Letter from the Editor: Lung Cancer Screening Facts
Based on evidence from The 2011 National Lung Screening Trial (NLST), the United States Preventive Services Task Force (USPSTF) gave lung cancer screening a “B” recommendation and Medicare added coverage of lung cancer screening for individuals at high risk. The USPSTF recommends annual screening for lung cancer with low-dose computed tomography (LDCT) in asymptomatic adults aged 55 to 80 years who have a 30 pack-year smoking history and currently s moke or have quit within the past 15 years. Screening should be discontinued once a person has not smoked for 15 years or develops a health problem that substantially limit...

Imaging of Musculoskeletal Soft Tissue Infection
Musculoskeletal soft tissue infections account for over 2 million emergency department visits in United States annually, mostly related to cellulitis or soft tissue abscess.1 Infection of musculoskeletal soft tissues can be classified by the anatomic structures they involve: (1) skin and subcutaneous tissues (cellulitis, abscess), (2) fascia (necrotizing fasciitis), (3) muscle (infectious myositis and pyomyositis), (4) bursae (infectious bursitis), (5) and tendons and tendon sheaths (suppurative tenosynovitis).

Letter from the Editor: Surviving Three Lifetimes of Infectious Diseases
Mbah Gotho, from Java, is reportedly the longest living human.1 Born December 31, 1870, he is 145 years old. United States life expectancy statistics show that a man born in 1870 was expected to live to age 45.2.2 Mr. Gotho has already outlived three life expectancies, all 10 of his siblings, four wives, and even his children. His nearest living relatives are grand children, great grand children, and great-great grandchildren. (Source: Seminars in Roentgenology)

Nuclear Medicine Imaging of Infection
Historically, nuclear medicine was the primary modality for imaging infection. With more recent advances in cross sectional imaging technology, CT and MRI have largely replaced nuclear medicine studies for the initial diagnosis and characterization of infection. However, in specific clinical scenarios nuclear medicine continues to be an important technology for the localization and diagnosis of infection as a first-line test or as a secondary modality when other testing is nondiagnostic.

Imaging of Head and Neck Infections: Diagnostic Considerations, Potential Mimics, and Clinical management
Emergency head and neck imaging studies often elicit a unique apprehension, due to the complex anatomy and subtle imaging findings. In this review, we present commonly encountered head and neck infections, with an emphasis on clinical presentation, imaging characteristics, potential mimics of infection, and clinical management (Source: Seminars in Roentgenology)

Infections of the Brain and Meninges
Imaging findings for the various typical bacteria infecting the CNS are nonspecific and require correlation with laboratory tests to establish a definitive diagnosis. Mycobacterial and spirochetal infections have a clinical presentation and imaging appearance different from those of typical bacteria. Therefore, the following sections first discuss the various stages of pyogenic infections that occur with the majority of bacteria, followed by a description of mycobacterial (tuberculosis) and spirochetal (Lyme disease) infections (Source: Seminars in Roentgenology)

Letter from the Guest Editor: Liver Issue
The focus of the current issue of Seminars in Roentgenology “” is current and upcoming techniques in liver imaging. My vision with this issue was to provide a broad perspective on liver imaging with a mix of articles on conventional imaging techniques and newer imaging techniques through 9 articles.

Infections in the Breast —Common Imaging Presentations and Mimics
Although breast imaging focuses on cancer detection, infections of the breast may occur, especially during the postpartum period. They can occur at any age and be related to a variety of predisposing conditions such as body piercing, smoking, immunocompromised state, or underlying systemic disease. Although often localized to the breast as an acute or chronic primary process, some systemic processes can involve the breast as a secondary site. (Source: Seminars in Roentgenology)

Magnetic Resonance Imaging of the Liver (Including Biliary Contrast Agents) Part 1: Technical Considerations and Contrast Materials
Magnetic resonance imaging (MRI) plays a key role in the noninvasive evaluation of liver pathologies, because it is capable of providing comprehensive and highly accurate diagnostic information, with the additional advantage of lack of harmful ionizing radiation. (Source: Seminars in Roentgenology)

Magnetic Resonanance Imaging of the Liver (Including Biliary Contrast Agents) —Part 2: Protocols for Liver Magnetic Resonanance Imaging and Characterization of Common Focal Liver Lesions
Magnetic resonance imaging (MRI) is a fundamental tool for the noninvasive evaluation of liver pathologies. The anatomical position, the mobility with respiration, and the peculiar hemodynamics of the liver present several issues that have taken advantage from technological advances in MRI technology in the last decade, in particular regarding hardware, software, and contrast media (CM). We provided an overview of these topics in the first part of the review. (Source: Seminars in Roentgenology)
