1.5T Intraoperative MR Imaging in Craniopharyngiomas

September 21, 2010 updated by: Hofmann, Bernd, M.D.

Intraoperative Use of a MR Tomography System Combined With Neuronavigation - Analysis of the Craniopharyngioma Subgroup ("Intraoperative Nutzung Eines Kernspintomographie-Systems in Direkter Kopplung Mit Einem Neuronavigations-System")

Purpose of this study is to investigate whether intraoperative imaging using a 1.5T MRI in craniopharyngioma surgery is useful in order to increase the rate of complete tumor removal.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Rate of additional tumor removal
Time Frame: up to 3-4 months following surgery
Number of patients in whom non suspected tumor remants were indicated by intraoperative MRI and remnants could be removed completely thereafter. Results have to be confirmed in 1st follow up imaging.
up to 3-4 months following surgery
Rate of achievement of intended extent of removal
Time Frame: up to three months following surgery
It is examined whether the extent of tumor removal defined prior to surgery was achieved
up to three months following surgery
Diagnostic reliability
Time Frame: within 3 -4 months following surgery
false positive or negative interpretation of intraoperative imaging determined after follow-up imaging 3 - 4 months following surgery
within 3 -4 months following surgery

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Surgical complication
Time Frame: within 1st week following surgery
Rate of new deficits following surgery (excluding new endocrine deficits)
within 1st week following surgery
