Received January 2007 Accepted July 2007 INTRODUCTION Percutaneous kidney biopsy is most frequently performed under the guidance of ultrasounography or computed tomography (CT).(1) In some patients, however, other options for kidney biopsy should be resorted to in order to obtain an adequate specimen. We hereby describe the technique of fluoroscopy-guided percutaneous needle biopsy of the kidne...

BACKGROUND The purpose of this retrospective study was to compare the results and complication rate in CT guided percutaneous trans-thoracic fine needle aspiration biopsies (FNAB) and core biopsies of lung lesions, and to determine the applicability of these needles. PATIENTS AND METHODS In 242 patients (166 males; 76 females) with mean age of 58.9 years (13-84 years) CT guided biopsies of lu...

This paper reports a novel remotely actuated device for transrectal prostate biopsy, designed for use in a conventional high-field MRI scanner. The device provides three-dimensional MRI guided biopsy needle placement with sub-millimeter accuracy under physician control. Its compact size enables use in both closed and open configuration MRI scanners. Preliminary in-vivo canine experiments demons...

INTRODUCTION Most patients referred for lung biopsy have a focal lesion that is likely to be a carcinoma and fine needle aspiration (FNA) is usually sufficient to confirm diagnosis. Percutaneous cutting needle biopsy (CNB) is an important and potential diagnostic technique when non carcinomatous disease is suspected or when the pulmonary disease is unclear, so tissue architecture is very import...

The aim of the present study was to investigate whether imprint cytology can improve the diagnostic accuracy of computed tomography-guided transthoracic core biopsy. Between October 1997 and June 2004, thoracic lesions in 622 patients underwent biopsy using 19-gauge coaxial guiding needles and 20-gauge biopsy needles under computed tomography guidance. Touch imprint cytology and histopathology ...

Primary adrenal leiomyosarcoma has been reported previously in 25 patients. The patient presented herein is the only case where the definitive diagnosis was made with core needle biopsy evaluation. A 45-year-old male presented with pain in the back and right groin. Radiological evaluation demonstrated a heterogeneous 11 cm right adrenal mass, multiple liver masses, and an enlarged aortocaval ly...
