Cardiac Computed Tomography for the Evaluation of the Acute Chest Pain Syndrome: State of the Art.

Radiol Clin North Am. 2015 Mar;53(2):297-305

Authors: Schlett CL, Hoffmann U, Geisler T, Nikolaou K, Bamberg F

Abstract
Coronary computed tomography angiography (CCTA) is recommended for the triage of acute chest pain in patients with a low-to-intermediate likelihood for acute coronary syndrome. Absence of coronary artery disease (CAD) confirmed by CCTA allows rapid emergency department discharge. This article shows that CCTA-based triage is as safe as traditional triage, reduces the hospital length of stay, and may provide cost-effective or even cost-saving care.

A Practical Approach to Interpreting Lower Extremity Noninvasive Physiologic Studies.

Radiol Clin North Am. 2014 Nov;52(6):1343-1357

Authors: McCann TE, Scoutt LM, Gunabushanam G

Abstract
Peripheral arterial disease (PAD) is an important manifestation of atherosclerosis, with an estimated age-adjusted prevalence of approximately 13% in people older than 50 years. Noninvasive vascular laboratory physiologic studies are indispensable tools in the initial evaluation and workup and postintervention follow-up. In this review, we describe a practical approach to the technique, interpretation, pitfalls, and limitations of these physiologic studies. We also provide an algorithmic approach for using these studies in the initial workup of patients with suspected PAD. Noninvasive techniques that primarily provide anatomic information have not been included in this review.

Update on the Lower Extremity Venous Ultrasonography Examination.

Radiol Clin North Am. 2014 Nov;52(6):1359-1374

Authors: Needleman L

Abstract
Lower extremity venous ultrasonography is an accurate method to diagnose acute deep venous thrombosis (DVT). Recurrent DVT is often difficult diagnosis. The decision to order ultrasonography can be based on pretest risk assessment. If the ultrasonography study is negative, the report may recommend follow-up for patients whose clinical condition changes or for patients with specific risks. Lower extremity venous ultrasonography is the gold standard for diagnosis of DVT. It is accurate and objective, and because the clinical assessment of patients is limited and its potential complication, pulmonary embolism, is significant, the impact of a positive and negative test is high.

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.

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.
