Radiology Views Flashcards
What does the name of a radiologic view indicate?
Indicates the direction of travel of the x-ray beam
Caudal-Cranial View
Dog on its back, belly up
Cranial-Caudal View
Dorso65Proximal-PalmaroDistal Oblique (65 DP) Equine
Dorsopalmar View (Equine)
Palmar-Proximal-Palmar-Distal Oblique (Flexor Navicular View)
DLPMO View
DMPLO View
Rostrocaudal (Frontal Sinus) View
How should the spine be positioned in relationship to the tabletop?
Should be parallel to the table top
Positioning for Lateral View
Foam support wedges or sandbags may be needed under the neck. Retract thoracic limbs to optimize looking at the caudal cervical spine (decreases tissue thickness)
Positioning for Ventrodorsal View
Foam wedges or sandbags may be necessary. Spinous processes should be midline. (seen only as oval mineral opacities superimposed with the vertebral bodies)
How do you position barrel or deep-chested dogs for a thoracic spine: lateral view?
It is difficult to get the spine parallel to table. Can put a wedge under sternum.
Positioning for Dorsoventral
Dog is on its stomach, radiation goes through back to stomach
Where can osteochondrosis form?
Can form anywhere you have articular cartilage or articular surface
What is Osteochondrosis?
Dysfunction of endochondral ossification. Cartilage cells do not make the transition into bone but continue to proliferate. (gets stuck in cartilage zone and never converts to bone)
What is the hallmark of osteochondrosis?
Defect of the thickened area of cartilage or erosion. May also represent subchondral erosion.
Osteochondritis Dissecans
A calcified flap of articular cartilage and mineral fragments are seen. The thickened area may become displaced, if there is no joint effusion, there are no nutrients going to the cartilage so cartilage can die and fall off and may become mineralized.
