Colorectal cancer detection by hyperspectral imaging using fluorescence excitation scanning.

Hyperspectral imaging technologies have shown great promise for biomedical applications. These techniques have been especially useful for detection of molecular events and characterization of cell, tissue, and biomaterial composition. Unfortunately, hyperspectral imaging technologies have been slow to translate to clinical devices - likely due to increased cost and complexity of the technology as well as long acquisition times often required to sample a spectral image.

Hyperspectral imaging fluorescence excitation scanning for colon cancer detection.

Optical spectroscopy and hyperspectral imaging have shown the potential to discriminate between cancerous and noncancerous tissue with high sensitivity and specificity. However, to date, these techniques have not been effectively translated to real-time endoscope platforms. Hyperspectral imaging of the fluorescence excitation spectrum represents new technology that may be well suited for endoscopic implementation.

Hyperspectral Imaging Fluorescence Excitation Scanning for Detecting Colorectal Cancer: Pilot Study.

Optical spectroscopy and hyperspectral imaging have shown the theoretical potential to discriminate between cancerous and non-cancerous tissue with high sensitivity and specificity. To date, these techniques have not been able to be effectively translated to endoscope platforms. Hyperspectral imaging of the fluorescence excitation spectrum represents a new technology that may be well-suited for endoscopic implementation.

Rectal extranodal Rosai-Dorfman disease diagnosed by EUS-FNA: a case report and review of the literature.

Rosai-Dorfman disease (RDD), also known as "sinus histiocytosis with massive lymphadenopathy," only rarely involves the gastrointestinal (GI) tract. Therefore, this unusual site of presentation can be challenging for the pathologist. We present a case of RDD manifesting as a rectal submucosal mass associated with rectal bleeding in a 54 year old woman.

Pulmonary lymphoma of the mucosa-associated lymphoid tissue type: Report of a case with cytological, histological, immunophenotypical correlation, and review of the literature.

A 59-year-old woman presented to The University of South Alabama, Mobile, Ala, with the complaint of shortness of breath. A chest radiograph showed bilateral nodules and interstitial infiltrates. The diagnosis of lymphoma was suggested on bronchial brush smears.
