Can angiography be negative?
Background: Angiogram negative sub-arachnoid haemorrhage (SAH) is generally considered to have a more benign course than SAH of known cause.
There is also variability from centre to centre as to what proportion of angiogram negative SAH patients undergo repeat Digital Subtraction Angiography (DSA)..
How accurate is a CT angiogram?
It was found that CT angiogram identified 85% of patients with significant stenoses and 90% of patients with CAD accurately..
Is a coronary CT negative?
A Cardiac CT has a negative predictive value of over 99%.
This means that when the study is reported to be normal, you can be rest assured that you don't have a coronary artery disease..
What is the disadvantage of CT angiogram?
Risks of CT angiography
Small amount of radiation.
The amount of radiation you are exposed to depends on the number of pictures taken and the part of the body being examined.
Extremely small chance you could develop cancer in the long term from the radiation.

A Cardiac CT has a negative predictive value of over 99%.
This means that when the study is reported to be normal, you can be rest assured that you don't have a coronary artery disease.
A computed tomography angiogram (CT angiogram) is a test that uses X-rays to provide detailed pictures of the heart and the blood vessels that go to the heart, lung, brain, kidneys, head, neck, legs, and arms.
This test can show narrowed or blocked areas of a blood vessel.
It was found that CT angiogram identified 85% of patients with significant stenoses and 90% of patients with CAD accurately.
