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.

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?

Dr. Theodore Dubinksy reviews the conventional use of ultrasound imaging to detect and diagnose thyroid nodules, including fine needle biopsies. He then explains how ultrasound elastography, a newly developed technique, to analyze the stiffness of non-palpable nodules by measuring the amount of distortion from the carotid artery, an highlights the results of this method, as well as the potential for this technique to replace fine needle aspirations as a means for diagnosing thyroid nodules. Dr. Jason Birnholz hosts.

Host: Michael Greenberg, MD

Hypertrophic cardiomyopathy (HCM) is the leading cause of sudden death in young athletes. Joining host Dr. Michael Greenberg to discuss HCM is Dr. Martin Maron, director of the Hypertrophic Cardiomyopathy Center and co-director of cardiac MRI and CT at Tufts Medical Center. As an imaging specialist, Dr. Maron utilizes cardiac MRI and cardiac CT for the evaluation and treatment of patients. Discussing all aspects of HCM, Dr. Maron and Dr. Greenberg address this most common of all genetic cardiac diseases (occurring in 1/500 individuals), invasive and non-invasive treatment, and implications for HCM patients involved in sports.

In surgery, we strive for less invasive procedures that still allow for the greatest precision possible. Developments in image-guided surgery are helping us meet this goal. Dr. Craig Israelite, assistant professor of orthopedic surgery at the University of Pennsylvania Health System, joins host Dr. Lee Freedman to discuss computer-assisted tools for surgery. How has the field evolved since its inception ten years ago? What are the key risks or drawbacks to consider with this technology?

Host: Larry Kaskel, MD

Guest: John Cantwell, MD

"If cost were not an issue, all athletes should have a mandatory baseline EKG and a limited echocardiogram," says our guest Dr. John Cantwell, cardiologist with Cardiology of Georgia P.C. and sports physician for Georgia Tech and the Atlanta Braves. He would even apply these standards to high school athletes. In this segment, Dr. Cantwell and host Dr. Larry Kaskel explore the causes of sudden cardiac death and discuss prevention measures in professional, collegiate and amateur athletes.

What's around the bend for radiation targeting systems? Dr. Charles Enke, professor and chair of radiation oncology at the University of Nebraska College of Medicine, speaks with host Dr. Gary Kohn about the potential of electromagnetic targeting and tracking as used in the GPS-like Calypso-guided technology. Detecting prostate motion in real-time, eliminating inter-observer variation, and providing the benefit of more precise radiation targeting are, as Dr. Enke mentions, just a few of the benefits with this new technology.

Keeping closer tabs on the intrafractional movement of the prostate during radiation therapy will continue to play an increasingly significant role in improving our overall success when treating prostate cancer. So says Dr. Charles Enke, professor and chair of radiation oncology at the University of Nebraska College of Medicine. He details the latest in prostate imaging with host Dr. Gary Kohn. How are we enhancing our command of real-time monitoring modalities?

Host: Jay Goldstein, MD

Guest: Don Rockey, MD

CT colonography has been touted as a less invasive and lower-risk alternative to traditional screening colonoscopy. When considering accuracy and test functionality, do the realities match the acclaim? Host Dr. Jay Goldstein speaks with Dr. Don Rockey, professor of internal medicine and chief of digestive and liver diseases at the University of Texas Southwestern Medical School, about the practicalities of CT colonography and its potential role in colorectal cancer screening.

Host: Bruce Bloom, DDS, JD

Guest: Walter Stadler, MD

In 1971 Dr. Judah Folkman announced to the world that angiogenesis would be the Achilles heel of cancer-what's happened in the last 35 years? Dr. Walter M. Stadler, professor of medicine, director of Genitourinary Program, and associate dean of Clinical Research at the University of Chicago Medical Center joins host Dr. Bruce Bloom to fast forward from that early discovery to the current cutting edge uses for Avastin and other anti-angiogenics in cancer, including successes and shortcomings of this class of drugs in treating both solid tumors and blood cancers .
