Advanced CT and MR Imaging of the Posttreatment Head and Neck
Advances in MR and computed tomography (CT) techniques have resulted in greater fidelity in the assessment of treatment response and residual tumor on one hand and the assessment of recurrent head and neck malignancies on the other hand. The advances in MR techniques primarily are related to diffusion and perfusion imaging which rely on the intrinsic architecture of the tissues and organ systems. The techniques exploit the density of the cellular architecture; and the vascularity of benign and malignant lesions which in turn affect the changes in the passage of contrast through the vascular bed. Dual-energy CT and CT perfu...

Imaging of Treated Thyroid and Parathyroid Disease
The thyroid and parathyroid glands are endocrine structures located in the visceral space of the infrahyoid neck. Imaging plays a critical role in the evaluation of patients with thyroid cancer, both in the pre and posttreatment setting. Disorders of thyroid function, that is, hyperthyroidism and hypothyroidism, are also fairly common, although imaging utilization is less frequent with these conditions. Parathyroid dysfunction results in disordered calcium metabolism. Imaging is frequently applied in the preoperative assessment of these patients undergoing parathyroidectomy; however, routine imaging in the postoperative se...

Lymph Node Dissection
The management of neck nodes in head and neck cancer is critical, given a markedly increased poor prognosis in patients with nodal metastasis. The surgical management of neck nodes has undergone radical changes secondary to a paradigm shift from curative surgery to nonsurgical organ and function-preserving options, such as radiation therapy. In the neck after treatment, radiologists should be familiar with imaging findings in various types of neck dissections and post-chemoradiation changes, along with signs of residual or recurrent disease. A multidisciplinary approach is essential with well-designed evidence-based survei...

Surgical Free Flaps and Grafts in Head and Neck Reconstruction
This review article discusses the basic principles behind the use of flaps and grafts for reconstructive surgery in the head and neck, with a special emphasis on the types of commonly used free flaps, their imaging appearance as well as some frequently encountered postoperative complications. Given the ubiquity and complexity of these reconstructive techniques, it is essential that head and neck radiologists be familiar in distinguishing between the expected evolving findings, complications, and tumor recurrence.

PET/CT and PET/MR Imaging of the Post-treatment Head and Neck
PET/computed tomography and PET/MR imaging are used to evaluate the post-treatment neck. Although 18F-FDG is helpful in the staging and treatment response assessment of head and neck cancer, recently developed PET radiotracers targeting specific surface markers are promising for applications of diagnostic problem solving and improved extent delineation. Diffusion-weighted MR imaging is helpful in the differential diagnosis of head and neck neoplasms, and improves the sensitivity and specificity for the detection of certain pathologies. Following standardized imaging parameters for PET/computed tomography and diffusion-weig...

Imaging of the Post Treatment Head and Neck
Treatment for congenital, traumatic, and neoplastic diseases of the head and neck may result in radical alterations in already complex anatomy, with structures removed either in part or in their entirety or reconstructed with hardware or grafts derived from elsewhere in the body. Expected changes in anatomy may mimic or mask recurrence of the disease treated. These procedures may result in complications that may be serious in their own right. It is no surprise then, that there is perhaps no imaging study that radiologists approach with more trepidation than cross-sectional examinations of the posttreatment head and neck. (...

Imaging of the Post Treatment Head and Neck
I am convinced from my 25+ years of practice that one of the main reasons many radiologists choose not to take vacation is because their partners, who loathe interpreting posttreatment neck studies, would “save” these studies as punishment for the vacationing radiologist! I am certainly in the minority of those who enjoy interpreting the posttreatment neck. I have always found these studies challenging and fun, albeit some of you may have a different definition of “fun.” (Source: Neuroimaging Clinics)

Neurosurgical Approaches to the Skull Base
Skull base surgery relies on the assessment of detailed neuroimaging studies to assist with surgical planning. We review typical neuroimaging features associated with common neurosurgical skull base approaches, highlighting relevant imaging anatomy and pertinent postoperative imaging appearances.

Anterior and Central Skull Base Tumors
Initially developed as a minimally invasive technique to approach inflammatory conditions, transnasal endoscopic surgery has progressively expanded its anatomic targets and clinical indications. Consequently, numerous surgical approaches to the anterior and central skull base were developed, referred to as extended endonasal approaches (EEA). The intrinsic advantage of EEA is the exploitation of a natural corridor provided by sinonasal airspaces, with no need for skin incision and osteotomy and limited soft tissue damage. In this context, imaging plays essential role, demonstrating the relevant anatomic relationships of th...
