Mismatch between gallium-67 uptake and CT findings in a case of pulmonary alveolar proteinosis.

چکیده
Gallium-67 citrate (67Ga) scintigraphy has been used as an indicator of activity of diffuse interstitial lung diseases. However, little has been mentioned in pulmonary alveolar proteinosis (PAP). Here we present a 53-year-old man with PAP showing patchy 67Ga uptake by single photon emission computed tomography (SPECT). Interestingly, the strong 67Ga uptake was observed in areas where ground-glass opacities were faint on chest CT. The uptake persisted after whole-lung lavage while the ground-glass opacity improved markedly. Although the precise mechanism of 67Ga uptake remains unclear, 67Ga SPECT findings may reflect the different pathological condition of PAP than that shown by CT.

متن کاملPreparation and biodistribution study of 67Ga-gallium calcitonin
Introduction: In order to develop a radiolabeled calcitonin (CT) derivative for receptor imaging studies, CT was successively labeled with 67Ga-gallium chloride. Methods: The best results of the conjugation were obtained by the addition of 0.5 ml of a CT nasal pharmaceutical solution (1100 IU) to a glass tube pre-coated with DTPA-dianhydride (0.01 mg) at 25°C with continuous mild st...

Pulmonary alveolar proteinosis (PAP) is a rare disease in which surfactant accumulates abnormally in the pulmonary alveolar walls and causes respiratory symptoms. The only known effective treatment for PAP is pulmonary lavage. We have reported an 11year-old girl with pulmonary alveolar proteinosis who underwent pulmonary lavage with normal saline under general anesthesia by a new method (using ...

s:696:"Pulmonary alveolar microlithiasis (PAM) is classified as an elective dysmetabolic thesaurotic pneumoalveolitis and characterized by the presence within the alveoli of the lungs of myriad of tiny calculi. The classic presentation of the chest radiography is unmistakable with multiple small "sand-like" opacities diffusely involving both lung fields. We present a case of male infertility fo...
