Week 5 Flashcards
What is the best way to become proficient at interpreting x-rays and other medical imaging tests
read them systematically
Identify
- who is patient - is this correct patient? - age/sex - when was exam taken? - are there prior exams - clinical hx?
- Technique, view, quality?
- How is this tken?
- Quality?
PA and lateral CXR, PA and lateral, good (not blurry, can see spine, )
What can happens if you take image during expiration?
- could look like cardiomegaly
view, how was it taken, quality?
- AP portable CXR
- taken in a bed in the ED/ ICU
- not good, obscued by tubes and lines
What is the exam and view depicted? How was it acquired?
AP CXR? Patient in ICU lying down.
Modality and view depicted?
Describe abnormality.
PA and lateral CXR
- LLL infiltrate/ pneumonia
Imaging modality and view?
- abnormality?
- sex?
- dx?
PA CXR
Pulmonary nodules/masses
woman
woman with metatatic breast cancer
Modality and views depicted
abnormality
PA and lat CXR
RML infiltrate/pneumonia
imaging exam?
- what is A?
- what is B?
- What is C?
- normal PA chest x-ray
- Aortic arch
- Hila/central pulmonary vessels
- Heart
What is this?
CT of thoracic Aortic Aneurysm
What is this?
Thoracic aorta ectasia and aneurysm
What is wrong?
Hila and central pulmonary vessels are enlarged
What are imaging modality and view?
what is wrong with the heart?
- how to grossly define?
- when can this occur?
PA chest
Cardiomegaly w/ hilar enlargement and pulmonary vascular congestion
- defined on PA CXR when transverse diameter of heart exceeds 50% of the transverse diameter of the lower chest
- CHF
Imaging modality and views? Abnormality?
PA and lateral CXR
- Pleural effusion
Imaging modality and views?
A = PA CXR
B = lateral CXR (most sensitive view to look for a small pleural effusion)
C = L lateral decubitus (L side of pleura is thickened = free-flowing L pleural effusion) –> fluid on dependent L side shifts during a pleural effusion (see space between the lateral rib margins & the pleura)
Imaging modality and view?
abnormality?
- PA CXR
- Large R pneumothorax
Imaging modality and view?
describe abnormalities
AP CXR
Tension pneumothorax
imaging modality and view?
abnormality
- how old i the patient?
Lateral CXR
osteophytes that are bridging between vertebrae –> aka syndesmophytes
This is an older patient –> can tell on imaging
Imaging modality and view?
- abnormalities?
PA CXR
Air under the diaphragm is abnormal (an emergency with the exception of a post-op laparoscopic surgery –> abdomen would be inflated)
This older patient has a bowel perforation
