ARC Turbo

Turbo ARC User CV is used to speed up scan acquisition time. It is available as a User CV if ARC imaging Option is also turned on. It is available with Scan with LAVA Flex Imaging Option Scan with LAVA Flex Imaging Option, VIBRANT with Flex Imaging Option and 3D dual echo scans. Turbo ARC selections include the following:

• Turbo ARC = 0 (off) the default state
• Turbo ARC = 1 (faster)
• Turbo ARC = 2 (fastest)

As you increase the Turbo ARC selection from the default to fastest selection, scan time becomes shorter because the system acquires less ARC self-calibration data. The advantages of a faster acquisition include the following:

• The protocol can better meet the needs of patients with short breath-hold ability.
• The ability to acquire two arterial phases in one breath-hold to simplify the dynamic timing.

The tradeoff for Turbo ARC is an increase in parallel imaging alias artifact, which may occur in certain un-optimized protocols.
