Evaluation of alveolar clearance by Tc-99m DTPA radioaerosol inhalation scintigraphy in welders.
OBJECTIVES The welding process produces metal fumes and gases which may affect respiratory health. Technetium-99m diethylenetriaminepentaacetic acid (Tc-99m DTPA) dynamic lung scanning is an easy, noninvasive method to assess disorders of alveolar-capillary barrier permeability secondary to epithelial damage. We aimed to investigate the alveolar clearance by Tc-99m DTPA radioaerosol inhalation ...
متن کاملDetection of alveolar epithelial injury by 99mTC-DTPA radioaerosol inhalation lung scan following blunt chest trauma.
DTPA clearance rate is a reliable index of alveolar epithelial permeability, and is a highly sensitive marker of pulmonary epithelial damage, even of mild degree. In this study, 99mTc-DTPA aerosol inhalation scintigraphy was used to assesss the pulmonary epithelial membrane permeability and to investigate the possible application of this permeability value as an indicator of early alveolar or i...
متن کاملApplication of 99mTc-DTPA Radiotracer in Persian Cat’s Renal Scintigraphy
Purpose: To evaluate the suitability of Tc-DTPA as a radiotracer in Persian cat's renal scintigraphy. Methods: twelve adult healthy Persian cats were selected. For scintigraphy, the animals were anesthetized and TC-DTPA was injected via the femoral vein as a bolus at a dose of 1.5 mCi. Immediately after intravenous injection of radiotracer, scintigraphic operation was conducted on the renal org...
متن کاملInhalation cortisone therapy in bronchial asthma.
In its original concept, the term “allergy” was used to denote the changed state of the organism that followed the parenteral introduction of an antigen. Although the role of the adrenal corticoids in relation to this altered tissue state is not clear, it appears that in some way they interfere with tissue production of substances which are detrimental to cellular integrity, and thus permit a r...
متن کاملUnilateral renal agenesis revealed by hydronephrosis of contralateral kidney and explored by 99mTc-DMSA and 99mTc-DTPA scintigraphy
Renal scintigraphy is a physio-functional exploration permitting the exploration and assertion of unilateral renal agenesis. We report the case of a patient followed for a right hydronephrosis having revealed an agenesis of the contralateral kidney confirmed by 99mTc-DMSA scintigraphy. Also 99mTc-DTPA scintigraphy allowed the evaluation of the permeability of the urinary tract of the single rig...
