C's Flashcards
central beam
X-ray photons in the middle of the x-ray beam.
cervical spondylopathy
Refers to deformity of vertebral bodies, narrowing of the vertebral canal, vertebral instability, and/or malarticulation with varying degrees of spinal cord compression in the neck.
cholangiography
A radiographic contrast study of the bile ducts.
cholecystocholangiography
A radiographic contrast study of the gall bladder and bile ducts.
cholelith
A concretion in the gall bladder
choledocolith
A concretion in a bile duct
chondrodysplasia
Inherited deformities of the bony skeleton caused by abnormal cartilage development. Affected animals are characterized by a normal-sized trunk with abnormally shortened limbs.
chondrodystrophic
Refers to an animal exhibiting chondrodysplasia (e.g., Dachshund, Bassett Hound). Term often is used interchangeably with achondrodysplastic
chondroma
A benign, slow-growing tumor of cartilage, more often occurring in flat bones (e.g., scapula, pelvis, ribs) and appearing as a well-defined, expansile mass that is less opaque than surrounding bone. A chondroma may contain mineralized components.
chylothorax
Accumulation of chyle in the pleural space, often secondary to rupture of the thoracic duct.
chylous effusion
Accumulation of chylous fluid in the pleural space, may be associated with heart failure, mediastinal neoplasia, or mediastinitis.
cineradiography (cineflurography)
The making of a video record directly from a fluorescent screen (i.e., recording of real-time radiographic imaging.)
clock face analogy
Technique used to approximate the locations of cardiac chambers by mentally superimposing the numbers of a clock face over the cardiac silhouette on alateral or ventrodorsal/dorsoventral thoracic radiograph

Codman’s triangle
Occurs when aggressive soft tissue opacity material wedges between a mineralized periosteal response and the underlying cortex. The periosteal response may appear solid, well-defined, and homogeneous in this area, giving the erroneous appearance of a benign, inactive lesion (which is not the true nature of the disease process). Codman’s triangle develops at the periphery of a rapidly growing disease process, usually on the diaphyseal side.during exposure to blur the grid lines. Modern grid lines are very thin and only faintly visible; therefore, a Bucky may not be necessary with modern equipment.
calcification
The normal or abnormal deposition of calcium salts in soft tissues.
calcinosis
Abnormal deposition of calcium salts in various
tissues.
- calcinosis cutis: Calcium deposits in the skin, often secondary to hypercorticosterism.
- calcinosis circumscripta (tumoral calcinosis): Deposits of
calcium in subcutaneous, tendinous, ligamentous, or muscular
tissues as firm, well-circumscribed, tumorlike nodules; typically occurring on limbs, over bony prominences, and under foot pads.
calvarium
The upper, domelike part of the skull, formed by the frontal, parietal, and occipital bones; the encasement for the brain.
cancellous bone
The trabeculated, spongy, or porous bone found in ends of long bones, in vertebrae, and in flat bones.
canine leukocyte adhesion disorder (CLAD)
Rare inherited condition of abnormal granulocytes resulting in mandibular periosteal response and metaphyseal flaring.
carcinomatosis
Widespread distribution of neoplasia throughout a body cavity; commonly used to describe diffuse implantation of tumor nodules within the peritoneal space (e.g., pancreatic carcinoma).
cardiac silhouette
Outline of the pericardial sac and its contents as seen on a thoracic radiograph.
cartilage joint
Two or more bones united by hyaline cartilage or fibrocartilage (e.g., costochondral junctions, pelvic symphysis).
cassette
A light-tight, semirigid container used to house and protect x-ray film and screens or a phosphor-coated imaging plate during exposure and transport to processing
cathode
The negative terminal in the x-ray tube. Cathode (filament) emits electrons, which are attracted to the anode (positive terminal). Current flows from cathode to anode. In x-ray tubes, the cathode commonly consists of a helical tungsten filament, behind which is a molybdenum reflector cup used to focus the electron emission toward the anode target.
