Background & Aims: We conducted a study to assess the potential of light-scattering
spectroscopy (LSS), which can measure epithelial nuclear enlargement and crowding, for in situ …

Background: ERCP has become widely available for the diagnosis and treatment of benign
and malignant pancreaticobiliary diseases. In this prospective study, the overall complication …

Diffuse reflectance spectra were collected from adenomatous colon polyps (cancer precursors)
and normal colonic mucosa of patients undergoing colonoscopy. We analyzed the data …

Background & Aims: The aim of this study was to assess the potential of 3 spectroscopic
techniques (fluorescence, reflectance, and light-scattering spectroscopy) individually and in …

Endosonographic features that are thought to characterize lymph node metastasis were
evaluated in 100 patients with esophageal carcinoma. Subjects underwent preoperative …

During the development of neoplasia, epithelial tissues undergo biochemical and structural
changes that can manifest in tissue fluorescence. There have been several reports on …

Background: Endosonography (EUS) is a valuable technique for diagnosing gastrointestinal
stromal cell tumors. However, EUS features that are predictive of malignancy in these …

PURPOSE: This Phase II trial evaluated the toxicity, local control, and overall survival in
patients treated with sequential gemcitabine and linear accelerator–based single-fraction …

Endoscopic diagnosis currently relies on the ability of the operator to visualize abnormal
patterns in the image created by light reflected from the mucosal surface of the gastrointestinal …

Endoscopic imaging is an invaluable diagnostic tool allowing minimally invasive access to
tissues deep within the body. It has played a key role in screening colon cancer and is …
