CT Angiogram & MRI

 

 

CT Coronary angiogram

 

A CT coronary anngiogram is a virtual coronary angiogram performed in a equipped radiology suite. This test is different to a formal coronary angiogram performed in hospital. A drip is placed in the arm and a specific CT scanner "reconstructs" the coronary arteries. It is used in patients with chest pain or shortness of breath at low or intermediate risk of coronary disease. 

 

Advantages

 

1. Quick 

2. Admission to hospital not required

3. If normal then excludes obstructive coronary disease (except coronary spasm)

4. Excellent for excluding anomolous coronaries origins

5. Very good at assessing venous drainage

6. Low radiation dose in expert centres

 

 

Disadvantages

 

1. Requires a low resting heart rate for optimal images

2. Difficult to perform in anxious patients

3. Heavy calcification makes it difficult to assess the severity of stenoses

4. Requires iodine contrast

5. Not ideal for patients with significant renal impairment or severe contrast allergy

6. Narrowings cannot be fixed at the same time as with invasive coronary angiography
