Contrast-enhanced ultrasound improves diagnosis in some liver cancer cases

March 3, 2008 Contrast-enhanced ultrasound improves diagnosis in some liver cancer cases Wendy Despain -------------------------------------------------------------------------------- Injected contrast improved liver ultrasound sensitivity and specificity in malignant liver lesions, aiding diagnosis in 13.7% of cases in a French study. Researchers concluded that contrast-enhanced ultrasound should be routine practice when considering surgical management of hepatic lesions. Dr. Linda Chami and colleagues at the Institut Gustave Roussy in Villejuif examined 116 patients, first with conventional ultrasound, then with contrast-enhanced ultrasound combined with perfusion software — either vascular recognition or pulse subtraction imaging. Histological results served as the standard for judging sensitivity and specificity for both exams.
