Imaging findings OR Procedure details
Capability of MDCT to detect adrenal vein:
MDCT precisely detects the right adrenal venous location and course with information of accessory hepatic veins.

Anatomical types of the right adrenal vein and newly developed catheters for right adrenal venous sampling
We classified right adrenal venous anatomy into 5 types (upward type,
downward type,
medial insertion type,
medial direction type,
and common trunk with accessory hepatic vein), developing 5 types of catheters (Adselect series,
Hanako Medical,
Tokyo,
Japan) suitable for each anatomy.

Success rate of adrenal venous sampling
We achieved success rate of more than 99% utilizing MDCT information using the newly developed catheters.
Successful management of primary aldosteronism patients
Unilateral aldosterone hypersecretion can be successfully distinguished from bilateral idiophathic adrenal hyperplasia.
Unilateral aldosterone producing adenoma can be adequately treated by laparoscopic adrenalectomy.
