The purpose of this study was to reduce the radiation dosage associated with computed tomography (CT) lung cancer screening while maintaining overall diagnostic image quality and definition of ground-glass opacities (GGOs). A lung screening phantom and a multipurpose chest phantom were used to quantitatively assess the performance of two iterative image reconstruction algorithms (adaptive stati...

Chest tube is a flexible plastic tube used to discharge secretion in the cavity between the lungs and chest named pleural cavity. Normally, there is a small amount of fluid in the cavity between the lungs and chest; This fluid helps the movement of lungs during breathing without abrasion. Entrance of bit of air, blood or pus because injury in the pleural cavity can prevent the lungs from fully ...

Approximately 1.5 million patients are diagnosed with pleural effusion each year in the United States. Clinical manifestations of pleural effusion include dyspnea, pleuritic chest pain, cough, fever, fever, chills and weight loss and depending on the underlying disease. Diagnostic tools include chest radiograph, ultrasound, and computed tomography {CT).Ultrasound guided pigtail catheters as the...

Automatic tube current modulation (TCM) is used in modern CT devices. This is implemented in the numerical calculation of dose conversion coefficients for CT examinations. For four models of adults, the female and male reference models of ICRP and ICRU and a lighter and a heavier female model, dose conversion coefficients normalized to CTDI(vol) (DCC(CT)) have been computed with a Monte Carlo t...

INTRODUCTION The management of pediatric empyema remains controversial. We contend that early thoracoscopic intervention results in shorter hospital stays, decreased morbidity, and superior outcomes. We propose an algorithm using early image-guided thoracoscopy as an effective treatment for pediatric empyema. METHODS Consecutive pediatric empyemas treated from November 1997 to April 2001 usin...

This 12-year-old girl was transferred from an outside hospital for treatment of pneumonia. She had been well until 7 days before admission, when she developed what was felt to be cellulitis of her left lower extremity. She was given intravenous clindamycin, and the swelling and erythema improved. However, the following day, she started having respiratory distress, and she was found to have an i...

A 77-year-old man presented with acute breathlessness. He had a history of smoking 20 cigarettes per day for 45 years, but stopped smoking at the age of 74. He had pneumothorax of the right three times, which was treated surgically two times. On arrival, he was clear and ambulatory. The vital signs were stable: blood pressure was 130/80 mmHg, pulse rate 84 beats per minute, respiratory rate 16 ...

Triple-rule-out (TRO) computed tomographic (CT) angiography can provide a cost-effective evaluation of the coronary arteries, aorta, pulmonary arteries, and adjacent intrathoracic structures for the patient with acute chest pain. TRO CT is most appropriate for the patient who is judged to be at low to intermediate risk for acute coronary syndrome (ACS) and whose symptoms may also be attributed ...

OBJECTIVE To determine the incidence, reasons and prognosis about Horner's syndrome in thoracic surgical patients. METHODS In this prospective clinical study, 933 adult patients were assessed between the years of 1998 and 2002. All patients who underwent chest tube insertion (n: 662 patients) or thoracotomy (n: 342 patients), or who had thoracic trauma (n: 268 patients) were routinely examine...
