Core needle biopsy represents a safe and cheap alternative diagnostic method to open biopsy and fine-needle aspiration cytology in head and neck tumors. There is little evidence in the literature about the use of core needle biopsy in minor salivary gland lesions. This single case report presents a 60-year-old woman with a painless swelling in the soft palate, breathing and swallowing difficult...

The aim of this study was to compare accuracy of an image guided percutaneous core needle biopsy (PCNB), using ultrasound or computed tomography, to PCNB without image guidance in the diagnosis of palpable soft tissue tumours. One hundred forty patients with a suspected soft tissue sarcoma underwent a percutaneous core needle biopsy with or without image guidance. One hundred eleven patients ha...

Purpose: To report our experience with computed tomography (CT)-guided coaxial needle biopsy of intrathoracic lesions by different approaches. Material methods: Medical records of 100 patients who underwent CT-guided biopsy of intrathoracic lesions were evaluated retrospectively. A coaxial needle technique was used in all patients; an 18-gauge needle was used for transsternal penetration, throu...

We performed a prospective study of sixty-two patients who were managed with a closed core needle biopsy in an outpatient clinic for a soft-tissue mass or a bone tumor with soft-tissue extension between August 1, 1992, and June 1, 1994. Eight (13 percent) of the closed core needle biopsies yielded no neoplastic tissue. Two needle biopsies (3 percent), which were of myxomatous masses, did not al...

OBJECTIVE The aim of this study was to compare the use of semi-automated (Medax Velox 2; Poggio Rusco, Italy) and automated (Bard Magnum Biopsy Instrument; Covington, GA, USA) core biopsy needles, for ultrasound guided breast biopsy. MATERIALS AND METHODS A 14G semi-automatic spring loaded core biopsy needle with a 22-mm-throw (Medax Velox 2; Poggio Rusco, Italy) and 14-gauge automated needle...

OBJECTIVE To evaluate the in vivo efficiency of the biopsy tract radiofrequency ablation for hemostasis after core biopsy of the liver in a porcine liver model, including situations with bleeding tendency and a larger (16-gauge) core needle. MATERIALS AND METHODS A preliminary study was performed using one pig to determine optimal ablation parameters. For the main experiment, four pigs were a...
