Susceptibility Weighted Imaging and White Matter Abnormality Findings in Service Members With Persistent Cognitive Symptoms Following Mild Traumatic Brain Injury.

Mild traumatic brain injury (mTBI) is a major health concern among active duty service members and Veterans returning from combat operations, and it can result in variable clinical and cognitive outcomes. Identifying biomarkers that can improve diagnosis and prognostication has been at the forefront of recent research efforts. The purpose of this study was to compare the sensitivity and specificity of abnormalities identified using more traditional magnetic resonance imaging (MRI) sequences such as fluid attenuation inversion recovery (FLAIR) to more advanced MRI sequences such as susceptibility weighted imaging (SWI) among a cohort of active duty service members experiencing persistent cognitive symptoms after mTBI.

Comparing Two Processing Pipelines to Measure Subcortical and Cortical Volumes in Patients with and without Mild Traumatic Brain Injury.

Purpose: To compare volumetric results from NeuroQuant® and FreeSurfer in a service member setting. Since the advent of medical imaging, quantification of brain anatomy has been a major research and clinical effort. Rapid advancement of methods to automate quantification and to deploy this information into clinical practice has surfaced in recent years.

Postoperative imaging of the orbital contents.

Ophthalmologists perform a wide array of interventions on the orbital contents. The surgical treatment of glaucoma, cataracts, retinal detachment, and ocular trauma or malignancy results in alteration of the standard anatomy, which is often readily evident at radiologic examinations. The ability to accurately recognize the various imaging manifestations after orbital surgery is critical for radiologists to avoid misdiagnosis.

Computed tomography imaging manifestations of commonly used materials in posttraumatic craniofacial repair.

An expansive array of materials exists within the armamentarium of craniofacial surgeons. For patients undergoing repair of posttraumatic injuries, computed tomography is the imaging modality of choice in the postoperative setting. Therefore, radiologists will invariably encounter implants constructed with various materials, depending on the surgeon's preference.

Brachial plexopathy: a review of traumatic and nontraumatic causes.

Objective: This article reviews brachial plexus anatomy in the context of key landmarks, illustrates common findings of traumatic and nontraumatic causes of brachial plexopathies, describes symptoms associated with these maladies, and explains how proper diagnosis impacts clinical decisions.

Conclusion: Knowledge of brachial plexus anatomy and of the imaging sequelae of traumatic and nontraumatic plexopathies enables the radiologist to more easily identify these afflictions, thereby facilitating a multidisciplinary treatment plan and improving patient outcome.

Prospective evaluation of the role of atherosclerosis on cerebral atrophy: pilot study.

Purpose: Our purpose was to study the association between atherosclerosis measured by arterial calcium on computed tomography (CT) and cerebral atrophy demonstrated by brain magnetic resonance imaging (MRI).

Materials And Methods: IRB approved this prospective study. Twenty-one consecutive patients with acute stroke-like symptoms who are scheduled to have brain MRI were recruited on a voluntary basis.

Magnetic resonance imaging of the cervix during pregnancy: effect of gestational age and prior vaginal birth.

Objective: To investigate how gestational age and prior vaginal birth affect cervical anatomy on magnetic resonance imaging during pregnancy.

Study Design: Magnetic resonance images of the cervix were obtained in consecutive patients referred for a suspected fetal abnormality. We used an image processing protocol to measure cervical dimensions, orientation, and signal intensity.

Granulomatous Pneumocystis carinii pneumonia in a non-AIDS patient: an atypical presentation.

We present the computed tomographic findings of pulmonary involvement by granulomatous Pneumocystis carinii pneumonia in a 73-year-old woman recently tapered from a high-dose long-term systemic corticosteroid therapy for Factor VII deficiency.
