    Quality assurance and quantitative imaging biomarkers in low dose CT lung cancer Screening.
    Br J Radiol 2017 Aug 22. Epub 2017 Aug 22.
    Mallinckrodt Institute of Radiology, Washington University School of Medicine, Saint Louis, MO, USA.
    After years of assessment through controlled clinical trials, low-dose CT screening for lung cancer is becoming part of clinical practice. As with any cancer screening test, those undergoing lung cancer screening are not being evaluated for concerning signs or symptoms, but are generally in good health and proactively trying to prevent premature death. Given the resultant obligation to achieve the screening aim of early diagnosis while also minimizing the potential for morbidity from workup of indeterminate but ultimately benign screening abnormalities, careful implementation of screening with conformance to currently recognized best practices and a focus on quality assurance is essential.

    Enhanced radiation dose and DNA damage associated with iodinated contrast media in diagnostic x-ray imaging.
    Br J Radiol 2017 Aug 22:20170028. Epub 2017 Aug 22.
    1 Institute of Health and Society, Newcastle University, Newcastle-upon-Tyne, UK.
    A review was undertaken of studies reporting increased DNA damage in circulating blood cells and increased organ doses, for x-ray exposures enhanced by iodinated contrast media (ICM), compared to unenhanced imaging. This effect may be due to ICM molecules acting as a source of secondary radiation (Auger/photoelectrons, fluorescence x-rays) following absorption of primary x-ray photons.It is unclear if the reported increase in DNA damage to blood cells necessarily implies an increasedrisk of developing cancer.

    1 Department of Radiation Oncology, Centre Hospitalier Lyon Sud, Pierre-Benite, France.
    Objectives: Sexual preservation is an important issue in the treatment of localized prostate cancer. A technique of irradiation was developed to better preserve this function and has been evaluated.

    Methods: Eleven patients, with no erectile dysfunction (ED), were treated with daily IMRTIGRT (total dose: 76-78 Gy). Read More

    Multidetector computedtomography in detection of troublesome posterior sectoral hepatic duct communicating with cystic duct.
    Br J Radiol 2017 Jul 27:20170260. Epub 2017 Jul 27.
    4 Department of Surgery, Applied Life Sciences Institute of Biomedical and Health Sciences, Hiroshima University , Hiroshima , Japan.
    Objective: To investigate whether multiple detector computed tomography (MDCT) could detect troublesome aberrant posterior sectoral hepatic duct (PHD) communicating with cystic duct (CD).

    Methods: The most troublesome bile duct anomaly during cholecystectomy is an aberrant PHD communicating with CD. It has been suggested that an unenhanced small duct between Rouviere's sulcus and CD on MDCT could be coincident to an aberrant PHD communicating with CD. Read More

    Anxiety reduction and emotional self-care using the U technique in radiology departments.

    Department of Nursing, Physiotherapy and Occupational Therapy, Faculty of Occupational Therapy, Speech therapy and Nursing, University of Castilla-La Mancha , Ciudad Real , Spain.
    Daily clinical practice is an important source of stress and emotional exhaustion. In health field, patients could experience a significant number of emotional reactions. There are high levels of anxiety in patients referred for medical imaging, and these levels are even higher in patients undergoing complicated diagnostic procedures. Read More

    Diagnostic value of semiquantitative and quantitative analysis of functional parameters in multiparametric MRI of the prostate.
    Br J Radiol 2017 Jul 27:20170067. Epub 2017 Jul 27.
    3 Department of Diagnostic and Interventional Radiology, University Hospital, Ulm, Germany.
    Objectives: To determine the diagnostic value of semiquantitative and quantitative parameters of three functional techniques in multiparametric (mp)-MRI of the prostate.

    Methods: Mp-MRI was performed in 110 patients with suspicion of prostate cancer (PCA) before TRUS-guided core biopsy. Peak-enhancement, initial and post-initial enhancement, iAUGC (initial area under gadolinium curve), Ktrans (forward rate constant), Kep (efflux rate constant), Ve (extracellular volume), ADC (apparent diffusion coefficient), and MR spectroscopy ratio were obtained for malignant and benign lesions.

    Ablative safety margin depicted by fusion imaging with post-treatment contrast-enhanced ultrasound and pre-treatment CECT/CEMRI after radiofrequency ablation for liver cancers.
    Br J Radiol 2017 Jul 27:20170063. Epub 2017 Jul 27.
    Department of Medical Ultrasound, Shanghai Tenth People's Hospital, Ultrasound Research and Education Institute, Tongji University School of Medicine , Shanghai , China.
    Objectives: To evaluate the value of fusion imaging with post-treatment contrast-enhanced ultrasound (CEUS) and pre-treatment contrast-enhanced computed tomography/magnetic resonance imaging (CECT/CEMRI) in evaluating ablative safety margin after percutaneous ultrasound (US)-guided radiofrequency ablation (RFA) for liver cancers.

    Methods: 34 consecutive patients with 47 liver lesions who had undergone RFA were included. Fusion imaging with post-treatment CEUS and pre-treatment CECT/CEMRI was carried out to evaluate local treatment response and ablative safety margin within 1-3 days after RFA. Read More

    Impact of robotic ultrasound image guidance on plan quality in SBRT of the prostate.
    Br J Radiol 2017 Jul 27:20160926. Epub 2017 Jul 27.
    1 Institute of Medical Technology, Hamburg University of Technology, Hamburg, Germany.
    Objectives: Ultrasound provides good image quality, fast volumetric imaging, and is established for abdominal image guidance. Robotic transducer placement may facilitate intra-fractional motion compensation in radiation therapy. We consider integration with the CyberKnife and study whether the kinematic redundancy of a seven-degrees-of-freedom robot allows for acceptable plan quality for prostate treatments. Read More

    Distribution and chemical forms of gadolinium in the brain: A review.
    Br J Radiol 2017 Jul 27:20170115. Epub 2017 Jul 27.
    1 Department of Radiology, Teikyo University School of Medicine, Tokyo, Japan.
    In the 3 years since residual gadolinium-based contrast agent (GBCA) in the brain was first reported, much has been learned about its accumulation, including the pathway of GBCA entry into the brain, the brain distribution of GBCA, and its excretion. Here we review recent progress in understanding the routes of gadolinium deposition in brain structures. Read More

    Development of a paediatric head voxel model database for dosimetric applications.
    Br J Radiol 2017 Jul 27:20170051. Epub 2017 Jul 27.
    1 Department of Imaging and Pathology, Faculty of Medicine, Katholieke Universiteit Leuven, Leuven, Belgium.
    Objectives: To develop a database of paediatric head voxel models intended for Monte Carlo (MC) dosimetric applications.

    Methods: Seventeen head and neck CT image datasets were retrieved from the Picture Archiving and Communicating System (PACS) of our hospital and were reformed into voxel models. Twenty two organs were segmented at each dataset. Read More

    Uncommon Neoplasms of the biliary tract: Radiological Findings.
    Br J Radiol 2017 Jul 21:20160561. Epub 2017 Jul 21.
    1 Department of Radiology, Istituto Nazionale Tumori IRCCS Fondazione Pascale, IRCCS di Napoli, Naples, Italy.
    Objectives: To report our cancer center experience in the biliary tumors incidence other than cholangiocellular-carcinoma (CCC), emphasizing the radiological features.

    Methods: 197 patients with biliary disease undergoing Gd-EOB-DTPA-enhanced MRI were reviewed. Four radiologists evaluated retrospectively size, structure, anatomical site, and signal intensity of lesions on MRI. Read More
