Internal jugular vein: Peripheral vein adrenocorticotropic hormone ratio in patients with adrenocorticotropic hormone-dependent Cushing's syndrome: Ratio calculated from one adrenocorticotropic hormone sample each from right and left internal jugular vein during corticotrophin releasing hormone stimulation test.

Background: DEMONSTRATION OF CENTRAL: Peripheral adrenocorticotropic hormone (ACTH) gradient is important for diagnosis of Cushing's disease.

Aim: THE AIM WAS TO ASSESS THE UTILITY OF INTERNAL JUGULAR VEIN (IJV): Peripheral vein ACTH ratio for diagnosis of Cushing's disease.

Materials And Methods: Patients with ACTH-dependent Cushing's syndrome (CS) patients were the subjects for this study.
