Description
Estimated cost for Cranial CT Scan at general public hospitals in China is about ¥210-640, and at Grade 3A hospitals about ¥300-800, varying by hospital tier and region.
Main Uses
Head CT scans are primarily used for: 1. Diagnosing and evaluating acute neurological conditions like stroke, 2. Detecting and assessing brain injuries, 3. Identifying and monitoring brain tumors, 4. Evaluating causes of headaches, 5. Assessing the extent of brain damage after trauma, 6. Planning for neurosurgical procedures.
Normal Range
A normal head CT scan shows no abnormalities in the brain, such as tumors, bleeding, or signs of stroke. The density values (Hounsfield Units) for different tissues typically fall within specific ranges: air (-1000 HU), fat (-50 to -100 HU), water/CSF (0 HU), blood (30-60 HU), and bone (+400 to +1000 HU).
Low Values - Possible Causes
Low density areas on a CT scan can be caused by: 1. Cerebral edema, 2. Infarction or ischemic stroke, 3. Presence of cysts or fluid-filled spaces, 4. Fat deposition, 5. Certain types of tumors that are less dense than surrounding tissue.
High Values - Possible Causes
High density areas on a CT scan may indicate: 1. Hemorrhage or bleeding, 2. Calcifications, 3. Tumors with high cellularity or calcified components, 4. Bone fragments within the brain, 5. Contrast agent if used during the procedure.
