“…To segment our color fundus images, we trained and tested a U-Net multi-class segmentation model on 200 labeled retinal images (Figure 1). U-Net [30] has become a widely known medical image segmentation technique and has demonstrated excellent performance as a fully convolutional neural network [3,30]. The U-Net architecture contains two "paths."…”

“…Diabetic retinopathy is a small-vessel consequence of diabetes and continues to be the leading cause of preventable ocular morbidity amongst working aged individuals. Diabetes currently affects 422 million people globally, with 600 million people expected to be impacted by 2040, primarily in low-and middle-income nations [3]. It is found in one-third of diabetics and it is related to a higher risk of life-threatening systemic vascular problems such as small vessels heart disease, cardiac failure, and stroke [4].…”

“…These methods have the ability to be used in every aspect of medical practice, thanks to recent breakthroughs in digital data acquisition. They are moving into fields that were previously regarded as being entirely the domain of humans, and ophthalmology is no exception [3]. Every year, medical caravans visit many remote areas of Morocco to treat patients.…”

Diabetic retinopathy (DR) remains one of the world’s frequent eye illnesses, leading to vision loss among working-aged individuals. Hemorrhages and exudates are examples of signs of DR. However, artificial intelligence (AI), particularly deep learning (DL), is poised to impact nearly every aspect of human life and gradually transform medical practice. Insight into the condition of the retina is becoming more accessible thanks to major advancements in diagnostic technology. AI approaches can be used to assess lots of morphological datasets derived from digital images in a rapid and noninvasive manner. Computer-aided diagnosis tools for automatic detection of DR early-stage signs will ease the pressure on clinicians. In this work, we apply two methods to the color fundus images taken on-site at the Cheikh Zaïd Foundation’s Ophthalmic Center in Rabat to detect both exudates and hemorrhages. First, we apply the U-Net method to segment exudates and hemorrhages into red and green colors, respectively. Second, the You Look Only Once Version 5 (YOLOv5) method identifies the presence of hemorrhages and exudates in an image and predicts a probability for each bounding box. The segmentation proposed method obtained a specificity of 85%, a sensitivity of 85%, and a Dice score of 85%. The detection software successfully detected 100% of diabetic retinopathy signs, the expert doctor detected 99% of DR signs, and the resident doctor detected 84%.

The identification and characterization of lung diseases is one of the most interesting research topics in recent years. They require accurate and rapid diagnosis. Although lung imaging techniques have many advantages for disease diagnosis, the interpretation of medial lung images has always been a major problem for physicians and radiologists due to diagnostic errors. This has encouraged the use of modern artificial intelligence techniques such as deep learning. In this paper, a deep learning architecture based on EfficientNetB7, known as the most advanced architecture among convolutional networks, has been constructed for classification of medical X-ray and CT images of lungs into three classes namely: common pneumonia, coronavirus pneumonia and normal cases. In terms of accuracy, the proposed model is compared with recent pneumonia detection techniques. The results provided robust and consistent features to this system for pneumonia detection with predictive accuracy according to the three classes mentioned above for both imaging modalities: radiography at 99.81% and CT at 99.88%. This work implements an accurate computer-aided system for the analysis of radiographic and CT medical images. The results of the classification are promising and will certainly improve the diagnosis and decision making of lung diseases that keep appearing over time.
