title: [Non vascular interventional radiology--general].
abstract: Since last about 20 years, invasive diagnostic procedures have gradually changed the conception to interventional radiology (IVR). Non vascular IVR has been developing steadily by suitable instruments and excellent techniques as well as vascular IVR. The fields of non-vascular IVR is becoming wider and wider in various regions in the body. Non-vascular IVR contains many kinds of drainage and forming inner fistula in the biliary and urinary tracts, for example, occlusive jaundice or hydronephrosis. Drainage for abscess in the thoracic or abdominal cavity is a good indication except peri-pancreatic abscess. In addition, IVR means time saving and cost saving in the aspiration biopsy for malignant neoplasms this is fast decision for reasonable therapies. In the earlier period, aspiration biopsy was considered as dangerous method because of bleeding and dissemination of malignant seeds along the route of aspiration needles. By using fluoroscopic image amplifier and ultrasonic unit, non-vascular IVR has many indications that radiologist's specialty demonstrated. Therefore, radiologist should have heavy responsibility based on understanding of right knowledge and good management for non-vascular IVR.
