Question 6#Print Question

Review the MPR images of a coronary artery shown below:

Which one of the following do the images indicate?

a. >50% stenosed mixed morphology plaque in the circumflex artery
b. >50% stenosed mixed morphology plaque in the left anterior descending artery
c. <50% stenosed mixed morphology plaque in the left anterior descending artery
d. >50% stenosed non-calcified plaque in the first diagnonal artery
e. <50% stenosed mixed-morphology plaque in the first diagonal artery


Question 7#Print Question

Concerning plaque characterization, which one of the following is false?

a. The Hounsfield attenuation value correlates closely with the characterization of predominantly fatty versus fibrous plaque
b. The Hounsfield attenuation value correlates closely with the characterization of predominantly calcified versus non-calcified plaque
c. CT plaque morphology has been closely correlated with intravascular ultrasound (IVUS)
d. Vulnerable plaque cannot be identified using CT
e. CT is the best non-invasive modality to diagnose preclinical coronary artery disease


Question 8#Print Question

Concerning aortic valve disease, which one of the following statements is true?

a. The degree of aortic valve leaflet calcification, as quantified by CT, correlates closely with the severity of aortic stenosis
b. Aortic valve planimetry measured using CT does not correlate well withTOE
c. Severity of valve regurgitation can easily be assessed using cardiac CT
d. Peri-prosthetic aortic valve replacement abscesses can be well delineated using CT
e. Significant coronary artery disease cannot be reliably excluded prior to aortic valve replacement using CT


Question 9#Print Question

A 55-year-old woman presents to the ED with recent-onset central chest pain presenting intermittently at rest, relieved by GTN, but not exacerbated by exertion. Her troponin I level and resting ECG are normal. She has no significant risk factors for coronary artery disease.

According to the NICE guidelines, what is the most appropriate subsequent management?

a. Exercise treadmill test
b. Stress perfusion imaging
c. Catheter coronary angiography
d. CT coronary angiography
e. CT coronary calcium score


Question 10#Print Question

A 78-year-old male ex-smoker was referred to the cardiology department with a history of COPD, dizziness, syncope, and exertional symptoms suggestive of angina. He had a suboptimal exercise tolerance test due to dyspnoea and could not tolerate dobutamine during stress echocardiography. He was referred for a cardiac CT. A CT coronary calcium score was performed first and this is shown below.

 According to NICE guidelines, what is the most appropriate next step in management?

a. Proceed to CT coronary angiography
b. Catheter coronary angiography
c. Adenosine stress perfusion MRI
d. Lung function tests
e. Discharge with no further investigation
