Imaging The Lungs Notes

Veterinary Medicine Notes > Cardiorespiratory system 1 Notes

This is an extract of our Imaging The Lungs document, which we sell as part of our Cardiorespiratory system 1 Notes collection written by the top tier of University Of Nottingham students.

The following is a more accessble plain text extract of the PDF sample above, taken from our Cardiorespiratory system 1 Notes. Due to the challenges of extracting text from PDFs, it will have odd formatting:

NORMAL RADIOLOGY OF THE THORAX Normal ventro-dorsal view. Normal right lateral view

A = aorta B = caudal vena cava C = trachea D = left diaphragmatic crus E = right diaphragmatic crus F = cardiac silhouette

PLEURAL CAVITY ABNORMALITIES Pleural fluid (pleural effusion) Types

1. 2.

3. 4.

"Transudate" Blood Lymph Exudate (pyothorax)

Signs

1. 2.

3. 4.

5. Homogeneous opacity in ventral thorax (frequently "scalloped" lung edges) Partial/complete loss of heart/diaphragm shadow Interlobar fissures seen (fluid between lung lobes) Fluid in thoracolumbar recess in caudodorsal thorax (N.B. normal reflection of lungs in cats) Fluid opacity between lungs and thoracic wall in VD/DV

Pneumothorax Signs

1. 2.

3. 4.

Lucent space between the heart shadow and sternum Lung lobes retracted from the thoracic borders, with no lung markings at the periphery Increased lung opacity (collapse) Film has an overall overexposed appearance

Beware:

1. Small lucent space between heart and sternum in deepchested dogs at peak inspiration
