[Value of ultrasono-portography using SonoVue in selective portal vein embolization].

Objective: To explore the value of ultrasono-portography using SonoVue in selective portal vein embolization (SPVE).

Methods: Twenty-eight patients with malignant liver tumors underwent percutaneous ultrasound-guided SPVE. The procedure was performed under color Doppler ultrasound guidance in 11 cases (conventional group) and under guidance with ultrasono-portography using SonoVue in 17 cases (contrast group).

Clinical value of contrast-enhanced ultrasonography in the characterization of focal liver lesions: a prospective multicenter trial.

Background: Contrast-enhanced ultrasonography (CEUS) is increasingly accepted in clinical settings for diagnostic imaging of focal liver lesions (FLLs). This study aimed to assess the efficacy of CEUS in the characterization of FLLs in comparison with final diagnosis based on gold standard assessment.

Methods: The study was approved by the local ethics committee and participating patients provided written informed consent.

[Comparative study of endoluminal ultrasonography and spiral computed tomography in preoperative staging of rectal carcinoma].

Objective: To compare the efficacy of endoluminal ultrasonography (EUS) and spiral computed tomography (SCT) in preoperative staging of rectal carcinoma.

Methods: Both EUS and SCT were performed prior to surgery in 68 patients with rectal carcinoma. After radical surgery, the preoperative findings were compared with histologic findings of the operative specimens, and the efficacy of EUS and SCT in staging the rectal carcinoma were evaluated.
