چکیده
PSs placed by a spinal surgical fellow (SSF) without prior experience under Attending Spinal Consultant (ASC) supervision from two tertiary spinal centers in Australia were investigated. All patients had postoperative radiographic studies, X-ray (XR) and/or computed tomography (CT), which were graded by two blinded and independent observers. Screws were graded as “acceptable” (contained within the pedicle or <30% screw diameter breach of the pedicle or vertebral body) and “misplaced” (>30% screw diameter outside the pedicle/vertebral body). For XR, this was denoted as XR1 and XR2, respectively. The same was used for CT; however, CT1 was subdivided Key perspectives on the learning curve of pedicle screw placement, stereotactic radiosurgery for brain metastases, growth of incidentally found meningiomas, and the Barrow Ruptured Aneurysm Trial

Stereotactic radiosurgery for intracranial meningiomas: current concepts and future perspectives.
Meningiomas are among the most common adult brain tumors. Although the optimal management of meningiomas would provide complete elimination of the lesion, this cannot always be accomplished safely through resection. Therefore, other therapeutic modalities, such as stereotactic radiosurgery (as primary or adjunctive therapy), have emerged. In the current review, we have provided an overview of t...
متن کاملA deep convolutional neural network-based automatic delineation strategy for multiple brain metastases stereotactic radiosurgery
Accurate and automatic brain metastases target delineation is a key step for efficient and effective stereotactic radiosurgery (SRS) treatment planning. In this work, we developed a deep learning convolutional neural network (CNN) algorithm for segmenting brain metastases on contrast-enhanced T1-weighted magnetic resonance imaging (MRI) datasets. We integrated the CNN-based algorithm into an au...
متن کاملStereotactic radiosurgery as single-modality treatment of incidentally identified renal cell carcinoma brain metastases.
BACKGROUND Initial staging evaluation of patients with renal cell carcinoma (RCC) has led increasingly to the diagnosis of brain metastases in patients who are otherwise neurologically asymptomatic. We present our experience treating patients with incidentally identified brain metastases with initial stereotactic radiosurgery (SRS) monotherapy and compare outcomes with those of patients treated...
متن کاملDevelopment of A Head Docking Device for Linac-based Stereotactic Radiosurgery System to be Installed on Neptun 10 PC Linac
Introduction: Stereotactic radiosurgery is a technique for the treatment of intracranial lesions with highly collimated x-ray beam. Linac-based radiosurgery is currently performed by two techniques: couch or pedestal mounted. In the first technique, a device is required to affix patient's head to a couch and moreover to translate it accurately. Structure of suc...
