Study Notes
Imaging the Thorax
- Radiography, ultrasonography, and computed tomography are primary imaging modalities for thoracic evaluation.
- Preferred positioning for radiography is right lateral to avoid axial rotation of the thoracic structures.
- Centering and collimation are crucial to ensure focused images.
- Dorsal-ventral (DV) and ventral-dorsal (VD) views should be aligned to the midline to maintain correct orientation and avoid rotation.
- For optimal exposure, images should be taken at peak inspiration to clearly visualize the diaphragmatic outline.
- Proper labelling of images is essential for clarity in assessment.
- When assessing images, avoid artefacts using the mnemonic: Pink Camels Collect Extra Logs.
Assessing
- Ventral and central veins are key in evaluating vascular anatomy in the thorax.
- Lung anatomy includes examining branching patterns and markings, noting both normal and abnormal features.
- Assess heart anatomy for signs of generalized and chamber-specific enlargement, which can indicate underlying pathology.
Normal Heart
- In dogs, the normal heart width on DV view is approximately two-thirds of the thoracic width.
- In lateral views for dogs, the heart size should occupy between 2.5 to 3.5 intercostal spaces.
- Normal width measurements for cats require additional specification and comparison for accurate evaluation.
