“…The I/A count ratio was significantly higher in the soda water cohort (1.9 ± 0.51) compared with the control group (1.5 ± 0.35, p < 0.0001). In addition, three-dimensional computed tomography was performed in both groups and volumetric analysis of gastric distention was performed demonstrating a substantial increase in gastric volume from 55.9 to 276.6 ml with soda water administration [Hara et al 2008]. We present the largest patient population to date examining the use of soda water prior to both stress and resting Tc-99m SPECT imaging.…”

Background: Small, observational trials have suggested a reduction in adjacent gastric activity with ingestion of soda water in myocardial perfusion imaging (MPI). We report our findings prior to and after implementation of soda water in 467 consecutive MPI studies. Methods: Consecutive MPI studies performed at a high-volume facility referred for vasodilator (VD) or exercise treadmill testing (ETT) were retrospectively reviewed before and after implementation of the soda water protocol. Patients undergoing the soda water protocol received 100 ml of soda water administered 30 min prior to image acquisition and after stress. Studies were performed using a same day rest/stress protocol. Incidence of adjacent gastric activity, diaphragmatic attenuation, stress and rest perfusion defects, and major adverse cardiovascular events (MACE) outcomes defined as death, myocardial infarction, stroke, reevaluation for chest pain, and late revascularization (>90 days from MPI) were abstracted using International Classification of Diseases, Ninth Revision (ICD-9) search. Results: Two hundred and eighteen studies were performed prior to implementation of the soda water protocol and 249 studies were performed with the use of soda water. Baseline demographic data were equal between the groups with the exception of more patients undergoing VD stress receiving soda water (p < 0.001). Soda water was not associated with a decreased incidence of adjacent gastric activity with stress (54.7% versus 61.9% with no soda water, p = 0.129) or rest (68.6% versus 69.5% with no soda water, p = 0.919) imaging. Less adjacent gastric activity was observed with patients undergoing ETT who received soda water (42.5% versus 56.9% with no soda water, p = 0.031), but no difference was observed between the groups with VD stress (69.0% versus 68.1% with no soda water, p = 1.000). Conclusion: The use of soda water prior to technetium-99m MPI was associated with lower rates of adjacent gastric activity only in patients undergoing ETT stress but not rest or VD stress. This differs from previously published data.

“…Hara et al [5] showed another approach to increase stomach volume using carbon dioxide gas in patients undergoing pharmacological stress (adenosine). In the present randomized study, we compared the effects of carbonated water, which releases carbon dioxide gas, with those of still water in patients scheduled to undergo exercise myocardial SPECT, adenosine myocardial SPECT and rest myocardial SPECT.…”

Objective In myocardial perfusion single-photon emission computed tomography (SPECT), abdominal activity often interferes with the evaluation of perfusion in the inferior wall, especially after pharmacological stress. In this randomized study, we examined the effect of carbonated water intake versus still water intake on the quality of images obtained during myocardial perfusion images (MPI) studies. Methods A total of 467 MIBI studies were randomized into a carbonated water group and a water group. The presence of intestinal activity adjacent to the inferior wall was evaluated by two observers. Furthermore, a semiquantitative analysis was performed in the adenosine subgroup, using a count ratio of the inferior myocardial wall and adjacent abdominal activity. Results The need for repeated SPECT in the adenosine studies was 5.3 % in the carbonated water group versus 19.4 % in the still water group (p = 0.019). The inferior wall-to-abdomen count ratio was significantly higher in the carbonated water group compared to the still water group (2.11 ± 1.00 vs. 1.72 ± 0.73, p \ 0.001). The effect of carbonated water during rest and after exercise was not significant. Conclusions This randomized study showed that carbonated water significantly reduced the interference of extra-cardiac activity in adenosine SPECT MPI.

“…Attenuation artifacts are a problem in the accurate evaluation of myocardial perfusion scintigraphy. The left anterior-lateral attenuation artifact depending on breast tissue in female and inferior walls attenuation artifact due to diaphragm in men can lead to false positive evaluation on myocardial perfusion SPECT [4][5][6][7][8][9][10][11][12][13][14][15].…”
