Three-dimensional angiography for CT-guided stereotactic procedures: a new system.
A new CT-guided stereotactic system using tridimensional angiography is described. The trajectory is directly determined from a moving probe ('floating line') which appears on a tridimensional stereoscopic angiography, permitting the choice of an avascular trajectory with a high degree of accuracy. The authors have done 84 probe implantations with an excellent diagnostic and therapeutic rate and no morbidity-mortality.
