If the area where the plastic tube (IV tube) was placed inside your vein is red, swollen or sore, you should put a warm, wet towel on the area four times a day for 15-20 minutes. If swelling continues for more than 48 hours, you should call your doctor. If you are breastfeeding, it is safe to continue to do so. After your CT scan you will be observed for any complications by the hospital staff.


Is it safe to do a CT scan during Pregnancy


CT scans are safe procedures and, in most cases, the benefits of having a scan outweigh any potential risks.

A CT scan does expose you to radiation. The amount is small and will not cause you any harm. However, CT scans are not recommended for pregnant women because there is a small risk that the X-rays that are used could harm the unborn baby.


Prepare for an Ultrasound (Sonography)


For most ultrasound scans, special preparation is required. You should continue with any of your usual medication. Wearing comfortable and loose fitting clothing is also advised. You may also be asked to remove any jewellery.
In some cases, there may be more specific instructions, which will depend on the type of scan being carried out. For example, if the organs in the abdomen are being assessed, you may be asked to have nothing to eat six (6) hours before the examination. Consequently, for a pelvic ultrasound drink two (2) pints of clear fluid or fruit juice one (1) hour before the examination and do not empty the bladder


Ultrasound imaging, also called ultrasound scanning or sonography, involves exposing part of the body to high-frequency sound waves to produce pictures of the inside of the body.
