Mri Pituitary Without 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 moreSee 1 more doctor answer
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
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 moreSee 2 more doctor answers
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 bases on scan slice thickness or it may not stand out within the normal tissue. ...Read moreSee 2 more doctor answers
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

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
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 moreSee 1 more doctor answer
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
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
