Multimodal Imaging in Malignant Brain Tumors: Enhancing the Preoperative Risk Evaluation for Motor Deficits with a Combined Hybrid MRI-PET and Navigated Transcranial Magnetic Stimulation Approach

Jeffrey Ross March 5, 2016March 2, 2016 Brain, Editor's Choices

Editor’s Choice Editor’s Comment Patients with malignant brain tumors involving the central region underwent a hybrid O-(2-[18F]fluoroethyl)-L-tyrosine–PET-MR imaging and motor mapping by neuronavigated transcranial magnetic stimulation. The spatial relationship between functional tissue and lesion volumes as depicted by structural and

MR Angiographic–Guided Percutaneous Sclerotherapy for Venous Vascular Malformations: A Radiation Dose-Reduction Strategy

Jeffrey Ross February 27, 2016February 26, 2016 Editor's Choices, Patient Safety

Editor’s Choice Editor’s Comment This case series of 5 patients describes the authors’ approach to using dynamic MRA with direct puncture of venous malformations to define the angioarchitecture and draining veins in these lesions. MultiHance in a 1:100 dilution with

Spine Cryoablation: Pain Palliation and Local Tumor Control for Vertebral Metastases

Jeffrey Ross February 6, 2016January 25, 2016 Editor's Choices, Interventional, Spine

Editor’s Choice Editor’s Comment This is a retrospective study of imaging-guided spine cryoablation that was performed on 31 vertebral metastases in 14 patients. The lesions were refractory to conventional chemoradiation therapy or analgesics and were ablated to achieve pain palliation

3D Printing of Intracranial Aneurysms Using Fused Deposition Modeling Offers Highly Accurate Replications

Jeffrey Ross January 30, 2016January 25, 2016 Editor's Choices, Interventional

Editor’s Choice Editor’s Comment The authors evaluated fused deposition modeling for the production of aneurysm models replicating patient-specific anatomy using 3D rotational angiographic data from 10 patients. A hollow model with connectors for silicone tubes was fabricated by using acrylonitrile

Presurgical Assessment of the Sensorimotor Cortex Using Resting-State fMRI

Jeffrey Ross January 25, 2016January 25, 2016 Editor's Choices, Functional

Editor’s Choice Editor’s Comment Task-based approaches to functional localization of the motor cortex have limitations such as long scanning times and exclusion of patients with severe functional or neurologic disabilities and children. Resting-state fMRI may avoid these difficulties because patients

Bone-Subtracted Spinal CT Angiography Using Nonrigid Registration for Better Visualization of Arterial Feeders in Spinal Arteriovenous Fistulas

Jeffrey Ross January 9, 2016December 24, 2015 Editor's Choices, Interventional, Spine

Editor’s Choice Editor’s Comment CTA images of the arterial and late arterial phases were used to obtain warped images of the late arterial phase by nonrigid registration that was adjusted to the arterial phase images. R-CTA images were then obtained

Responses of the Human Brain to Mild Dehydration and Rehydration Explored In Vivo by 1H-MR Imaging and Spectroscopy

Jeffrey Ross January 2, 2016December 31, 2015 Brain, Editor's Choices

Editor’s Choice Editor’s Comment Serial T1WI and 1H-MR spectroscopy data were acquired in 15 healthy individuals at normohydration, at 12 hours of dehydration, and during 1 hour of oral rehydration. Osmotic challenges were monitored by serum measures, including osmolality and

Diagnostic Accuracy of PET, SPECT, and Arterial Spin-Labeling in Differentiating Tumor Recurrence from Necrosis in Cerebral Metastasis after Stereotactic Radiosurgery

Jeffrey Ross December 26, 2015December 24, 2015 Brain, Editor's Choices

Editor’s Choice Editor’s Comment The authors retrospectively reviewed patients treated between 2007–2010 and identified 14 patients with cerebral metastasis who had clinical or radiographic progression following stereotactic radiosurgery and were imaged with arterial spin-labeling (ASL), FDG-PET, and thallium SPECT before

The Contribution of Common Surgically Implanted Hardware to Functional MR Imaging Artifacts

Jeffrey Ross December 5, 2015November 20, 2015 Editor's Choices, Functional

Editor’s Choice Editor’s Comment The authors calculated the BOLD-dependent MR imaging artifact impact arising from surgically implanted hardware through a retrospective analysis of fMRIs acquired from 2006–2014. Mean artifact volume associated with intracranial hardware was 4.3 cubic centimeters. The mean

Ultra-High-Field MRI Visualization of Cortical Multiple Sclerosis Lesions with T2 and T2*: A Postmortem MRI and Histopathology Study

Jeffrey Ross November 28, 2015November 20, 2015 Brain, Editor's Choices

Editor’s Choice Editor’s Comment At 7T, 2D multiecho spin-echo T2WI and 3D gradient-echo T2*WI were acquired from 27 formalin-fixed coronal hemispheric brain sections of 15 patients and 4 healthy controls. Proteolipid-stained tissue sections were matched to the corresponding MR images,
