This study compared two methods used to guide needle biopsies of suspicious lumps (lesions) in the liver. A biopsy is a procedure where a small sample of tissue is taken to make a diagnosis. Doctors often use standard ultrasound (US) to see the lesion and guide the needle. Another method uses a special dye (contrast agent) injected into a vein during the ultrasound, which is called contrast-enhanced ultrasound (CEUS). The dye helps blood vessels and the lesion "light up" on the screen. The researchers wanted to find out if using CEUS leads to a more successful biopsy than using standard US alone.
