Technegas

12/01/2021 - "Technegas is the gold standard for the ventilation portion of SPECT-based ventilation-perfusion studies in pulmonary embolism and several respiratory pathologies. "
02/01/1992 - "Twenty patients, comprising nine children and eleven adults, were studied for various indications including assessment of pulmonary parenchymal disease, suspected pulmonary embolism and the lung clearance of modified Technegas. "
01/01/2020 - "This study was designed to evaluate the accuracy of detecting pulmonary embolism (PE) using the Technegas SPECT/CT combined with 68Ga PET/CT in a rabbit model. "
03/01/2023 - "V/Q SPECT and SPECT/CT offer significant advantages over planar V/Q, with or without the advantages of Technegas ventilation, and if available should be the preferred option in the evaluation of patients with suspected pulmonary embolism."
09/01/2009 - "A Tc-99m Technegas MAA-SPECT was performed on an 81-year-old woman to exclude pulmonary embolism. "

11/01/2001 - "Regional expiratory flow limitation studied with Technegas in asthma."
01/01/2019 - "Recent studies using Technegas ventilation SPECT have shown spatial imaging markers also relate to airway hyperresponsiveness in asthma, and are predicted by a MBNW index of peripheral ventilation heterogeneity. "
03/30/2023 - "Technegas has been used for diagnosis in over 4.4 m patients across 60 countries and now offers exciting opportunities in areas outside of PE, including asthma and chronic obstructive pulmonary disease (COPD). "
08/01/1999 - "Significant abnormalities were detected by ventilation scintigraphy with Technegas in patients with corticosteroid-dependent bronchial asthma even during remission. "
08/01/1999 - "With this background, the purpose of the present study was to assess patients with corticosteroid-dependent asthma by Tc-99m Technegas scintigraphy (Technegas) in both planar and SPECT images. "

06/01/1995 - "Further study of the clearance of the pertechnegas in pulmonary diseases is required to assess clinical usefulness."
02/01/2004 - "Using a triple-headed SPET unit and a physiological synchroniser, gated perfusion SPET was performed in a total of 78 patients with different pulmonary diseases, including metastatic nodules (n = 15); in 34 of these patients, it was performed in combination with gated technetium-99m Technegas SPET. "
01/01/1991 - "Four normal subjects and 31 patients with various lung diseases were studied by imaging the lungs following inhalation of technegas. "
07/01/1990 - "In patients with pulmonary disease, distribution of 99mTc-technegas was similar to that of 81mKr gas, although defect on 99mTc-technegas image was larger in severe obstructive disease. "

01/01/2002 - "It was found that the time to half clearance of pertechnegas of the lung is significantly decreased in idiopathic interstitial pneumonia (p<0.0001), hypersensitivity pneumonitis (p=0.0005) and connective tissue disease (p=0.002) but not in sarcoidosis when compared with 10 nonsmoking controls. "
01/01/2002 - "These results indicate that pertechnegas clearance is increased in idiopathic interstitial pneumonia, hypersensitivity pneumonitis and connective tissue disease, but not in sarcoidosis and is related to the functional severity of the disease."
01/01/2002 - "The clearance by pertechnegas in the four most common forms of ILD (eight patients with connective tissue disease, 10 with hypersensitivity pneumonitis, nine with idiopathic interstitial pneumonia and 10 with sarcoidosis) was measured and compared with 10 nonactive smoking controls. "
11/01/1990 - "Technegas generator using 99mTc-pertechnetate was tested on 4 normal subjects and 31 patients with various chest diseases including bronchogenic carcinoma, pneumonia, pulmonary tuberculosis, sarcoidosis, and so on. "

01/01/2002 - "It was found that the time to half clearance of pertechnegas of the lung is significantly decreased in idiopathic interstitial pneumonia (p<0.0001), hypersensitivity pneumonitis (p=0.0005) and connective tissue disease (p=0.002) but not in sarcoidosis when compared with 10 nonsmoking controls. "
01/01/2002 - "These results indicate that pertechnegas clearance is increased in idiopathic interstitial pneumonia, hypersensitivity pneumonitis and connective tissue disease, but not in sarcoidosis and is related to the functional severity of the disease."
01/01/2002 - "The clearance by pertechnegas in the four most common forms of ILD (eight patients with connective tissue disease, 10 with hypersensitivity pneumonitis, nine with idiopathic interstitial pneumonia and 10 with sarcoidosis) was measured and compared with 10 nonactive smoking controls. "
