    The following are highlights from current issues of RSNA’s two peer-reviewed journals.

    Pericardial Disease: Value of CT and MR Imaging

    Transthoracic echocardiography, which combines structural and physiologic assessment, is the first-line technique for examination of patients suspected of having or known to have pericardial disease; however, cardiac CT and MR imaging are becoming increasingly popular for the study of this enigmatic part of the heart.

    In a review in the May issue of Radiology (RSNA.org/Radiology), Jan Bogaert, M.D., Ph.D., of University Hospitals Leuven, Belgium, and colleagues describe how CT and MR imaging have dramatically shaped the current view on imaging of pericardial disease and how these techniques may contribute to the optimization of current patient care. The authors also discuss:

    • Pericardial anatomy and physiology
    • Imaging of normal pericardium
    • Congenital and acquired pericardial disease

    The authors focus on the rapidly evolving insights regarding pericardial disease provided by modern imaging modalities, not infrequently necessitating reconsideration of evidence that has thus far been taken for granted.

    “Since pericardial diseases have substantial morbidity and perimortality, both techniques (CT, MR imaging) have an increasingly important role in decision making, particularly in determination of the optimal treatment for patients with constrictive pericarditis,” the authors write.

    Transplantation in the abdomen is an established and effective treatment option in patients with end-stage organ failure. With the increase in organ transplantations being performed, especially living donor transplantations, radiologists have a critical role in posttransplantation patient care. Although graft rejection remains a histologic diagnosis, posttransplantation imaging appearances are reliable predictors of vascular complications and their consequences.

    In an article in the May-June issue of RadioGraphics (RSNA.org/RadioGraphics), Gavin Low, M.B.Ch.B., of the University of Alberta Hospital, Canada, and colleagues offer a basic description of the standard surgical techniques performed in the abdomen and discuss the imaging appearances of vascular complications and their consequences after transplantation, including:

    • Arterial thrombosis
    • Arterial stenosis
    • Venous thrombosis and stenosis
    • Arteriovenous fistula formation
    • Pseudoaneurysm formation

    The relevant predisposing factors, clinical features, imaging appearances and potential treatment options for vascular complications of various types of transplantation are presented in a logical and integrated fashion.

    “Transplantation in the abdomen is an established and effective treatment option in patients with end-stage organ failure,” the authors write. “Radiologists have a critical role in graft monitoring and assessing complications.”

    RadioGraphics’ Call for Articles Celebrating RSNA’s 100th Anniversary

    Radiographics historic covers 

    As part of RSNA’s 100th anniversary celebration at its 2014 and 2015 annual meetings, RadioGraphics is announcing a call for articles that address an important topic in the history of radiology.

    The ideal article will incorporate material that highlights the role that RSNA or RadioGraphics has played in improving the specialty, whether in the imaging of disease or through providing quality patient care. Preference will be given to reviews that highlight the history of a particular modality, the evolution in imaging of a particular body part or region, or the progress in evaluating specific disease processes.

    Authors should contact Jeffrey S. Klein, M.D., RadioGraphics Editor, or William A. Murphy, Jr., M.D., RadioGraphics Editorial Board Member, for historical papers, with a brief outline of their proposed material prior to submission.

    All manuscripts intended for publication in 2014 must be submitted by September 3, 2013, with submissions for 2015 considered no later than September 2, 2014.

    Guidelines detailing the length and format of these manuscripts can be found at Radiographics.rsna.org/site/pia/centennialarticles.xhtml.

(c) Cyst has low signal intensity on T1-weighted spin-echo MR image (one heartbeat/30, 90° flip angle, 1.4 × 2.0-mm in-plane resolution). No cystic wall is discernible on b–c.
