Is it normal to have white under & behind a pituitary gland on MRI no contrast?

Is it normal to have white under & behind a pituitary gland on MRI no contrast?

Probably: I assume you are referring to the area surrounding the pituitary. This is the sella turcica, the portion of bone which protects it. At the posterior (back) of the pituitary, there is also a "bright spot" which is part of normal pituitary tissue. There are two completely different tissue types that make up the pituitary and they look different on mri. ...Read more

Mri (Definition)

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

What can cause the pituitary gland to show up bright white on MRI with out contrast?

What can cause the pituitary gland to show up bright white on MRI with out contrast?

Posterior Pituitary: The posterior pituitary has intrinsic high t1 signal. It's thought to reflect the high concentration of neurosecretory granules in the neurohypophysis (posterior pituitary which stores/releases oxytocin ; vasopressin produced in hypothalamus). Absence of the normal posterior pituitary bright spot should prompt a search for an ectopic posterior pituitary that has failed to migrate from hypothalamus. ...Read more

Can MRI without contrast see pituitary tumour from cushings?

Can MRI without contrast see pituitary tumour from cushings?

Yes it might: If it shows, then it has been useful. But one can not exclude its presence if no contrast was used. So if there is strong suspicion, then a repeat MRI with contrast may be more certain and more definitive study to rely on. ...Read more

Could a MRI with contrast fail to identify a pituitary tumor?

Could a MRI with contrast fail to identify a pituitary tumor?

Yes: Most pituitary tumors are "microadenomas", meaning that they are less than 1 CM in size. Mris done specifically to look for a pituitary tumor are very good at detecting tumors near 1 CM in size, and identify about 50% of tumors in the 0.3 CM size range, and would miss most tumors smaller than this. ...Read more

What does a MRI of the pituitary gland check for? What kinds of abnormalities does it detect? Mri is without and then with contrast

Pituitary anatomy: Greetings, a pituitary MRI +\- contrast is done to evaluate the potential causes of pituitary hormone abnormalities. Typically, this would be looking for a pituitary adenoma, a benign tumor that can make excess hormones (eg-Prolactin) or damage the pituitary resulting in low hormone levels. Inflammation or a condition called an "empty sella" can also be seen and result in hormone problems. ...Read more

Can a CT and MRI without contrast detect a pituitary tumour?

Can a CT and MRI without contrast detect a pituitary tumour?

Yes it could: Ct is more dependent on contrast. But MRI has two phases (t1and t2) which can serve like a contrast and the tumors often show up better in t2 weighted images. ...Read more

If I had a pituitary adonema would a standard brain MRI with and without contrast show it?

If I had a pituitary adonema would a standard brain MRI with and without contrast show it?

Maybe: Pituitary adenomas MRIs are very specific protocols. If you have a 'macroadenoma' which is larger than the normal gland, a routine MRI protocol would still likely show this. However, 'micoadenomas' can be only a few millimeters in size and a routine brain protocol MRI could miss it based on scan slice thickness or it may not stand out within the normal tissue. ...Read more

I'm 68 year old female. Weight 145, Height 5'7". IGF-1 level 196. Had brain MRI w/contrast. Pituitary normal, no tumor. Is this level too high for me?

IGF: Values of IGF-1 for your age are low 65 ng/ml, median 110 and high 95th percentile is 188. Your level is not that above upper limit of normal. Actually I have a strong interest in Age Management Medicine and would consider this good. However, I do not know if you are symptomatic or not. Hope the data helps! ...Read more

MRI: Mri machines can vary greatly in quality and in their ability to distinguish a very small lesion in the pituitary gland. Most microadenomas show up as small areas of decreased enhancement compared to the rest of the gland. These small areas can also be artifact, cyst, scar etc. It is possible but unlikely that the radiologist misread the scan. Finally, most microadenomas are biologically active and produce a hormone. Without an endocrine abnormality, the lesion is less likely to be a microadenoma. When there is doubt clinically, a follow up scan in a few months is advised. ...Read more

Pituitary adenoma in MRI so what is next?

Pituitary adenoma in MRI so what is next?

Endo and NS: An endocrinologist has to determine if the adenoma is functional. If a prolactinoma, even if large, medication is started before considering surgery. Other pituitary hormones have to be assessed as well. Cortisol and thyroid hormone deficiencies have to be replaced before surgery. Hydrocortisone is usually administered prophylactic ally if surgery is necessary. Size and symptoms important also. ...Read more

Would an MRI be able to show pituitary cancer?

Would an MRI be able to show pituitary cancer?

Perhaps: Mri of the brain with contrast (gado) can show a pituitary tumor but it won't always distinguish cancer from benign tumor. You will need a biopsy (surgical) to fully confirm the diagnosis. Please discuss fully with your neurosurgeon. ...Read more

What conditions affecting the pituitary gland would show up in an mri?

Adenoma: A pituitary protocol MRI is designed to evaluate the pituitary gland. It is used to assess for adenomas, cystic masses, mixed cystic and solid masses, and dural based lesions such as a meningioma. The morphology of the pituitary gland is also evaluated to rule out structural abnormalities. ...Read more

What is borderline thickening of pituitary stalk mean it was a result from pituitary MRI?

Probably not signifi: You have to interpret Radiology results in the context of symptoms. What symptoms did you have that prompted the MRI? And did you ask the doc / Radiologist who did the MRI this question? Most of the time, a slightly thickened pituitary stalk is meaningless - it tells you nothing about symptoms or ur condition. However, if you've had certain neurologic / visual symptoms, it warrants follow-up. ...Read more

How common is it for pituitary tumors to be overlooked on MRI?

How common is it for pituitary tumors to be overlooked on MRI?

Unlikely: If your physician ordered a brain MRI to look for a pituitary tumor due to symptoms that you reported, then the radiologist would specifically look for one. Thus, it is unlikely. If you're concerned, you can have your physician take a look at the CD of the brain MRI for a second opinion. Http://radiopaedia. Org/articles/pituitary-mri-an-approach ...Read more

Hi I have a question I had a MRI done and they found a cyst in my pituitary I was wondering how they treat it it is 5mm x 2 in size, ?

Follow with mri: You need to check to make sure this "cyst" is not producing extra hormones. If it's non functioning, which it most likely will be, you will need to follow it serially with MRI and monitor for changes. Autopsy studies have shown that up to 10% of the population could have something in their pituitary and don't know it. ...Read more

Why do doctors do an MRI of the pituitary gland?

Why do doctors do an MRI of the pituitary gland?

Pituitary: I assume that other hormones driven by the pituitary may be abnormal based on history, examination, and labs. The pituitary has a role in control of many hormones. There is a feedback loop between the pituitary and the different tissues that make hormones controlled by the pituitary. The MRI will show if the pituitary looks normal or not. ...Read more

What are other tests like MRI of pituitary and cosyntropin stimulation test. Anyone had similar experience?

Ask logical question: Hi. I'm sorry, but your question makes no sense, What is "like MRI pit. And cosyntropin test"? They're unique, nothing else like them. What are you trying to ask? My guess (& I hate to guess) is that your doc is wondering about your adrenal function. Cosyntropin looks for primary adrenal failure, whereas pit. MRI looks for pituitary (secondary) adrenal failure. Maybe see an endocrinologist! ...Read more

Hi! If you do an MRI of the pituitary can you also see if there would be something wrong in the other parts of the brain?

It depends: Different parts of the brain can be imaged by MRI. If what was ordered was a limited sequence it might not show the entire cortex through the brainstem - you will need to ask your doctor what was ordered specifically. ...Read more

What can a MRI show on pituitary glands? My wife is going to get an MRI done to examine her pituitary gland. If there is something wrong with her hypothalamus instead, would the MRI also show that?

Yes: Pituitary gland mris are used to discover tumors of the pituitary gland. These are usually benign. Parts of the brain including the hypothalamus are also seen. Since some pituitary tumors grow and expand into the brain, the nearby brain structures are always included in the study. Some centers include the MRI of brain with pituitary if its the first study. ...Read more

What does a pituitary MRI report tell a doctor?

Pituitary anatomy: Hi. The high resolution pituitary MRI has revolutionized pituitary endocrinology along with our highly reliable pituitary hormone assays. Pituitary MRI only gives info about anatomy. Using gadolinium contrast is very helpful, but still only gives anatomy info. We see pituitary tumors, infarct, etc. Or nothing. All imaging modalities have their limits of resolution. I hope your pituitary does well! ...Read more

What does this MRI mean? Pituitary is with adecuate location and size with preserved signal intensity but with hypersignal on neurohipophiza

Meaning of MRI: MRI- Magnetic Resonance Imaging. It's a machine that takes very high resolution pictures in the body. In this case the picture is of the pituitary gland which is divided into a portion "in front" called the ADENOHYPOPHYSIS and another "in back" called the neurohypophysis. Your physician will tell you what the results mean when talking about signal intensities etc. ...Read more
