Ct Lumbar Spine With And Without Contrast
Maybe: Mri's are very focused exams. To get the best quality imaging of the area of interest, the field of view is limited as much as possible. The trachea may have been included, but not necessarily. You should speak with your doctor or the radiologist that read the study and ask them to look at the trachea. If it is seen, they can answer your question and if not they can recommend another test. ...Read more

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
Will a CT scan of the lumbar spine post fusion without contrast show pinched nerves or just bone structure and hardware?

Doubt it: If any irregularities in the intestinal wall were found, it would be just that, irregularities. Their presence would suggest a problem but the overlap with other possible conditions would make the information inconclusive. A normal study would also not rule out the condition. ...Read more

My dr. Has ordered a CT scan with contrast for the cervical and thoraicic area. Does this involve a spinal tap?
No: They will give you an IV contrast material; spinal taps are not usually a part of this procedure. Sometimes a ct myelogram will be performed by a neurosurgeon and they will inject into the spinal canal. If your not doing a myelogram then there is nothing worry about a spinal tap. ...Read moreSee 1 more doctor answer

Need to talk with : Your ordering doctor. Depends on what is being evaluated, and the differential diagnosis. Ct is a good quick screen for bleed, masses, skull fractures, etc. And MRI gets you good soft tissue details, and lets you better evaluate the gray and white matter, also allows you to evaluate bleeds, helps you tell if old or new bleed, also helps you see tumors, strokes (ischemic areas, atrophy, etc.). ...Read moreSee 1 more doctor answer
Depends on problem: Much can be learned from MRI without contrast but if a vascular anomaly or tumor is suspected the IV dye helps to show the extent of the lesion and it's location in areas that are not well delineated without the dye. If your doctor recommended it, you should go ahead and have the dye injected. Avoid it if you are allergic to the dye. ...Read more
Have 5-6 mm calcified lump in the posterior neck, doctor recommend imaging. Should do MRI with and without contrast or CT w/ contrast? Benefits/risks?
Neither!: If you know the lump is calcified, you're best off not doing any imaging. If you want to know what it is, go to a surgeon or pathologist who can manage a simple biopsy, probably in his office, to figure out what it is. A FNA (fine needle aspiration) may work out for you. If you REALLY need to know if it is solid or a cyst, then ultrasound is better. CT involves radiation. MRIs are $$. Avoid them. ...Read moreSee 2 more doctor answers
