One of the simplest quantitative signal methods is to determine the percentage of signal drop relative to the lesion’s signal intensity on the in-phase images. This is referred to as the ASII.
WebCT, MRI, and PET readily characterize many benign adrenal lesions from their characteristic diagnostic imaging features, including lipid-poor adenomas that can be identified by washout techniques and PET. A small minority of adrenal masses, however, remain indeterminate after imaging.
