| The aim of this study was to evaluate the alveolus-capillary permeability by the lung clearance rate of 99mTc-DTPA(Technetium99m-diethylene triamine penta-acetate), (LCR-DTPA), both in normal and in asymptomatic HIV seroreactive patients. Thirty individuals were studied, 21 seronegative normal volunteers and 9 HIV seroreactive patients presenting normal chest radiography and no respiratory infection symptoms. LCR-DTPA was determined by inhaling 99mTc-DTPA and obtaining images in a gamma camera. The 99mTc-DTPA clearance rate in normal individuals was 0.99±0.15%.min-1 and in patients 2.31±1.25%.min-1. There was a significant statistical difference between the two groups (p< 0.05). Two patients who presented LCR-DTPA higher than 4.3 %.min-1 presented... |

| Clinical images are worthwhile in Health Sciences and their analysis and correct interpretation aid the professionals,such as physicians, physiotherapists and occupational therapists, to make decisions and take subsequent therapeutic and/or rehabilitation measures. Other factors, besides the state of the disease, may interfere and affect the bioavailability of the radiopharmaceuticals (radiobiocomplexes) and the quality of the SPECT and PET images. Furthermore, the labeling of some of these radiobiocomplexes, such as plasma proteins, white blood cells and red blood cells, with 99mT, can also be modified. These factors include drugs (synthetic and natural) and dietary conditions, as well as some medical procedures (invasive or non-invasive), such as... |
