State-of-the-art CT and MRI of the adrenal gland.

Both CT and MRI have achieved high accuracy in the investigation of patients suspected of having adrenal pathology. The choice of technique will depend on several factors discussed in the review. The advent of spiral CT has allowed the examination to be tailored to demonstrating the adrenal with very high spatial resolution and it remains the most widely used initial technique. This review concentrates on new techniques for evaluating the incidentally discovered adrenal mass and differentiating between adrenal adenomas and metastases.
