Histopathologic Validation of Intracoronary Ultrasound Imaging

Journal of the American Society of Echocardiography, 1994
The purpose of this study was to validate intracoronary ultrasound imaging by correlation with histologic examination. In this in-vitro study of pressure-perfused human coronary arteries, 104 matching intracoronary ultrasound imaging images and histologic cross-sections from 12 hearts were compared to determine the diagnostic accuracy of 30 MHz ...

MALDI imaging in histopathology

Pathology, 2014
Introduction MALDI imaging is a new technique that allows the investigation of the molecular signatures directly on tissue sections. The technology allows for the quantification of pep-tides/proteins and their spatial distributed on these tissues. The technology has tremendous potential for the discovery of new biomarkers in cancer. The primary aim of

Identifying Cells in Histopathological Images

2010
We present an image analysis pipeline for identifying cells in histopathology images of cancer. The analysis starts with segmentation using multi-phase level sets, which is insensitive to initialization and enables automatic detection of arbitrary objects. Morphological operations are used to remove small spots in the segmented images. The target cells

Leiomyosarcoma of sacrum: imaging and histopathologic findings

European Radiology, 2002
A rare case of low-grade primary leiomyosarcoma of the sacrum is described in a young woman who suffered from pain in the right sacroiliac region. A lytic sacral mass was observed on conventional radiology and CT studies. Magnetic resonance imaging clearly showed Gd-DTPA enhancement in the entire mass demonstrating its hypervascularity, which was later

Efficient nucleus detector in histopathology images

Journal of Microscopy, 2012
SummaryIn traditional cancer diagnosis, (histo)pathological images of biopsy samples are visually analysed by pathologists. However, this judgment is subjective and leads to variability among pathologists. Digital scanners may enable automated objective assessment, improved quality and reduced throughput time.

Evaluation of Hyperbolic Attention in Histopathology Images

2020 IEEE 20th International Conference on Bioinformatics and Bioengineering (BIBE), 2020
We bring together into a common framework three key ideas — multi-scale medical image analysis, the attention mechanism, and hyperbolic embeddings. The formulation and evaluation of hyperbolic-attention models for multi-scale medical image analysis have not been previously explored.

The Adrenal Mass: Correlation of Histopathology with Imaging

Annals of Surgical Oncology, 2009
Computed tomography (CT) and magnetic resonance (MR) imaging can help diagnose benign adrenal adenomas, but prior studies rely on nonoperative follow-up as proof of a lesion's benign nature. We examined adrenalectomy tissues to determine if imaging characteristics correlate with histopathologic findings.We retrieved data for 196 consecutive ...

Meniere's disease: histopathology, cytochemistry, and imaging

Annals of the New York Academy of Sciences, 2015
Meniere's disease is a poorly understood, disabling syndrome causing spells of vertigo, hearing fluctuation, tinnitus, and aural fullness. In this paper, we present a review of the histopathology, cytochemistry, and imaging of Meniere's disease. Histopathology is significant for neuroepithelial damage with hair cell loss, basement membrane thickening ...

Tumor Tissue Segmentation for Histopathological Images

Proceedings of the ACM Multimedia Asia, 2019
Histopathological image analysis is considered as a gold standard for cancer identification and diagnosis. Tumor segmentation for histopathological images is one of the most important research topics and its performance directly affects the diagnosis judgment of doctors for cancer categories and their periods.

Calciphylaxis: Comparison of radiologic imaging and histopathology

Journal of the American Academy of Dermatology, 2017
The current gold standard for diagnosis of calciphylaxis is a skin biopsy specimen demonstrating calcification of small-caliber arteries or arterioles.The aim of this study is to compare diameters of calcified vessels seen in skin biopsy specimens and radiology images of patients with calciphylaxis.We conducted a retrospective study of patients with ...
