Pituitary Mri With Contrast
What are the benefits of doing a MRI with contrast? I had one without contrast and it was normal. They are wanting to rule out anything in my inner
MRI: Some abnormalities are only visible when made brighter with contrast enhancement, others are more easily delineated or more accurately assessed. It depends what they are looking for. Sometimes contrast not necessary. ...Read more
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
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
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
I have an "unremarkable" pituitary MRI but think something is wrong with my hypothalamus. Would hypo affect pituitary?
Yes: Hypothalamic dysfunction is a problem with the region of the brain called the hypothalamus, which helps control the pituitary gland and regulate many body functions. ...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
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
Failed 5 IGF-1/acromegaly tests from 2% to 25% over upper normal range. Is GH suppression test or dynamic pituitary MRI best nest step?
First confirm dx: Before imaging a dx of acromegaly should be confirmed with a growth hormone suppression test. Only after the biochemical diagnosis of the pituitary disease is made should imaging be done. There are other reasons for pituitary abnormalities, including nonfunctional pituitary adenomas. Iit would be a shame to have abnormal imaging and an extensive work up only to find that the dx is not correct! ...Read more
Merely technical: Looking directly at base of brain and pituitary requires slightly different cuts and angles, as the focus is directed to a small area of brain, but the software and pictures are handled in a similar fashion. In ms, we tend to use specialized approaches, such as flair or double inversion recovery to see the white matter spots better. Not needed for pituitary views, usually. ...Read more
Signs of preg and blood work, shows no menopause etc, pituitary mri shows normal, upper lower ultra sounds and cat scan show normal neg preg test???
Nonspecific symptoms: Many pregnancy symptoms are nonspecific. They can be present in many conditions. The evaluation you describe is extensive, and since it's been negative, should be reassuring. At this point usually the best approach is to follow the symptoms over time to see if anything new appears down the road. Testing can't always explain the cause of symptoms, but can usually rule out the serious stuff. ...Read more
A brain MRI found a 4x6cm lesion in the puitary gland described as a microadenoma. Two weeks later a pituitary MRI shows an 1.06x1.53 cm area of heterogenous gland described as a evolving pituitary adenoma or apoplexy. What is an evolving adenoma?
Check your units:
Frankly, I think you've got the original set of units wrong. You wrote 4x6 cm. MICROadenoma? Those dimensions are ginormous for something living in the pituitary gland. You mean 4x6 mm which then, GREW to 10.6 x 15.3 mm or what you wrote which is the same thing 1.06 x 1.53 cm. Evolving means it's changing/growing.

49 y/o male; testosterone measure 3x's, avg 174. Pituitary MRI neg. Prescription of fortesta 1 pump daily. 6 hrs. After dose extremely sleepy. Dosage too low?
Low T4 (2.4mug/l), ft4 (0.6 ng/dl), T3 (liothyronine) (40 ng/dl) and ft3 (2 pg/ml) TSH (4.7 uiu/ml). Other harmones stable. Should I get pituitary MRI done?
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
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
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
Does a head MRI both with and without contrast show if there is a problem or tumor in the pituitary gland?
Pc ordered nei of pituitary gland. Said its normal. Will the brain also be studied for other abnormalities from mri? Used contrast dye.
What r the symptoms?: What are the complaints that caused these tests to be done? Too broad a question to answer without more information. ...Read more
Had brain MRI no contrast. The tech said she was concerned I had a abnormality on my pituitary gland cause it should up bright white. What does mean?
Pituitary: Follow up with your doctor. Most abnormalities of the pituitary can be treated but don't take what the tech is saying as having meaning beyond the fact that you should follow up with the doctor who ordered it. ...Read more
Had MRI today to look at pituitary gland he gave me a contrast material injection which is the dye andnow were injected my arm has gone green nd hurts?
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
Can a pituitary tumor disappear on its own without any treatment? I underwent 2 mris with a contrast. The first showed 5 mm pituitary microadenoma. The second, which was done 3 years later showed no tumor at all. Could it be that a radiologist misread th
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
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
What does enhancement pattern appears homogeneous and no focal signal changes on T2 images of the Pituitary mean on a MRI report of the pituitary?
Pituitary MRI: This is a radiological description of a normal pituitary gland. Homogenous simply means that there are no focal enhancing lesions that would suggest tumor. The pit. Gland is highly vascular and readily enhances or "lights up" with IV contrast ...Read more
