The Radiology of Upper Abdominal Pain


Host: Jason Birnholz, MD   Guest: Dushyant Sahani, MD  Autoimmunity has been identified in over 100 separate diseases. Depending on the target tissues, these disorders may be systemic, localized, or perhaps somewhere in between. The characteristics of autoimmune pancreatitis represent one such example of diffuse-to-localized disorders, and is the subject of this discussion. New forms of imaging enable us to map the inflammatory components of this and other diseases, often identifying conditions that were not part of the original differential diagnosis. How does this both aid and complicate management strategies for patients? Host Dr. Jason Birnholz welcomes Dr. Dushyant Sahani, clinical instructor of radiology at Harvard Medical School and director of CT imaging services at Massachusetts General Hospital, to share insights and expertise on imaging autoimmune pancreatitis.

CT Imaging for Autoimmune Pancreatitis


Guest: Andrea Doria, MD, PhD, MSc   Host: Jason Birnholz, MD  In 1888, William Osler wrote in the Lancet the following: "In patients with suspected acute appendicitis, one should urge towards laparotomy. The indications for surgical interference are not always clear, but in my experience I have been taught that the abdomen is much more frequently left untouched than it should be, and that an operation is too often deferred until practically useless." Clearly, diagnosis of acute appendicitis has come a long way since then. But challenges remain in selecting the safest, most timely, and cost-effective diagnostic modalities for this condition. Dr. Andrea Doria, associate professor in the department of medical imaging at the University of Toronto School of Medicine, clarifies the use of ultrasound versus CT for evaluation of acute appendicitis in children. Dr. Jason Birnholz hosts.

Guest: Scott Holland, PhD   Host: Jason Birnholz, MD   Guest: Daniel Choo, MD  Successful cochlear implantation has remarkable impact on quality of life for children with congenital and early onset hearing loss. How do clinicians best evaluate these children for likelihood of success with implants, and what are the imaging challenges when following up with these patients later on? Drs. Scott Holland and Daniel Choo from the University of Cincinnati examine new technologies on the horizon, from fMRI to near-infrared spectrophotometry, for screening and following candidates of cochlear implantation. In the process, they outline salient features of sensorineural hearing deficits and share the state-of-the-art in operative methods for implantation. Dr. Jason Birnholz hosts.

Guest: Stephanie Wilson, MD, FRCPC   Host: Jason Birnholz, MD  Many clinicians are well familiarized with standard contrast agents such as barium and iodinated compounds to enhance angiographic imaging. Ultrasound, capable of visualizing bloodflow with the use of doppler alone, is yet insufficiently sensitive to capture perfusion of organs and/or tumors at the capillary level. What special kinds of contrast enhancements are needed for ultrasound in this case? Dr. Stephanie Wilson, professor of medical imaging and obstetrics and gynecology at the University of Calgary in Alberta, Canada, discusses the science and art of using micro-bubble contrast agents, and the emergence of contrast-enhanced ultrasound (CEUS) as a safer alternative to traditional angiography. Dr. Jason Birnholz hosts.

Guest: James B. Spies, MD   Host: Jason Birnholz, MD  It's not uncommon for women to report experiencing menstrual changes after having given birth two or more times. These changes include shorter cycles, increased cramping, and heavier bleeding, at times with clots. Such changes are hallmark signs of adenomyosis. Definitive diagnosis of adenomyosis can be made easily with MRI or ultrasound, but are there therapeutic options from interventional radiology as well? If so, can these methods replace hysterectomy? Dr. James Spies, professor of radiology at Georgetown University and chairman of the department of radiology at Georgetown University Medical Center, joins host Dr. Jason Birnholz to resolve these questions.

Medical imaging is an important healthcare topic that impacts physicians in all specialties. Understanding the recent dramatic advances in imaging technology, and their impact on clinical practice is essential for healthcare providers. Advances in Medical Imaging will provide the latest information on imaging topics from renowned experts in the field.

Guest: Fiona Gilbert, MD, MBChB, DMRD   Host: Jason Birnholz, MD   Dr. Fiona Gilbert, Roland Sutton Chair of Radiology at University of Aberdeen Institute of Medical Sciences, discusses her research findings that showed that the rate of breast cancer detection by two experts reading a mammogram was the same as one expert aided by a computer. Dr. Gilbert explains to host Dr. Jason Birnholz that, unlike in the United States, it is normal practice in the United Kingdom for two trained readers to examine mammograms. Tune in to hear how computer-aided detection is likely to improve breast cancer detection in those countries where a single reader is used, as well as improve efficiencies in countries that require two readers.

Host: Beverly Hashimoto, MD   Guest: Beryl Benacerraf, MD  More than amazing images, the utility of three dimensional ultrasound images in obstetrics is expansive, according to guest Dr. Beryl Benacerraf, director of obstetrical ultrasound at Massachusetts General Hospital. Dr. Benacerraf and host Dr. Beverly Hashimoto talk about the ability of volume imaging to capture an image of the uterus from a coronal view, a view that is critical for assessment but could not be obtained through traditional portals of entry prior to 3-D imaging. Dr. Benacerraf also illuminates the diagnostic benefits of other display modalities permitted by volume imaging, such as surface renderings and tomographic cuts.
