pathological anatomy is the actual physical structure of body organs and tissues in disease. This deranged anatomy might be described as gross anatomy [what might be seen at post mortem for example or during surgery], or in the same imaging technique in (1) above, or as abnormal microscopic or haematological changes seen in histology sections.
Hope this helps!
