Trans-reservoiral ventriculography (TRV).

We report here the usefulness of ventriculography by means of percutaneous injection of a recently developed water-soluble contrast medium of great safety through a shunt flushing reservoir; the method is called trans-reservoiral ventriculography (TRV), and is presented here in twelve clinical cases. The TRV is especially useful in observing the course of brain tumour after either surgical or non-surgical treatment.
