Does sPECT improve accuracy of somatostatin receptor scintigraphy in abdominal carcinoid tumors?
Indium-111-pentetreotide scintigraphy is a safe and practical procedure. SPECT appears to be more sensitive than planar scintigraphy and conventional methods to detect abdominal carcinoids; it can increase the number of visualized tumor sites and that of patients with positive findings and may therefore have a role not only in the mapping of tumor spread but also in therapeutic decisions.
The current findings support the hypothesis that cigarette smoking is an important independent risk factor for the development of new asthma cases in adults with allergic rhinitis.
