Chest Imaging

Question 1

Atelectasis shifts

Answer 1

Fissures
Vessels
Airways 
Diaphragm
Mediastinum

Question 2

LLL atelectasis

Answer 2

Will pull the left pulmonary artery behind the ehart and won’t be able to see it

Will also lose right angle of heart and diaphragm

Question 3

Obstructive atelectasis

Answer 3

Will appear concave

Involved lung is denser and less air

Post-obstructive pneumonia…normally opacified lung that conforms to lung segment WITHOUT air bronchograms

Question 4

Compressive atelectasis

Answer 4

Something is pushing on the lung

Question 5

Pneumonia CT

Answer 5

COnsolidation with ground glass and no volume loss

Air bronchograms

Question 6

Pleural effusion

Answer 6

Collects between visceral and parietal pleura

Should be uniform density with no lung markings

Question 7

Exudates vs transudates

Answer 7

Ex - inflammation or neoplasia of the pleural surfaces produces capillary leakage (loculated)

Trans - increased HS or decreased oncotic pressure produces leakage of protein POOR fluid

Free-flowing and bilateral…hepatic hydrothorax

Question 8

Diff pneumonia and atelectasis

Answer 8

Fever, leukocytosis, pleuritic chest pain and purulent sputum - pneumonia, NOT atelectasis
