Carotid artery wall thickness measured using CT: inter- and intraobserver agreement analysis

Area of Science:

• Cardiovascular Imaging
• Radiology
• Medical Imaging Analysis

Background:

• Coronary artery disease assessment requires accurate measurements.
• Coronary artery-to-wall thickness (CAWT) is a potential biomarker.
• Standardized measurement techniques are crucial for CAWT analysis.

Purpose of the Study:

• To evaluate inter- and intraobserver agreement for CAWT measurements.
• To assess the reproducibility of CAWT quantification using MDCTA.
• To determine the reliability of MDCTA for CAWT analysis.

Main Methods:

• Multi-detector computed tomography angiography (MDCTA) was used for imaging.
• Coronary artery-to-wall thickness (CAWT) was quantified in 35 patients.
• Inter- and intraobserver agreement was assessed using Bland-Altman statistics.

Main Results:

• MDCTA measurements of CAWT demonstrated good reproducibility.
• High agreement was observed between different observers (interobserver).
• Consistent results were found within the same observer (intraobserver).

Conclusions:

• CAWT measurement using MDCTA exhibits good reproducibility.
• The findings support the reliability of MDCTA for CAWT quantification.
• This technique shows promise for consistent clinical application.
