Highlights • Superiority of spiral versus sequential cCT in image quality and organ-specific-radiation dose. • Spiral cCT: lower organ-specific-radiation-dose in eye lense compared to tilted sequential cCT. • State-of-the-art IR spiral cCT techniques has significant advantages over sequential cCT techniques.
