Structured PICO

Does tube voltage influence pericoronary adipose tissue attenuation values in patients without plaques on cCTA?

Population

Patients without plaques on coronary CT angiography (cCTA)

Intervention

Coronary CT angiography at different tube voltage settings (70 kV, 80 kV, 90 kV, 100 kV, and 120 kV)

Outcome

Pericoronary adipose tissue attenuation values for left anterior descending (LAD), left circumflex (LCX), and right coronary artery (RCA)surrogate

Pericoronary adipose tissue attenuation values on cCTA are significantly influenced by tube voltage, necessitating the use of consistent kV settings for accurate interpretation.

Abstract

OBJECTIVES: ) values for left the anterior descending (LAD), left circumflex (LCX), and right coronary artery (RCA) in patients without plaques on coronary CT angiography (cCTA), taking into account tube voltage influence. METHODS: in different kV groups. RESULTS: of the 70 kV, 80 kV, 90 kV, 100 kV, and 120 kV groups was - 95.6 ± 9.6 HU, - 90.2 ± 11.5 HU, - 87.3 ± 9.9 HU, - 82.7 ± 6.2 HU, and - 79.3 ± 6.8 HU, respectively (p < 0.001). CONCLUSIONS: values need to be interpreted taking into account tube voltage setting. KEY POINTS: , the use of equal kV setting is strongly recommended.
