چکیده
Percutaneous intraspinal navigation (PIN) is a new minimally invasive approach to the CNS. The authors studied the utility of MR-guided intracranial navigation following access to the subarachnoid compartment via PIN. The passive tracking technique was employed to visualize devices during intracranial navigation. Under steady-state free precession (SSFP) MR-guidance a microcatheter-microguidewire was successfully navigated to multiple brain foci in two cadavers. SSFP MR fluoroscopy possesses adequate contrast and temporal resolution to allow MR-guided intracranial navigation.

Hyperacute subarachnoid hemorrhage on T2-weighted MR images.
We describe a case of hyperacute subarachnoid and intraventricular hemorrhage from a ruptured aneurysm, which occurred while the patient was undergoing MR imaging. Compared with CSF, the blood in the subarachnoid space had slightly lower signal intensity on T2*-weighted gradient-echo images and increased signal intensity on T2-weighted spin-echo images. This finding differs from the generally a...
متن کاملInterventional MR imaging with an endospinal imaging coil: preliminary results with anatomic imaging of the canine and cadaver spinal cord.
Percutaneous intraspinal navigation (PIN) is a new minimally invasive approach to the subarachnoid space. Using conventional radiographic fluoroscopy, entrance is gained to the lumbar subarachnoid space, allowing navigation throughout the spinal canal. Using an antenna/guidewire introduced via PIN, we performed endospinal MR imaging of the thoracic spinal cord in a cadaver and canine subject. C...
متن کاملDecreased diameter of the optic nerve sheath associated with CSF hypovolemia.
The subarachnoid space around the optic nerve can be detected by fat-saturated T2-weighted MR imaging of the orbit, and dilation of this space reflects increased intracranial pressure. We examined 3 patients with CSF hypovolemia with MR imaging of the orbit and measured the optic nerve sheath diameter before and after treatment. We showed that the subarachnoid space is decreased in patients wit...
متن کاملMR of cranial and spinal meningeal carcinomatosis: comparison with CT and myelography.
Thirty-nine patients with histologically proved primary neoplasms, focal neurologic deficits, and positive CSF cytology were evaluated by enhanced cranial CT and MR, or complete myelography and MR of the spine. Intracranial abnormalities were noted on CT in 56% of cases and included abnormal enhancement of subarachnoid space and ventricular walls, ventricular dilatation, obliteration of cortica...
متن کاملWE-G-WAB-01: Real-Time Catheter Tracking and Visualization in MR-Guided Brachytherapy.
PURPOSE The challenge of catheter-tip visualization for interstitial needle placement in gynecologic brachytherapy remains unmet. We evaluate an approach to actively track tip locations and visualize catheter trajectories and surrounding soft-tissue in real-time during an intervention. The methods include development of clinical needles with magnetic resonance (MR) tracked microcoils, an MR tra...
