MRI may also be useful in patients with infantile hemangiomas in anatomic locations, when the presence or growth of the lesion may be disfiguring or interfere with sight or hearing, the face, airway, ears, or breast [17]. MRI Area of Interest Without IV Contrast There is no relevant literature to support the use of MRI of the area of interest without IV contrast as the initial imaging modality for infants with infantile hemangiomas. Radiography Area of Interest There is no relevant literature to support the use of radiography area of interest as the initial imaging modality in infants with infantile hemangiomas. US Area of Interest Ultrasound (US) of the area of interest is useful to distinguish imaging features of infantile hemangiomas from VMs. Paltiel et al [21] studied 49 lesions and Ding et al [14] studied 66 lesions, describing US imaging characteristics of superficial and deep infantile hemangiomas from well-circumscribed mixed echogenicity solid masses with central and peripheral vessels on grayscale US. Both groups showed that US is useful in distinguishing infantile hemangiomas from VMs and for identifying infantile hemangiomas, which may be combined with other VA components [14,21]. US Area of Interest With IV Contrast There is no relevant literature to support the use of US area of interest with IV contrast as the initial imaging modality in infants with infantile hemangiomas. US Duplex Doppler Area of Interest US with duplex Doppler is most useful to assess and confirm diagnosis of infantile hemangiomas. Paltiel et al [21] studied 49 lesions and Ding et al [14] studied 66 lesions, showing that a combination of arterial and venous waveforms on US duplex Doppler enables distinguishing infantile hemangiomas from low-flow VMs.
