Optical Coherence Tomography for the Radiologist
Optical coherence tomography is an imaging technique using low coherence light sources to produce high-resolution cross-sectional images. This article reviews pertinent anatomy and various pathologies causing optic atrophy (eg, compressive,…
Diagnostic Ophthalmic Ultrasound for Radiologists
Ophthalmic ultrasound is an invaluable tool that provides quick and noninvasive evaluation of the eye and the orbit. It not only allows the clinicians to view structures that may not…
Imaging of Pediatric Orbital Diseases
This article reviews a variety of congenital and developmental disorders of the pediatric orbit with particular emphasis on ocular lesions, followed by a description of developmental and neoplastic orbital and…
Imaging in Sinonasal Inflammatory Disease
While most patients with inflammatory rhinosinusitis are successfully diagnosed clinically, imaging is indicated in patients with recurrent or chronic sinusitis, atypical symptoms and complicated acute sinusitis. Non-enhanced high resolution, thin…
Imaging of the Postoperative Orbit
Imaging evaluation of the postoperative orbit remains challenging even for the expert neuroradiologist. This article provides a simplified framework for understanding the complex postoperative appearances of the orbit, in an…
Imaging of Orbital Trauma and Emergent Non-traumatic Conditions
Diagnostic imaging has become critical in the care of patients suffering from traumatic or nontraumatic emergent orbital conditions. Multidetector computed tomography (MDCT) has become the standard imaging modality for assessing…
Imaging of Ocular Motor Pathway
Eye movement is controlled by ocular motor pathways that encompass supranuclear, nuclear, and infranuclear levels. Lesions affecting certain locations may produce localizing signs that help radiologists focus on specific anatomic…
Imaging of Retrochiasmal and Higher Cortical Visual Disorders
Retrochiasmal visual pathways include optic tracts, lateral geniculate nuclei, optic radiations, and striate cortex (V1). Homonymous hemianopsia and field defect variants with relatively normal visual acuity suggest that the lesions…
Imaging of Optic Neuropathy and Chiasmal Syndromes
Optic neuropathy involves loss of visual acuity, color vision, and visual field defect with a swollen, pale, anomalous, or normal optic disc seen on fundoscopy. Chiasmal disorders classically present with…
