Rachael McEwing, a radiologist who is on the Maternity Ultrasound Advisory Group, said because unnecessary dating scans were being carried out, some women who really needed scans may not be able to get an appointment.

The answer is simple: one of the most common areas on the body to be examined through an ultrasound scan is the abdomen. Depending on the internal structure that is to be scanned, the bladder may need to be full for better visualization. This is because of the nature of sound waves and the way they move though different mediums such as air or fluids.
If you have ever had your head underwater, you may have noticed that sounds are more muffled. In the same way, your bladder acts as a reservoir of fluid, which helps the sound waves bounce back for better visibility and more detailed images. In such cases, you should not empty your bladder, because the extra fluid is necessary for the ultrasound. Not every ultrasound requires a full bladder. It really depends on the specific body area being imaged.
Fluid can increase visibility in some cases, but it can also obstruct the view of some internal structures. There are only a few ultrasound scans that require you to have a full bladder, and your doctor will inform you when the time comes if yours should be full or empty.
