Is bladder scan and bladder ultrasound the same?

This ultrasound procedure is also referred to as bladder scanning or BladderScan®, which is the brand name of a popular, portable bladder scanner. Bladder scanning is painless for the patient and eliminates the risks associated with unnecessary catheterization.

Is there an alternative to CT scans?

Still, the most common alternatives to CT scans are ultrasounds and MRIs. Unlike CT scans, neither uses ionizing radiation. Ultrasound constructs a picture using sound waves; MRI uses magnetic fields to produce an image that often has greater clarity than a CT.
