A Computer Aided Diagnosis (CAD) system has a significant importance and key role in cancer detection especially from lungs by using medical imaging modalities. It is much helpful to the radiologists by providing a second opinion regarding diagnosis which improves their performance in terms of time and precision. This work examines the effectiveness of automatic cancer detection methods from lungs using Computed T Read More

The automatic detection of Ground-Glass Opacity (GGO) in lung CT images is very useful for early diagnosis of lung cancers. In this paper, we present a study of previous GGO detection methods and summarize a common algorithm framework, which includes three components: preprocessing, candidate extraction and GGO identification. For each component, we discuss the main methods. Also we further describ Read More

Acute appendicitis in the elderly represents an emerging problem. Although it has been considered for a long time an exclusive disease of the second and third decades of life, the increase of life expectancy has resulted in an increasing number of cases found in the elderly. While the key element for the diagnosis in the young is represented by typical history and symptoms, the diagnosis is more difficult in the elderly mostl Read More

Testicular malignancy is the most common nonhematologic malignancy in young men. Around 95% of them are germ cell tumors (GCTs), and with correct assessment of the disease and application of chemotherapy and radiotherapy survival rates of more than 90% can be achieved. Imaging studies not only aid in the diagnosis of testicular cancer but also help determine the tumor extent and site of metastatic disease, in moni Read More

The Cerenkov luminescence imaging (CLI) has built a bridge between the nuclear and optical imaging, and opened a new direction of optical imaging in clinic translation. However, the wide applications of CLI are limited by the weak intensity and poor penetration capacity. By coupling highly sensitive charged coupled device camera with optical fiber bundle based endoscope, Cerenkov luminescence endoscopy (CLE) ha Read More

Background: Edge preserving filters are widely preferred for medical image denoising as they do not degrade the morphological edges during smoothing. Even though, the operational parameters of these filters have crucial influence on their performance, the parameters are selected subjectively. The optimum values of the operational parameters can be selected objectively with the help of edge quality indices. The av Read More

To perform a systematic review of the diagnostic value of dual energy computed tomography angiography (DECTA) in peripheral arterial disease (PAD). PubMed, ProQuest, Medline and ScienceDirect were searched for studies evaluating DECTA compared to conventional computed tomography angiography (CTA) and digital subtraction angiography (DSA) in patients with PAD. Diagnostic value, image quality and radia Read More

Background: Generally, the texture information stored in the natural scene images provide some vital clues to the image based on the applications include Content Based Image Retrieval (CBIR), scene understanding, assistive navigation and automatic coding. Still locating the text from complex background and recognizing the characters with different colors are the major issues in image processing applications. Methods: To over Read More

Objective: Primary pulmonary cryptococcosis in immunocompetent patients is very easily misdiagnosed or even missed. Accurate diagnosis of this disease is critical for a timely and proper treatment. This study aims to address the importance of computed tomography (CT) and CT-guided percutaneous needle biopsy for primary pulmonary cryptococcosis in immunocompetent patients. Methods: We retrospectively analyze Read More

The diffuse lymphoma is a malignant tumor of lymphoid tissues. It is associated with abnormal, unlimited and uncontrolled proliferation of lymphoid cells. Until now, expert pathologists have identified diffuse lymphoma cells disease manually. This paper introduces automatic system with a friendly user interface to differentiate between the categories of the diffuse lymphoma cells. This research is based on the morphological featur Read More

Glaucoma is a disease in which damage of the optic nerve of eye leads to progressive and irreversible vision loss. It is caused due to enlargement of the optic cup present inside the optic disc. It can be detected by calculating the CDR value which is the ratio of segmented optic cup to the segmented optic disc. Optic disc is the point from where various ganglion cells exit from eye to form an optic nerve. On the other hand, Read More
