Cardiac Radiology Flashcards
Mainstay for imaging of the heart
Provides the initial evaluation of the heart
Chest radiography
This can provide dynamic information
Fluoroscopy
Divide the widest transverse diameter of the heart by the widest transverse of the thorax
Cardiac thoracic ratio
cardiac ratio should not exceed on erect PA
0.50
Should not exceed on portable AP
0.60
What can straigthen the left border of the heart
Rheumatic heart disease
Mitral stenosis
What can cause a water bottle configuration
Pericardial effusion
Generalized cardiomyopathy
Boot shaped heart
TOF
Figure of 3 sign
Coarctation
Snowman shape
TAPVR
Left atrial enlargement is how many cm
7cm
On lateral view, an enlarged LA will displace the bronchus posteriorly
Walking man sign
More than 5.5cm from the midline on a well positioned PA
Right atrial enlargement
Left ventricular enlargement with the apex pointing downward on PA
Shmoo configuration
LV extends mlre than 1.8cm posterior to the posterior border of the IVC
Hoffman rigler
PA, RT and LT are enlarged
Pulmonary Arterial Hypertension
Necrotizing vasculitis of medium sized pulmonary arteries
Small PA aneursym
PAN
Deceased pulmonary blood flow with a small heart
COPD
Hypovolemia
Malnourishment
Addison disease
Increase flow to the LT lung
Pulmonary valvular stenosis
Pressure of pulmonary venous HTN
Mile 10-13
Moderate 14-16
Severe 17-20
May provide useful crossectional information for MI
Help assess the cavity and dimensions
CT scan
MI assessment of scar tissue
MRI
Myocardial edema can be seen
Acute phase of infarction
Gold standard for the treatment of ST elevation of MI
Angiography
Cardiac silhoute of egg on its side and apple on a stem
TGA
Wide mediastinum due to large aortic shadow
PTA
Ballon or box shaped
Marked cardiomegaly
Ebstein anomaly
