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

Less tha an hour: And probably more like 30 -40 minutes, maybe not even this long. I think it has to do with how new the machine is. Some very new machines have faster acquisition times. The radiologist should be able to provide a more exact answer as to the length of time for this imaging test. ...Read more

If I have a CT scan w/contrast done on Thursday and bone scan done the following Monday will the contrast effect bone scan results?  If so how?

Probably not: CT scan is an IV contrast to arterial vessel of organs. Bone scan uses a radioactive tracer to look for abnormalities in the bone. They are 2 different substances. ...Read more

How do bone scan and a pet scan differ?

Tracers..: The tracers are different. Bone scan usually uses TcMDP and PET scan uses F18-FDG (glucose). The bone scan is good for showing osteoblastic bone lesions and shows increased bone activity around a metastasis but not the actual metastasis itself. The PET can show glucose uptake in the actual tumor itself. PET is better for lytic bone lesions. CT part of PET/CT can show lytic and blastic lesions. ...Read more

How are mr scan and a CT scan different?

Contrast difference: Ct uses a combination of xrays shot from multiple directions to look at differences in tissue density. Mri uses strong magnetic fields instead of xrays to differentiate tissues and gives much better contrast than ct. Ct is typically used in the acute setting to see if there is blood or major abnormalities. Mri is a more specific exam to differentiate abnormalities such as stroke or tumor. ...Read more

How long do the negative results of a head scan remain relevant if, a month after the scan, the same headaches that prompted the scan have returned?

How long do the negative results of a head scan remain relevant if, a month after the scan, the same headaches that prompted the scan have returned?

CT rarely useful: While ct of the head is almost always ordered by an er doctor when a person goes to the er with new severe headache, a repeat ct after a negative study (assuming it was done with contrast) is rarely useful in the diagnosis of headache.

How does metal affect the results of a pet scan?

Usually not much: Metal can block the gamma rays that are emitted by the patient, and block the xrays from the ct portion of the pet/ct, which can create errors on one portion of the exam (called the attenuation corrected scan). However, the original pet data from the scan (uncorrected) is always available for review, so if the standard images have artifact on them, the uncorrected images can be reviewed. ...Read more
