Information Technology Journal , 2006,
Abstract: Chest radiograph inherently display wide dynamic range of X ray intensities. A wide variety of preprocessing procedures for chest radiograph based on local equalization, sharpening, fuzzy set, neural network and combination of modification of these techniques have been proposed. In this paper we have made analysis of twelve different techniques specifically derived and tested for enhancement of chest X ray giving brief details of working of algorithm. Radiology department are staring use central system to store digital chest radiograph. This provides opportunity to use chest workstation with different enhancement algorithm that run in background and radiologist may view a patient radiograph using different enhancement algorithm for subsequent analysis. Enhancement algorithm should be selected based on radiologist requirement and disease specific. Hence it is necessary to make review and analysis of available chest radiograph enhancement technique.
Finding on a chest radiograph: A dangerous complication of subclavian vein cannulation
Srinivasan Nataraj,Kumar Akshay
Indian Journal of Critical Care Medicine , 2010,
Abstract: Cannulation of the subclavian vein has its inherent risks. Post procedure chest radiograph is one of the investigations done to rule out immediate complications. Unless the clinician is aware as to what to look for in the radiograph, some of the dangerous complications can be overlooked. Accidental subclavian artery cannulation is identified immediately by color and jet of the blood. Also the position of the catheter tip has to be confirmed by obtaining the arterial pressure tracing using a pressure transducer. Non availability of Doppler ultrasound and pressure transducer are limiting factors for immediate confirmation of proper catheter placement. Also, in patients with severe hypotension and reduced oxygen content of blood, accidental arterial puncture may not show the characteristic bright red pulsatile back flow of arterial blood. In these situations radiography can be used as a diagnostic tool to rule out subclavian artery cannulation.
Can the Physicians or Surgions Do without Chest Radiograph?

Iranian Journal of Radiology , 2009,
Abstract: "nThe question is how much information is there in chest radiographs ? "nWe can consider the approximate heart size. Rough quantification of heart failure, very basic anatomy of the heart. The chest radiograph is widely available, cheap and very low long term risk of radiation. Chest radiographs are required in the initial consultation of heart or lung diseases. Follow-up radiographs are only required in certain situations. Chest radiographs contain significant information. But nowadays we look less critically, because it is easy to order echo, CT or MRI. Examples of frequently encountered abnormalities seen in our daily practice: "n-Change in hilar size or adenopathy "n-Alteration in hilar contour "n-Bronchial wall thickening "n-Obscuration of normal hilar structures "n

Indian Journal of Critical Care Medicine , 2005,
Abstract: Mechanical ventilation is a life-saving therapy used in children in PICU. These critically ill children are usually extensively investigated in PICU. Chest radiograph is an irreplaceable investigation in these patients prior to ventilation. AIM: We studied the impact of initial chest radiograph on the final outcome of ventilated children. DESIGN: Retrospective. SETTING: Tertiary care teaching hospital. METHOD: One hundred and forty-one children were included in the study. Initial chest radiograph of all the ventilated children was evaluated and outcome of these children was correlated with the initial radiograph at admission. RESULTS: Abnormal initial radiograph was recorded in 60% (n = 84) ventilated children. Overall mortality in ventilated children was 24% (n = 34). Ventilated children with abnormal initial radiograph had significantly greater mortality (28/84) than those with initial normal chest radiograph (6/57) (P < 0.05). CONCLUSION: Initial chest radiograph at the beginning of ventilation may be useful to predict the outcome of these children
Parapneumonic empyema diagnosed by chest radiograph and computed tomography
Ning Jin,John Paul Brady,David M. Widlus
Journal of Community Hospital Internal Medicine Perspectives , 2013, DOI: 10.3402/jchimp.v3i1.20503
Abstract: Pleural effusion is commonly seen associated with pneumonia. When this progresses to empyema, directed therapy is frequently required. Chest radiographic and computed tomography findings can help distinguish empyema from a transudative pleural effusion.
Comparing chest Radiograph and Tuberculin Skin Tests in Children

Acta Medica Iranica , 2009,
Abstract: World Health organization (WHO) has reported that out of more than 10,000 of 250,000 tuberculosis afflicted children die annually. Pulmonary tuberculosis is a research priority in our country, and diagnos-ing this disease especially in children who are known as the major transmitter of the disease is rather difficult. As a result, it was decided to conduct an overall assessment on this age group in order to determine the importance of the findings of chest radiography and skin test in diagnosing the disease. The present descriptive study was carried out based on the findings of a health plan in Fasa , a Iranian town, during 1995 and 1996, on 2 groups: first-grade students of Fasa elementary schools. Among 2263 students, 102 (4.5%) cases had a positive skin test. According to the radiographic findings, tuberculosis was reported in seven (6.9%) of them. The diagnosis of tuberculosis is more difficult in children; this is because taking sputum samples for laboratory examination is rather difficult especially in children lower than 10 years. In this group, diagnosis is made based on the symptoms like cough, weight loss, history of contact with a TB patient and other diagnostic procedures including chest radiographies and skin test.

Brazilian Journal of Infectious Diseases , 2001, DOI: 10.1590/S1413-86702001000200005
Abstract: this study was designed to estimate the prevalence of pulmonary radiograph abnormalities and describe the distribution of the patterns of radiographic alterations among patients hospitalized with leptospirosis. chest radiographs of 139 patients hospitalized with leptospirosis in couto maia hospital, in salvador, bahia, brazil, between july, 1997, and july, 1999, were analyzed. the radiographs were requested soon after hospital admission, independent of the clinical manifestations of the patients. only the first radiograph was considered. pulmonary radiograph alterations were recorded in 35/139 patients (25.2%); 95% mid-point confidence interval = 18.5% to 32.9%. among the patients with radiograph alterations, alveolar infiltrate was seen in 26/35 (74.3%). the lesions were bilateral in 54.3% and located in the inferior lobes in 45.5%. pleural effusion, represented by blunting of the costo-phrenic angle, was detected in 8.6% of the patients. the pattern of the pulmonary alterations, predominantly bilateral alveolar infiltrates, is consistent with the evidence that the basic pulmonary alteration in leptospirosis is a generalized capillaritis.

Abstract: The concept of occult pneumothorax is well accepted among the surgical trauma literature [1-5]. In trauma patients, because of restrictions regarding cervical spine immobilization, AP chest radiograph is usually utilized to detect intrathoracic pathology. This report emphasizes how AP chest radiograph can dangerously delay the recognition of a pneumothorax. More advanced imaging modalities including Chest CT scan or ultrasonography is therefore manadatory to exclude the diagnosis.A 24-year-old male presented to the ER after a motor vehicle accident. On admission the patient was confused with a Glasgow coma score of 14/15. CT brain revealed brain edema and fracture skull base. Chest exam and arterial blood gases were satisfactory. AP chest X-ray revealed no evidence of pneumothorax as demonstrated in Figure 1 panel A, adapted from Omar et. al. [6] CT chest performed immediately after the X-ray revealed a right sided pneumothorax (Figure 1 panel B), adapted from Omar et. al [6]This case represents an example of a true occult pneumothorax where an AP chest X-ray failed to show an existing pneumothorax. This emphasizes the importance of chest CT in any trauma victim who is tachypnic or hypoxic when the initial AP chest radiograph appears normal. This is especially important in patients expected to be maintained on positive pressure ventilation.A 29-year-old restrained driver was involved in a T-bone vehicular accident. At the scene of the accident the patient's Glasgow coma score was 4/15. The patient was intubated for airway protection and sent to the ER. While in the ER, an AP chest X-ray was completed (Figure 2 panel a), adapted from Omar et. al, [6] which revealed a mechanically ventilated patient with diffuse airspace opacities prominently located in the left lower lung field. In the setting of trauma, this was interpreted as lung contusions.The patient was immediately sent for a chest CT scan (Figure 2 panel b), adapted from Omar et. al, [6] that was performed 15
