- Assistant Professor, Medical Imaging
Following completion of a diagnostic radiology residency at the University of Texas Health Science Center at San Antonio, I performed a 2-year Neuroradiology fellowship at the University of Utah. As a second year Neuroradiology fellow and clinical instructor, I honed my skills as a clinical Neuroradiologist interpreting brain, spine, head and neck, and pediatric neuroradiology imaging, as well as, image guided procedures. I also participated in staffing residents, presenting lectures and resident case conferences, tumor board preparation, presented at national meeting and a CME course, wrote peer reviewed journal articles, and edited multiple book chapters.
After Neuroradiology fellowship, I accepted a position as Assistant Professor in Medical Imaging at the University of Arizona in the division of Neuroradiology. In addition to performing my clinical duties, I enjoy staffing residents and fellows and have been appointed the Director of Neuroradiology Resident Education, which entailed the development of a 2 year cirriculum, updating a neuroradiology teaching file, and establishing new teaching resources for neuroradiology education.
My research interests are in the realm of head and neck imaging, particularly facial trauma, orbital pathology, head and neck cancer, and temporal bone imaging.

Radiographics : a review publication of the Radiological Society of North America, Inc, 33(1), 3-19.More infoMultidetector computed tomography (CT) is the modality of choice for the evaluation of facial trauma because it helps accurately identify and characterize fractures and associated complications, thereby aiding timely clinical management and surgical planning. In particular, CT clearly depicts clinically relevant fractures in the eight osseous struts or buttresses that function as an underlying scaffold for facial structures. Information about the involvement of specific facial buttresses in a complex fracture is helpful for determining the type of fracture present and for identifying associated soft-tissue injuries that may require urgent care or surgery. Various kinds of complications can be expected to occur in Le Fort fractures, which affect the full thickness of the pterygoid plates, with resultant dissociation of part or all of the maxilla from the skull base; naso-orbitoethmoid complex fractures, which involve the medial orbital wall, nasal bone, ethmoid sinuses, and, often, the attachment site of the medial canthal tendon; zygomaticomaxillary complex fractures, which disrupt all four zygomatic sutures and may lead to enophthalmos due to increased orbital volume because of angulation of the lateral orbital wall; orbital "blowout" fractures, which may result in extraocular muscle herniation or entrapment and injuries to the globe or the infraorbital nerve; and fractures of the alveolar process, which are treated as open fractures because of their extension through the gingiva to the oral cavity and their resultant vulnerability to infection. Similarly, extension of a frontal sinus fracture through the posterior sinus wall creates a portal to the anterior cranial fossa and may lead to cerebrospinal fluid leakage, intracranial hemorrhage, or intracranial infection.

Journal of nuclear medicine technology.More infoA 56-year old male received a total thyroidectomy, bilateral central and right lateral neck dissection for papillary thyroid carcinoma with lymph nodes metastases. Prior to radioiodine ablation the pre-therapy I scan established the diagnosis of primary nasolacrimal duct obstruction (dacryostenosis).
- Kay, M. D., Pariury, H. E., Perry, A., Winegar, B. A., & Kuo, P. H. (2019). Extracranial Metastases From Glioblastoma With Primitive Neuronal Components on FDG PET/CT. Clinical nuclear medicine.More infoA 17-year-old girl with World Health Organization grade IV glioblastoma with primitive neuronal components (histone H3 G34-mutant and IDH1 wild type) underwent whole-body FDG PET/CT staging due to vertebral metastases on initial MRI. PET/CT revealed extracranial metastatic disease with spinal leptomeningeal dissemination, osseous metastases, and peritoneal seeding via a ventriculoperitoneal shunt. Glioblastoma is uncommon in pediatric patients and particularly those with primitive neuronal components. Extracranial metastases from glioblastoma are more common in those with primitive neuronal components. This case demonstrates the utility of FDG PET/CT for revealing distant metastases from glioblastoma.

Seminars in musculoskeletal radiology, 23(2), e56-e79.More infoThis article discusses instrumented spinal surgeries, the radiologic assessment of spinal fixation hardware, and the potential complications of spinal hardware. Radiography is the standard for the postoperative assessment of spinal hardware. Computed tomography and magnetic resonance imaging play a valuable role in the detection of hardware and postsurgical-related complications such as infection, pseudarthrosis, and malpositioned instrumentation. Familiarity with the normal imaging appearance of implanted spinal hardware along with the expected progression of normal postoperative osseous arthrodesis enables recognition of potential complications and helps facilitate appropriate clinical management.

Journal of AAPOS : the official publication of the American Association for Pediatric Ophthalmology and Strabismus, 19(6), 574-7.More infoWe report the case of a 15-month-old boy with retinoblastoma who developed exotropia secondary to a right medial rectus infarct after intra-arterial chemotherapy. He had unilateral sporadic group C tumor (International Classification of Retinoblastoma) and was treated with intra-arterial melphalan. One week after the first session of intra-ophthalmic arterial melphalan chemotherapy, he was noted to have orbital congestion, exotropia, and right adduction limitation. Magnetic resonance imaging was suggestive of a right medial rectus infarct. The tumor showed a good response to intra-arterial chemotherapy but the exotropia persisted.
- Winegar, B. A., & Gutierrez, J. E. (2015). Imaging of Orbital Trauma and Emergent Non-traumatic Conditions. Neuroimaging clinics of North America, 25(3), 439-56.More infoDiagnostic 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 orbital trauma because of its accurate assessment of orbital skeletal and soft tissues injuries. Contrast-enhanced MR imaging is the first-line examination in the assessment of nontraumatic orbital conditions given its excellent evaluation of the orbital soft tissues. Conventional angiography is necessary in some vascular orbital complications and allows for endovascular treatment. This article discusses the spectrum of orbital pathology encountered in the imaging of orbital trauma and nontraumatic orbital emergencies.
