Answer

Precordial Doppler ultrasonography is the most sensitive noninvasive method for detecting venous air emboli. This modality is capable of detecting as little as 0.12 mL of embolized air (0.05 mL/kg). [1, 15, 22, 23, 38]

Transcranial Doppler ultrasonography is another imaging modality commonly used to detect cerebral microemboli. [1]
