Question 1

i am scared if having a negative reaction to contrast dye (iv) for a ct scan. how safe is the dye and are their other tests that can distinguish liver lesions without contrast dye?

Accepted Answer

: If you are not allergic to iodine and have not had reactions to previous imaging contrast agents, there is little risk of a reaction this time. The danger of an important health problem from mis-diagnosed or under-diagnosed "liver lesions" probably is far higher. Discuss with your doctor or radiologist if you remain concerned.

Question 2

i had a ct with contrast/dye it showed i had a cyst/hemangioma on liver.had an ultrasound. it stated: long axis right lobe 18cm with bulbous contour of the inferior portion of the right hepatic lobe similar to ct scan. what does that mean?

Accepted Answer

: That’s just describing the shape of the liver and what they saw. It would probably be best interpreted by whichever doctor ordered the tests.

Question 3

what is the dye commonly used for a liver scan?

Accepted Answer

Depends on scan?: There are multiple types of liver imaging available. Ultrasounds don't use any dye. Cat scans use iodinated dyes. Mri scans use gadolinium based dye.

Question 4

i have liver mri where gadolinium dye will be used. should i do kidney function test before mri?

Accepted Answer

: If you are worried -yes.

Question 5

can a ct scan without the dye tell the difference between liver nodules and cysts?

Accepted Answer

Depends: Finding a liver lesion on ct depends on the attenuation difference between the lesion and normal liver.On noncontrast ct many liver lesions usually are not visible, since the contrast between lesion and the surrounding liver parenchyma is too low.Round lesion measuring water density on noncontrast ct is most likely a simple cyst.However, dedicated liver ct or MRI is the way to go when there is a ?

Question 6

i had a liver biopsy and have had terrible pain when i breath since. i had a dye-ct scan which was negative. why such pain?

Accepted Answer

Biopsy approach: Depending on approach to the liver, you can sometimes stimulate a nerve (did they go between the ribs?).  Also, the capsule surrounding the liver is very sensitive and difficult to numb.  The pain should go away, but may take time.  So long as you feel ok, and the pain is not increasing, you can use whatever meds your doctor suggests.

Question 7

thick blood , high inflammation levels  abnormal liver function in all 3 blood tests, test  back pos for blood clot on lung after dye test, back neg?

Accepted Answer

This is serious: I trust the dye test was a pulmonary angiogram that demonstrated a pulmonary thromboembolus, and it has also been determined that you have hypercoagulable blood. This is a major problem that will require work with your primary care physician and probably long-term medical management -- more than healthtap can do. Hope you do not smoke. The "inflammation" & liver labs need to be addressed in time.

Question 8

Accepted Answer

Question 9

Question 10

Accepted Answer

No: Hydrate well after the IV contrast and it will be flushed out by the kidneys, .
