    Dominant intraprostatic cancer confirmed by direct MRI-guided biopsy: Concordance with histopathological findings.
    Clin Imaging 2018 Jun 9;51:273-278. Epub 2018 Jun 9.
    Department of Diagnostic Radiology, Oregon Health & Science University, United States. Electronic address:
    Purpose: To investigate the concordance between dominant intraprostatic cancer seen on endorectal multiparametric MRI and confirmed by MRI-targeted biopsy with histopathological findings at radical prostatectomy, since existing literature has emphasized the miss rather than the concordance rate of MRI.

The large sphenoethmoidal defect was associated with transethmoidal and orbital cephalocele as well as inferolateral herniation of the frontal lobe. Read More

    High resolution vessel wall MRI and vasculopathy related to herpes zoster ophthalmicus.
    Clin Imaging 2018 May 3;50:336-339. Epub 2018 May 3.
    Department of Radiology, Massachusetts General Hospital, Boston, MA, USA.
    Varicella zoster virus is a common viral infection with over 50% of patients over the age of 80 years infected with the virus. Following reactivation, some patients succumb to complications of VZV reactivation with neurologic and optic pathway pathology such as VZV vasculopathy resulting in transient ischemic attacks, strokes, aneurysms, as well as optic neuritis. We show that high resolution vessel wall magnetic resonance imaging can aid in the diagnosis of this condition with circumferential wall thickening and enhancement of the infected vessels. Read More

    Lobular capillary hemangioma of the mandible: A case report.
    Clin Imaging 2018 Apr 13;50:246-249. Epub 2018 Apr 13.
    Stanford University School of Medicine, 300 Pasteur Drive, Room S-047, Stanford, CA 94305, United States.
    Lobular capillary hemangiomas are acquired benign vascular neoplasms which typically affect the skin and mucous membranes. While these lesions commonly involve the head and neck, particularly the oral cavity, there are no reports in the literature of lobular capillary hemangioma arising from the mandible. The diagnosis of such a rare entity can therefore be challenging, especially as it may mimic more aggressive lesions, including malignancy. Read More

    The need to be all inclusive: Chest CT scans should include imaged breast parenchyma.
    Clin Imaging 2018 Apr 19;50:243-245. Epub 2018 Apr 19.
    Department of Radiology, Icahn School of Medicine at Mount Sinai, New York, NY, United States.
    The benefits of early diagnosis and treatment of breast cancer are well established. Thoracic CT which is performed with increased frequency for lung cancer screening can diagnose breast cancer earlier then might be possible clinically. The imaged and radiation exposed breasts must be included in their entirety on images which are reviewed by the radiologist. Read More

    Aorto-left atrial fistula diagnosed with computed tomographic angiography: A case report.
    Clin Imaging 2018 Apr 14;50:235-238. Epub 2018 Apr 14.
    Department of Radiology, Icahn School of Medicine at Mount Sinai Hospital. Electronic address:
    Aorto-atrial fistulas are a rare diagnosis with limited reports in the clinical literature. These findings are often characterized by echocardiography alone; however, the advent and increased availability and use of CT angiography to diagnose cardiac abnormalities provides improved anatomic visibility of potential defects. We are reporting a case of a 76-year-old male with decompensated heart failure secondary to a fistula between the aorta and left atrium after remote history of bioprosthetic aortic valve replacement.

    Ultrasound elastography in assessment of salivary glands involvement in primary Sjögren's syndrome.
    Clin Imaging 2018 Apr 14;50:229-234. Epub 2018 Apr 14.
    Gazi University Faculty of Medicine, Department of Rheumatology, Ankara, Turkey.
    Objective: Our study aimed to assess the pathological sonoelastographic changes in the major salivary glands and to demonstrate the diagnostic effectiveness of Sonoelastography as an additional method to US in Sjögren's syndrome.

    Methods: Fifty eight patients with primary Sjögren's syndrome (pSS) were selected according to the American-European Consensus Group Classification criteria. Twenty five healthy volunteers involved in this study. Read More

    Diagnostic accuracy of MDCT in differentiating gallbladder cancer from acute and xanthogranulomatous cholecystitis.
    Clin Imaging 2018 Apr 14;50:223-228. Epub 2018 Apr 14.
    Department of Radiology, University of Michigan Health System, 1500 E. Medical Center Dr., Ann Arbor, MI 48109, United States.
    Objective: To determine the diagnostic accuracy of multi-detector CT (MDCT) for differentiating gallbladder cancer from acute and xanthogranulomatous cholecystitis using previously described imaging features.

    Methods: In this IRB approved HIPAA-compliant retrospective cohort study, contrast-enhanced MDCT of histologically confirmed acute cholecystitis (n = 17), xanthogranulomatous cholecystitis (n = 25), and gallbladder cancer (n = 18) were reviewed independently by three abdominal radiologists blinded to outcome. The primary outcome was the diagnostic accuracy of MDCT for the differentiation of gallbladder cancer from cholecystitis (acute and xanthogranulomatous) using various imaging parameters. Read More

    Diagnosis of lumbar spinal fractures in emergency department: low-dose versus standard-dose CT using model-based iterative reconstruction.
    Clin Imaging 2018 Apr 14;50:216-222. Epub 2018 Apr 14.
    Department of Orthopedic Surgery, Aerospace Medical Center, 635 Danjae-ro, Namilmyeon, Cheongwon-gun, Chungcheongbuk-do 363-849, Republic of Korea.
    Purpose: To compared the diagnostic performance of low-dose (LD) lumbar-spine (L-spine) CT with that of standard-dose (SD) L-spine CT.
