It Is Ok To Use Pulsed Magnetic Frequency Therapy After Mri Scan With Dye
I've had multiple cat scans with iodine dye. I'm getting an MRI with the dye tomorrow. Will this harm me?
Mri or magnetic resonance imaging is one of the more recently developed imaging modalities available to physicians. It uses powerful magnets to generate images. There is no ionizing radiation which is a major advantage over many other modalities. Mri is the best imaging exam that we have for most soft tissue and joint related problems. There are radiologists ...Read more
Not too Risky: The biggest risk would be an allergy to the dye. It is rare, centers knows the cross allergies, that is, red flags about people who are increased risk for an allergic reaction. Centers are also prepared to take appropriate in case there is an allergic reaction. There is also the risk from the radiation associated with the ct. ...Read moreSee 1 more doctor answer
Myoview stress test uses radioactive injections, is this dangerous? Some say it's an absurd amount of radiation. My need to change to a CT scan ?
It is not: an absurd amount of radiation. The average effective radiation is slightly more than a standard chest CT. A coronary artery CT angiogram, on the other hand, is nearly twice as much radiation as a myoview stress test, and doesn't provide the same information. The radionuclide used in the stress test, technetium 99m, has been safely used in medicine for more than 50 years. ...Read more
Have you use CO2 in your practice and has the outcome been just as good as contrast dye. do contrast dye need to be used to confirm patency afterwards?
CO2 contrast: Understand you are asking about CO2 angiography as an alternate to contrast dye-angiography. It is reported to result in images that are somewhat lower in quality. Patency demonstrated via CO2 angiogram would not need to be confirmed with dye - the reason to use CO2 is lost if it is followed by infusion of dye! ...Read more
Is it possible to become allergic to the iodine contrast used for CT scans if i continuously have them? Does frequency matter?
Does stealth sinus surgery=image guided? What is the level of radiation exposure for this procedure, if any? Concern if also had recent CT scan?
Is it ok to do throat MRI with contrast two times in 1-1/2 months? Is it safe for throat and kidneys due to contrast solution injection?
Can a ct angiagraphy ( ct with contrast dye) show a pica aneurysm or an aneurysm near the brain stem or cerebellum? I heard you need the angiogram with the catheter, but some doctors said that's not true and this is also good test.
I have to have an MRI of brain with gadolinium. I had a CT with contrast once which was a bad hot feeling. Is gadolinium easier to handle? And if est GFR is 83 ml/min should test kidney first?
Is an MRA done with an MRI Machine? Is a Tesla 3 MRI machine better than a Tesla 1.5 for MRA of brain or legs? I have both available to me locally.
3T is great for MRA: MRA is done in a MR scanner with the administration of IV contrast. One of the advantages of a 3 Tesla magnet is greater signal which is very helpful for MRA studies. If you have equal options, I would choose the 3T magnet, but you would still have a good diagnostic study with 1.5 Tesla which is still a standard at many facilities. ...Read more
I am getting a MRI of brain with and without dye.What can the dye show that no dye will not show?Im afraid of the dye.Last CT scan dye caused tremors.
MRI/Contrast: Mri of the brain demonstrates very detailed pictures of the brain. Under certain conditions, such as tumors or recent stroke or infection, contrast will show breakdown of the blood/brain barrier. The contrast used in MRI is completely different from ct contrast. ...Read moreSee 1 more doctor answer
My dr wants to do brain MRI without contrast. Checking for tumer and bleed. Is it just as accurate without contrast as it is with contrast ?
Had a negative brain MRI w/o contrast on 1.5 tesla.Still having MS type symptoms.would another MRI be helpful ?should it be w contrast or is w/o fine?
When to repeat MRI: If the MRI is normal, it would probably not be worth repeating for awhile. There is some value to using contrast and that is typical for MS protocol MRI. The 1.5 Tesla strength is fine though. People under consideration for MS as a diagnosis may have a repeat MRI after 6 months or so. Hope that helps! ...Read moreSee 2 more doctor answers
CT with contrast: Before the study, an IV will be started, through which the contrast ("dye") is injected. Usually a lumbar scan is done first without contrast and then a second time with contrast to enhance structures like discs, spinal cord, nerves. They may request a blood test of your kidney function to make certain your kidneys can deal with the contrast. ...Read moreSee 1 more doctor answer
