Lecture 6 Flashcards
(13 cards)
Basic imaging techniques used for evaluating a heart?
- chest radiography
-cardiac catheterization and coronary arteriography
-echocardiography
-radio isotope studies (SPECT & PET)
-CT
-MRI
Cardiac CT images
Allow the demonstration of coronary arteries with a high degree of accuracy, approaching that for coronary angiography, very useful for the assessment of congenital heart disease
Cardiac MRI images
Extremely valuable for the assessment of myocardial viability following myocardial infraction, valvulae heart disease and myocardial function
Pectus excavatum
Enlarged heart, ribs are more horizontal posteriorly and steeper anteriorly. Sternal deformity compress the heart
CT coronary angiography
Allow the demonstration of coronary arteries with high degree of accuracy
Assessment of congenital heart disease
CT and MRI
Echocardiography
Diagnostic toll for investigating valvulae disease assessing heart function and wall motion abnormalities, calculating ejection fraction and characterizing pericardial effusions
Motion mode echocardiography
Measuring the depth of each structure awa well as displaying its motion echocardiography provides real time images of the moving heart chambers s
Doppler echocardiography
Allows study of interruptions or obstruction of flowing blood and thus is used primarily to asses the direction and velocity of blood flow in the heart, great vessels an d peripheral arteries and veins. Useful in evaluating the integrity and motion of cardiac valves
Trans thoracic echocardiography
Performed by placing the transducer on the neck chest and abdomen to obtain parasternal
Contrast used for cardiac MRI for ischemic heart disease
Gadolinium
MRI cardiac views
Horizontal long axis/ 4 chamber view
And
Vertical long axis view/ 2 chamber view
Ebsteon anomaly
Huge as heart/ huge water balloon
