Radiology 2 Flashcards
An endotracheal tube should be _________ above the carina on XR.
2-5 cm (depending upon patient size)
the Carina is typically located at the T4-T5 interspace
The tip of a central venous line should be in the
distal 1/3rd of the SVC and no further than the SVC to RA junction
A pulmonary artery catheter should be visualized coursing from
the SVC–> RA–> RV–> Pulmonary artery in West’s zone 3
When evaluating a cardiac implanted electronic device, you should look at
the location and integrity of the leads
The tip of the ICD or pacemaker leads should be
embedded in the endocardium
To diagnose a misplaced cardiac lead, you’ll need
two views (PA and lateral)
List 4 ways you can determine whether the ETT is at the correct depth on CXR
mid-trachea
4-5 cm above the carina
4-5 cm above T4-T5
at level of the medial ends of the clavicles
What is the FIRST radiographic sign of pulmonary edema?
a. cardiac enlargement
b. cephalization
c. Kerley B lines
d. Pleural effusion
B. cephalization
The 1st stage of cardiogenic pulmonary edema is
cephalization- redistribution of vascular markings to the upper lung
The 2nd stage of cardiogenic pulmonary edema is
peribronchial cuffing and Kerley lines (A & B)
The 3rd stage of cardiogenic pulmonary edema is
alveolar edema, pleural effusion, and increased cardiac size
_______ occurs in 90% of patients under general anesthesia & is not usually detectable by chest radiography
Basilar atelectasis
Radiographic evidence of aspiration is most likely to occur in
the RUL or RLL
A tension pneumothorax is characterized by a
depressed diaphragm, flattened right cardiac border, and contralateral mediastinal shift
Multiple traumatic rib fractures may be associated with
opacities due to lung contusion or pneumothorax
