Neuroradiology: the Minimally Invasive Therapy LiTT
1. What is LiTT?
LiTT is a minimally invasive treatment approach that uses laser heat to destroy abnormal tissue. The procedure is guided by MRI to ensure that the treatment is precisely targeted to the lesion.
2. In which cases can it be applied?
The method is mainly used in selected cases of epilepsy, brain tumors and radiation necrosis after radiation therapy for tumors.
3. What is the role of imaging in this treatment?
Imaging is of central importance. MRI is used both for the precise planning of the insertion of the laser catheter and for monitoring the temperature rise in the brain tissue during the treatment, aiming for maximum accuracy and protection of healthy structures.
4. What advantages does it offer over open surgery?
Compared to surgery, LiTT is usually associated with a significantly smaller incision, less postoperative pain, shorter hospitalization, and faster return to daily activities. For many patients, this translates into a more positive treatment experience.
5. How long does the procedure take and what happens next?
The procedure usually takes 1-2 hours and is performed under general anesthesia in an MRI scanner. After treatment, the patient remains in the hospital for 1-2 nights for monitoring.
6. Is it suitable for all patients?
No. Patients are selected very carefully, after an evaluation with history and imaging tests, as well as a discussion with the other treating physicians. This is a form of treatment that is part of the concept of personalized medicine.
7. The Role of the Neuroradiologist in LiTT Treatment.
The role of the Neuroradiologist is crucial in LiTT. Initially, in the planning with precise mapping of the lesion for the placement of the laser catheter, and primarily in the execution and monitoring of the effectiveness of the treatment in real time with the use of imaging.
