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.
