Fig 6a: High resolution (HR) computed tomography scan of
the third metacarpal bone using volume modulated arc technique. Palmar
view of delineation of the gross tumor volume (pink zone), clinical
target volume (orange zone) and the planning target volume (outer double
lines). Fig 6b: Palmar view of the third metacarpal bone on a HR CT
scan. Fig 6c: Positioning of the left forelimb in a vacuum cushion. Line
marks were added for initial positioning.
Fig 7: Dorsopalmar (A and B) and dorsomedial –
palmarolateral oblique (C and D) views of the third metacarpal bone six
months (A and C) and eighteen months (B and D) after radiation
therapy . The periosteal reaction of the second and third
metacarpal bone has become smoother and the lesion has partially filled
up during follow-up radiographs over the next eighteen months.
