Ultrasound in Medical Practice

Blog Post By Vicki E. Noble MD, RDMS, FACEP is Director, Division of Emergency Ultrasound, Department of Emergency Medicine, Massachusetts General Hospital and Assistant Professor, Harvard Medical School, Boston, MA, USA.

Over the last 15 years, there has been a seismic shift in how and when ultrasound is used by medical professionals.  Increasingly, physicians, nurse midwives, nurse practitioners and other medical professional staff have started to incorporate bedside diagnostic ultrasound into their patient evaluation (1).  The types of evaluations and the applications specific to different specialty practices vary, but the increasing availability of a bedside diagnostic imaging test has been encouraged by the rapid rate of technology evolution as ultrasound machines have become more portable, cheaper and easier to use.  Read more of this post

Advances in Radiology

Blog Post by Kiat Tsong Tan, Postgraduate Fellow, Department of Radiology and Diagnostic Imaging, University of Alberta, Edmonton, Alberta, Canada.

I never cease to be amazed by the rate of developments in radiology. In the course of the last ten years, radiologists have evolved from doctors who primarily diagnosed disease on one-dimensional x-ray images into technologically savvy individuals deploying the most advanced medical equipment in the battle against disease. The use of computed tomography, magnetic resonance imaging, positron emission tomography and ultrasound has become commonplace. Optical coherence tomography is beginning to emerge as an imaging modality. Organs such as the heart, which were once considered to be inaccessible to cross-sectional imaging, are now easily examined. In addition, the rapid growth of molecular imaging means that we may soon be able to detect disease at its earliest and most fundamental stage, at the level of cellular and molecular biology.

Fellowship of the Royal College of Radiologists Examination part 2B

Blog Post by Jessie Aw, Neuroradiology Fellow at Austin Health, Melbourne, Australia, and  John Curtis, Radiologist Consultant, University Hospital Aintree, Liverpool, University Hospital Aintree, UK

The British summer has arrived and with that, some sunshine. That’s all you need as a radiology registrar who barely sees the sunrays and about to start preparation for the exam. Soak it up, as it should get you enough to get your vitamin D levels up for the rest of the year now the time has come around for the Final Fellowship of the Royal College of Radiologists (FRCR) examination part 2B.

Reducing errors in Abdominal Imaging

Blog Post by Professor Fergus V. Coakley, University of California, San Francisco

The medical literature consistently suggests that 1.0 to 2.6% of radiology reports contain serious errors [1-3]. My experience in clinical practice and running a quality assurance program has convinced me that many of these interpretative mistakes in abdominal imaging are avoidable. Fundamentally, the “pattern recognition” approach that lies at the heart of radiology can be a very powerful diagnostic tool, but also prone to error if different entities look the same.

Essentials of Pediatric Radiology

Do a little bit more than average and from that point on your progress multiplies itself out of all proportion to the effort put in.

Paul J. Meyer

Two types of Radiology textbooks exist: One type is the easily readable, ultrashort book which covers the most basic essentials and permits the reader to “survive” in the field.  The second type is the comprehensive compendium which represents a valuable resource for in depth information on certain topics, but is too extensive to be read from cover to cover. Our book, “Essentials of Pediatric Radiology” attempts to blend these two types by providing a detailed overview of selected topics which are commonly encountered in the daily practice of Pediatric Radiology. Our book is concise enough to be read completely, yet it provides more detailed information compared to other brief textbooks in the field, thereby allowing the reader to acquire more in depth knowledge.  Read more of this post

Painful C1-C2 Facet Arthropathy

Blog Post by H. Gordon Deen, Mayo Clinic, Jacksonville, USA

An often overlooked cause of neck pain is C1 – C2 facet arthropathy.  Patients with this disorder present with severe upper cervical pain which is invariably unilateral on the side of the abnormal facet joint.  Pain is consistently reproduced by cervical extension and by looking over the shoulder on the affected side.

For a variety of reasons, the diagnosis is often missed on MRI.  First, axial MR images are in essentially the same plane as the abnormal facet joint and the cuts may fall immediately above and below the joint, thereby missing the abnormality.  Second, coronal imaging, which is the best way to visualize the upper cervical facet joints, is not routinely done with MR studies of the cervical spine.  And third, bony detail is not seen as well on MR as it is on CT scanning.  Thus, it is not unusual for a patient to undergo several MRI studies without establishing the diagnosis.
