CT立体定向术是近十几年来发展起来的一门新兴技术。颅内占位性病变应用CT、MRI等检查手段,虽然能显示病变位置、大小和形状,但对病变定性诊断尚有不足。对深在浸润性生长的病变或由于解剖关系所限不能切除的病变,CT导向活检可作为选择治疗的重要参考。我院于1986年开展此项工作,至1993年在CT导向下已对36例颅内病变者进行活检,结果介绍如下。 Stereotactic CT is a new technology developed in recent ten years. Intracranial space-occupying lesions using CT, MRI and other inspection methods, although the location, size and shape of lesions can be displayed, but the qualitative diagnosis of the disease is still inadequate. CT-guided biopsy can be an important reference for the selection of treatment of deep invasive growth lesions or unresectable lesions due to anatomic relationships. Our hospital in 1986 to carry out this work, in 1993 under the guidance of CT has been 36 cases of intracranial lesions biopsy, the results are described below.
