  • Utility of 3-D Ultrasound Volume Imaging in Obstetrics and Gynecology

    Jul 7, 2014 | 16 min
    Hosted by: Beverly Hashimoto Guest: Beryl Benacerraf 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.    
  • Pediatric Musculoskeletal Infections: The Role of MRI

    Jun 2, 2014 | 15 min
    Hosted by: Jason Birnholz Guest: J. Herman Kan Pre-treatment MRI can eliminate unnecessary diagnostic or surgical procedures for children with suspected musculoskeletal infections. Host Dr. Jason Birnholz and Dr. J. Herman Kan, assistant professor of radiology at Vanderbilt University Medical Center, specializing in pediatric and adolescent radiology, discuss the application of MRIs and the results of his recent study which showed that a significant number of surgeries could be avoided with early MRI evaluation. Tune in to hear the valuable role MRI plays in the evaluation of musculoskeletal infection. 
  • Radiological Services in the Third World

    May 26, 2014 | 15 min
    Hosted by: Beverly Hashimoto Guest: Sharlene Teefey Dr. Sherry Teefey, professor of radiology at Washington University School of Medicine in St. Louis, discusses with host Dr. Beverly Hashimoto her experience in Bhutan and Uganda, teaching medical professionals how to use ultrasound and computed tomography and enhancing current techniques. Tune in to hear the challenges to providing imaging services in these countries and the future goals to introduce new modalities and improve radiological services in third world countries.
  • Ultrasound in the Evaluation of Abnormal Vaginal Bleeding

    Mar 10, 2014 | 15 min
    Hosted by: Beverly Hashimoto Guest: Dawna Kramer Although most abnormal vaginal bleeding is caused by hormone imbalance, it can be indicative of polyps, myomas, and cancers of the cervix and endometrium. Dr. Dawna Kramer, a radiologist within the department of radiology, ultrasound section at the Virginia Mason Medical Center in Seattle, discusses with host Dr. Beverly Hashimoto several ultrasound techniques, including sonohysterography, for determining the cause of post- and pre-menopausal vaginal bleeding.
  • Radiologic Diagnosis of Breast Cancer

    Jan 20, 2014 | 15 min
    Hosted by: Beverly Hashimoto Guest: Dawna Kramer Have new techniques changed the long-standing paradigm of breast cancer detection by mammogram? Dr. Dawna Kramer, radiology quality assurance officer and section head of the patient access area in the radiology department at the Virginia Mason Medical Center in Seattle, talks with host Dr. Beverly Hashimoto about the applications and inter-relationship of mammography and breast ultrasound in the diagnosis of breast masses. Dr. Kramer highlights the reasons mammography continues to account for the majority of breast mass detections. What are the benefits of digital mammogram and what is the usefulness of breast ultrasound and MRI?  
  • Musculoskeletal Ultrasound Applications

    Aug 6, 2012 | 15 min
    Hosted by: Beverly Hashimoto Guest: Sharlene Teefey Ultrasound images of the musculoskeletal system provides pictures of muscles, tendons, ligaments, joints and soft tissue throughout the body. Dr. Sherry Teefey, associate professor of radiology at Washington University School of Medicine in St. Louis, discusses with host Dr. Beverly Hashimoto some of the common uses for this procedure. Dr. Teefey also discusses the application of musculoskeletal ultrasound in conjunction with aspiration or injection. Tune in to hear the benefits and limitations of diagnostic musculoskeletal ultrasound.
  • Cost and Risk Analysis for Imaging of Acute Appendicitis in Children

    Feb 20, 2012 | 15 min
    Hosted by: Jason Birnholz Guest: Andrea Doria 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 ...
  • State of the Art in Cochlear Implantation Imaging

    Feb 6, 2012 | 16 min
    Hosted by: Jason Birnholz Guests: Scott Holland, Daniel Choo 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...
  • A Closer Look at Thyroid Ultrasound

    Jan 23, 2012 | 15 min
    Hosted by: Beverly Hashimoto Guest: Jonn Cronan Thanks to extremely sensitive ultrasound technology, thyroid nodules are being detected and treated at unprecedented rates. Host Dr. Beverly Hashimoto welcomes Dr. John Cronan, professor of diagnostic imaging at the Brown University School of Medicine and chairman of the diagnostic imaging department at Rhode Island Hospital, to discuss the phenomenon of over-treatment of thyroid nodules. Is this pattern of care helping or harming our patients?  
  • The Science and Art of Micro-Bubble Contrast Agents

    Dec 19, 2011 | 15 min
    Hosted by: Jason Birnholz Guest: Stephanie Wilson 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 ...
  • Treating Adenomyosis: Alternatives to Hysterectomy

    Sep 19, 2011 | 15 min
    Hosted by: Jason Birnholz Guest: James B. Spies 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 ...
  • The Radiology of Upper Abdominal Pain

    Sep 12, 2011 | 16 min
    Hosted by: Jason Birnholz Guest: Dushyant Sahani More often, the diagnosis of causes of upper abdominal pain and specialty triage of patients as necessary has become the province of the radiologist. How do radiologists best approach diagnosis and management for these patients, and what factors underlie positive interactions between referring physician and radiologist for this common clinical problem? Host Dr. Jason Birnholz is joined by Dr. Dushyant Sahani, clinical instructor of radiology at Harvard Medical School and director of CT imaging services at Massachusetts General Hospital, to examine the radiology of upper abdominal pain and the expanding role of the radiologist.
