[Evaluation of transrectal power-Doppler ultrasonography and effect of contrast-enhancement for detecting prostate cancer].
PURPOSE There are many reports about the usefulness of transrectal power-Doppler ultrasonography (PDUS) for detecting prostate cancer because of the high microvessel density in cancerous tissue in the prostate. The purpose of this study was to assess the role of PDUS and contrast-enhanced transrectal power-Doppler ultrasonography (enhanced PDUS) in the identification of prostate cancer. MATER...
متن کاملLaparoscopic colon resection with intraoperative polyp localisation with high resolution ultrasonography coupled with colour power Doppler.
A 40-year-old woman with a 3 cm sigmoid polyp lesion who underwent a laparoscopic colon resection after intraoperative localisation of the lesion using laparoscopic ultrasonography coupled with colour power Doppler is described. She has successful intraoperative detection of the polyp followed by radical laparoscopic removal of the lesion. The advantage of using laparoscopic high resolution ult...
متن کاملContrast-Enhanced Endoscopic Ultrasonography for Pancreatic Tumors
OBJECTIVES To investigate the usefulness of contrast-enhanced endoscopic ultrasonography (CE-EUS) for histological differentiation of pancreatic tumors. METHODS CE-EUS was performed for consecutive patients having a pancreatic solid lesion, and tumors were classified into three vascular patterns (hypervascular, isovascular, and hypovascular) at two time phases (early-phase and late-phase). Co...
متن کاملThe Value of Touch Preparation for Rapid Diagnosis of Brain Tumors as an Intraoperative Consultation
Background: The touch preparation technique is an accurate and rapid method, and when used as intraoperative consultation examination technique it preserves a good amount of tissue for paraffin embedded sections. This study aimed at examining the accuracy of the touch preparation technique by comparing its diagnosis with that of final pathological diagnosis made by microscopic examinations. ...
متن کاملContrast-enhanced color Doppler ultrasonography increases diagnostic accuracy for soft tissue tumors.
Resolution of ultrasonography (US) has undergone marked development. Additionally, a new-generation contrast medium (Sonazoid) used for US is newly available. Contrast-enhanced US has been widely used for evaluating several types of cancer. In the present study, we evaluated the ability of color Doppler US (CDUS) and Sonazoid to differentiate between benign and malignant soft tissue tumors. A t...
