Lumbar Spine Cat Scan
If spine dr says my lumbar spine looks normal on CT scan, is a cortisone shot still benificial for true sciatica pain?
CT scans: are typically not very useful in determining any main issues in the spine. you need an MRI to really determine what is awry in you causing your sciatica pain. If there is pathology the MRI will show it. Then and only then can you be sure an epidural may help you. ...Read moreSee 2 more doctor answers
Ct scan uses data from a beam of xrays and reconstructs a cross sectional image of your body. It is a high dose of xrays and used only when the benefits outweigh the risk. Cancer risk is 1 in 500 in children. Also using iodinated contrast might cause transient renal failure in about 5% of patients. (contrast induced nepropathy) most do not explain this to the patient as ...Read more

"Contrast" : "contrast" is a preparation that is used in medical imaging to increase the visual difference between similar or adjacent tissues. Contrast can be as simple as frothy salt solution, which is useful in some ultrasound studies, or much more complex, such as the gadolinium-containing molecules used for contrast in MRI studies. Ct contrast contains iodine, an element whose properties block x-rays that are used in the ct scanner. Common benign responses to iodine-containing contrast includes flushing (a pretty noticeable sense of warmth) and a metallic taste in the mouth. More profound responses include itching, hives, and swelling in the throat. These are called "anaphylactoid" reactions. The risk of anaphylactoid reactions can be reduced with medications like Diphenhydramine and corticosteroids. These sorts of reactions are common enough that radiologists and radiology technicians can spot them quickly, and all ct scanning suites are equipped to deal with them. Seafood and topical iodine allergies are not predictors of who will develop an anaphylactoid reaction to ct contrast (although this is a widely-held erroneous belief). Another response to ct contrast is kidney injury. The risk of kidney injury might be reduced by things including avoiding certain medications and keeping well-hydrated prior to the procedure. Concerns regarding reactions to ct contrast are valid, and should be addressed with the physician who orders the test as well as the physician who is responsible for performing the test. ...Read more

The lumbar part of the spine is the low back. It is made up of five bones (most of the time) stacked one on top of the other. They are connected by disks, facet joints, and ligaments. These soft parts allow for movement controlled by the spinal muscles; the muscles can also keep it stiff when need be. The lumbar spine also contains and protects nerves to ...Read more
