Radiology of Heart and Lungs Flashcards
Standard projections are named according to […]
The direction of the x-ray beam
I.e. Posterior-Anterior View (PA) the beam first hits the posterior surface of the patient then the anterior surface
A standard PA view xray shows what anatomy?
Lungs
Bony thoracic cavity
Mediastinum
Great vessels
How/why would you perform a lateral chest x-ray?
How: see image, left side against detector to minimize visualization of heart and maximize that of lungs
Why: do it this way to look more at lungs than heart
Do this in conjunction with PA views
What type of xray view is this?
PA view
When would you do an AP erect view?
- Magnifies the visualization of the heart more than the lungs compared to PA view
- Can be done with mobile x-ray unit if needs to be done outside radiology dept.
When would you do an AP supine view?
When the person has experienced trauma or is critically ill, they need to be laying in bed and this view can be done then
When/why would you do a lateral decubitus view?
If you are trying to visualize a:
- Pneumothorax
- Trapped air due to inhaled foreign body
- Pleural effusion
- Intra abdominal free air
When/why would you do an expiratory view?
To evaluate for pneumothorax or trapped air
How will the heart appear on an AP view compared to a PA view?
Magnified in size
CT scans are [more or less] radiation than xrays.
More
Ultrasound is particularly good for visualizing what?
Things that involve fluid.
Ultrasound and MRI [do / do not] expose a patient to radiation.
Do not
