CAD-RADS™ 2022 (v 2.0)

Coronary Artery Disease - Reporting and Data System

Initially published in 2016, the Coronary Artery Disease Reporting and Data System (CAD-RADS) is a standardized reporting system for coronary CT angiography developed by the Society for Cardiovascular Computed Tomography (SCCT), the American College of Radiology (ACR), and the North American Society for Cardiovascular Imaging (NASCI), which has also been endorsed by the American College of Cardiology (ACC).

CAD-RADS

What is the patient's status? *

Acute chest pain

Stable chest pain

What is the maximal degree of stensosis? *

1-24%

25-49%

50-69%

70-99%

100%

Cannot evaluate due to motion or other artifacts

Are there any vessels that cannot be evaluated due to motion or other artifacts? *

Yes

In other words, cannot exclude obstructive CAD

Does the patient have atherosclerotic plaques? *

Yes

Does any of the following apply? *

There is three vessel disease

Left main stenosis is ≥ 50%

Both apply (3VD and L main ≥ 50%)

Neither apply

How severe is the plague burden? *

P1: Mild* (1-2 vessels with mild amount of plaque)

P2: Moderate† (1 -2 vessels with moderate amount; 3 vessels with mild amount of plaque)

P3: Severe§ (3 vessels with moderate amount; 1 vessel with severe amount of plaque)

P4: Extensive amount¶ (2-3 vessels with severe amount of plaque)

* P1 = CAC 1-100, or SIS ≤2
† P2 = CAC 101-300, or SIS 3-4
§ P3 = CAC 301-999, or SIS 5-7
¶ P4 = CAC >1000, or SIS ≥ 8

Does the patient have high risk atherosclerotic plaques* (HRP)? *

Yes

*High-risk plaques have two or more high risk features which include spotty calcifications, low attenuation plaque (less than 30 Hounsfield Units), positive remodeling, and the “napkin ring sign”

Does the patient have any stents? *

Yes

Does the patient have any grafts? *

Yes

Does the patient have any non-atherosclerotic causes of coronary abnormalities*? *

Yes

* Non-atherosclerotic causes of coronary abnormalities such as: Coronary dissection, Anomalous origin of the coronary arteries, Coronary artery aneurysm or pseudoaneurysm, Vasculitis, Coronary artery fistula, Extrinsic coronary artery compression, and Arterio-venous malformation

Are either CT-FFR or CCTA available? *

CT-FFR

CCTA

Neither are available

How are the results of CT-FFR? *

Normal (>0.80)

Abnormal (≤ 0.75)

Borderline (0.76-0.80)

How are the results of the CCTA? *

No ischemia

Presence of a prior fixed myocardial infarct

Myocardial ischemia (reversible perfusion defect)

Peri-infarct ischemia (perfusion defect during stress larger than rest perfusion defect)

If you are human, leave this field blank.
