Ct Lumbar Spine Without Contrast
Will a CT scan of the lumbar spine post fusion without contrast show pinched nerves or just bone structure and hardware?
Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! the image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...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
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

It depends: on the "issue" in question. If it is simply a workup for back paiin, contrast is probably not needed. If it is a workup for tumor/metastatic disease, or postoperative spine, contrast would be very useful. ...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
