Interventional Radiology for Liver Lesions
The liver plays a major role in bodily functions, including digestion, sugar and fat metabolism, and the body ’s immune defense. Furthermore, the liver is also the largest internal organ in the body, accounting for 4% of the body weight. However, the liver is also a common site of disease, which includes primary malignancy such as hepatocellular carcinoma (HCC) and secondary malignancy such as liver metas tases, with the most common primary source being colorectal cancer. Data from the World Health Organization show that there were 700,000 people around the world who died from liver cancer in 2008. (Source: Seminars in Roentgenology)

Contrast-Enhanced Ultrasound of Focal Liver Lesions
Focal liver lesions (FLL) are one of the most frequently diagnosed liver pathologies.1 Their detection and characterization forms a major part of referral work in day-to-day radiology practice. FLL may present with symptoms but are very often picked up on routine ultrasound (US) in asymptomatic patients. In patients with known neoplasms anywhere in the body or in those with liver cirrhosis, they are often detected as a part of surveillance. It is imperative to characterize these lesions to decide further management. (Source: Seminars in Roentgenology)

Clinical Applications of Dual-Energy Computed Tomography in the Liver
Dual-energy computed tomography (DECT) scanners have been increasingly available in many institutions, however, implementation into routine clinical practice in liver imaging has not been widespread because of multifactorial reasons including issues related to standardization of protocols and post processing. DECT not only provides images similar to those obtained with single-energy computed tomography (CT), but also has the capability of iodine extraction and material decomposition. Technical approaches offered by vendors and basic principles have been described in detail in several published literature. (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)

Imaging of Spine Infection
Spine infection may involve the vertebral bodies with or without involvement of the intervertebral disc (spondylitis or spondylodiscitis), the posterior neural elements, the paraspinal soft tissues, and the spinal canal including the epidural space, the meninges, the spinal cord, and the nerve roots.1-3 Bacteria are the most common causes of extradural and intradural extramedullary infection, whereas viruses are most frequently responsible for intramedullary infections.2 The incidence of spinal infection is 0.2-2 cases per 100,000 per year, with a peak in the sixth decade.

Magnetic Resonance Imaging of Hepatic Abscesses
The infiltration of normal or diseased hepatic parenchyma by bacteria or microorganisms can result in a cavitated lesion, which is defined as a hepatic abscess. These microorganisms can enter into the hepatic parenchyma via the biliary system, hematogenously, or through direct contiguous spread from adjacent structures. In the Western world, pyogenic hepatic abscesses are the most prevalent form; in Southeast Asia and Africa, amebic hepatic abscesses are most common.1 Underlying biliary disease, comorbidities (eg, diabetes and immunocompromised states), and severity of hepatic involvement are prognostic indicators.
