A dose display presented at the RSNA – Radiological Society of North America, available on the Image Wisely website, reviews adrenal venous sampling (AVS) techniques and offers several tips for reducing radiation dose, contrast material, and time to procedure with a high technical success rate in segmental AVS.

The purpose of this exhibition is to review AVS techniques, including a segmental sampling of effluent tributaries, which allows the assessment of intra-adrenal hormone distribution. Besides, it features different doses, contrast material, and procedural time reductions – while maintaining the high technical success rate in segmental AVS in high-volume centers.

This type of exam was recently introduced to detect and locate intra-adrenal aldosterone secretion for more precise localization and compensation for sampling failure in the main trunk, with the possibility of partial resection.

Radiation exposure may increase in patients as the procedure takes longer.

The authors of the article are from the Women’s Medical University Hospital of Tokyo, Japan, who presented the following data:

• More than 100 procedures are performed per year at the institution;
• The average time is one hour;
• The sucess rate is 98%.

The Hospital performs the procedure systematically to obtain these results, using several techniques developed on site. By reducing the dose, contrast, and time factors, the patient’s stress decreases and improves operator performance and optimizes time for segmental AVS and retraining.
