Imaging Approach to Sinonasal Neoplasms
The neoplastic lesions that can be found in the sinonasal space are numerous and varied. This article describes a general approach to narrowing down the differential diagnosis and provides the…
Fungal Sinusitis
Key points • Fungal sinusitis is classified into invasive and noninvasive forms based on histopathologic evidence of tissue invasion by fungi. • The invasive category includes acute invasive, chronic invasive,…
Normal Anatomy and Anatomic Variants of the Paranasal Sinuses on Computed Tomography
It is imperative for all imaging specialists to be familiar with detailed multiplanar CT anatomy of the paranasal sinuses and adjacent structures. This article reviews the radiologically relevant embryology of…
Paranasal Sinuses—Decongested!
Varsha M. Joshi, DNB, DMRD, Editor The last three decades have witnessed tremendous progress in the imaging evaluation of the paranasal sinuses. Driven by the introduction and numerous advances in…
Imaging of Paranasal Sinuses
Suresh K. Mukherji, MD, MBA, FACR, Consulting Editor I have the distinct pleasure to welcome and thank Dr Varsha Joshi for editing this issue of Neuroimaging Clinics on the paranasal sinuses….
Unusual Cerebral Emboli
Key points • A multiplicity of acute small infarcts in different vascular territories is a common manifestation of cerebral embolism. • Diffuse white matter blooming foci on T2* MR imaging…
Three-Dimensional Ultrasound of Carotid Plaque
Measurement of plaque burden is different from measurement of carotid intima-media thickness (IMT). Carotid total plaque area is a stronger predictor of cardiovascular risk than IMT, and in contrast to…
Analysis of Multicontrast Carotid Plaque MR Imaging
Plaque imaging by MR imaging provides a wealth of information on the characteristics of individual plaque that may reveal vulnerability to rupture, likelihood of progression, or optimal treatment strategy. T1-weighted…
Low-Grade Carotid Stenosis
Key points • Luminal imaging techniques do not adequately evaluate extracranial carotid atherosclerotic plaque burden and characteristics in patients with low-grade carotid stenosis. • Although multiple randomized controlled trials have…
