Abstract
Disclosed is a CT and MRI synchronous detection positioning needle. The needle comprises a silicone tube which is internally provided with a guide needle; the two sides of the guide needle are provided with hollow cavities; each hollow cavity is internally provided with membranes dividing the hollow cavity into a plurality of small chambers which are filled with liquid, wherein a CT contrast agent is filled in a plurality of small chambers at one side of the guide needle, and an MRI contrast agent is filled in a plurality of small chambers at the other side of the guide needle. In the invention, specially designed silicone positioning needles are implanted in vivo, and synchronous comparison of different image data and pathological data is implemented by means of multi-plane reconstruction technology, so the CT and MRI synchronous detection positioning needle can be widely applied to experimental study on tumors.
