The question involves identifying the appropriate dye used in the diagnosis of esophageal perforation. The correct answer is Barium sulphate. Here's the explanation:
1. In radiodiagnosis, contrast agents are crucial for enhancing the visibility of internal structures in imaging studies.
2. For esophageal perforations, it is essential to use a contrast agent that provides clear imaging while minimizing risk.
3. Barium sulphate is a commonly used contrast agent in radiology, particularly for evaluating the gastrointestinal tract, due to its high atomic number, which provides excellent contrast on X-rays.
4. It's important to note that Barium sulphate is often preferred in non-acute scenarios of esophageal evaluation despite the risk of leakage into the mediastinum if there is a large perforation, which could potentially lead to complications.
Option
Usage
Iohexol
Often used in CT imaging as an intravenous contrast.
Barium sulphate
Preferred for gastrointestinal tract imaging, including esophagus.
Gadolinium
Primarily used in MRI as a contrast agent.
Iodine dye
Commonly used in X-rays and CT scans for vascular imaging.
In conclusion, Barium sulphate is the dye of choice for diagnosing esophageal perforations, providing reliable imaging in the radiodiagnostic process.
