Question 1

In 2017 i was diagnosed with rare appendix cancer. that same year an oncological surgeon specializing in this cancer performed hipec with debulking. is a ct scan with contrast better than an mri for detecting other cancers that might crop up?

Accepted Answer

Hello. It depends on the kind of tissue what type of study is more specific (for example: "soft tissue" or small tumors is preferred MRI, for bones X-rays/scintigraphy), and some studies complement others. It's important you continue your follow-up consults with your oncologist, as they are the one you know your case the best, and they would ask for the pertinent studies if necessary.

Question 2

Whats better for diagnosing pancreatic cancer.... ct scan or mri? i've had normal ultrasound and ct scan with contrast. still worried.

Accepted Answer

In answer to your question, i don't believe an MRI has any advantage over ct for pancreas lesions.  You've had a normal u/s and a normal ct, so why are you concerned about a process that is rarely seen in folks your age? If a lesion is seen on ct, the best test for evaluation is an endoscopic ultrasound with biopsy.  Don't waste your life worried about what could develop.. Good luck.

Question 3

Whats better for diagnosing pancreatic cancer? ct scan or mri? 34yr male. i've had normal ultrasound and ct scan with contrast. still worried.

Accepted Answer

Thin-slice (3 mm) ct abdomen yields fine detail of pancreatic structures...  Blood tests including tumor markers: ca-19-9, ca-15-3, and CEA can alert the clinician for ca.  Also, ERCP w/ ductal brushings (though its endoscopy) can search for malignancy.  Finally, mrcp may add to the clinical picture, but 64-bit ct is slowly encroaching on the former's superiority.

Question 4

Can brain aneurysms be found with ct scan and contrast or must mri be used to diagnose. i was told my a&e ct scan with contrast 20 yrs ago showed good blood vessels as my brother was recently diagnosed with aneurysms would i need tests again?

Accepted Answer

Both can be used to diagnose brain aneurysms. If you are worried or have a strong family history then have it done.

Question 5

What is the difference between mri contrast and ct scan contrast ?

Accepted Answer

Mri contast gadolinium does not contain iodine while ct contrast contains iodine.  An allergic reaction to ct contrast does not mean that you will have a reaction to gadolinium during your MRI scan. True allergies to the MRI contrast are exrtremely rare; however, you may still experience some symptoms like feeling lightheaded or nauseated due to the injection. Good luck with the exam!

Question 6

Can diverticulum that are not inflamed be seen on mri without contrast instead of a ct scan in non urgent setting?

Accepted Answer

Asymptomatic diverticulosis is commonly seen on  imaging studies. However, diagnostic imaging performed specifically for div. disease is essentially limited to imaging of suspected acute colonic diverticulitis. CT has replaced contrast enema as the imaging procedure of choice for diverticulitis. Ultrasound  also  successfully used ,MRI has significant potential as a radiation-free imaging test

Question 7

Had a ct scan because of headaches. all good. said nothing to worry sbout.now they what a mri but expect to see nothing . im a worried to death. theyre doing with and without contrast. so worried. why both?

Accepted Answer

Small intracranial lesions will not always show up on an MRI without contrast. If both tests have your physician saying "nothing to worry about", and you are still concerned, obtain a second opinion with another neurologist/neurosurgical physician.

There is nothing in mentioned tests to suggest an aneurysm. Health related anxiety appears likely that you may further address with your doc.
