title: Needle biopsy of intrancranial lesions guided by computerized tomography.
abstract: Biopsies can be performed directly with computerized tomography (CT) head scanners with some difficulty. The small scanning orifice does not allow enough room for needle placement; therefore, biopsy is difficult. In contrast, the scanning orifice of the CT body scanner is large enough to permit biopsies without hindrance. Over 300 CT-guided abdominal biopsy procedures have been performed at the Cleveland Clinic Foundation. We are reporting the technique and the results of 14 CT-guided brain biopsies. There were no complications in the series and an accurate diagnosis was made for 13 of the 14 patients.
