Rationale and ObjectivesMedical schools were upended by the COVID-19 pandemic, resulting in suspension of all in-person educational activities, leaving clinical clerkships on hold indefinitely. A virtual curriculum novel teaching methods needed to fulfill curricular requirements. We developed a comprehensive radiology clerkship evaluated efficacy this method teaching.Materials MethodsA 4-week was designed accommodate medical students who had not yet completed required clerkship. The design...
<h3>SUMMARY:</h3> There is increasing evidence to suggest that complications of coronavirus disease 2019 (COVID-19) infection are not only limited the pulmonary system but can also involve central nervous system. Here, we report 6 critically ill patients with COVID-19 and neuroimaging findings leukoencephalopathy. While these nonspecific, postulate they may be a delayed response profound hypoxemia experienced due infection. No abnormal enhancement, hemorrhage, or perfusion abnormalities were...
<h3>SUMMARY:</h3> Myalgia is a previously reported symptom in patients with COVID-19 infection; however, the presence of paraspinal myositis has not been reported. We report MR imaging findings spine obtained cohort 9 infection who presented to our hospital between March 3, 2020 and May 6, 2020. found that 7 (78%) underwent had evidence myositis, characterized by intramuscular edema and/or enhancement. Five these prolonged course (greater than 25 days). Our knowledge manifestations...
<h3>BACKGROUND AND PURPOSE:</h3> Coronavirus disease 2019 (COVID-19) is increasingly being recognized for its multiorgan involvement, including various neurological manifestations. We examined the frequency of acute intracranial abnormalities seen on CT and/or MR imaging in patients with COVID-19 and investigated possible associations between these findings clinical parameters, length hospital stay, requirement intubation, development kidney injury. <h3>MATERIALS METHODS:</h3> This was a...
<h3>BACKGROUND AND PURPOSE:</h3> The coronavirus disease 2019 (COVID-19) pandemic has led to decreases in neuroimaging volume. Our aim was quantify the change acute or subacute ischemic strokes detected on CT MR imaging during using natural language processing of radiology reports. <h3>MATERIALS METHODS:</h3> We retrospectively analyzed 32,555 reports from brain CTs and MRIs a comprehensive stroke center, performed March 1 April 30 each year 2017 2020, involving 20,414 unique patients. To...
Background Intracranial hemorrhage is a critical finding on computed tomography (CT) of the head. This study compared accuracy an artificial intelligence (AI) model (Annalise Enterprise CTB Triage Trauma) to consensus neuroradiologist interpretations in detecting 4 subtypes: acute subdural/epidural hematoma, subarachnoid hemorrhage, intra‐axial and intraventricular hemorrhage. Methods A retrospective stand‐alone performance assessment was conducted data sets cases noncontrast CT head...
Purpose: To retrospectively review computed tomographic (CT) and clinical findings in patients with odontogenic orbital infection. Materials Methods: Approval from the institutional board was obtained for chart scan review, informed consent waived this HIPAA-compliant study. Five patients, two male three female (median age, 37 years; age range, 13–55 years), who had cellulitis underwent evaluation, CT scanning, treatment. findings, including periapical lucency suggesting abscess, sinus...
Background/Purpose Patients with neurologic complaints are imaged MRI protocols that may include many pulse sequences. It has not been documented which sequences essential. We assessed the diagnostic accuracy of a limited number in patients new complaints. Methods 996 consecutive brain studies from neurological were divided into 2 groups. In group 1, reviewers used 3-sequence set included sagittal T1-weighted, axial T2-weighted fluid-attenuated inversion recovery, and diffusion-weighted...
<h3>BACKGROUND AND PURPOSE:</h3> Fatty intrathecal lesions are a cause of tethered cord, and detection these on spinal MR imaging is paramount. Conventional T1 FSE sequences the mainstay detecting fatty elements; however, 3D gradient-echo images, volumetric interpolated breath-hold examination/liver acquisition with volume acceleration (VIBE/LAVA), popular, given increased motion resistance. We sought to evaluate diagnostic accuracy VIBE/LAVA compared for lesions. <h3>MATERIALS METHODS:</h3>...
Identification of spinal drop metastases is important in the staging and management pediatric patients with primary brain tumors. Our aim was to assess diagnostic utility balanced steady-state free precession (bSSFP) sequence (CISS/FIESTA/3D driven equilibrium radiofrequency reset pulse) for detection intracranial tumors.This a retrospective study 44 tumors undergoing MR imaging spine evaluation before radiation treatment. All underwent whole-spine MRI both bSSFP postcontrast T1WI sequences....
Mass effect and vasogenic edema are critical findings on CT of the head. This study compared accuracy an artificial intelligence model (Annalise Enterprise CTB) with consensus neuroradiologists' interpretations in detecting mass edema.
Severe respiratory distress in patients with COVID-19 has been associated higher rate of neurologic manifestations. Our aim was to investigate whether the severity chest imaging findings among coronavirus disease 2019 (COVID-19) correlates risk acute neuroimaging findings.This retrospective study included all who received care at our hospital between March 3, 2020, and May 6, underwent within 10 days neuroimaging. Chest radiographs were assessed using a previously validated automated neural...
Machine learning (ML) algorithms to detect critical findings on head CTs may expedite patient management. Most ML for diagnostic imaging analysis utilize dichotomous classifications determine whether a specific abnormality is present. However, be indeterminate, and algorithmic inferences have substantial uncertainty. We incorporated awareness of uncertainty into an algorithm that detects intracranial hemorrhage or other urgent abnormalities evaluated prospectively identified, 1000...
Abstract Background Data on clinical outcomes for base of skull (BOS) chordomas in the pediatric population is limited. We report patient after surgery and proton radiotherapy (PRT). Methods Pediatric patients with BOS were treated PRT or combined proton/photon approach (proton-based; most, 80% proton/20% photon) at Massachusetts General Hospital from 1981 to 2021. Endpoints interest overall survival (OS), disease-specific survival, progression-free (PFS), freedom local recurrence (LC),...
Contrast-enhanced MRI (CEMRI) is a commonly used imaging modality for craniopharyngioma surveillance; however, it carries risks such as allergic reaction and gadolinium deposition. This study evaluates the efficacy of non-contrast enhanced (NCMRI) with balanced steady state free precession (bSSFP) sequence compared CEMRI T1-weighted surveillance.
A 24-year-old woman with a 3 year history of multiple sclerosis, for which she was treated beta interferon, found to have T2 intermediate mass (1.3 cm ¥ 0.7 cm) within the left internal auditory canal (Figure 1) in follow up MRI.There no associated effect on adjacent brain parenchyma.In addition, there were numerous hyperintense lesions throughout supratentorial white matter, consistent known sclerosis.At time, did not any related symptoms; reported abnormality hearing or balance, and facial...
<h3>BACKGROUND AND PURPOSE:</h3> MR imaging has been shown to be useful in the diagnosis of juvenile idiopathic arthritis temporomandibular joint. Prior approaches have relied mainly on subjective interpretation synovial enhancement as a marker for inflammation. Although, more recently, several attempts made quantify enhancement, these methods not taken into account dynamic characteristics joint and effect sampling time. Our aim was develop clinically feasible, reproducible, dynamic,...
