Contrast-enhanced ultrasound diagnoses small renal lesions
June 03, 2008
Solid renal parenchymal lesions with a diameter of 5 cm or less can be difficult to diagnose, requiring irradiation and biopsy. Catching renal cell carcinoma in early stages before tumors grow larger than 7 cm, however, increases a patient’s chances of survival over five years. Researchers in China have found that contrast-enhanced ultrasound can accurately diagnose these small lesions.
