Ct Scan With Contrast Vs Without Contrast
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
Could a CT scan with contrast affect a estrogen test the following day? Could it cause it to be low
Not likely: Estrogen levels fluctuate depending on where you are in your menstrual cycle. If your estrogen was very low (in the menopausal range) your fsh level should generally be high. If your fsh was not checked, or it was checked and was nomal, I would just consider asking to have your estrogen level retested. ...Read more
My sister went for a CT scan with contrast and because her creatine was too high they couldn't do it. WHY???
Is it rare to have to take a second CT scan with contrast because the contrast did not reach the lower left quadrant?
This is common.: When you drink contrast for a CT scan, it may take a long time for your intestines to get the contrast from the stomach to the rectum. Typically, CT scans are done 1 hour after you've begun drinking. This can be enough time to fill most of the bowel, but not all of it. Radiologist may request a 2nd scan if there is some question about the colon that wasn't answered on the 1st scan. ...Read more
I have a CT scan with contrast they told me not to eat or drink 4 hours before. But I forgot and I ate. What will happen?
Likely nothing: The old protocols for a ct scan with contrast stated that there should be nothing by mouth 4 hours prior to the study. The rationale was to prevent vomiting thought to be caused by the intravenous contrast. The contrast agents currently used have very little likelihood of causing vomiting, so most centers will now allow you to drink clear liquids prior to the study. Still best to avoid solids. ...Read more

How long doez it take for results of CT scan with contrast. I had it Friday am. No results so far. Saw something on liver?
Commonly: It may take several days for an imaging study to be read, if it was ordered "STAT". In many cases, a study completed on Friday, particular if completed late in the day won't be read until sometime on Monday. If you are worried, please consider contact your the ordering physician's office in regards to the results. Best of luck. ...Read more
I have a CT scan with contrast and I was not supposed to take metformin for 48 hours but I accidentally took 1 yesterday morning will I be okay?
Likely - see ans.:
You likely will be fine – that said, the theoretical concern is that iodinated contrast could impair renal function and therefore you could not appropriately excrete the meformin /metabolites causing an extremely unusual condition of lactic acidosis.
The american college of radiology recommends the following based on your clinical category (you should discuss with your dr.):

Just had a CT scan with contrast dye for my shoulder two day ago, since then I m getting pains on my left and right lower side that comes and goes?
Likely unrelated: Ask your doctor to check your kidney function if you need reassurance. The contrast material used for ct is quite safe but may in rare instances affect the kidneys, more commonly in diabetic patients. Most radiology facilities screen patients prior to the exam to insure the safety of using the contrast media. ...Read more
CT will show mucus: In your sinuses if it's there, as in a sinusitis infection. It is not good at showing phlegm in your throat, however. If you cough up phlegm, then you have phlegm! ;-) CT can show some serious reasons for headache such as bleeding or tumor, but most people with headache have a completely normal head CT. We can only see disease, not the headache itself. ...Read more
Ct scan with contrast saw soft tissue mass next to bladder. Mri with contrast saw nothing. Why is this?

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 more
I have multiple liver masses with hyper dense margins on CT scan with contrast. Is it possible that they are benign?
No: If your sling or mesh is too tight, then you will have issues with difficult urination, abnormal urination, and/or pain (most commonly). No imaging study can show how 'tight' a sling is. It is very difficult to properly visualize mesh products for defects with any imaging modality currently. The best evaluation is a proper history and thorough examination, and possibly urodynamic studies. ...Read more
Would it be wise to take Benadryl (diphenhydramine) 50mg before CT scan with contrast just incase of allergic reaction?

Is there a lot of radiation associated with a CT scan with contrast for the renal area? Can the contrast cause an allergic reaction?
No: CT of abdomen is a fairly routine test and not considered a radiation danger. Th incidence of allergic reaction to contrast is 1-3% with non-ionic agents and 4-12% with ionic contrast agents. Non-contrast agents are the type generally used today. The benefit from the diagnostic value of the test far exceeds the risk of these 2 issues. Hope this answers your question. ...Read more

I have noticed bilateral supraclavicular bulges, most notably when arms are extended or shoulders pulled back. CT scan with contrast of neck showed nothing. Bloodword normal. What could this be?
My husband has been having pain on the left side of his torso. There's a kind of mass there. He's also having back pain. He went to the e.R. 2.5 weeks ago; they did a CT scan with contrast that showed nothing. He saw a surgeon who said it's not an ulc

Possibly: An abdominal CT examines the abdomen from the belly button up to the bottom of the chest. A pelvic CT examines the body from the belly button to the bottom of the pelvis. The test for the 'abdomen' is generally ordered as CT of the abdomen and pelvis with and /or without contrast. A CT of the abdomen and pelvis should detect a hernia. Sometimes an ultrasound is ordered in addition to and/or instea ...Read more
My doctor ordered a CT scan with contrast. I am on thyroid meds and worried about the dye/contrast. What can I do?
No worries: There is not a concern, if the ct is evaluating other parts of your body, including the neck. The contrast will not cause a problem with your thyroid or your medications. But, you don't want to do this type of ct scan, if your doctor later plans on evaluating the thyroid itself with a radioactive uptake nuclear medicine scan because it can interfere with that and skew the results. ...Read more
Hi dr! I want to ask. Is it possible that a kidney stones was seen in ultrasound but can't be seen in ct scan with contrast?
Yes, because: It had probably passed in the meantime. Small stones generally pass. Most important for you is to prevent recurrence of stones. ...Read more
Is a CT scan with contrast accurate for locating a blood clot in my chest? My results showed normal but my d dimer was elevated.
The sensitivity: Of CT (tailored for PE) for detecting PE is 80-90%. If the clinical probability of PE is high, and the CT is negative, further workup may be necessary. ...Read more
If MRCP & CT scan with contrast were clear of Pancreatic Cancer, what are chances EUS can find Pancreatic Cancer? Are odds on my side with clear MRCP?
Pancreatic cancer: Was the CT tailored for pancreatic mass protocol? If so it is highly accurate for detecting even very small panc masses. If it was a routine CT, the accuracy is still high, but very small tumors may not be seen. MRCP is also not specifically tailored to look for panc mass, so very small lesions may not be seen. No test is 100%, so it is always possible that another test could pick something up. ...Read more
Would CT scan with contrast show abnormalities of the fillopian tubes? Like scarring or blockage. This was an abdominal scan.
Unlikely: Ct with contrast could show a swollen/dilated tube (hydrosalpinx) and 'might' be helpful for suspecting an abnormal anatomic placement of a tube, but should not be considered reliable for evaluating tubal blockage or presence of adhesion (scar.) the hysterosalpingogram (hsg) is more useful for evaluating tubal blockage, and laparoscopy or laparotomy with tubal perfusion is the gold standard. ...Read more
