Aortic stenosis is typically followed using repeated ultrasound scans. Brain damage is confirmed following MRI or CAT scans. CAT scans and MRI can also be used. They also had functional MRI scans taken during the experiment. Risks and discomfort may be associated with MRI scans. Cancers are in general investigated through the use of CT scans and MRI scans. A few cases of burns on tattoos caused by MRI scans have been documented. There are scans and test to verify vWD. The radiation doses received from CT scans is variable. Avoiding unnecessary X-rays (especially CT scans) reduces radiation dose and any associated cancer risk. Treatment starts with a series of brain scans. Endpoint Protection scans computers for security threats. Multiple, closely spaced 2D scans are taken of the target area. The indexer scans through text columns in the database. The brain then quickly scans the area, to explain the pounding, and notices the bear.
