Despite recognized limitations, structural imaging with CT remains the standard technique for evaluating the response of lung cancer to both chemotherapy and radiotherapy. This evaluation has become increasingly important with the advent of neoadjuvant therapy before surgery. The high uptake of (18)F-FDG in most lung cancers and the demonstration that successful treatment reduces uptake have le...
Most inhaled beta(2)-adrenergic agonist and anticholinergic bronchodilators have low lipid solubility because of their transient or permanent positive net charge at physiologic pH. Airway absorption of these cationic drugs is incompletely understood. We examined carrier-mediated mechanisms of cationic drug uptake by human airway epithelia. Airway tissues and epithelial cells, obtained from lung...
increased metabolic activity in muscle secondary to excessive muscle activity during the uptake phase and shortly before fdg injection is a known phenomenon. we present fdg pet/ct findings in a young male, known case of carcinoma maxilla his scan showed diffuse increased metabolic activity in multiple skeletal muscle groups. there was history of unaccustomed, strenuous sports activity of skiing...
