- What is a ventrodorsal (VD) radiographic view?
Show answer
An anteroposterior view taken from the ventral (belly) side with the X-ray beam passing through to the dorsal (back) surface.- What is a lateral radiographic view?
Show answer
A side-to-side view where the X-ray beam passes through from one lateral side to the other.- What is an oblique radiographic view?
Show answer
A view at an angle between lateral and VD, typically at 45 degrees.- Which radiographic view shows the left side of the thorax?
Show answer
Left lateral view, where the left side is closest to the table.- What is collimation in radiography?
Show answer
The restriction of the X-ray beam to the area of interest using a collimator to reduce scatter radiation.- When is a grid used in radiography?
Show answer
When increased penetration of tissue is needed to reduce scatter radiation and improve image contrast, typically for thicker body parts.- What is the proper patient positioning for a thoracic radiograph, lateral view?
Show answer
The animal is positioned in lateral recumbency with forelimbs pulled cranially and hindlimbs pulled caudally.- What is the proper patient positioning for an abdominal radiograph, VD view?
Show answer
The animal is positioned on its back in dorsal recumbency with limbs extended naturally.- What is the centering point for a pelvic radiograph?
Show answer
The caudal aspect of L7 vertebra or the cranial aspect of S1 vertebra, midline.- What is the centering point for a thoracic radiograph?
Show answer
The mid-thorax at approximately T5 or T6 vertebra, midline.- What does mAs (milliamperage-seconds) control in radiography?
Show answer
The quantity of X-rays produced, affecting the overall darkness or exposure of the radiograph.- What does kVp (kilovoltage peak) control in radiography?
Show answer
The quality and penetrating power of the X-ray beam; higher kVp increases penetration.- How does increasing distance from the X-ray tube affect exposure in radiography?
Show answer
Exposure decreases following the inverse square law; doubling distance requires four times the exposure.- What is barium sulfate used for in radiography?
Show answer
A positive contrast agent used to outline gastrointestinal structures for visualization.- What is iodine contrast used for in radiography?
Show answer
A positive contrast agent for myelography, angiography, and urography to visualize vasculature and neural structures.
