High-yield Imaging Review of Pulmonary Infections
Publication date: Available online 13 October 2019Source: Seminars in Ultrasound, CT and MRIAuthor(s): Angelica Patino Gonzalez, Lucy Modahl, Daniel KowalAbstractImaging plays a central role in the diagnosis of pulmonary infections with the chest radiograph as the initial study of choice. CT can further delineate the extent of disease and present key imaging signs that, along with clinical history and laboratory data, can properly guide the differential diagnosis. In this article, we review and illustrate the most relevant CT imaging manifestations of common and less common pulmonary infections, including a section devoted...

Review of imaging findings in urinary tract infections
Publication date: Available online 2 October 2019Source: Seminars in Ultrasound, CT and MRIAuthor(s): A Patiño, EL Martinez-Salazar, J Tran, A Sureshkumar, T CatanzanoABSTRACTAcute urinary tract infection diagnosis is primarily performed on clinical grounds. Diagnostic imaging is, however, often necessary as part of the workup for poor response to treatment, to evaluate causative or contributory factors, complicated infections and chronic presentations. Appropriate knowledge of the most relevant radiological findings in urinary tract infections provides pertinent differential diagnosis and guides clinical management, incl...

Intracranial cns infections: a literature review and radiology case studies
This article will provide a thorough review of radiologic findings in common infections of the brain, from primarily compartmentalized infections of multi-microbial etiologies, to CNS manifestations of specific immunocompromised-selective pathogens, of herpes simplex virus (HSV), and of tuberculosis. We also briefly discuss the epidemiology, etiology, clinical features, treatment guidelines, complications, and long-term sequelae of these infections. (Source: Seminars in Ultrasound, CT and MRI)

Imaging Musculoskeletal Soft Tissue Infections
Publication date: Available online 3 October 2019Source: Seminars in Ultrasound, CT and MRIAuthor(s): Stephan Altmayer, Nupur Verma, Elizabeth A. Dicks, Amy OliveiraAbstractMusculoskeletal soft tissue infections are not uncommonly encountered in both the clinic and Emergency Department setting. The clinical diagnosis is not always evident as these infections can have variable presentations depending on the duration and depth of disease extension through the soft-tissue layers. Imaging often plays an important role in diagnosing the infection, defining the extent of involvement, directing tissue sampling, and in monitoring ...

Initial Diagnosis and Staging of Pancreatic Cancer Including Main Differentials
Publication date: Available online 30 August 2019Source: Seminars in Ultrasound, CT and MRIAuthor(s): Axel Dallongeville, Lucie Corno, Stéphane Silvera, Isabelle Boulay-Coletta, Marc ZinsAbstractComputed Tomography remains the optimal imaging modality for both diagnosis and staging of pancreatic adenocarcinoma. Especially, CT is highly accurate in assessing the relationship of the tumor to critical arterial and venous structures, since their involvement can preclude surgical resection or indicate a neoadjuvant strategy in borderline resectable or locally advanced lesions. MRI provides additional staging information in iso...

Squamous Cell Carcinoma: PET/CT and PET/MRI of the Pretreatment and Post-Treatment Neck
Publication date: Available online 17 July 2019Source: Seminars in Ultrasound, CT and MRIAuthor(s): Katie S. Traylor, Nicholas Koontz, Kristine MosierThe incidence of head and neck cancer continues to rise annually, most commonly squamous cell carcinoma (SCCa). Advances in imaging techniques have improved diagnostic accuracy with important ramifications for initial staging and post-treatment surveillance. FDG-PET/CT and, more recently, FDG-PET/MRI have revolutionized the staging and surveillance of head and neck SCCa. We detail the diagnostic role of FDG-PET/CT and FDG-PET/MRI of SCCa at the different head and neck subsite...

PET/CT Evaluation of Head and Neck Cancer of Unknown Primary
Publication date: Available online 30 July 2019Source: Seminars in Ultrasound, CT and MRIAuthor(s): Megan Albertson, Srinivasa Chandra, Zafar Sayad, Craig JohnsonAbstractThe diagnosis of carcinoma of unknown primary in the head and neck (HNCUP) is made when there is a metastasis but no primary lesion is identified after physical exam and diagnostic CT or MR imaging. PET/CT is the first step in searching for a primary lesion, followed by more invasive techniques such as endoscopy and surgery. Knowledge of the different tumor histologic types, preferential locations of nodal spread, imaging pitfalls, and other special consid...

Normal patterns and pitfalls of FDG uptake in the head and neck
Publication date: Available online 17 July 2019Source: Seminars in Ultrasound, CT and MRIAuthor(s): Benjamin R. Gray, Nicholas A. KoontzAbstractIn order to avoid misdiagnoses, medical imagers should be familiar with the normal patterns and distribution of FDG activity within the head and neck, as well as the pathophysiology and imaging-findings of common diagnostic pitfalls related to incidental FDG-avid lesions. The purpose of this article is to provide an image-rich review of the normal patterns of FDG uptake in the head and neck, help differentiate benign from malignant incidentally found FDG-avid foci, and detail impor...

PET/MRI vs PET/CT in Head and Neck imaging: When, Why, and How?
Publication date: Available online 16 July 2019Source: Seminars in Ultrasound, CT and MRIAuthor(s): Joshua Ryan, Vasantha Aaron, Justin SimsAbstractThe increasing availability of hybrid PET/MRI systems has led to a breadth of new publications and opportunities for use of PET/MRI. While PET/CT has been a valuable tool for oncologic staging, including head and neck malignancy, there are several theoretical and practical advantages a PET/MRI system would have over PET/CT in head and neck imaging. This review article discusses the established role of PET/CT, early evidence for the role of PET/MRI, and protocol considerations f...

Non-FDG Radiopharmaceuticals in Head and Neck PET Imaging: Current Techniques and Future Directions
Publication date: Available online 16 July 2019Source: Seminars in Ultrasound, CT and MRIAuthor(s): Laura B. EisenmengerAbstractPositron emission tomography (PET) has become a standard in the staging of head and neck cancer as well as can be used in locating unknown primary malignancies, monitoring disease response, and identifying disease recurrence. Although 18F-fluoro-2-deoxy-D-glucose (FDG) is by far the most frequently used radiopharmaceutical in head and neck imaging, glycolysis is not the only metabolic process or biochemical pathway that can be visualized. In addition, FDG PET can be limited due to the non-specific...

Dual-Energy CT of the Pancreas
This article explores the technical background of dual-energy CT (DECT) imaging along with its basic principles, before turning to a review of the various DECT applications specific to pancreatic imaging. In light of the most recent literature, we will review the constellation of DECT applications available for pancreatic imaging in both oncologic and non-oncologic applications. We emphasize the increased lesion conspicuity and the improved tissue characterization available with DECT post-processing tools. Finally, future clinical applications and opportunities for research will be overviewed. (Source: Seminars in Ultrasound, CT and MRI)
