Abstract

Superb microvascular imaging (with Doppler Luminance) and SlowflowHD can detect low-velocity blood flow in fetal peripheral small vessels by significantly reducing motion artifacts. Fetal intracranial, intrathoracic, intra-abdominal, and small arm and leg vessels can be clearly identified using these techniques. Moreover, microvasculature of the lung, liver, spleen, adrenal gland, and kidney can also be noted. Superb microvascular imaging (with Doppler Luminance) and SlowflowHD may become a future modality to provide novel information on the antenatal diagnosis of fetal normal and abnormal peripheral vascularities, and the physiologic progress and pathologic etiology of fetal intrathoracic and intra-abdominal organs in clinical practice and future research.
