Pulmonary embolism (PE) is a preventable cause of morbidity and mortality which needs prompt recognition. Ventilation-perfusion (V/Q) scan is a well-established diagnostic test for evaluation of suspected PE. We report a 32-year-old woman with history of rheumatologic disease and acute dyspnea, who was referred for V/Q scintigraphy. The planar images revealed multiple mismatched defects through...

Ventilation/perfusion (V/Q) lung scintigraphy, when used for the clinical determination of the presence or absence of pulmonary embolism, has been much studied by medical imagers. Inherent to a ‘‘cold-spot’’ scan targeting the normal pulmonary tissue, the deck has always been stacked against us and our specialty frequently maligned by the referring physicians as practicing ‘‘unclear’’ and not n...

A 62-year-old man with a past medical history notable for hypertension, osteoarthritis, and calf deep vein thrombosis at age 55 following a total hip arthroplasty presents to the emergency department with acute-onset dyspnea and right-sided pleuritic chest pains. His medications consist of a calcium channel blocker and a COX-2 inhibitor. Pretest clinical suspicion for pulmonary embolism (PE) is...

a 21-year old man with cervical spinal cord damage due to diving was admitted in the icu. tracheostomy was performed due to prolonged mechanical ventilation. left lung atelectasis happened frequently. because of the difficulty of bronchoscopy and failing of recruitment, using a double lumen, two tracheal tubes were guided into the left and right lungs through the tracheostomy stoma site. after ...

conclusions: the effects of propofol on hemodynamics and arterial oxygen pressure during one- or two-lung ventilation were not different from those of isoflurane. results: sixty patients (mean age = 4124.18 ± 18.63 years) were divided into two groups. the age and gender of the subjects were not statistically different between the two groups. in the propofol group, the arterial oxygen pressure d...

No single non invasive test has sufficient diagnostic accuracy to be used alone for diagnosing or ruling out pulmonary embolism. Therefore, modern diagnostic strategies for pulmonary embolism rely on combinations of non invasive tests such as plasma D-dimer measurement, lower limb venous compression ultrasonography, ventilation-perfusion lung scan and/or spiral CT, the results of which should b...

AIM To evaluate the feasibility of V/Q SPECT and analyze its contribution to planar V/Q lung scintigraphy in the diagnosis of pulmonary embolism (PE). MATERIAL AND METHODS A total of 109 patients with suspected PE showing Wells score>2 and elevated D-dimer were studied. The V/Q could not be completed in 7 patients, so they were excluded. Ventilation and perfusion scans were done using Techneg...

The features of Hypertrophic pulmunary osteoarthropathy (HPOA) on radionuclide bone scintigraphy have been well described in case reports and small series of patients. The aim of this study was to investigate prospectively the prevalence and distribution of HPOA in a large series of patients with carcinoma of the lung. Two hundred and eleven patients aged 31-89 years (average age 66 years...
