Background: Sarcoidosis is an unknown etiology multisystem inflammatory disease in which noncaseating granulomas (a collections of inflammatory cells) form and grow in various organs, involving predominantly lungs, intrathoracic lymph node, skin and eyes. It most commonly affects patients between 20 and 40 years old of age but it could be observed at any age (female predominance; rare in Asians). Discussi Read More

Background: Sarcoidosis is a multisystem granulomatous disease with a neglected but high prevalence of life-threatening cardiac involvement. Discussion: The clinical presentation of Cardiac Sarcoidosis (CS) depends upon the location and extent of the granulomatous inflammation, with left ventricular free wall the most common location followed by interventricular septum. The lack of a diagnostic gold standard and the unpr Read More

Background: 18F-fluorodeoxyglucose positron emission tomography integrated with computed tomography (18-F-FDG-PET/CT) is getting wide consensus in the diagnosis and staging of neoplastic disorders and represents a useful tool in the assessment of various inflammatory conditions. Discussion: Sarcoidosis is an uncommon disease characterized by the systemic formation of noncaseating granulomas. Lungs are the sit Read More

Objective: To determine the prevalence of abdominal involvement, distribution pattern and evaluate role of hybrid molecular imaging in patients with abdominal sarcoidosis. Methods: Between January 2010 and December 2011, 98 patients with chronic sarcoidosis and presence of prolonged symptoms or other findings suggestive of active disease were referred to FDG PET/CT examination. Active disease was found in 82 patie Read More

Background: Sarcoidosis is a multisystem granulomatous disorder of unknown origin characterized by nonspecific clinical symptomatology. 18F-FDG PET/CT can visualize activated inflammatory cells of sarcoidosis and simultaneously provide whole-body images. Objective: To evaluate the clinical usefulness of 18F-FDG PET/CT and its semiquantitative parameters for the assessment of treatment efficacy in patients with sarcoidosis. Read More

Background: Temporal Lobe Epilepsy (TLE) comprises the most common form of symptomatic refractory focal epilepsy in adults. Accurate lateralization and localization of the epileptogenic focus are a significant prerequisite for determining surgical candidacy once the patient has been deemed medically intractable. Structural MR imaging, clinical, electrophysiological, and neurophysiological data have an established role Read More

Background: This paper reviews segmentation techniques for 2D ultrasound fetal images. Fetal anatomy measurements derived from the segmentation results are used to monitor the growth of the fetus. Discussion: The segmentation of fetal ultrasound images is a difficult task due to inherent artifacts and degradation of image quality with gestational age. There are segmentation techniques for particular biological str Read More

Objective: The aim of the research was to determine the dependence of the blood flow velocity in the thyroid arteries in patients with Autoimmune Thyroiditis (AIT) on the presence of atherosclerotic carotid disease and the level of systemic blood pressure. Methods: The research involved 20 patients with AIT in euthyroid state, 30 patients AIT in euthyroid state with stable Coronary Heart Disease (CHD), 30 patients with stable Read More

Background: Digital Signal Processing (D.S.P) is an evolutionary field. It has a vast variety of applications in all fields. Bio medical engineering has various applications of digital signal processing. Digital Image Processing is one of the branches of signal processing. Medical image modalities proved to be helpful for disease diagnosis. Higher expertise is required in image analysis by medical professional, either doctors or radio Read More

Background: Mediastinal bronchial artery aneurysms are uncommon, with fewer than 40 published case reports. This study objective was to evaluate the short term follow up of two cases ruptured Bronchial Artery Aneurysm (rBAA) treated with aneurysm embolization and subsequent aortic stent graft. Methods: Two cases of rBAA were treated with a combination of an aortic stent-graft and aneurysm embolization. Wit Read More

Background: Recurrent episodes of isolated pericardial effusion due to tuberculosis, leading to reduced Left Ventricle Ejection Fraction (LVEF), are uncommon. Methods: This is a case report of a previously healthy 32-years old male with tuberculous induced pericardial effusion as isolated manifestation. The only known exposure of tuberculosis was a brother with whom the patient did not have physical contact during the la Read More

Background: Lung lesions often appear in patients with sarcoidosis; however, miliary opacities are rare. We present the case of a 55-year-old Indian man who presented with dyspnea and low-grade fever. Discussion: Miliary Tuberculosis (TB) was initially suspected, despite the direct microscopic examination from bronchoalveolar lavage was negative for acid-fast bacilli because imaging showed miliary opacities, and transbronchi Read More
