    • A mobile-phone based high-resolution microendoscope to image cervical precancer 

      Grant, Benjamin D.; Quang, Timothy; Possati-Resende, Júlio César; Scapulatempo-Neto, Cristovam; Matsushita, Graziela de Macedo; Mauad, Edmundo Carvalho; Stoler, Mark H.; Castle, Philip E.; Fregnani, José Humberto Tavares Guerreiro; Schmeler, Kathleen M.; Richards-Kortum, Rebecca (2019)
      Nearly 90% of cervical cancer cases and deaths occur in low- and middle-income countries that lack comprehensive national HPV immunization and cervical cancer screening programs. In these settings, it is difficult to ...
    • Feasibility of transoral robotic-assisted high-resolution microendoscopic imaging of oropharyngeal squamous cell carcinoma 

      Patsias, Alexis; Giraldez-Rodriguez, Laureano A.; Polydorides, Alexandros D.; Richards-Kortum, Rebecca; Anandasabapathy, Sharmila; Quang, Timothy; Sikora, Andrew G.; Miles, Brett A. (2015)
      Background: Transoral robotic-assisted oncologic surgery of the head and neck offers promising functional results. Nonetheless, the efficacy of oncologic surgery remains critically dependent on obtaining negative margins. ...
    • Fluorescence-based endoscopic imaging of Thomsen–Friedenreich antigen to improve early detection of colorectal cancer 

      Sakuma, Shinji; Yu, James Y.H.; Quang, Timothy; Hiwatari, Ken-Ichiro; Kumagai, Hironori; Kao, Stephanie; Holt, Alex; Erskind, Jalysa; McClure, Richard; Siuta, Michael; Kitamura, Tokio; Tobita, Etsuo; Koike, Seiji; Wilson, Kevin; Richards-Kortum, Rebecca; Liu, Eric; Washington, Kay; Omary, Reed; Gore, John C.; Pham, Wellington (2015)
      Thomsen–Friedenreich (TF) antigen belongs to the mucin-type tumor-associated carbohydrate antigen. Notably, TF antigen is overexpressed in colorectal cancer (CRC) but is rarely expressed in normal colonic tissue. Increased ...
    • Low-Cost High-Resolution Microendoscopy for the Detection of Esophageal Squamous Cell Neoplasia: An International Trial 

      Protano, Marion-Anna; Xu, Hong; Wang, Guiqi; Polydorides, Alexandros D.; Dawsey, Sanford M.; Cui, Junsheng; Xue, Liyan; Zhang, Fan; Quang, Timothy; Pierce, Mark C.; Shin, Dongsuk; Schwarz, Richard A.; Bhutani, Manoop S.; Lee, Michelle; Parikh, Neil; Hur, Chin; Xu, Weiran; Moshier, Erin; Godbold, James; Mitcham, Josephine; Hudson, Courtney; Richards-Kortum, Rebecca R.; Anandasabapathy, Sharmila (2015)
      Background & Aims: Esophageal squamous cell neoplasia has a high mortality rate as a result of late detection. In high-risk regions such as China, screening is performed by Lugol’s chromoendoscopy (LCE). LCE has low ...
    • Optical Molecular Imaging in the Gastrointestinal Tract 

      Carns, Jennifer; Keahey, Pelham; Quang, Timothy; Anandasabapathy, Sharmila; Richards-Kortum, Rebecca (2013-05)
      Recent developments in optical molecular imaging allow for real-time identification of morphological and biochemical changes in tissue associated with gastrointestinal neoplasia. This review summarizes widefield and high ...
    • Quantitative Analysis of High-Resolution Microendoscopic Images for Diagnosis of Esophageal Squamous Cell Carcinomaᅠ 

      Shin, Dongsuk; Protano, Marion-Anna; Polydorides, Alexandros D.; Dawsey, Sanford M.; Pierce, Mark C.; Kim, Michelle Kang; Schwarz, Richard A.; Quang, Timothy; Parikh, Neil; Bhutani, Manoop S.; Zhang, Fan; Wang, Guiqi; Xue, Liyan; Wang, Xueshan; Xu, Hong; Anandasabapathy, Sharmila; Richards-Kortum, Rebecca R. (2015)
      Background & Aims: High-resolution microendoscopy is an optical imaging technique with the potential to improve the accuracy of endoscopic screening for esophageal squamous neoplasia. Although these microscopic images can ...
    • Real-time video mosaicing with a high-resolution microendoscope 

      Bedard, Noah; Quang, Timothy; Schmeler, Kathleen; Richards-Kortum, Rebecca; Tkaczyk, Tomasz S. (2012)
      Microendoscopes allow clinicians to view subcellular features in vivo and in real-time, but their field-of-view is inherently limited by the small size of the probe's distal end. Video mosaicing has emerged as an effective ...
