Course Description

Whether you’re a resident or a general radiologist who needs a refresher, understanding orbital anatomy, imaging best practices, and common pathologies is essential.

Join Dr. David Yousem, from Johns Hopkins University School of Medicine, as he shares pearls and pitfalls of orbital imaging, garnered over years of experience and interest in this topic.

Through case-based video discussion and 40+ full DICOM studies that you can view and manipulate, this course will prepare even the busiest radiologist to confidently and efficiently identify abnormalities of the ocular, intraconal, conal, and extraconal spaces, and explore common pathologies that affect the orbits.

Topics covered in this course:

Orbital imaging protocols for CT and on MRI
Imaging artifacts in MRI and CT
Ocular anatomy
Anatomy of the conal space and extraconal orbit and relevant pathology
Case review of diagnoses like: endophthalmitis, juvenile ossifying fibroma, lacrimal gland lymphoma microphthalmia, neuromyelitis optica spectrum disorder, optic neuritis, orbital fractures, orbital pseudotumor, periorbital cellulitis, PHPV, pilocytic astrocytoma, retinal detachment, retinoblastoma, staphyloma, thyroid eye disease, venous vascular malformation, and more
Imaging appearances of orbital abnormalities, differential considerations, and treatment options
…and more!

What your colleagues liked about this Radiology CME course:

“The repetitions and the anatomical based explanations have been amazing.” – A.K., MD
“What a beast. Excellent presentation and case examples.” – S.G., MD
“[This course] was a very good summary of orbital diseases…Now I will more carefully look at this region especially in trauma cases.” – U.L., MD

After you’re done, check out these additional Neuroradiology Mastery Courses for further in-depth case review:

In the Imaging Mastery Series: Orbit, Dave Yousem, MD walks you through everything you need to know about imaging the orbits, covering protocol, anatomy, and a case review session centered around ocular pathology.
