Background: Endovascular therapy for acute ischemic stroke has revolutionized clinical care for patients with stroke and large vessel occlusion, but treatment remains time sensitive. At our stroke center, up to half of the door-to-groin time is accounted for after the patient arrives in the angio-suite. Here, we apply the concept of a highly visible timer in the angio-suite to quantify the impact on endovascular treatment time.

Background: Intrathecal nusinersen is the first Food and Drug Administration-approved treatment for spinal muscular atrophy. Reliable intrathecal access is critical for initial and maintenance therapy; however, this can be challenging in older patients with spinal muscular atrophy many of whom have had prior lumbar instrumentation and osseous fusion. Transforaminal lumbar punctures have emerged as a technique for intrathecal access that avoids the hazards of cervical punctures.

Purpose: Despite standard of care (SOC) established by Stupp, glioblastoma remains a uniformly poor prognosis. We evaluated IGV-001, which combines autologous glioblastoma tumor cells and an antisense oligonucleotide against IGF type 1 receptor (IMV-001), in newly diagnosed glioblastoma.

Patients And Methods: This open-label protocol was approved by the Institutional Review Board at Thomas Jefferson University.

Purpose: The vessel wall MR imaging (VWI) literature was systematically reviewed to assess the criteria and measurement methods of VWI-related imaging endpoints for symptomatic intracranial plaque in patients with ischemic events.

Methods: PubMed, Scopus, Web of Science, EMBASE, and Cochrane databases were searched up to October 2019. Two independent reviewers extracted data from 47 studies.

Diagnosis of intracranial arterial dissections can be challenging due to the wide spectrum of imaging presentations. High-resolution vessel wall MR imaging can be a useful adjunct to conventional lumen-based imaging techniques for diagnosing arterial dissections. We present a case of a 37-year-old male with a history of a Wolff-Parkinson-White syndrome presenting with acute onset of nausea, vertigo, and left body hemisensory loss of pain and temperature.

Aims: The purpose of our study was to analyze utilization trends and physician specialty distribution in spinal catheter angiography and magnetic resonance angiography in the Medicare fee-for-service population.

Methods: Data from the CMS Physician/Supplier Procedure Summary Master Files for 2004 to 2016 were used for this study. The Current Procedural Terminology version 4 codes for spinal magnetic resonance angiography (72159) and spinal catheter angiography (75705) were used to analyze the volumes of these procedures.

The purpose of this study was to examine the degree to which nonradiologist physicians provide formal interpretations for advanced imaging and to consider whether adequate training can be achieved for those physicians. This investigation assumed that hospitals are the only places where formal imaging training occurs. The CMS Physician/Supplier Procedure Summary Master Files (PSPSMFs) of the Medicare Part B datasets for 2015 were reviewed.

Purpose: To determine the utility of obtaining whole-spine survey MRI after a whole-spine CT diagnoses single level or contiguous fractures.

Methods: A retrospective search from 2015 to 2017 was performed using an institutional PACS database for consecutive patients who sustained spinal fractures from blunt injury. Only patients who received whole-spine CT followed by whole-spine MRI were included in the study.

Objective: The purposes of this study were to document recent trends in stroke intervention at a tertiary-care facility with a comprehensive stroke center and to analyze current procedure volumes and the employment of specialty providers in neurointerventional radiology (NIR).

Materials And Methods: Institutional trends in the volume of mechanical thrombectomy were analyzed on the basis of the number of patients who underwent mechanical thrombectomy from 2013 to 2017. To evaluate the current status of mechanical thrombectomy volumes in the United States, the number of patients in the Medicare fee-for-service database who underwent mechanical thrombectomy in 2016 was assessed.

Objective: Laser interstitial thermal therapy (LITT), a method for ablating brain tissue under real-time MR thermometry, has been used more frequently in recent years to treat nonmalignant lesions. The purpose of this study is to longitudinally characterize MRI features after LITT in patients with drug-resistant epilepsy, primarily in the setting of mesial temporal sclerosis.

Materials And Methods: MR images from 23 consecutive patients who underwent LITT were retrospectively reviewed.

Spinal paragangliomas (SP) are benign and overall rare extra-adrenal neuroendocrine tumors often diagnosed during workup for lower back pain. Complete surgical resection achieves both symptomatic relief and cure. We present a 32-year-old man with a longstanding history of lumbago and bilateral lower extremity pain found to have a lumbar paraganglioma at the level of the L3 vertebrae.

Brain tumors--particularly glioblastoma multiforme--pose an important public health problem in the United States. Despite surgical and medical advances, the prognosis for patients with malignant gliomas remains grim: current therapy is insufficient with nearly universal recurrence. A major reason for this failure is the difficulty of delivering therapeutic agents to the brain: better delivery approaches are needed to improve treatment.
