  • Journal Highlights

    September 01, 2013

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

    Suspicious mass first identified at screening mammography

    Breast Ultrasonography: State of the Art

    Knowledge and understanding of current and emerging ultrasound technology—along with the application of meticulous scanning techniques—are imperative for image optimization and diagnosis. The ability to synthesize breast ultrasound findings with multiple imaging modalities and clinical information is also necessary to ensure the best patient care.

    In an article in the September issue of Radiology (RSNA.org/Radiology), Regina J. Hooley, M.D., of Yale School of Medicine, and colleagues summarize current state-of-the-art ultrasound technology—including elastography—and applications of ultrasound in clinical practice as an adjuvant technique to mammography, MR imaging and the clinical breast examinations. The authors also discuss the use of breast ultrasound for screening, preoperative staging for breast cancer and breast intervention.

    The use of screening breast ultrasound in addition to mammography, particularly in women with dense breast tissue, is becoming more widely accepted in the U.S., according to the authors.

    “In the future, as radiologists utilize ultrasound for an ever-increasing scope of indications, become aware of the more subtle sonographic findings of breast cancer and apply newly developing tools, the value of breast ultrasound will likely continue to increase and evolve,” the authors write.

    Pseudoaneurysm in a 14-year-old female after renal transplantation

The patient had undergone multiple surveillance biopsy procedures before this US evaluation. Longitudinal gray-scale US image with superimposed color Doppler image shows swirling bidirectional flow within the lumen of a pseudoaneurysm, the so-called yin-yang sign. Gray-scale images (not shown) depicted a cystic-appearing mass. At follow-up angiography, the pseudo-aneurysm had undergone spontaneous thrombosis.

    Imaging of Pediatric Renal Transplants and Their Complications: A Pictorial Review

    A technically demanding surgery with complex medical management, renal transplantation is associated with a number of complications. Anatomic imaging including ultrasonography with color and spectral Doppler and functional assessment with renal perfusion scintigraphy are complementary for the detection and characterization of posttransplant complications.

    In an article in the September-October issue of RadioGraphics (RSNA.org/RadioGraphics), Jason N. Nixon, M.D., of Seattle Children’s Hospital, and colleagues review the imaging appearances of pediatric renal transplants and their common complications. The surgical technique and postoperative and surveillance imaging are covered, followed by a description of the imaging appearance of the normal renal allograft. The authors also detail various posttransplant complications, including:

    • perinephric fluid collections
    • vascular and urologic complications
    • abnormalities of graft function
    • mass lesions

    A thorough knowledge of the imaging appearances of renal transplants and their complications facilitates prompt and accurate diagnosis, which can improve long-term graft survival and decrease the overall morbidity and mortality, according to the authors. “This goal is particularly crucial in children, given their greater number of projected life years,” the authors write.
