ABSTRACT Deep brain stimulation (DBS) has become a routine therapy for Parkinson's disease. Standard CT imaging, often used to evaluate DBS electrodes in patients with limited benefit or significant side effects, has limitations including inability to distinguish different metallic components of the DBS lead. CT imaging with an extended Hounsfield unit (EHU) scale allows advanced image processing techniques to detect individual electrodes. EHU-CT may be co-registered to MRI volumes to provide accurate anatomical visualization of DBS lead contacts.

    ABSTRACT: BACKGROUND:: Accurate localization of the subthalamic nucleus (STN) is critical to the success of deep brain stimulation (DBS) surgery for Parkinson's disease (PD). Recent developments in high field strength magnetic resonance imaging (MRI) have made it possible to visualize the STN in greater detail. However, the relationship of the MR-visualized STN to the anatomic, electrophysiological, or atlas-predicted STN remains controversial. OBJECTIVE:: To evaluate the size of the STN visualized on 3T MRI compared to anatomic measurements in cadaver studies, and to compare the predictions of 3T MRI to those of the Schaltenbrand-Wahren (SW) atlas for intraoperative STN microelectrode recordings (MER). METHODS:: We evaluated the STN by 3T MRI and intraoperative MER in twenty PD patients undergoing DBS surgery. We compared our findings to anatomic cadaver studies and to the individually scaled SW-atlas based predictions for each patient. RESULTS:: The dimensions of the 3T MR-visualized STN were very similar to those of the largest anatomic study (MRI length, width, and height: 9.8 ± 1.6 mm, 11.5 ± 1.6 mm, and 3.7 ± 0.7 mm, n = 40; cadaver length, width, and height: 9.3 ± 0.7 mm, 10.6 ± 0.9 mm, and 3.1 ± 0.5 mm, n = 100). The amount of STN traversed during intraoperative MER recording was better correlated to the 3T MR-visualized STN than the SW-atlas predicted STN (R = 0.38 versus R = -0.17). CONCLUSION:: The STN as visualized on 3T MRI corresponds well with cadaveric anatomical studies and intraoperative electrophysiology. STN visualization with 3T MRI may be an improvement over SW-atlas-based localization for STN DBS surgery in PD.

    ABSTRACT: Where no society-based or manufacturer guidance on radiation limits to neuromodulation devices is available, this research provides the groundwork for neurosurgeons and radiation oncologists who rely on the computerized treatment plan clinically for cancer patients. The focus of the article is to characterize radiation parameters of attenuation and scatter when an incident therapeutic x-ray beam is directed upon them. At the time of this writing, manufacturers of Neuromodulation products do not recommend direct exposure of the device in the beam nor provide guidance for the maximum dose for these devices.

    ABSTRACT: Deep brain stimulation (DBS) of the subthalamic nucleus (STN) in particular is highly effective in relieving symptoms of Parkinson's disease (PD). However, it can also have marked psychiatric side effects, including delirium, mania, and psychosis. The etiologies of those effects are not well-understood, and both surgeons and consulting psychiatrists are in need of treatment strategies. Two patients with young onset of PD and without significant prior psychiatric problems presented for bilateral STN DBS when medications became ineffective. Both had uneventful operative courses but developed florid psychosis 1-2 weeks later, before stimulator activation. Neither showed signs of delirium, but both required hospitalization, and one required treatment with a first-generation antipsychotic drug. Use of that drug did not worsen PD symptoms, contrary to usual expectations. These cases describe a previously unreported post-DBS syndrome in which local tissue reaction to lead implantation produces psychosis even without electrical stimulation of subcortical circuits. The lesion effect also appears to have anti-Parkinsonian effects that may allow the safe use of otherwise contraindicated medications. These cases have implications for management of PD DBS patients postoperatively, and may also be relevant as DBS is further used in other brain regions to treat behavioral disorders.
