conclusion according to the results of our series, percutaneous liver biopsy using the tru-cut biopsy gun guided by ultrasonography can be performed safely. we resolve that routine ultrasound of the puncture site is a quick, effective and safe procedure. the complication rate is very low. the us-assisted percutaneous liver biopsy should be used for all cases. results a total of 1018 patients we...

PURPOSE To evaluate therapeutic efficacy of ultrasound (US)-guided high-intensity focused ultrasound (HIFU) ablation for treatment of needle-track seeding of hepatocellular carcinoma (HCC). MATERIALS AND METHODS Nine patients with needle-track seeding of HCC were treated as outpatients using US-guided HIFU ablation. The mean size of the lesion was 1.8 cm (range 1.1 to 2.6 cm), two lesions wer...

OBJECTIVE To evaluate whether the removal of an intraductal mass using an ultrasound (US)-guided directional vacuum-assisted device can eliminate symptoms in patients presenting with abnormal nipple discharge. MATERIALS AND METHODS Between March 2004 and October 2006, 36 patients who presented with abnormal nipple discharge, underwent US-guided, 11-gauge vacuum-assisted biopsy for a benign in...

INTRODUCTION 15-30% of patients with lung cancer will have supraclavicular and cervical lymphadenopathy (SCLN). Ultrasound (US)-guided fine-needle aspiration (FNA) cytology is regarded as an effective diagnostic tool in small size lymph nodes (LNs) and impalpable positron emission tomography detected nodes. We evaluated our diagnostic service performance in relation to the adequacy of samples f...

When performing CT-guided procedures or angiographic procedures, radiologists performing procedures need to communicate with radiographers at a workstation behind radiation shielding glass. As shielding renders verbal communication impossible, we have developed a set of standardised hand signals for use at our department to help us achieve clear and efficient communication between radiologists ...

Dr MacLennan is a Specialist Anaesthetist at Auckland City Hospital His clinical interests include ultrasound guided regional anaesthesia, cardiac evaluation for non cardiac surgery, anaesthesia for vascular surgery and liver transplantation. He is currently conducting a prospective audit of the saftey and efficacy of ultrasounded (US) guided nerve blocks and has runs frequent ultrasound worksh...

BACKGROUND Extent of lymph node involvement in patients with non-small cell lung cancer (NSCLC) is the cornerstone of staging and influences both multimodality treatment and final outcome. The aim of this study was to investigate accuracy and characteristics of intraoperative ultrasound guided systematic mediastinal nodal dissection in patients with resected NSCLC. METHODS From January 2008 t...

Accurate lymph node characterization is important in a large number of clinical settings. We evaluated the usefulness of Contrast Enhanced Ultrasound (CEUS) in distinguishing between benign and malignant lymph nodes compared with conventional ultrasonography in the differential diagnosis of superficial lymphadenopathy.We present our experience for 111 patients enrolled in a single center.111 su...

Successful regional anaesthesia can be summed up by the axiom “The right drug, in the right dose, in the right place”.1 The process of getting the drug to the right place has evolved from the routine elicitation of paraesthesia, to the use of peripheral nerve stimulation, and most recently, ultrasound (US) guidance. US guidance has revolutionised regional anaesthesia (or more specifically, peri...
