Real-Time Imaging Overview
“Real-time” imaging modalities such as fluoroscopy and duplex ultrasound are used at Minnesota Regenerative Medicine (MRM) when necessary to confirm precise needle placement during injection of bone marrow aspirate concentrate (BMAC), fat aspirate concentrate (FAC), and platelet-rich plasma (PRP). In the photo on the right, a tiny 25-gauge needle is being shown precision guided into the left shoulder joint of an MRM patient receiving a PRP injection to treat rotator cuff tendinitis.
In the photo on the left, a tiny needle has been inserted through the skin lateral to the patellar tendon then precision advanced into the knee joint using fluoroscopy “real-time” guidance. While the tip of the needle remains in very close proximity to the femoral condyle (bony) portion of the knee joint, fat aspirate concentrate (FAC) is injected to treat knee osteoarthritis. Bone and joints are best visualized using fluoroscopy, whereas skin and soft tissue such as skin wounds, muscles, tendons, and ligaments are best visualized using high-resolution ultrasound.
Whether our regenerative medicine specialists are injecting skin, soft tissues, or musculoskeltal tissues such as shoulder, hand/wrist, elbow, hip, knee, ankle, or feet, we believe our “real-time” imaging has eliminated the uncertainty and inconsistency of needle placement to the benefit of our patients. Unlike corticosteroid injections and visco-supplement (hyaluronic acid) joint injections that require a large gauge needle to be used to allow for injection of thick or viscous agents, at MRM, small needles are routinely used during injection of BMAC, FAC, and PRP.
