Effects of MRgFUS Treatment on Musculoskeletal Pain: Comparison between Bone Metastasis and Chronic Knee/Lumbar Osteoarthritis

Figure 1

The pictures show the corresponding ultrasonic irradiation pathways on the MRI monitor. The blue area represents the ultrasonic irradiation route, and the green circle is the target site for each disease. (a) Irradiation for painful bone metastasis of the ilium. The green circle shows the part with maximal tenderness over the bone metastasis site in the ilium. (b) Irradiation for lumbar facet joint osteoarthritis. The green circle shows the dorsal area of the painful lumbar facet joint. (c) Irradiation for knee osteoarthritis. The green circle shows the bone surface around osteophytes in the medial tibiofemoral joint. (d) Schematic diagram of the pathway of the ultrasonic irradiation to the bony lesion.
