Ultrasound as a useful imaging modality for tumor detection and staging

This paper represents an overview of the uses of ultrasound in tumor detection and staging. This modality can detect and define the etiology of a mass and is helpful in staging the neoplasm and in streamlining the diagnostic and/or staging workup. Often a mass can be localized and biopsied or aspirated, leading to prompt diagnosis and treatment. In addition, ultrasound may be used in following tumor progression or regression with treatment as well as secondary effects such as hydronephrosis.
