Question

Given below are two statements:
Statement I: When the animal is lying on its left side it is known as supine position.
Statement II: Dog is kept in supine position to take ventro-dorsal radiograph of abdomen.
In light of the above statements, choose the correct answer from the options given below.

• A. Both Statement I and Statement II are true.
• B. Both Statement I and Statement II are false.
• C. Statement I is true but Statement II is false.
• D. Statement I is false but Statement II is true.

Hint:

Remember the directional terms in radiology:
- Supine = Dorsal recumbency (lying on back, belly up) $\rightarrow$ Used for Ventro-Dorsal (VD) views.
- Prone = Sternal recumbency (lying on chest, back up) $\rightarrow$ Used for Dorso-Ventral (DV) views.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Patient positioning in veterinary radiology is critical to obtaining diagnostic-quality radiographs.
Terms like "recumbency" describe which side of the body the animal is resting on, while directional terms describe the path of the x-ray beam.

Step 2: Detailed Explanation:
Let us analyze each statement:
- Statement I: When an animal is lying on its left side, it is in left lateral recumbency.
The "supine position" (or dorsal recumbency) refers to the animal lying on its back, with the ventral surface facing upwards.
Thus, Statement I is false.
- Statement II: To obtain a ventro-dorsal (VD) radiograph of the abdomen, the x-ray beam must enter the ventral surface of the abdomen and exit through the dorsal back.
To achieve this, the animal must be placed on its back in dorsal recumbency (supine position).
Thus, Statement II is true.

Step 3: Final Answer:
Since Statement I is false and Statement II is true, the correct option is (D).
