Frontal and anterior temporal hypometabolism post chemoradiation in head and neck cancer: A real-world PET study J. Neuroimaging (IF 2.4) Pub Date : 2023-12-26 Steven Bishay, W. Hudson Robb, Trent M. Schwartz, David S. Smith, Lok Hin Lee, Cynthia J. Lynn, Tammy L. Clark, Angela L. Jefferson, Jeremy L. Warner, Eben L. Rosenthal, Barbara A. Murphy, Timothy J. Hohman, Mary Ellen I. Koran
Adverse neurological effects after cancer therapy are common, but biomarkers to diagnose, monitor, or risk stratify patients are still not validated or used clinically. An accessible imaging method, such as fluorodeoxyglucose positron emission tomography (FDG PET) of the brain, could meet this gap and serve as a biomarker for functional brain changes. We utilized FDG PET to evaluate which brain regions

Redefining CT perfusion-based ischemic core estimates for the ghost core in early time window stroke J. Neuroimaging (IF 2.4) Pub Date : 2023-12-25 Manisha Koneru, Meisam Hoseinyazdi, Dhairya A. Lakhani, Cynthia Greene, Karen Copeland, Richard Wang, Risheng Xu, Licia Luna, Justin M. Caplan, Adam A. Dmytriw, Adrien Guenego, Jeremy J. Heit, Gregory W. Albers, Max Wintermark, Luis F. Gonzalez, Victor C. Urrutia, Judy Huang, Kambiz Nael, Richard Leigh, Elisabeth B. Marsh, Argye E. Hillis, Rafael H. Llinas, Vivek S. Yedavalli
In large vessel occlusion (LVO) stroke patients, relative cerebral blood flow (rCBF)<30% volume thresholds are commonly used in treatment decisions. In the early time window, nearly infarcted but salvageable tissue volumes may lead to pretreatment overestimates of infarct volume, and thus potentially exclude patients who may otherwise benefit from intervention. Our multisite analysis aims to explore

A parcellation-based connectomic model of hemispatial neglect J. Neuroimaging (IF 2.4) Pub Date : 2023-12-19 Syed A. Ahsan, Nicholas B. Dadario, Jasneet Dhaliwal, Robert G. Briggs, Karol Osipowicz, Syed M. Ahsan, Kassem Chendeb, Andrew K. Conner, Christen M. O'Neal, Chad A. Glenn, Michael E. Sughrue
Hemispatial neglect is characterized by a reduced awareness to stimuli on the contralateral side. Current literature suggesting that damage to the right parietal lobe and attention networks may cause hemispatial neglect is conflicting and can be improved by investigating a connectomic model of the “neglect system” and the anatomical specificity of regions involved in it.

Asymmetry of thalamic hypometabolism on FDG-PET/CT in neurofibromatosis type 1: Association with peripheral tumor burden J. Neuroimaging (IF 2.4) Pub Date : 2023-11-09 Cansu Özden, Victor-Felix Mautner, Said Farschtschi, Isabel Molwitz, Inka Ristow, Peter Bannas, Lennart Well, Susanne Klutmann, Gerhard Adam, Ivayla Apostolova, Ralph Buchert
Thalamic hypometabolism is a consistent finding in brain PET with F-18 fluorodeoxyglucose (FDG) in patients with neurofibromatosis type 1 (NF1). However, the pathophysiology of this metabolic alteration is unknown. We hypothesized that it might be secondary to disturbance of peripheral input to the thalamus by NF1-characteristic peripheral nerve sheath tumors (PNSTs). To test this hypothesis, we investigated

Joundi, Brian Van Adel, Ramiro Larrazabal, Kanchana Ratnayake, Georgios Tsivgoulis, Oscar Benavente, Robert Hart, Mukul Sharma, Ashkan Shoamanesh, Luciana Catanese
Hemorrhagic transformation (HT) has been reported in up to 50% of acute ischemic stroke (AIS) patients with a large vessel occlusion (LVO) treated with endovascular thrombectomy (EVT). HT may be driven by postrecanalization hyperperfusion injury and is independently associated with worse functional outcomes.

McKnight, Lori C. Jordan, Manus J. Donahue
Choroid plexus (ChP) hyperemia has been observed in patients with intracranial vasculopathy and to reduce following successful surgical revascularization. This observation may be attributable to impaired vascular reserve of the ChP or other factors, such as the ChP responding to circulating markers of stress. We extend this work to test the hypothesis that vascular reserve of the ChP is unrelated to

In multiple sclerosis (MS), brain atrophy measurements have emerged as an important biomarker reflecting neurodegeneration and disability progression. However, due to several potential confounders, investigation of brain atrophy in clinical routine and even in controlled clinical studies can be challenging. The aim of this study was to investigate the short-term dynamics of brain atrophy development

Impact of postnatal weight gain on brain white matter maturation in very preterm infants J. Neuroimaging (IF 2.4) Pub Date : 2023-07-22 Pratheek S. Bobba, Clara F. Weber, Adrian R. Acuna Higaki, Pratik Mukherjee, Dustin Scheinost, R. Todd Constable, Laura Ment, Sarah N. Taylor, Seyedmehdi Payabvash
Very preterm infants (VPIs, <32 weeks gestational age at birth) are prone to long-term neurological deficits. While the effects of birth weight and postnatal growth on VPIs’ neurological outcome are well established, the neurobiological mechanism behind these associations remains elusive. In this study, we utilized diffusion tensor imaging (DTI) to characterize how birth weight and postnatal weight

Anatomical predictors of need for decompressive craniectomy after stroke using voxel-based lesion symptom mapping J. Neuroimaging (IF 2.4) Pub Date : 2023-07-03 Margy McCullough-Hicks, Karan Topiwala, Soren Christensen, Daniel Ruiz-Betancourt, Michael Mlynash, Gregory W. Albers
Malignant cerebral edema (MCE) secondary to ischemic stroke is a highly morbid condition. Decompressive craniectomy (DC) is the only treatment for MCE that has been shown to reduce mortality. We examined whether early infarction and/or hypoperfusion in specific topographic regions was predictive of the need for later DC.

Novel technique of stent placement via gateway balloon in intracranial atherosclerosis-associated large vessel occlusion J. Neuroimaging (IF 2.4) Pub Date : 2023-06-30 Muhammad Zeeshan Memon, Mohamad Ezzeldin, Arundhati Biswas, Rowaid Ahmad, Taha Nisar, Amit Singla, Nazar Muhammad, Hashem Shaltoni, Peter Kan, Osama O. Zaidat, Priyank Khandelwal
Neuroform Atlas stent can be deployed directly via gateway balloon for angioplasty and stent placement without the need for exchange maneuver required for Wingspan stent use. We present our initial experience of this strategy in intracranial atherosclerosis-associated large vessel occlusions.

Pretreatment brain CT perfusion thresholds for predicting final infarct volume in distal medium vessel occlusions J. Neuroimaging (IF 2.4) Pub Date : 2023-06-25 Vivek Yedavalli, Omar Hamam, Alireza Mohseni, Kwan Chen, Richard Wang, Hye-Young Heo, Jeremy Heit, Elisabeth Breese Marsh, Raf Llinas, Victor Urrutia, Risheng Xu, Fernando Gonzalez, Greg Albers, Argye Hillis, Kambiz Nael
Quantitative CT perfusion (CTP) thresholds for assessing the extent of ischemia in patients with acute ischemic stroke (AIS) have been established; relative cerebral blood flow (rCBF) <30% is typically used for estimating estimated ischemic core volume and Tmax (time to maximum) >6 seconds for critical hypoperfused volume in AIS patients with large vessel occlusion (LVO). In this study, we aimed to

Double inversion recovery MRI of subcortical band heterotopia and its variations J. Neuroimaging (IF 2.4) Pub Date : 2023-06-25 Emiko Chiba, Noriko Sato, Yukio Kimura, Yoko Shigemoto, Hiroyuki Maki, Elly Arizono, Kohei Hamamoto, Go Taniguchi, Masaki Iwasaki, Miho Ota, Hiroshi Matsuda, Eiji Nakagawa
Subcortical band heterotopia (SBH) is a malformation of cortical development diagnosed via MRI. Currently, patients with SBH are classified according to Di Donato's classification. We aimed to show a variation of SBH and the usefulness of double inversion recovery (DIR) images.

Neuroimaging of complications arising after CD19 chimeric antigen receptor T-cell therapy: A review J. Neuroimaging (IF 2.4) Pub Date : 2023-06-16 Soniya N. Pinto, Chia-Shang J. Liu, Marvin D. Nelson, Stefan Bluml, David Livingston, Benita Tamrazi
Chimeric antigen receptor (CAR) T cells targeting the CD19 (cluster of differentiation 19) cell surface glycoprotein have emerged as a highly effective immunologic therapy in patients with relapsed or refractory B-cell malignancies. The engagement of CAR T cells with CD19 on the surface of neoplastic B cells causes a systemic cytokine release, which can compromise the blood-brain barrier and cause
