1

Imaging Modalities used to view the heart? (6)

CXRAngiographyEchocardiographyCTMRINuclear Cardiology

2

3 advantages of x-rays and 2 disadvantages

Advantages: Easy to doImmediately availableAnswers available soonDisadvantages:RadiationNon-specific sometimes

3

Cardiothoracic ratio (CTR)?

The ratio of the maximum diameter of the heart divided by the maximum diameter of the diaphragm

4

What should the normal CTR be?

Less than or equal to 50%

5

When is heart size exaggerated on CXRs?

When the AP projection is poorly inspired rotated

6

Advantages (4) and disadvantages (5) of angiography?

Advantages:Excellent coronary arterial depiction Assess anomaliesassess coronary plaques/ stenosis Assess stents/ CABGsDisadvantages:Radiation InvasiveComplicationsMay need admissionsContrast allergy/ nephropathy

7

Advantages (5) and disadvantages (3) of Echocardiography?

Advantages:Immediately availableFunctional assessment of the heartValvular assessmentChamber assessmentNo radiationDisadvantages:Operator dependantPatient dependant Incomplete cardiac assessment

8

Advantages (5) and Disadvantages (4) of Cardiac CT following IV contrast?

Advantages:excellent cardiac anatomy depictionNon-invasive coronary artery assessmentFunctional assessment Chamber assessmentLook at vessels and lungsDisadvantages:Radiation doseResolution still slightly less than catheter angiographyPotential for contrast allergy/ nephropathyNeed special CT equipment/ expertise

9

Cardiac MRI advantages (5) and disadvantages (5)

Advantages:No radiationExcellent soft tissue resolutionAnatomical assessmentGold standardFunctional assessmentDisadvantages:Long imaging timesClaustrophobiaMRI contraindicationsNeed special MRI equipment / expertiseNot very useful for coronary arteries at present

10

What is nuclear cardiology normally used for?

To determine the impact of coronary artery disease on regional myocardial perfusion
