VanDerveer has endured every coach's nightmare throughout the past week. On Saturday, during her team's final regular season game against Oregon Sate, Nygaard, a fifth-year senior, went down in a heap and a subsequent MRI test revealed a ruptured...
Also, Mets right-hander Paul Wilson, who heard a pop in his pitching shoulder Sunday, was cleared to return to the mound by team physician Dr. David Altchek after an MRI showed no structural damage...
...these tools have revolutionized neurosurgery but, just as in his lab work, Black keeps pushing to improve them. He is advising a student, for example, on a project aimed at essentially bringing functional MRI into the operating room in real time. This would permit a surgeon to re-image the brain constantly during surgery in order to observe the changing geography of the brain as the operation progresses. Black is also seeking advances in noninvasive surgery, used when a tumor is so deeply embedded in eloquent tissue that it cannot be cut out. Surgeons now use focused beams...
Instead, Black began to use radio waves, which cook the cancer to death right away. A few years ago, he developed a treatment that uses an MRI-guided radio-wave probe to reach into a tumor. The procedure can be performed under local anesthesia on an outpatient basis and be repeated as needed. Now Black wants to eliminate even this mildly invasive probe with something he calls the MedArray. The prototype, which Black expects to be ready for trials next year, looks like an MRI with microwave antennas lining the chamber. Using the MRI's images, the MedArray computer maps...
This gave scientists a target on which to focus their research. They began scanning that part of the brain with MRI technology, which uses subtle magnetic changes to capture the internal structure of organs in exquisite detail. To their surprise, they discovered that there was on average 39% to 48% less brain tissue in the affected region of depressed patients. Drevets speculates that the deficit may result from the catastrophic loss of a particular subset of brain cells, which his co-workers are trying to identify...
