- What is a ventrodorsal (VD) radiographic view?
- 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?
- 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?
- A view at an angle between lateral and VD, typically at 45 degrees.
- Which radiographic view shows the left side of the thorax?
- Left lateral view, where the left side is closest to the table.
- What is collimation in radiography?
- 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?
- 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?
- 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?
- The animal is positioned on its back in dorsal recumbency with limbs extended naturally.
- What is the centering point for a pelvic radiograph?
- The caudal aspect of L7 vertebra or the cranial aspect of S1 vertebra, midline.
- What is the centering point for a thoracic radiograph?
- The mid-thorax at approximately T5 or T6 vertebra, midline.
- What does mAs (milliamperage-seconds) control in radiography?
- The quantity of X-rays produced, affecting the overall darkness or exposure of the radiograph.
- What does kVp (kilovoltage peak) control in radiography?
- 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?
- Exposure decreases following the inverse square law; doubling distance requires four times the exposure.
- What is barium sulfate used for in radiography?
- A positive contrast agent used to outline gastrointestinal structures for visualization.
- What is iodine contrast used for in radiography?
- A positive contrast agent for myelography, angiography, and urography to visualize vasculature and neural structures.
