Neuroimaging in the First 6 Weeks of the COVID-19 Pandemic in an 8-Hospital Campus: Observations and Patterns in the Brain, Head and Neck, and Spine.

Objective: The aim of the study was to aggregate neuroradiological findings in patients with coronavirus disease 2019 (COVID-19) in the brain, head and neck, and spine to identify trends and unique patterns.

Methods: A retrospective review of neuroimaged COVID-19 patients during a 6-week surge in our 8-hospital campus was performed. The brain imaging with reported acute or subacute infarction, intraparenchymal hemorrhage, and all neck examinations were reinterpreted by 2 reviewers.

Impact of formal training on agreement of videofluoroscopic swallowing study interpretation across and within disciplines.

Purpose: Formal agreement studies on interpretation of the videofluoroscopic swallowing study (VFSS) procedure among speech-language pathologists, radiology house officers, and staff radiologists have not been pursued. Each of these professions participates in the procedure, interprets the examination, and writes separate reports on the findings. The aim of this study was to determine reliability of interpretation between and within the disciplines and to determine if structured training improved reliability.

Osteolytic mass bridging two cervical vertebrae: Unusual presentation of a vertebral body hemangioma.

Vertebral hemangioma is the most common spinal axis tumor. This rare presentation of a vertebral hemangioma extended contiguously from one cervical vertebra to another, encasing the vertebral artery, and thereby mimicking other tumors of the spine. We discuss the differential diagnosis of bridging vertebral masses.

The role of saline flush injection rate in displacement of CT-injectable peripherally inserted central catheter tip during power injection of contrast material.

Objective: The purpose of this article is to determine the rate and the cause of displacement of CT power-injectable peripherally inserted central catheters (CT-PICCs) during contrast material and saline flush injection and to modify CT-scanning protocols to decrease the frequency of displacement.

Materials And Methods: In the laboratory setting, in vitro modeling of CTPICC displacement during power injection was examined while varying the initial rate of injection of the saline flush. In the clinical setting, the CT images of all patients at a large academic hospital for one calendar year who underwent power injection of CT contrast media were reviewed for CT-PICC displacement.

Spine infections.

Infections of the spine represent a rare but potentially debilitating and neurologically devastating condition for patients. Early diagnosis, imaging, and intervention may prevent some of the more critical complications that may ensue from this disease process, including alignment abnormalities, central canal compromise, nerve root impingement, vascular complications, and spinal cord injury. This article reviews the underlying pathophysiologic basis of infection, clinical manifestations, and imaging modalities used to diagnose infections of the spine and spinal cord.

T1 hyperintense disc in alkaptonuria.

Study Design: Case report.

Objective: To report a rare case of alkaptonuria presenting as a T1-hyperintense disc herniation.

Summary Of Background Data: A 46-year-old man without previous diagnosis of alkaptonuria underwent evaluation for progressive back pain revealing a T1-hyperintense disc herniation at the L3-L4 level.

Imaging findings of bisphosphonate-related osteonecrosis of the jaw with emphasis on early magnetic resonance imaging findings.

Purpose: To describe the imaging findings of bisphosphonate-related osteonecrosis of the jaw (BRONJ) with emphasis on early magnetic resonance imaging (MRI) findings.

Materials And Methods: The medical records and computed tomography, MRI, and bone scintigraphy images of 5 female and 1male patients (n = 6) between the ages of 49 and 79 years (mean age, 70 years) who had a diagnosis of BRONJ were retrospectively reviewed, and temporal changes in imaging features were noted.

Results: The earliest MRI finding was the loss of the normal T1 hyperintensity of fatty marrow in the mandible and maxilla.

Cost-effectiveness of helicopter transport of stroke patients for thrombolysis.

Objectives: Treatment with intravenous (IV) or intra-arterial (IA) thrombolysis in patients with acute ischemic stroke demands careful patient selection and specialized institutional capabilities. Physicians at hospitals without these resources may prefer patient transfer for acute treatment. Helicopter transport for these patients has been described but without analysis of the effects of its additional cost.

Alveolar soft-part sarcoma of the neck.

We report a case of alveolar soft-part sarcoma involving the posterior paraspinal musculature of the neck. This rare tumor of uncertain histogenesis typically occurs in the lower extremities in young adults and in the tongue or orbit in infants.
