Respiratory problems in pets can vary from simple cases to complex and dangerous conditions. Veterinarians use various tools for the accurate diagnosis of these issues and to provide appropriate treatment, one of the most important of which is radiography. This article examines the process of referring patients with respiratory problems for radiology and discusses the role of chest and head radiography in diagnosing radiological patterns related to respiratory problems in pets respiratory problems in pets. 
Referring Respiratory Problems to Radiology for Diagnosis
When a pet with respiratory problems is referred to a veterinarian, one of the first steps is to refer for radiology for chest radiography of the pet. This procedure helps the veterinarian to examine lung patterns and determine what is happening in the lungs and the cause of the respiratory problems.
Examining Lung Patterns
Chest radiography can indicate the presence of fluid, masses, or infection in the lungs. However, sometimes the lungs appear healthy and do not respond to treatment, or after some time, respiratory problems return. In such cases, it is necessary to also examine the upper respiratory system.
Upper and Lower Respiratory Systems
The respiratory system is divided into upper and lower parts. The lower respiratory system includes the lungs, but the upper respiratory system includes the nose, nasal passages, sinuses, pharynx, and trachea. Sometimes respiratory problems occur due to issues in the upper respiratory system. 
Examining the Upper Respiratory System of Pets with Radiography
To examine the upper respiratory system, radiography of the head and neck is performed. This examination helps the veterinarian identify problems such as swelling, fluid accumulation, or masses.
Sinuses
Sinuses are bony cavities through which air flows and play a role in reducing head weight and improving breathing quality. If fluid accumulates in the sinuses instead of air, this can be detected through radiography. The presence of fluid in the sinuses usually indicates infection and requires treatment with antibiotics. Of course, in cases of trauma, fluid (blood and other components) may also be seen. Note: Dogs that enjoy sticking their heads out of moving cars are at risk of becoming infected in the sinuses due to wind hitting their foreheads. In radiography of dogs’ heads, these sinuses are examined and treated.
Nose and Nasal Passages
Nasal passages have a unique structure that should normally contain air and appear completely black in density. If the density increases in radiography and its clarity decreases, it may indicate swelling or fluid accumulation inside the nose that leads to respiratory problems.
Pharynx, Larynx, and Trachea
The airways start from the back of the nose and mouth, extending to the trachea and ultimately the lungs. Radiography can also be used to examine the condition of the mouth, the presence of masses or foreign bodies in the mouth, and dental problems. This information helps the veterinarian determine the source of respiratory issues.
Various Factors Influencing Respiratory Problems
Respiratory problems can arise from various factors. For instance, lymph node involvement in the pharynx due to infection, inflammation of salivary glands, and problems with the esophagus and trachea can also cause respiratory issues. These problems can be identified in head and neck radiography.
Note: The esophagus is normally not visible in respiratory area radiography, but if there is an issue (mass, foreign body, etc.), it can be discovered through head and neck radiography.
The Importance of Radiography in the Accurate Diagnosis of Respiratory Problems in Animals
If the veterinarian suspects respiratory problems and recommends radiography of the respiratory system, in addition to chest radiography, head and neck radiography should also be taken seriously. This examination can provide a lot of information to the veterinarian, upon which treatment for the animal is based and the condition of their recovery improves.
Final Words
Diagnosing and treating respiratory problems in pets requires precision and a thorough examination of the respiratory system. Chest and head radiography are important tools that help veterinarians in accurate diagnosis and providing appropriate treatment. By performing these examinations, we can ensure that our pets are in the best health condition and their respiratory problems are effectively treated.
