QUANTITATIVE GASTRIC EMPTYING STUDY

DATE: 2/2/2006

PROCEDURE:  Following oral administration of radiolabeled food, labeled with technetium 99m sulfur colloid, projection images of the abdomen were obtained at 15-minute intervals out to 60 minutes.  When possible both anterior and posterior projection images were obtained to allow the calculation of the geometric mean activity.

RADIOPHARMACEUTICAL DOSE Tc 99m sulfur colloid: [1] mCi

MEAL: [...] cc Formula via NG tube

COMPARISON:  None.

CLINICAL HISTORY: The patient is a [...]-old [fe]male with a history of [...], now referred to Nuclear Medicine to evaluate for gastric emptying.

FINDINGS: [...]% of tracer was cleared at 90 minutes. T ½ was [...] minutes.  No tracer activity in the distal esophagus was observed. 

CONCLUSIONS:  

Normal study showing no delay in gastric emptying.  There was no evidence of reflux into the esophagus during the acquisition period.

This is a likely normal gastric emptying study. 

This is likely an abnormal gastric emptying study with evidence of delayed gastric emptying.

Please note, that there are no normal values established for ages below 3 years (in adults 50% or more gastric emptying of a solid meal at 90 minutes is considered normal).

ADULT NORMAL: Less than 63% remaining (or greater than 37% emptying) at 60 minutes.

ADULT NORMAL: Less than 50% remaining (or greater than 50% emptying) at 90 minutes

Thank you for referring this patient to the UCLA Nuclear Medicine Clinic.

I, [...], M.D., Ph.D., have reviewed this Nuclear Medicine study personally, and am in full agreement with the findings of the report presented here.
