Pre-Examination Instructions

scan of babies face Preparation for your Diagnostic Ultrasound Examination

Ultrasound is a noninvasive diagnostic procedure which enables your technologist or physician to visualize your internal anatomy without the risks associated with x-ray.

One should know how to properly prepare for the ultrasound exam, if the best results are to be obtained.

First Trimester Obstetrical Examination

For this examination, a full bladder is most important. We recommend that the patient drink 24 ounces of liquid prior to this test. Remember that the goal is for you to have a full bladder, not be in pain.

Second Trimester Obstetrical Examination

For this test, a partially full bladder is required. The best way to accomplish this is to drink 24 ounces of liquid 30 minutes prior to the examination.

Third Trimester Obstetrical Examination

At this point of pregnancy, a full bladder is not required. We would recommend that the patient not urinate one hour prior to this examination. No need to drink water for this test.

Vaginal Ultrasound Examination

No special preparation is required for this type of ultrasound examination.

Food Prior TO Obstetrical Ultrasound

I recommend that 30 minutes prior to examination that a patient partake in at least a snack containing natural sugar. If your appointment is within one hour of a proper meal, a snack is not needed.

Recommended snacks:

Fresh fruit or fruit juice. If your doctor has recommended a special diet for you, never consume foods that you are instructed avoid. Example: Diabetic diets.
