OBJECTIVE To evaluate whether respiratory therapy followed by the use of inhaled albuterol modifies the pulmonary deposition of inhaled tobramycin in patients with cystic fibrosis (CF) and whether pulmonary deposition correlates with disease severity or genotype. METHODS A prospective study was carried out including patients with CF older than 6 years of age and colonized with Pseudomonas aer...
99mTc-Macroaggregated Albumin (99mTc-MAA) has been used as a perfusion agent. This study described development of the 68Ga-MAA via commercially available kits from Pars-Isotopes Company as a 99mTc-MAA kit. 68Ge/68Ga generator was eluted with suprapure HCl (0.6 M, 6 mL) in 0.5 mL fractions. The two fractions with the highest 68GaCl3 activity were generally used for labeling purposes. After label...
UNLABELLED Planar lung scintigraphy is a standard method used for the diagnosis of lung embolism, but it is hampered by the high incidence of nondiagnostic tests. Ventilation/perfusion SPECT may possibly improve this situation. The objective of this study was to compare planar lung scintigraphy with ventilation/perfusion SPECT using pigs with artificially engendered lung emboli labeled with (20...
UNLABELLED The purpose of this study was to detect disturbances in pulmonary circulation in collagen disease patients by means of a non-invasive technique. METHODS Ventilation/perfusion scans with 133Xe gas and 99mTc-macroaggregated albumin (MAA) were performed in 109 patients with various collagen diseases. Functional images of V, Vol, Q and V/Q ratio were obtained at total lung capacity. Wa...
Relation between pulmonary arterial pressure and pleural pressure during the acute asthmatic attack.
CHEST, VOL. 63, NO. 4, APRIL 1973 SUPPLEMENT theophylline and occasionally on steroids. Dr. Coffey: Dr. Gee, do you find any changes in ATPase activity in relation to cytochalasin? Dr. Gee: Yes. ATPase activity is present in macrophages but cytochalasin B did not affect this. Dr. Coffey: I would think that more experiments are needed in this area; an effect on ATPase is still a possibility. Dr....
Changes in myocardial perfusion and left ventricular function were evaluated pre- and post-operatively (3--6 months) in 14 patients with unstable angina who underwent coronary artery bypass surgery. Perfusion was studied with intracoronary and intragraft injections of radiolabeled macroaggregated albumin particles. Of 20 abnormal perfusion areas identified preoperatively, 13 demonstrated improv...
Background: The standard treatment for locally advanced non-small cell lung cancer (LA-NSCLC) is represented by concomitant chemo-radiotherapy followed consolidation with durvalumab that ensures a 5-year survival of 46%. However, the risk radiotherapy-induced pneumonia (RIP) almost 10–15%. Complete cardiological examination also usually performed during cardiopulmonary pre-treatment evaluation ...
