    5. En face optical coherence tomography for diagnosis of unexplained snowflake scotoma

      En face optical coherence tomography for diagnosis of unexplained snowflake scotoma
      Ocular conditions with transitory examination findings can be challenging to diagnose, particularly when significant time has elapsed since the acute insult. One such example is paracentral acute middle maculopathy (PAMM), which may present initially with faint gray macular lesions. These lesions fade over time, leaving behind an unrevealing fundus examination and a pattern of inner nuclear layer (INL) thinning that may be difficult to appreciate with typical imaging modalities. 1 ...

    9. Rapid non-destructive volumetric tumor yield assessment in fresh lung core needle biopsies using polarization sensitive optical coherence tomography

      Rapid non-destructive volumetric tumor yield assessment in fresh lung core needle biopsies using polarization sensitive optical coherence tomography
      Adequate tumor yield in core-needle biopsy (CNB) specimens is essential in lung cancer for accurate histological diagnosis, molecular testing for therapeutic decision-making, and tumor biobanking for research. Insufficient tumor sampling in CNB is common, primarily due to inadvertent sampling of tumor-associated fibrosis or atelectatic lung, leading to repeat procedures and delayed diagnosis. Currently, there is no method for rapid, non-destructive intraprocedural assessment of CNBs. Polarization-sensitive optical coherence tomography (PS-OCT) is ...

  2. About University of Michigan

    University of Michigan

    The University of Michigan, Ann Arbor (UM, U of M or U-M) is a coeducational public research university in the state of Michigan, and one of the foremost universities in the United States. The university was founded in 1817 in Detroit, about 20 years before the territory of Michigan officially became a state, and moved to Ann Arbor in 1837. Today, it is the state's oldest university and the flagship campus of the University of Michigan system, which now has two satellite campuses, the University of Michigan, Flint and the University of Michigan, Dearborn.  In its 2007 edition, U.S. News & World Report ranked the university's undergraduate program 2nd in the United States among public universities and 24th among all universities. In its last published survey in 1995 the National Research Council ranked UM 3rd in the United States in a study that spanned 41 graduate disciplines as to aggregate quality of graduate programs. The university has one of the largest research expenditures of any American university and one of the largest number of living alumni at 420,000. UM also owns one of the most well-regarded academic medical centers in the United States, the University of Michigan Health System. The university is also recognized for its history of student activism and its athletic teams, notably in football, men's basketball, and ice hockey.  Despite being a public institution, the University of Michigan is known for its high student fees; tuition for out-of-state students is currently the most expensive in the country. Also, though the university successfully affirmed before the U.S. Supreme Court that consideration of race as a factor in admissions to universities was constitutional in 2003, Michigan voters approved restrictions on affirmative action in public universities and governmental hiring in November 2006. This forced UM to cease using race and gender as criteria for admissions."
