This paper presents a system for medical image diagnosis that uses transfer learning (TL) and feature selection techniques. The main aim of TL on pre-trained models such as MobileNetV3 is to extract features from raw images. Here, novel optimization algorithm called the Artificial Hummingbird Algorithm based Aquila Optimization (AHA-AO) proposed. AHA-AO used select only most relevant ensure imp...

Our natural language understanding system outputs a list of diseases, findings, and appliances found in a chest x-ray report. The system described in this paper links those diseases and findings that are causally related. Using Bayesian networks to model the conceptual and diagnostic information found in a chest xray we are able to infer more specific information about thefindings that are link...

Picture 1. Comparison of chest x-ray and three-dimensional images. A) Posteroanterior chest xray film on admission showed a large mass occupying the right lower-lung field (arrow) with a right-sided aortic arch (arrowhead). B) Three-dimensional image by MDCT clearly showed aneurysms of the right-sided descending thoracic aorta (arrow) with a right-sided aortic arch (arrowhead) and abdominal aor...

This paper presents a computer aided detection scheme on digital chest radiographs for pneumoconiosis screening. The scheme involves several medical image processing and analysis technologies, i.e. lung segmentation algorithm using the active shape model, image enhancement and features extraction from lung regions, feature down-selection by correlation analysis and clustering method, classifica...

On examination, the epigastrium was tender but no mass was palpable. Investigations for his epigastric pain showed normal levels of serum amylase, normal electrocardiograph, normal erect abdominal and chest Xray. Further tests done included abdominal ultrasound that showed hyperechoic lesion in the gallbladder, suggestive of a polyp. The liver, spleen and pancreas were reported as normal. OGDS ...

An 88yearold woman with rheumatoid arthritis (RA) was transferred to our hospital due to cough, fever, and hypoxia. She had received 8 mg of weekly methotrexate and 4 mg of daily prednisolone and had not been given Pneumocystis jirovecii pneumonia (PCP) prophylaxis. Her chest Xray showed consolidation of the left lower lung field (Figure 1), and chest computed tomography confirmed left lower lo...

A 40-year-old female dental technician visited our hospital for the investigation of a chest X-ray abnormality. Chest computed tomography demonstrated centrilobular nodules and lung volume reduction, and her serum KL-6 level was elevated. A histological analysis of the specimens obtained on a surgical lung biopsy showed peribronchiolar fibrosis with pigmented macrophages and cholesterol clefts....
