JF Preface to the Fourth Edition The fourth edition of the Radiology Syllabus is directed towards medical students, non-radiology housestaff, physician assistants, nurse practitioners, radiologist assis- tants and other allied health professionals as a curriculum guide to supplement their radiology education. This book serves only as an introduction to the dynamic fi eld of radiology. In fact, the most diffi cult decision in compiling this fourth edition did not involve what to include, but rather determining what to leave out. The goal of this text is to provide the reader with examples and brief discussions of basic radio- graphic principles that should serve as the foundation for further learning. We hope that it will foster and further stimulate the process at the heart of medical education: self-directed learning. Each edition continues to expand upon the fi rst edition of the photocopied pages and fi lms, written and organized by the original authors, Dr. William Hendrick and Dr. Carlton “Tad” Phelps. As mentors, Dr. Hendrick and Dr. Phelps of Albany Medical Center wanted a curriculum guide to reinforce the teaching concepts of their radiology elective. Dr. Harjit Singh, editor and author of much of the text of the fi rst print edition, formalized the material in 1988. Our third edition, updated by faculty and students at Penn State Hershey was a fi rst effort at organizing and digi- tizing the information for publication. Dr. Marsha Bluto led that conversion of both text and images. Drs. Megan Jenkins and Jonathan Enterline assisted in the multiple rewrites and desktop publishing. Our fourth edition is an effort to expand and reinforce the original authors’ work by 14 new contributors. Dr. Joseph Fotos and Jonathan Douds (MD 2012) are new additions to the writing, illustrating, and editing side. vii Radiology continues to explode in breath and depth. Health practitioners are using radiology studies not just to confi rm a clinical suspicion but to make a diagnosis. We are performing 20 times more CT scans than we did in 1980! From both cost and safety standpoints, clinicians and radiologist need to know what they are doing. We hope this book, used in conjunction with lectures, electives, and discussions, is a start.

  • Rotation: VGH Chest Radiography VGH 899 West 12Th Ave., Vancouver, BC V5Z 1M9
    Rotation: VGH Chest Radiography VGH 899 West 12th Ave., Vancouver, BC V5Z 1M9 Level: PGY 2‐5 Rotation Supervisor: Dr. Ana‐Maria Bilawich During the course of the four years, residents will receive one month of chest radiography training as a junior resident and one month of chest radiography training as a senior resident. Residents are expected to develop graded responsibility as they rise from junior to senior resident level. Each resident will be given guidance at the beginning of a rotation, an interim evaluation will occur mid rotation, and a final evaluation will be given at the end of each rotation. Each final evaluation will be submitted to the residency training program director. All residents are expected to arrive in the department by 0800 hours and stay until the conclusion of the working day. Ongoing teaching and interaction with the staff occurs throughout the day. If a resident is absent from his/her chest plain radiography rotation for any reason, he/she should give ample warning to Dr. Mayo (Chest Section Head) and Dr. Bilawich (rotation supervisor). Vacation and conference requests must be booked with Dr. Mayo and Dr. Bilawich in advance, at least two weeks prior to any planned absence from the rotation. Medical Expert: 1. Basic Science: a) Knowledge of anatomy (PA and lateral chest radiographs) At the end of first Chest radiography rotation, the junior resident (PGY2/3) will demonstrate learning all of the following anatomy on PA and lateral chest radiographs. At the end of the second Chest radiography rotation, the senior resident (PGY4/5) will demonstrate learning all of the following anatomy on PA and lateral chest radiographs.

  • Cardiothoracic Radiology Resident Rotations Academic Year 2016-2017
    Cardiothoracic Radiology Resident Rotations Academic Year 2016-2017 Goals and Objectives based on Core Competencies Introduction: Components of a cardiothoracic radiology curriculum may occur during one or more organ- specific or technology-specific rotations during residency, including rotations in chest radiology, cardiac radiology, pediatric radiology, nuclear medicine, magnetic resonance imaging, computed tomography, fluoroscopy (e.g. sniff test) and interventional radiology (e.g. lung biopsy procedure skills) and include training and experience in plain film interpretation, computed tomography (CT), magnetic resonance imaging (MRI), ultrasonography, angiography, and nuclear radiology examinations related to pulmonary, pleural, mediastinal and cardiovascular disease. Cardiothoracic radiology rotations at DHMC combine chest radiography (CXR) and CT and cardiac CT and MRI. This structure reflects the proposed guidelines for diagnostic radiology core curriculum as laid out by the Residency Restructuring Committee of the Association of Program Directors in Radiology (J Am Coll Radiol 2010;7:507-511) which DHMC Radiology Chair Dr. Jocelyn Chertoff co-authored. Non-cardiac chest MR are typically covered by the Body MR service. Chest interventional procedures, e.g. lung biopsies and pleural fluid drainage, are services provided by Interventional Radiology and Body CT. Body CT also helps read Chest CTs, depending on volumes, but may defer certain CTs to chest imagers based on diagnosis and/or findings that would benefit from cardiothoracic specialist interpretation. General Clinical Responsibilities and Workload: Cardiothoracic radiology at DHMC consists of at least three rotations, usually four weeks in length. During the first rotation, emphasis is primarily on CXR but also with significant exposure to the entire gamut of chest CT examinations.
