Guest: David Felson, MD, MPH

A patient in your office describes the knee pain they have been feeling for an extended period of time. The MRI that you order on their knee reveals meniscal damage. New research is telling us that meniscal tears may be more common than we realize, and further, raises questions as to whether the meniscal tear is really the source of your patient's knee pain. Dr. David Felson, professor of medicine at the Boston University (BU) School of Medicine and professor of epidemiology at the BU School of Public Health, explains that damaged meniscal cartilage may not be directly linked to knee pain. Dr. Mark Nolan Hill hosts.

Developments in ultrasound technologies yield superior image quality. But these new technologies are also designed to maximize information density– minimizing acquisition time, decreasing analysis time, and simplifying reporting. Dr. Roee Lazebnik, a radiologist with a PhD in biomedical engineering, employed by Siemens Healthcare, explains to host Dr. Jason Birnholz how the new ultrasound imaging equipment gives greater information density by increasing the amount of clinical information derived from an image.

Host: Beverly Hashimoto, MD

Guest: Vicki Noble, MD

Dr. Vicki Noble, director of the Division of Emergency Ultrasound at Massachusetts General Hospital in Boston, discusses with host Dr. Beverly Hashimoto the importance of ultrasound in the critical care setting. In the emergency department, ultrasound can improve the physican's ability to administer appropriate treatment during the crucial "golden hour" of trauma. Dr. Noble also discusses six additional applications for ultrasound in the emergency department.

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.

Host: Roy Levit, MD

Dr. Richard Rosen, surgeon director for the department of ophthalmology and director of ophthalmic research in the Advanced Imaging Center at New York Eye and Ear Infirmary, joins host Dr. Roy Levit to discuss technologies and methods to examine the retina.

Guest: Brian Garra, MD

Ultrasound elastography, or tissue strain imaging, can provide real-time quantitative analysis on deep tissue and small nodules that elude palpation. Dr. Brian Garra, professor and vice chair of radiology at the University of Vermont College of Medicine, discusses with host Dr. Jason Birnholz, what makes this method of imaging like “palpation on steroids.” How can elastography technology help catch disease in its earliest stages, and in some cases even make biopsy unnecessary?

Guest: Eyal Herzog, MD, FACC

So small, it is called the ‘pocket ultrasound,' Dr. Eyal Herzog, director of the cardiac care unit at St. Luke's-Roosevelt Hospital Center in New York, discusses with host Dr. Jason Birnholz the results of his research on the handheld portable ultrasound unit in the cardiac care department. Dr. Herzog reports no significant differences in image quality compared to the larger, high-end machine. The portability of the handheld has the capacity to improve care by increasing the speed at which we can assess critically ill patients.

Host: Mark DeLegge, MD

Guest: Thomas D. Wang, MD, PhD

Microscopic imaging of the digestive tract moves beyond examination of tissue at subcellular levels, helping us identify molecular regions in which to probe for dysplasia. Dr. Thomas Wang, assistant professor of medicine and biomedical engineering at the University of Michigan Medical School, details this 'biopsy inside the body' with host Dr. Mark DeLegge. How could this technology shape the future of GI practice? How does this differ from chromoendoscopy, autofluorescence, and other current technologies?

Host: Jason Birnholz, MD

Guest: Mani Vannan, MBBS

Dr. Mani Vannan, professor of clinical internal medicine at the Ohio State University College of Medicine, reports how the latest ultrasound technology has dramatically improved echocardiography by enabling the acquisition of a full volume image in one heartbeat. In addition, the new technology of the ultrasound equipment produces meaningful output information from the image. Dr. Vannan also explains to host Dr. Jason Birnholz the practical implications these enhancements have in terms of diagnosing cardiovascular conditions and enhancing workflow productivity.

Host: Lisa Mazzullo, MD

Guest: Wendie Berg, MD, PhD

The number of women affected by breast cancer every year is staggering: almost 180,000 new cases and upwards of 40,000 deaths. Researchers are focused on finding novel ways to detect a malignancy before it spreads-to the lymph nodes and beyond. Dr. Wendie Berg, a breast imaging radiologist associated with the Johns Hopkins University School of Medicine, talks with host Dr. Lisa Mazzullo about her latest work: studying the use of ultrasound, in conjunction with mammography, to detect breast cancer in high-risk women.
