Background The face is known for its extreme variation in vascular anatomy. Furthermore, the rapidly increasing number of filler treatments leads to an increase in severe filler-associated complications (such as skin necrosis and blindness) due to intra-arterial injection. Visualizing a patient’s individual complete facial arterial anatomy in a contrast- and radiation-free way has not been published before. This innovative imaging technique could, therefore, enhance the safety of minimally invasive surgical procedures as it provides a harmless way to map the arteries of the face. Objectives Evaluate a newly developed imaging technique to visualize the arteries of the face in a noninvasive and radiation-free manner. Methods The individual arterial facial anatomy of 20 volunteers was studied by an imaging technique, combining infrared (IR) facial warming and 3-dimensional (3D) time of flight (TOF) magnetic resonance angiography (MRA). The source and maximum intensity projection images were assessed by 2 investigators, familiar with the anatomy of the face. Results The MRA technique visualized most of the main facial arteries, albeit in a variable way. The main facial branches of the external carotid artery (facial, angular, supralabial, and superficial temporal arteries) were illustrated well, whereas the visualization of the internal carotid branches (supratrochlear and supraorbital arteries) and nasal branches (dorsal nasal and lateral nasal arteries) was less consistent. Conclusions The combination of IR “heat-induced enhancement” and a 3D-TOF MRA sequence may actually be an important step toward the visualization of the variable facial vascular anatomy in a noninvasive, radiation-free, and contrast-free manner.

Background As the face is known for its extreme variation in vascular anatomy and the number of filler‐associated complications due to intra‐arterial injection is increasing, we are in need of a method to visualize anyone’s individual arterial anatomy of the face in a completely harmless way. Aims The different medical imaging methods and a recently developed MRA protocol are reviewed. Methods The literature of the last twenty years—with special attention for the last five years—concerning the different medical imaging modalities of the facial arteries was reviewed. Results A harmless visualisation of the facial arteries is currently only possible with US or MRA. US may identify single vessels but never the complete arterial network. A combination of IR “heat enhancement” and a MRA 3D‐TOF sequence might make it feasible to visualize a large number of facial arteries in a risk‐free, radiation‐free, contrast‐free and non‐invasive way. Conclusion Currently, a new combination of IR “heat enhancement” and a MRA 3D‐TOF sequence might be the only method to visualize a large number of facial arteries.

“…Alternatively, noninvasive magnetic resonance imaging (MRI) techniques, such as magnetic resonance angiography (MRA) without contrast medium, have been developed to identify and characterize peripheral blood vessels located in the thoracic, abdominal, lower extremity, head, and neck regions [ 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 ]. We have also conducted several studies regarding the delineation of peripheral blood vessels in the head and neck region [ 8 , 12 , 13 ]. In one of these, we reported non-contrast-enhanced MRA using steady-state free-precession (SSFP) with a time–spatial labeling inversion pulse (time–SLIP) as a highly useful technique for visualizing thin, main peripheral arteries in the oral and maxillofacial regions.…”

The aim of this study was to evaluate whether a balanced steady-state free-precession (SSFP) sequence with a time–spatial labeling inversion pulse (time–SLIP) without contrast medium could elucidate branches of the lingual and facial arteries on the lingual aspect of the mandible as a potential technique for preventing severe complications in dental implantation surgery. In this study, magnetic resonance angiography (MRA) using SSFP with a time–SLIP was evaluated in 40 subjects. The outline and course of branches of the lingual and facial arteries near the mandible were assessed clinically in the same subjects against contrast-enhanced computed tomography (CT) images as the gold standard. The submental, sublingual, and deep lingual arteries could be visualized via MRA in 16, 20, and 16 of the 40 subjects, respectively. The major axes of the respective arteries were approximately 24, 24, and 16 mm. The outline and course of all visualized arteries coincided with those on CT. MRA using SSFP with a time–SLIP appears to have potential as a non-contrast technique for visualizing branches of the lingual and facial arteries on the lingual aspect of the mandible. Information regarding the outline and course of these arteries as obtained using this MRA technique could assist in preventing severe complications in dental implantation surgery.
