The escalation of imaging volumes in the emergency department and intensifying demands for rapid radiology results have increased the demand for emergency radiology. The provision of emergency radiology is essential for nearly all radiology practices, from the smallest to the largest. As our radiology specialty responds to the challenge posed by the triple threat of providing 24/7 coverage.
Neuroradiology is a core clinical resource that clearly illustrates and describes MR and CT images of the brain, head and neck, and spine. The text distills the essential aspects of neuroradiology and contains in-depth discussions of imaging findings. Written from a clinical radiology perspective, the content of this book draws on the personal experience of the authors, all of whom are leading experts in neuroradiology.
Fetal and neonatal imaging are topics of interest again this year, including a session on imaging of spinal dysraphisms and the fetal airway. There is also a session with expert discussion of fetal neuro, lung and gastrointestinal cases. The MRI O-RADS interactive session includes a review of each imaging reporting system and a case review.
The chest radiograph is anecdotally thought to be the most frequently-performed radiological investigation globally although no published data is known to corroborate this. UK government statistical data from the NHS in England and Wales shows that the chest radiograph remains consistently the most frequently requested imaging test by GPs. The practice of breast imaging has transitioned through a wide variety of technologic advances from the early days of direct-exposure film mammography to xeromammography to screen-film mammography to the current era of full-field digital mammography and digital breast tomosynthesis.
In the current era of pediatric uroradiology, use of nuclear medicine, ultrasonography, CT, and MRI has been valuable in the identification and management of genitourinary diseases. Excellent information about the renal parenchyma and renal function is currently attainable with current cross-sectional imaging techniques that can identify tissue differentiation of lesions, distinguish dilatation of the pelvocalyceal system, and determine margins of the kidney and perirenal space.
Radiation therapy is an important entity in the treatment of cancer, used alone or in combination with surgery and/or chemotherapy. Research continues to grow in the use of radiation therapy to control cancer, spare surrounding normal tissue, and reduce acute long-term toxicity. Implications for nursing practice: An understanding of radiobiology and physics will assist oncology nurses in providing proper education to the patient and managing radiation-induced side effects.
Molecular imaging provides considerable insight into biological processes for greater understanding of health and disease. Numerous advances in medical physics, chemistry and biology have driven the growth of this field in the past two decades. With exquisite sensitivity, depth of detection and potential for theranostics, radioactive imaging approaches have played a major role in the emergence of molecular imaging.
MR imaging and PET/CT are integrated in the work-up of head and neck cancer patients. The hybrid imaging technology (18)F-FDG-PET/MR imaging combining morphological and functional information might be attractive in this patient population. The aim of the study was to compare whole-body (18)F-FDG-PET/MR imaging and (18)F-FDG-PET/CT in patients with head and neck cancer, both qualitatively in terms of lymph node and distant metastases detection and quantitatively in terms of standardized uptake values measured in (18)F-FDG-avid lesions.
Proton therapy has the ability to deliver a highly conformal dose to tumors. However, localized proton dose deposition at the end of beam (i.e. Bragg peak) comes at the price of significantly greater impact of uncertainties in the treatment plan compared to photon therapy. Range uncertainties may result in under-dosing of the target and/or excess unintended dose to adjacent critical structures.
Clinical radiology is a specialised branch of medicine that uses state of the art equipment and a range of techniques to capture images of the inside of the body. clinical radiologist undertakes an imaging procedure they carefully weigh the benefit against any potential risk.
Forensic radiology is the discipline which comprises the performance, interpretation and reportage of the radiological examinations and procedures which are needed in court procedures or law enforcement. Radiological methods are widely used in identification, age estimation and establishing cause of death.
