Detection of malignant lung nodules in chest radiographs is currently performed by pulmonary radiologists, potentially with the aid of CAD systems. Recent advancements in convolutional neural network (CNN) models have improved image classification and detection for many tasks, but there has been little exploration of their use for nodule detection in chest radiographs. In this paper we explore ...

prevalence of thyroid nodules diagnosed by ultrasonography has been reported to be high (about 50%) probably due to iodine deficiency in our region. most thyroid nodules benign but some require treatment for cosmetic reasons or subjective symptoms. the conventional method of treatment in iran is surgery. for the first time in iran, from february 2016, 50 patients with 63 nodules (solid or cysti...

background:speech is the most important communication tool and is the smooth product of four systems: respiratory, phonatory, resonatory, and articulatory. currently, a variety of voice disorder occurred because of life style and environmental pollutants. vocal nodule is one of the most prevalent disorders in this category. considering the point that the air required for vocal cords vibration i...

Determining the change in the pulmonary nodule size is a critical measurement for cancer diagnosis and therapy evaluation. In this study, an image-processing method that quantifies the nodule volume change based on computed tomography (CT) images is proposed. The proposed method consists of the following four steps: CT image interpolation, pulmonary region segmentation, nodule extraction, and n...

Appearance of a thyroid nodule has become a daily occurrence in clinical practice. Adequate thyroid nodule assessment requires several diagnostic tests and multiple medical appointments, which results in a substantial delay in diagnosis. Implementation of a high-resolution thyroid nodule clinic largely avoids these drawbacks by condensing in a single appointment all tests required for adequate ...

BACKGROUND In lung cancer screening, a nodule management protocol describes nodule assessment and thresholds for nodule size and growth rate to identify patients who require immediate diagnostic evaluation or additional imaging exams. The Netherlands-Leuvens Screening Trial and the National Lung Screening Trial used different selection criteria and nodule management protocols. Several modelling...

a 63-year-old woman presented with a history of hyperthyroidism symptoms over two years, referred for thyroid scintigraphy. in the hospital archives we have met her previous thyroid scintigraphy showing a hot nodule in the upper part of right thyroid lobe. however, her recent thyroid scintigraphy was showing only cold nodules but no hot nodule, giving an impression that she had some treatment t...
