Defination / Uses
The adrenal flop calculator estimates adrenal flop using anon-contrast checkup, a discrepancy- enhanced checkup with a detention of 60-75 seconds, and a delayed checkup at 15 twinkles. We use it originally to diagnose adrenal adenoma.
Adenomas (both lipid-rich and lipid-poor) swiftly wash out distinction, whereas non-adenomas (e.g, metastases) generally enhance snappily but take longer to washout. Therefore, you can use the adrenal bomb formula to distinguish adrenal adenomas from non-adenomas.
Adrenal washout protocol consists of three elements:
- A non-contrast scan
- A contrast-enhanced scan with a delay of 60-75 seconds
- A delayed scan at 15 minutes
