Examples of MedWaves at Work

The MedWaves AveCure generator and probes have been used in a variety of applications.

Primary Lung Tumor Treatment

83-year old female with primary lung tumor, temperature-mode ablation at 110°C and 11 minutes. Below, from left to right:

  • Pre ablation image showing tumor and satellites nearby.
  • During ablation image shows ground-glass effect of microwave coagulation in and around the tumor.
  • Post ablation images at one month follow-up showing scar tissue with no tumor enhancements.

The ablation was performed April 2009 and the patient has no signs of recurrence.

Lung Carcinoid Tumor Treatment

79-year old female with lung carcinoid, power-mode ablation at 28 watts, 100°C – 100°C and 12 minutes. Below, from left to right:

  • Pre-ablation image showing tumor next to aorta growing front to back and top to bottom.
  • Pre-ablation image shows one of placements of antenna.
  • Post-ablation image showing ground-glass effect of microwave coagulation in and around the tumor.

Post ablation images at six months follow-up showing scar tissue with no tumor enhancements and shrinkage of tissue.

Liver Tumor Treatment

70-year old male with two colorectal metastasis in the liver, temperature-mode ablation at 110°C. Below, from left to right:

  • Pre-ablation image showing tumor next to the hepatic veins.
  • Post-ablation image showing ablation zone between the veins.
  • Post-one-month-ablation image showing with shrinkage and no enhancements.
  • Pre-ablation image shows smaller tumor more peripherally. Post ablation images showing ellipsoidal zone from 5 minute energy applications

Post ablation one month follow-up showing scar tissue with no enhancement and tissue shrinkage.

Bone Tumor, Osteoid Osteoma Treatment

13 year old male, right hip Osteoid Osteoma, in pain for several months with a sclerotic rim ablated using minifield antenna, power-mode, 16 watts, 80°C and one minute. Below, from left to right:

  • Pre-ablation MRI T1W and T2W images showing the tumor in right femoral head.
  • Pre-ablation image shows mini field antenna in position for treatment.
  • Pre- and post-ablation dynamic MRI images show complete revascularization of tumor and ablated zone.

Complete pain relief the day after ablation.
