Adrenal washout is used to diagonise the adrenal adenoma in a patient. The Adrenal washout is calculated using the density value of an adrenal mass on non-enhanced, portal venous phase and 15 minutes delayed CT-scans. In radiology, >60% washout is highly suggestive of adrenal adenoma and >40% washout is highly suggestive of adrenal adenoma. The given radiology calculator assists you in calculating the adrenal washout level in a patient.
