N/A Gastrointestinal endoscopy is one of the most frequent procedures, but relatively little is known about its pulmonary effects. Pulse oximeter is a convenient and non-invasive methods which monitors SaO2 and pluse rate. So, we studied the change of SaO2 and pluse rates during esophagogas-troduodenoscopy in the patients with impaired plumonary function and normal controls by pluse oximeter. In conclusion, the drop in SaO2 during endoscopy could occur in the pulmonary disease patients with mild to moderate imparied pulmonary function, but this change was transient and recovered rapidly during examination. So, we suppese that specific therapy such as O2 supply may not be requried durging endoscopy in these patients.

N/A The value of 99mTc-RBC scintigraphy and SPECT in the diagnosis of hepatic hemangioma was evaluated in 27 patients with 38 hemangiomas and 13 patients with 15 nonhemangiomas. Twenty four (63.2%) of 38 hemangiomas were detected by planar delayed RBC imaging, whereas 30 (78.9%) hemangiomas were detected by the delayed RBC SPECT. Increase in sensitivity was noted in nodules less than 2 cm in diameter. The smallest hemangioma shown by delayed RBC SPECT was 0.9 cm in diameter. All of nonhemangiomatous lesions show normal or decreased activity in delayed blood pool images. We concluded that 99mTc-RBC SPECT is an accurate method for the detection of hepatic hemangioma and is more sensitive than planar imaging in depicting small lesions.
