Lecture 18: Thoracic Ultrasound Flashcards
Ultrasound does not penetrate __, can’t see into __, just the surface
air, lung
thoracic ultrasound very useful for pleural ___
fluid
thoracic ultrasound useful for determine __ vs___
body wall vs lung
t or f: you can dx diaphragmatic hernia with ultrasound
true
ultrasound notice fluid near the heart, but the heart is not wobbly and there is no compression of ventricles or atria. What is likely dx
pleural effusion
ultrasound of heart, notice fluid near the heart and heart is wobbling. Compression of ventricles and atria What is likely dx
Pericardial effusion
what is a major sequela to pericardial effusion
tamponade
what is difference between pleural and pericardial effusion on ultrasound
heart motion and compression of atria and ventricles with pericardial effusion
take an ultrasound of thorax and notice spleen is up by the heart, what wrong
diaphragmatic hernia
Take ultrasound near heart and notice liver is beating with the heart, what is dx
pericardial diaphragmatic hernia
thoracic metastasis is not seen if less than __mm
5
what wrong
thoracic metastasis
ultrasound of thorax what wrong
nodules- thoracic metastasis
how should you position animal for ultrasound of heart
elevate animal, image through collapsed/down side lung
how is probe positioned for short axis view
points towards elbows
how is probe positioned for long axis view
points towards shoulders
what view is this and identify 1-10
View: right parasternal long axis, 4 chamber view
1. RV
2. TV
3. RA
4. Ventricular septum
5. Chordae tendinae
6. MV
7. LV
8. LA
9. LWV
10. Papillary muscles
what view is this and identify 1-9
View: right parasternal long axis 5 chamber view
1. RV
2. TV
3. RA
4. Aorta
5. Aortic valve
6. LV
7. MV
8. LA
what view is this and identify 1-3
Right parasternal long axis (LV inflow/outflow) view
1. RV
2. LV
3. LA
what view is this and what is it basis for. Identify 1-2
Right parasternal short axis view of ventricles
Basis for M mode
1. RV
2. LV
what view is this, identify 1-3
right parasternal short axis view, mid LV (mitral valve) view
1. RV
2. LV
3. MV
what view is this and identify 1-5
Right parasternal short axis (heart base or basilar view)
1. RA
2. RV
3. Aorta
4. LA
5. Pulmonary valve
what view is this and identify 1-4
Left apical position 4 chamber view
1. RV
2. LV
3. RA
4. LV
what measurement is being used here /mode
M mode
what view is M mode done on
short axis LV view
what are the 4 measurements for M mode
- IVSd- interventricular septum diastole
- IVSs- interventricular septum systole
- LVFd- left ventricular free wall diastole
- LVFs- left ventricular free wall systole
do not measure in M mode after __
arrythmias
do not include __ in M mode image/measurement
papillary muscles
what does this show and what mode
Arrow: mitral valve E separation- almost touching interventricular septum
Shows E point- septal separation
what does this show and what is it associated with
Right parasternal short axis, LV mitral valve
SAM arrows pointing at open mitral valve- should be closed
Associated with dynamic left ventricular outflow tract obstruction and hypertrophic open cardiomyopathy
