Spurious lung perfusion ventilation defect on planar ventilation-perfusion scan detected by SPECT imaging
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...
متن کاملVentilation studies and the perfusion lung scan.
hypothyroidism is increased dietary iodine is certainly weakened by the observation that radioresistance was not found in carbimazoleor perchlorate-treated patients. As we stated in the article and as Dr. Wiener has emphasized, the only evidence for iodine as a cause of increased hypothyroidism depends on phar macologie doses. In a manner similar to this last statement, the only obvious differe...
متن کاملDiagnosis of thromboembolic disease: Combined ventilation perfusion lung scan and compression ultrasonography
The clinical management of pulmonary embolism and deep venous thrombosis of the legs are similar and requires prolonged anticoagulation therapy. The standard diagnostic approach in patients suspected of pulmonary embolism is ventilation-perfusion (V/Q) lung scan and compression ultrasonography to detect deep venous thrombosis. This retrospective study analyzed the role of V/Q lung scan an...
متن کاملVentilation/perfusion lung scan in pulmonary veno-occlusive disease.
Pulmonary veno-occlusive disease (PVOD), a rare form of pulmonary arterial hypertension (PAH), requires histological proof for definitive diagnosis; however, lung biopsy is not recommended in PAH. Recent conjoint European Respiratory Society/European Society of Cardiology guidelines suggest that nonmatched perfusion defects on ventilation/perfusion (V'/Q') lung scanning in PAH patients may sugg...
متن کاملEvaluation of the Influence of Exposure Index on Image Quality and Radiation Dose
Introduction: The introduction of digital radiography has led to a significant problem in terms of dose creep. To address this problem, manufacturers have established a set of exposure indicators (EI) as a feedback mechanism to safeguard against overexposure. The EI is the measure of incident exposure to the detector that is directly proportional to the signal-to-noise...
