CT uses aqueous dipotassium hydrogen phosphate (K2HPO4) as its calibration standard, whereas DXA (dual-energy x-ray absorptiometry uses calcium hydroxyapatite (CaHAP). The doctor is relating the CT results to the standard used in CT analysis. QCT is a volumetric measure, while DXA is a two-dimensional measurement. The spine axial bone density of this patient was equivalent to 80 mg/cm^3 of K2HPO4, the reference standard for CT analysis.
I had this surgery. It runs about $12,300 in the Chicagoland area. I had to get a CT scan and an MRI before. The CT I think was around $2300 and the MRI was $4000. You also have a bunch of doctor's appts and X-Rays. The surgery runs ~ $25,000 in the San Francisco Bay Area, circa 2009.
This is a proceudre they do under light sidation to test the spine actually pain. The doctor uses a needle, inserts it where the pain is, and injects a die to see inside of the spine better then a CT and a MRI. You can detect if pain is true.
yes
I would say Sherman Health is a good hospital for cardiac ct scans. Lots of hospitals have good ct scans, but you really need to look at the doctor more not the hospital.
CT or ultrasound can be used to guide the doctor in selecting the best location for obtaining the biopsy sample.
Yes and/or no. This depends on what the test is looking for and the policies of the place doing your CT and your doctor. Always talk to your doctor about alternatives and what is best for your case. For some CT tests, the oral prep (drink) is of minimal concern. For some CT tests it can be the main concern.
No. They would only have you do that if they were planning on using anesthesia for some other reason. Food content won't affect a CT.
Talk to your doctor.
An InstaTrak CT refers to a CT or CAT scan, usually of the sinuses, which is done prior to performing a sinus surgery in which the surgeon will use the InstaTrak Surgical Navigation System. Although the majority of CT scans for the InstaTrak are done for sinus surgery, some Neurosurgeons will order a CT scan for a brain surgery. This is usually rare because for most brain surgeries, the surgeon will utilize an MRI scan with The InstaTrak which will typically show the detail of the softer brain tissues better for the surgeon.
No. The doctor will ask you to urinate during the CT scan itself in order to get an accurate image.
CT myelography (a test in which dye is injected into the spine) may demonstrate the cerebrospinal fluid flow between the spinal subarachnoid area and the cyst.
