MR Imaging of the Biliary System.

Radiol Clin North Am. 2014 Jul;52(4):725-755

Authors: Yam BL, Siegelman ES

Abstract
Although ultrasound, computed tomography, and cholescintigraphy play essential roles in the evaluation of suspected biliary abnormalities, magnetic resonance (MR) imaging and MR cholangiopancreatography can be used to evaluate inconclusive findings and provide a comprehensive noninvasive assessment of the biliary tract and gallbladder. This article reviews standard MR and MR cholangiopancreatography techniques, clinical applications, and pitfalls. Normal biliary anatomy and variants are discussed, particularly as they pertain to preoperative planning. A spectrum of benign and malignant biliary processes is reviewed, emphasizing MR findings that aid in characterization.

MR Enterography for Assessment and Management of Small Bowel Crohn Disease.

Radiol Clin North Am. 2014 Jul;52(4):799-810

Authors: Allen BC, Leyendecker JR

Abstract
Magnetic resonance enterography (MRE) utilization has increased for the evaluation of small bowel diseases over the last several years. In addition to performing similarly to computed tomography enterography (CTE) in the evaluation of inflammatory bowel disease, MRE lacks ionizing radiation, can image the small bowel dynamically, and provides excellent soft tissue contrast resolution. This article reviews imaging protocols for MRE, normal MR imaging appearance of small bowel, and the imaging findings of small bowel Crohn disease. The importance of imaging findings for directing management in patients with small bowel Crohn disease is emphasized throughout.

MR Imaging of the Pancreas.

Radiol Clin North Am. 2014 Jul;52(4):757-777

Authors: O'Neill E, Hammond N, Miller FH

Abstract
Magnetic resonance (MR) imaging of the pancreas is useful as both a problem-solving tool and an initial imaging examination of choice. With newer imaging sequences such as diffusion-weighted imaging, MR offers improved ability to detect and characterize lesions and identify and stage tumors and inflammation. MR cholangiopancreatography can be used to visualize the pancreatic and biliary ductal system. In this article, the use of MR to evaluate the pancreas, including recent advances, is reviewed and the normal appearance of the pancreas on different imaging sequences, as well as inflammatory diseases, congenital abnormalities, and neoplasms of the pancreas, are discussed.

The idiopathic interstitial pneumonias: an update and review.

Radiol Clin North Am. 2014 Jan;52(1):105-20

Authors: Hobbs S, Lynch D

Abstract
Idiopathic interstitial pneumonias (IIPs) are a group of disorders with distinct histologic and radiologic appearances and no identifiable cause. The IIPs comprise 8 currently recognized entities. Each of these entities demonstrates a prototypical imaging and histologic pattern, although in practice the imaging patterns may overlap, and some interstitial pneumonias are not classifiable. To be considered an IIP, the disease must be idiopathic; however, each pattern may be secondary to a recognizable cause, most notably collagen vascular disease, hypersensitivity pneumonitis, or drug reactions. The diagnosis of IIP requires the correlation of clinical, imaging, and pathologic features.

Thoracic infections in immunocompromised patients.

Radiol Clin North Am. 2014 Jan;52(1):121-36

Authors: Ahuja J, Kanne JP

Abstract
Infections account for approximately 75% of all pulmonary complications in immunocompromised patients, and early and accurate diagnosis is essential because of associated high morbidity and mortality. The number of immunocompromised patients continues to increase because of greater use of immunosuppressive agents. Certain organisms are likely to cause infection with certain types of immunosuppression and during specific times during the course of immunosuppression. Knowledge of the acuity of the patient's illness, environmental exposures, nature of the underlying immune defect(s), and duration and severity of immunodeficiency can help the radiologist provide a more accurate differential diagnosis for the cause of pulmonary infection.
