Differentiating pseudoprogression from true tumor progression has become a significant challenge in follow-up of diffuse infiltrating gliomas, particularly high grade, which leads to potential treatment delay for patients with early glioma recurrence. In this study, we proposed use multiparametric MRI data as sequence input the convolutional neural network recurrent based deep learning structure discriminate between and progression. 43 biopsy-proven patient identified whose disease...
Objective To characterise the clinical course of delirium for patients with COVID-19 in intensive care unit, including postdischarge neuropsychological outcomes. Design Retrospective chart review and prospective survey study. Setting Intensive units, large academic tertiary-care centre (USA). Participants Patients (n=148) admitted to an unit at Michigan Medicine between 1 March 2020 31 May were eligible inclusion. Primary secondary outcome measures Delirium was primary outcome, assessed via...
Free flap reconstruction in patients with head and neck cancer carries a risk of postoperative complications, radiologic predictive factors have been limited. The aim this study was to assess the that predict free failure using CT MR perfusion.This single-center prospective included 24 (mean age, 62.7 [SD, 9.0] years; 16 men) who had from January 2016 May 2018. perfusion dynamic contrast-enhanced imaging conventional were performed between 2 4 days after surgery, wound assessments within 14...
Evidence-based treatments for chronic low back pain (cLBP) typically work well in only a fraction of patients, and at present there is little guidance regarding what treatment should be used which patients. Our central hypothesis that an interventional response phenotyping study can identify individuals with different underlying mechanisms their who thus respond differentially to evidence-based cLBP. Thus, we will conduct randomized controlled Sequential, Multiple Assessment, Randomized...
Background: Stroke is a devastating perioperative complication without effective methods for prevention or diagnosis. The objective of this study was to analyze evidence-based strategies detecting cerebrovascular vulnerability and injury in high-risk cohort non-cardiac surgery patients. Methods: This single-center, prospective study. Fifty patients undergoing were recruited -25 with known disease 25 matched controls. Neurologic measured intraoperative cerebral oximetry as the primary...
Abstract Objective The objective of this study was to understand current practice, clinician understanding, attitudes, barriers, and facilitators optimal headache neuroimaging practices. Background Headaches are common in adults, for these patients is common, costly, increasing. Although guidelines recommend against routine low‐risk scenarios, guideline‐discordant still frequently performed. Methods We administered a 60‐item survey clinicians at the Veterans Affairs health system assess...
Abstract Management of patients suffering from low back pain (LBP) is challenging and requires development diagnostic techniques to identify specific patient subgroups phenotypes in order customize treatment predict clinical outcome. The Back Pain Consortium (BACPAC) Research Program Spine Imaging Working Group has developed standard operating procedures (SOPs) for spinal imaging protocols be used all BACPAC studies. These SOPs include conduct assessments with guidelines standardizing the...
Abstract Background and Purpose Differentiating schwannomas metastases in the cerebellopontine angles (CPA)/internal auditory canals (IAC) can be challenging. This study aimed to assess role of diffusion‐weighted imaging (DWI) dynamic contrast‐enhanced MRI (DCE‐MRI) differentiate CPA/IAC. Methods We retrospectively reviewed 368 patients who were diagnosed with or CPA/IAC between April 2017 February 2022 a single academic center. Forty‐three had pretreatment DWI DCE‐MRI along conventional...
Amyloidomas are focal solitary amyloid masses without systemic involvement that have been observed to occur in various body locations. When presenting intracranially, they pose a challenging diagnostic and therapeutic course given their location rarity. We report case of 62-year-old man with 4-year history seizure headaches. Magnetic resonance imaging was initially inconclusive but revealed an ill-defined right temporal lobe lesion. Biopsy later confirmed cerebral amyloidoma. also review the...
This study aims to compare the image quality of clinical brain imaging on an FDA-approved commercial low-field 0.55T MRI scanner and conventional higher field 1.5/3T systems. The 205 compatible series in 30 patients acquired at 1.5T/3T systems was rated by two neuroradiologists. Despite significant differences ratings between low- higher-field scanners, all sequences performed received indicating that they were acceptable for diagnostic use. work indicates system can be used routine practice.
Introduction: Arterial wall enhancement detected on vessel MRI (vwMRI) has been associated with increased stroke risk in the setting of intracranial atherosclerosis. Other pathologies affect wall, including cerebral amyloid angiopathy (CAA). CAA is secondary to Aβ deposition resulting microvessel leakage, microbleeds and ischemic stroke. Our goal was determine if vwMRI could detect inflammation leptomeningeal contrast leakage CAA, these are recent infarction. Methods: In this retrospective...
Abstract Objective To characterize the clinical course of delirium for COVID-19 patients in intensive care unit, including post-discharge cognitive outcomes. Patients and Methods A retrospective chart review was conducted diagnosed with (n=148) admitted to an unit at Michigan Medicine between March 1, 2020 May 31, 2020. validated method used identify presence delirium, various measures (e.g., Family Confusion Assessment Method, Short Blessed Test, Patient-Health Questionnaire-9) were...
MRI features of tumor progression and pseudoprogression may be indistinguishable especially without enhancing portion the diffuse gliomas. Our aim is to discriminate these two conditions using radiomics machine learning algorithm compare them with human observations. Three consecutive studies before a definitive biopsy in 43 glioma patients (7 36 true cases) who underwent treatment were evaluated. Two neuroradiologists reviewed pre- post-contrast T1, T2, FLAIR, ADC, rCBV, rCBF, K2, MTT maps....
