ABSTRACT
Objective To investigate the value of gastrointestinal tract preparation with oral racean?isodamine tablets and isotonic mannitol in 18 F?FDG PET/CT imaging. Methods From July to September 2013, 129 patients with confirmed or suspected tumors who were referred for 18 F?FDG PET/CT imaging were divided into 2 groups. In the study group (30 males, 37 females, age (53.4±13.9) years), raceanisodam?ine tablets (10 mg) and 1 000-1 200 ml isotonic mannitol solution (2.5%) were orally taken at 10 min after in?jection of 18F?FDG;while in the control group (37 males, 25 females, age (60.0±12.8) years), 1 000-1 200 ml water was given. Mann?Whitney u test was used to compare the difference between the 2 groups in the filling degree of gastrointestinal lumen, delineation of tube wall, physiological uptake, matching degree of PET and CT images, delineation of mesentery, and the influence of gastrointestinal uptake on the identification of ab?dominal and pelvic lesions. χ2 test was used to compare the difference between the 2 groups in the uptake pattern of gastrointestinal tract and the incidence of side effects. Spearman correlation analysis was used to study the correlation between gastrointestinal lumen filling and PET/CT image matching. Results The gas?trointestinal lumen filling, delineation of tube wall, PET/CT image matching in the stomach, small intestine and colon (z: -5.096 to -2.665, all P0.05). There was statistically significant difference in the uptake pattern of small intestine between the two groups(χ2=12.884, P0.05). The incidence of transient diarrhea (20?9%, 14/67) was higher in the study group than that in the control group (4.8%, 3/62;χ2=7.256,P<0.01). Conclusions The abdominal PET/CT image quality is improved by gastrointestinal preparation with oral raceanisodamine tablets (10 mg) and 1 000-1 200 ml isoton?ic mannitol solution (2.5%).
ABSTRACT
Angel's trumpet is a poisonous shrub recently imported to Korea for ornamental PURPOSE. It contains tropane alkaloids and the ingestion of any part of the plant can cause serious anticholinergic toxicity. Not only accidental ingestion, intentional intake as hallucinogen is not uncommon in the United States and Europe. We report a woman who ingested angel's trumpet by mistake and showed anticholinergic syndrome. The potential public medical harm of this widespread plant should be reported in the media, along with the associated dangers from misuse as a hallucinogen.
