Overview

The healthcare client was looking for a solution that could address their severe need for effective diagnosis of screening results where the naked human eye could miss the early signs of cancer. They needed a solution that could initially detect screening results and offer an accurate diagnosis. In response, Sparity developed a deep-learning AI model based on convolutional neural networks (CNNs) and deep learning algorithms that are capable of visual object detection, that detect patterns against large datasets of images from both healthy and cancerous tissue and further offers metastasis detection to facilitate a more accurate and efficient diagnosis, saving the patient time and speeding up the treatment.

Challenges

The healthcare client was facing challenges with their current diagnosis and screening approach as trained radiologists can miss evidence in screening results —including high false-positive rates and difficulty predicting treatment success. Furthermore, the manual assessment is prone to subjectivity and sometimes error-prone. As early diagnosis and detection will benefit from potentially curative treatment. The healthcare client needed a solution that could analyze the collected structured data and screening test results in specifically identifying early metastasis in screening mammography, early diabetic retinopathy, colonoscopy, prostate-specific antigen, and cervical cytology.

Solution

Sparity’s healthcare product experts, based on initial requirements, developed a deep-learning AI model with convolutional neural network (CNN) architecture with visual object recognition and detection from whole-slide images from the screening results. The accuracy of various computer vision tasks such as image recognition, object detection, and semantic segmentation is greatly enhanced by the use of CNNs. The deep learning model used an image segmentation approach where images were broken down into multiple segments to make them easier to analyze. The algorithms are trained using a vast database of labelled or pre-identified images and videos of both healthy and cancerous tissue. Furthermore, the deep-learning algorithm searches exhaustively for abnormal patterns and identifies cancer patterns, dramatically reducing the uncertainty of a false negative or missed case of cancer.
