Short-term evaluation of liver tumors after transarterial chemoembolization: limitations and feasibility of contrast-enhanced ultrasonography.

Purpose: To evaluate the limitations and the feasibility of contrast-enhanced ultrasonography (CEUS) for the assessment of tumor response shortly after transarterial chemoembolization (TACE).

Materials And Methods: Fifty seven patients (41 patients with hepatomas, 16 patients with metastases) were studied with CEUS before, 1 day after, and 30 days after TACE. A CEUS-efficiency score (CEUS-ES) was calculated, which evaluated: (a) the completeness of visualization of the target tumor(s) (2: good, 1: adequate, 0: poor) and (b) the quality of delineation of post-TACE necroses (2: good, 1: adequate, 0: poor).

Unenhanced and contrast-enhanced ultrasonography during hepatic transarterial embolization and chemoembolization with drug-eluting beads.

The purpose of this study was to describe and evaluate the findings of unenhanced ultrasonography (US) and contrast-enhanced ultrasonography (CEUS) when these modalities are applied during transarterial embolization (TAE) or transarterial chemoembolization (TACE) of liver tumors. Sixteen tumors (9 hepatocellular carcinomas, 5 metastases from colorectal cancer, and 2 hemangiomas) were treated with TAE with microspheres and/or TACE with drug-eluting beads. All of these lesions were studied with intraprocedural unenhanced US and 12 were studied with intraprocedural CEUS.

Contrast-enhanced ultrasonography of hepatocellular carcinoma after chemoembolisation using drug-eluting beads: a pilot study focused on sustained tumor necrosis.

The purpose of this study was to assess the use of contrast-enhanced ultrasonography (CEUS) and the sustained antitumor effect of drug-eluting beads used for transarterial chemoembolisation (TACE) of unresectable hepatocellular carcinoma (HCC). Ten patients with solitary, unresectable HCC underwent CEUS before, 2 days after, and 35 to 40 days after TACE using a standard dose (4 ml) of drug-eluting beads (DC Beads; Biocompatibles, Surrey, UK) preloaded with doxorubicin (25 mg doxorubicin/ml hydrated beads). For CEUS, a second-generation contrast agent (SonoVue, Bracco, Milan, Italy) and a low mechanical-index technique were used.

Imaging of the acute scrotum: is there a place for contrast-enhanced ultrasonography?

Purpose: To present and evaluate the findings of contrast-enhanced ultrasonography (CEUS) in typical cases of acute painful scrotum.

Materials And Methods: Nineteen patients aged from 19 to 61 years old were included in the study. All patients underwent grey-scale and color Doppler ultrasonography (US) of the scrotum, followed by imaging after i.

Findings and limitations of focused ultrasound as a possible screening test in stable adult patients with blunt abdominal trauma: a Greek study.

Our objective is to underline the place of FAST (focus assessment by sonography for trauma) ultrasonography (US) in the investigation of blunt abdominal trauma. We retrospectively examined the ultrasound findings in 1,999 haemodynamically stable adult patients. These people were admitted to the emergency room (ER) for possible blunt abdominal trauma.
