RESUMO
This prospective study was carried out to assess the ability of colour Doppler ultrasound (CDUS) and power flow imaging to differentiate between benign and malignant adrenal masses. We examined 56 adrenal masses, discovered at CT, in 47 patients who had undergone CT for known extraadrenal malignancy or unrelated benign conditions. The nature of the masses was confirmed by histopathology or assessed for likelihood of malignancy by CT appearance, MRI appearance, recent development or increase in size. In none of the adrenal masses was blood flow detected by colour Doppler or power imaging, despite optimizing scanning parameters for the detection of slow flow. We conclude that colour Doppler ultrasound and power imaging do not help in differentiating benign from malignant adrenal masses.

Traditionally used for neurologic indications, magnetic resonance imaging (MRI) is now being used to diagnose the most common musculoskeletal, vascular, hepatic, biliary, adrenal, and renal disorders. Drs Schnitker and Light discuss the nonneurologic indications for MRI as both a primary and an adjunct study. The advantages and disadvantages of fast scanning and open MRI are also presented.
