What are the differences between an mri, mra and mrcp?

What is studied

Mri
MRI (magnetic resonance imaging) looks at tissues/organs. MRA (magnetic resonance arteriogram) looks at arteries, for example to evaluate for an aneurysm. MRCP (magnetic resonance cholangiopancreatography) looks at the biliary system (involving pancreas, gall bladder, liver).

Dr. Thomas Graber answered:

Can you have a stone in bile duct if GB removed 15 yr ago? US showed a poss 4mm stone. MRCP showed dilated hep duct 14mm no stone. Awaiting results MRI with contrast. RUQ pain and nausea. Labs norm.

It's Possible

You CAN have a stone in your duct. It sounds like you are doing a good job getting it checked out. The main question is to understand your symptoms and your options for relief of those symptoms. Keep pursuing an answer. If it's NOT a stone, you want, at least, to know if you have something that's important to treat.

What's the difference between a MRI and hip arthrogram? I had an MRI scan done on my hip and it didn't find anything. But I still have SEVERE hip pain. The doctor has ordered a hip arthrogram. What's the difference?

Dye!

Open-uri20130118-601-1qw63rn
Dye is injected into the hip looking for tears in the capsule and labrum. Then an x-ray or CT is done to visualize what is present! Not done routinely for joint pain or arthritis!

What's the difference between a CT scan of head and MRI.?brain zaps,eyes jump back and forth,panic,confusion at times.doc says I'm ok don't need MRI.

Both show anatomy

Brain
Both CT and MRI show anatomy. CT does this be imaging differences in density, and MRI by looking at differences in the number hydrogen atoms in a region (Proton density) and the local environment they are in. Both are very good, but MRI is better for looking at soft tissues.

What's the difference between a PET scan and a MRI? I hear these terms used all the time by my doctor regarding testing, and I'd like to know what the difference is between the two.

Anatomy v Physiology

Open-uri20130507-5570-l5m81v
MRI and CT look at the structure of the body, the anatomy, and the way diseases change or distort it. PET looks at the physiology, or how the body uses, or metabolizes something. For PET, the most common metabolism pathway looked at is how glucose is used. A low dose CT is often acquired at the same time as the PET (as in PET/CT scan), to correlate the PET findings with the CT anatomy.

What's the difference between the CT head the MRI Brain scan?

CT vs MRI

Head-brain
CT's and MRIs can focus on different things. CT is typically used to view bone and look for bleeding while MRIs are used to view tissues. Also, CTs use radiation similar to xrays while and MRI does not expose the patient to any radiation. However, anyone with a magnetic metal in their body can not get an MRI, since MRI uses a large magnet.

What's the difference between MR enterograpy and MRI of abdomen. Which is better. I am having both?

MR enterography....

Abdomen
Is intended to better evaluate the small bowel, especially in patients with inflammatory bowel disease. A large volume of oral contrast is given to distend the small bowel so the mucosa and wall can be better evaluated. Dynamic sequences are also done to see if peristalsis is normal. A traditional abdomen MR is not as good in looking at the bowel, mostly because distension inadequate.
