    14 Aug 2014 | 8:01 am
    BACKGROUND AND PURPOSE: Brain injury is a major complication in neonates with complex congenital heart disease. Preliminary evidence suggests that fetuses with congenital heart disease are at greater risk for brain abnormalities. However, the nature and frequency of these brain abnormalities detected by conventional fetal MR imaging has not been examined prospectively. Our primary objective was to determine the prevalence and spectrum of brain abnormalities detected on conventional clinical MR imaging in fetuses with complex congenital heart disease and, second, to compare the congenital…
  • Functional Anatomy of Essential Tremor: Lessons from Neuroimaging [REVIEW ARTICLES]

    Klaming, R., Annese, J.
    14 Aug 2014 | 8:01 am
    SUMMARY: The neuropathogenetic processes underlying essential tremor appear to cause subtle morphologic changes in neural networks that include multiple brain structures, primarily the cerebellum, brain stem, frontal lobes, and thalamus. One of the main challenges of neuroimaging in essential tremor is differentiating disease-specific markers from the spectrum of structural changes that occur due to aging. This review discusses recent neuroimaging studies in the light of current knowledge of the neuropsychology and pathology of the disease. We suggest that the application of multiple…

    Hennie Verburg
    26 Aug 2014 | 5:00 pm
    Background: In total knee arthroplasty (TKA), cement penetration between 3 and 5 mm beneath the tibial tray is required to prevent loosening of the tibia component. The objective of this study was to develop and validate a reliable in vivo measuring technique using CT imaging to assess cement distribution and penetration depth in the total area underneath a tibia prosthesis. Methods: We defined the radiodensity ranges for trabecular tibia bone, polymethylmethacrylate (PMMA) cement and cement-penetrated trabecular bone and measured the percentages of cement penetration at various depths after…
  • Masked smoothing using separable kernels for CT perfusion images

    David Wack
    20 Aug 2014 | 5:00 pm
    Background: CT perfusion images have a high contrast ratio between voxels representing different anatomy, such as tissue or vessels, which makes image segmentation of tissue and vascular regions relatively easy. However, grey and white matter tissue regions have relatively low values and can suffer from poor signal to noise ratios. While smoothing can improve the image quality of the tissue regions, the inclusion of much higher valued vascular voxels can skew the tissue values. It is thus desirable to smooth tissue voxels separately from other voxel types, as has been previously implemented…
  • The use of PET-MRI in the follow-up after radiofrequency- and microwave ablation of colorectal liver metastases

    Karin Nielsen
    7 Aug 2014 | 5:00 pm
    Background: Thermal ablation of colorectal liver metastases (CRLM) may result in local progression, which generally appear within a year of treatment. As the timely diagnosis of this progression allows potentially curative local treatment, an optimal follow-up imaging strategy is essential. PET-MRI is a one potential imaging modality, combining the advantages of PET and MRI. The aim of this study is evaluate fluorine-18 deoxyglucose positron emission tomography (FDG) PET-MRI as a modality for detection of local tumor progression during the first year following thermal ablation, as compared to…
  • Diffusion-weighted MRI characteristics of the cerebral metastasis to brain boundary predicts patient outcomes

    Rasheed Zakaria
    2 Aug 2014 | 5:00 pm
    Background: Diffusion-weighted MRI (DWI) has been used in neurosurgical practice mainly to distinguish cerebral metastases from abscess and glioma. There is evidence from other solid organ cancers and metastases that DWI may be used as a biomarker of prognosis and treatment response. We therefore investigated DWI characteristics of cerebral metastases and their peritumoral region recorded pre-operatively and related these to patient outcomes. Methods: Retrospective analysis of 76 cases operated upon at a single institution with DWI performed pre-operatively at 1.5T. Maps of apparent diffusion…

    Nicholas Marston
    10 Aug 2014 | 5:00 pm
    Background: Impaired left ventricular diastolic filling is common in chronic thromboembolic pulmonary hypertension (CTEPH), and recent studies support left ventricular underfilling as a cause. To investigate this further, we assessed left atrial volume index (LAVI) in patients with CTEPH before and after pulmonary thromboendarterectomy (PTE). Methods: Forty-eight consecutive CTEPH patients had pre- & post-PTE echocardiograms and right heart catheterizations. Parameters included mean pulmonary artery pressure (mPAP), pulmonary vascular resistance (PVR), cardiac index, LAVI, & mitral…

  • Percutaneous Sclerotherapy of a Fingertip High-Flow Arteriovenous Malformation with Ethanol plus Lipiodol

    Nobuyuki Kawai, Morio Sato, Hiroki Minamiguchi, Akira Ikoma, Hiroki Sanda, Motoki Nakai, Tetsuo Sonomura
    31 Aug 2014 | 5:00 pm
    It is difficult to eradicate high-flow arteriovenous malformations (AVMs) safely, and the treatment options are very challenging (1–4). A 60-year-old woman presented with a fingertip high-flow AVM (Fig, a). Although she previously underwent surgical ligation, the size of the AVM and pain gradually increased. She underwent embolization with N-butyl cyanoacrylate, which had no effect on the size of the AVM. Percutaneous sclerotherapy with a mixture of ethanol plus ethiodized oil (Lipiodol; Guerbet, Roissy, France) was performed 1 week later.

    An 83-year-old man with a 5-cm abdominal aortic aneurysm with extension into the bilateral common iliac arteries underwent endovascular aneurysm repair with an AFX Endovascular AAA System (Endologix, Irvine, California). The distal end of an extension limb deployed in the left common iliac artery would not fully expand (Fig 1, arrowheads). Angiography revealed the graft terminating beyond the intended landing zone, partially covering the origin of the internal iliac artery, which was dominant, and resulting in decreased flow (Fig 1).
  • Hook, Line, and Sinker: Hook Wire Localization of a Retained Suture Needle in the Perineum

    31 Aug 2014 | 5:00 pm
    Despite efforts to minimize the incidence of retained surgical instruments, this complication continues to occur in approximately 1 in 8,000–18,000 of all operations (1). Preoperative localization of breast lesions with a hook wire has become a standard radiologic practice (2). This technique is advantageous because the needle is accurately positioned under imaging guidance, and when deployed, the hook maintains the wire in position until the patient can undergo surgical resection of the suspicious lesion.

  • Dysfunctional involvement of emotion and reward brain regions on social decision making in excess weight adolescents

    Antonio Verdejo-García, Juan Verdejo-Román, Jacqueline S. Rio-Valle, Juan A. Lacomba, Francisco M. Lagos, Carles Soriano-Mas
    28 Aug 2014 | 9:47 pm
    Abstract Obese adolescents suffer negative social experiences, but no studies have examined whether obesity is associated with dysfunction of the social brain or whether social brain abnormalities relate to disadvantageous traits and social decisions. We aimed at mapping functional activation differences in the brain circuitry of social decision making in adolescents with excess versus normal weight, and at examining whether these separate patterns correlate with reward/punishment sensitivity, disordered eating features, and behavioral decisions. In this fMRI study, 80 adolescents aged 12 to…
  • Nonphysiological factors in navigated TMS studies; Confounding covariates and valid intracortical estimates

    Sein Schmidt, Rouven Bathe-Peters, Robert Fleischmann, Maria Rönnefarth, Michael Scholz, Stephan A. Brandt
    28 Aug 2014 | 9:47 pm
    Abstract Brain stimulation is used to induce transient alterations of neural excitability to probe or modify brain function. For example, single-pulse transcranial magnetic stimulation (TMS) of the motor cortex can probe corticospinal excitability (CSE). Yet, CSE measurements are confounded by a high level of variability. This variability is due to physical and physiological factors. Navigated TMS (nTMS) systems can record physical parameters of the TMS coil (tilt, location, and orientation) and some also estimate intracortical electric fields (EFs) on a trial-by-trial basis. Thus, these…
  • Cognitive impairment and resting-state network connectivity in Parkinson's disease

    26 Aug 2014 | 10:28 pm
    Abstract This study was conducted to examine the statistical influence of brain size on cortical, subcortical, and cerebellar compartmental volumes. This brain size influence was especially studied to delineate interactions with Sex and Age. Here, we studied 856 healthy subjects of which 533 are classified as young and 323 as old. Using an automated segmentation procedure cortical (gray and white matter [GM and WM] including the corpus callosum), cerebellar (GM and WM), and subcortical (thalamus, putamen, pallidum, caudatus, hippocampus, amygdala, and accumbens) volumes were measured and…
  • Right prefrontal and ventral striatum interactions underlying impulsive choice and impulsive responding

    Brendan Behan, Adam Stone, Hugh Garavan
    26 Aug 2014 | 5:09 am
    Abstract Although a multifaceted concept, many forms of impulsivity may originate from interactions between prefrontally-mediated cognitive control mechanisms and limbic, reward or incentive salience approach processes. We describe a novel task that combines reward and control processes to probe this putative interaction. The task involves elements of the monetary incentive delay task (Knutson et al., [2000]: Neuroimage 12:20–27) and the Go/No-Go task (Garavan et al., [1999]: Neuroimage 17:1820–1829) and requires human subjects to make fast responses to targets for financial reward but to…

    Hizuru Osanai, Hiroko Kuroiwa, Keiichi Uchida, Hideaki Kagami, Kazuhiro Yamada, Akira Taguchi
    25 Aug 2014 | 11:20 pm
    ABSTRACT PurposeWe investigated whether there was any association between age, sex, and body mass index (BMI) and nodal morphology and vascular pattern in healthy young Japanese adults. MethodsThree neck regions in 100 healthy subjects, 19–40 years old, were examined by gray-scale and color Doppler sonography. Vascular pattern was classified into three groups: avascular, hilar, or scattered. A linear mixed-effect model was used to identify associations of age, sex, or BMI with the short-axis diameter and the short-to-long axis diameter ratio (S/L). A cumulative link mixed model was used to…

  • Intraoperative ultrasound to facilitate removal of a submucosal foreign body

    Matthew E. Smith, Faruque Riffat, Laurence H. Berman, Piyush Jani
    22 Aug 2014 | 4:02 am
    ABSTRACT A 61-year-old man with a history of fish bone ingestion and poorly localized symptoms was seen. His clinical examination was unremarkable, but CT demonstrated a foreign body deeply embedded within his tongue. Intraoperative ultrasound (US) guidance facilitated identification of a bone, allowing a needle to be placed as a guide to dissection. Repeat US scanning through the incision permitted precisely targeted surgery. CT and US are the most effective imaging techniques for localizing fish bones. Intraoperative US can be used to accurately locate a submucosal fish bone in mobile…
