If you have had radiation for painful bone mets and are still suffering from pain, or you have reached a maximum dose or refuse to have radiation, Exablate may be a treatment option for you.

However, your doctor is the best person to ask this question as Exablate is not suitable for all patients.

In general, people who cannot undergo MRI imaging will not be able to have the focused ultrasound treatment. This includes patients with metallic implants, patients who are claustrophobic, patients who are allergic to contrast agents (a dye used to see blood vessels during MR imaging), or patents weighing more than 135Kg | 298 lbs.

  • Dizziness
  • Back or leg pain that persists for a few days
  • Mild skin burns (rare)
  • Allergic reaction to contrast media or medications
  • Nausea and/or fever
  • Transient discomfort or pain

Most patients feel pain relief within a few days and many reduce their intake of pain killers. The published results of patients suffering from pain due to bone metastases show that 56% of patients undergoing Exablate reported substantial pain relief within three days of their treatment and nearly 70% experience significant pain relief at 10 days after the treatment, lasting for 3 months.[1] Almost half of the patients who experienced pain relief decreased their opioid and non-opioid analgesic intake following treatment.
