OBJECTIVE: Several centers have implemented ambulances equipped with CT scanners and telemedicine capabilities, known as mobile stroke units (MSU), to expedite acute stroke care delivery in the pre-hospital setting. While MSUs have been shown to improve outcomes compared with standard emergency medical management, there are limitations to incorporating CT, including radiation exposure to emergency medical services personnel. Recently, a portable, low-field strength MRI (Swoop®, Hyperfine, Inc., Guilford, CT) received FDA clearance for in-hospital use. Here, as proof-of-concept, we explore the possibility of performing MRI in a telemedicine-equipped ambulance during active transport. MATERIALS AND METHODS: In this initial technical demonstration, we imaged an MR phantom and a normal human volunteer using a standard stroke protocol during active ambulance transport. RESULTS: Images of the MR phantom and volunteer were successfully obtained and were immediately available for viewing in the hospital PACS system. The images were deemed of diagnostic quality by the radiologist. Active motion correction maintained superior image quality despite vehicle and scanner motion. In-plane, low contrast resolution of greater than 4 × 4 mm was achieved. Average transmit speeds were calculated to be 3.54 Megabits/second and upload data rates varied while in transit ranging from 8.54 to 4.13 Megabits/second. CONCLUSION: While MRI is not yet ready for clinical use in the MSU setting, our initial experience suggests potential technological feasible of this approach following future technical and MRI sequence development. Additional studies, incorporating patients, would be required to determine clinical feasibility.
