[Measurement of Head and Neck Exposure in CT Guided IVR].

In April 2011, the International Radiological Protection Committee recommended that "The equivalent dose of the crystalline lens should not exceed 20 mSv/year, averaged over defined periods of 5 years, with no single year exceeding 50 mSv". Based on this recommendation, it is predicted that the equivalent dose limit of our crystalline lens can be lowered in the near future. Therefore, it is important to grasp the current situation of radiation exposure.

Image-guided radiofrequency ablation for adrenocortical adenoma with Cushing syndrome: outcomes after mean follow-up of 33 months.

Objectives: To evaluate the feasibility, safety, and therapeutic effects of image-guided radiofrequency (RF) ablation used for the treatment of adrenocortical adenoma with Cushing syndrome.

Methods: From February 2003 to May 2005, 4 consecutive patients with adrenocortical adenoma and Cushing syndrome received percutaneous RF ablation. All tumors were in the left adrenal gland, with a mean tumor size of 2.

Percutaneous radiofrequency ablation with transarterial embolization is useful for treatment of stage 1 renal cell carcinoma with surgical risk: results at 2-year mean follow up.

Objectives: Despite laparoscopic partial nephrectomy and laparoscopic cryotherapy being performed lately, an even less invasive treatment would be desirable in high-risk patients. Under local anesthesia with i.v.
