Patterns of Perineural Tumor Spread in Head and Neck Cancer
Perineural tumor spread (PNS) is a mode of neoplastic spread whereby tumor cells use neural conduits to escape the borders of a primary tumor. MRI is generally favored over CT…
Magnetic Resonance Imaging of the Pediatric Neck
Evaluation of neck lesions in the pediatric population can be a diagnostic challenge, for which magnetic resonance (MR) imaging is extremely valuable. This article provides an overview of the value…
Applications of Magnetic Resonance Imaging in Adult Temporal Bone Disorders
Magnetic resonance (MR) imaging has new applications in the assessment of temporal bone disorders. This article summarizes current MR imaging applications in evaluating adult temporal bone lesions according to their…
Evaluation of the Sellar and Parasellar Regions
The article reviews the anatomy and imaging evaluation of the sellar and parasellar regions. Both common and uncommon sellar and suprasellar masses are reviewed, focusing on a systematic approach to…
Myocutaneous Flaps and Other Vascularized Grafts in Head and Neck Reconstruction for Cancer Treatment
This article addresses the clinical evaluation and some of the more common flaps and grafts used to reconstruct the surgical bed after excision of primary head and neck cancers and…
MR Assessment of Oral Cavity Carcinomas
Approximately half of head and neck carcinomas arise from the oral cavity. Imaging plays an essential role in the preoperative evaluation of oral cavity carcinomas. MR imaging is particularly advantageous…
Aggressive Inflammatory and Neoplastic Processes of the Paranasal Sinuses
Although uncommon, sinonasal malignancies and aggressive inflammatory processes are entities every radiologist will encounter during the evaluation of routine sinus imaging studies. A high index of suspicion is necessary for…
MR Imaging of the Temporomandibular Joint
MR imaging allows detailed evaluation of temporomandibular (TMJ) anatomy because of its inherent tissue contrast and high resolution. Joint biomechanics can be assessed through imaging patients in the closed and…
