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.

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.

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.

Does a head MRI both with and without contrast show if there is a problem or tumor in the pituitary gland?

Does a head MRI both with and without contrast show if there is a problem or tumor in the pituitary gland?

Pituitary gland: Hi, yes, MRI is a very good imagining modality to evaluate posterior brain, but But MRI might not detect microadenomas that are smaller than 3 mm (about 1/8 inch) across, follow up imaging if there is any doubt could be helpful.

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.

Could be: Hi. It could be a hematoma or bruise. Maybe the IV needle damaged the vein and fluid went into the surrounding soft tissue. You might want to go where they did the MRI and show them. What is your pituitary problem they're doing the scan for?

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

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.

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.

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?

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.

Pituitary gland. 2014 27.8 2015 26.1 Is this cancerous and do I need MRI/do I go back in 3mths to draw blood again? Nothing else came back high.

Pituitary gland. 2014 27.8 2015 26.1 Is this cancerous and do I need MRI/do I go back in 3mths to draw blood again? Nothing else came back high.

Standard approaches: Unlikely to have cancer, but pituitary adenomas could be present, and perhaps you have non-secreting process. Usual approach to check MRI studies over period of time, and get blood studies based on MRI and clinical changes.

I have all the symptoms of Cushing's Disease, but my MRI shows a small pituitary gland. If my pituitary gland is small, why do I have a buffalo hump?

Look like Cushing's: Cushing's is diagnosed by demonstrating inappropriately elevated cortisol with blood, urine and saliva tests. Although pituitary tumors are the most common cause, adrenal and other tumors can do this. However, many people look like they have Cushing's but don't; Many people with metabolic syndrome have a cushingoid appearance. See your Endocrinologist.

I had and MRI due to amenorrhea and low progesterone, it shows pituitary gland smaller than usual. Does size affect function?

I had and MRI due to amenorrhea and low progesterone, it shows pituitary gland smaller than usual. Does size affect function?

Usually not: The size of the pituitary usually does not relate to the function. Some people have an "empty sella", where you cannot see the pituitary gland at all, but still have normal pituitarty function.

How concerning is 15 month old girl has frontal bossingwith pituitary gland height of 3mm and concaved on MRI? Please give Details? Is this serious?

How concerning is 15 month old girl has frontal bossingwith pituitary gland height of 3mm and concaved on MRI? Please give Details? Is this serious?

HealthTap Prime: This sounds like a very serious question, & it will be hard to answer in 400 characters. Use HealthTap Prime, and look for a Pediatrician (Pediatric Endocrinologist) or a Neurologist (Pediatric Neurologist) to help answer it. Some causes include acromegaly (measure GH); antiepileptics during pregnancy; & basal-cell nevoid carcinoma. Russell-Silver, Rubinstein-Taybi, or Pfeiffer syndromes possible.

8.5 yrs daughter with bone age of 11.5 yrs. Mri: diffused enlargement of pituitary gland 10.5x7.3x7.8mm with no focal lesion. How abnormal is the size

A bit tricky: The pituitary grows during childhood and peaks in the 2nd or 3rd decade. Most studies measuring pituitary size on MRI focused only on the height of the pituitary gland and find that the mean peak height is usually about 6 mm +/- 1 mm. More recent studies measure the actual volume of the pituitary with special 3d mri. The mean volume for 5-9 yo girl in one study was 336+/-113 mm3.

Do Pituitary gland tumours grow bigger fast or does it take long time for it to get bigger my doctor made me wait 6 months nd am still waiting for mri?

Pituitary tumors: These tumors are generally slow growing and rarely are malignant. As such it is not uncommon to them to be observed without treatment for a period of time. Often, an MRI is done 3-6 months after the initial diagnosis, and then every 6-12 months thereafter. It is always appropriate to discuss concerns about observation with a doctor.

Had MRI to look my pituitary gland to see if there is benign tumour have letter asking me to come in to have a trh and metoclopramide test what is thi?

Had MRI to look my pituitary gland to see if there is benign tumour have letter asking me to come in to have a trh and metoclopramide test what is thi?

Hi prolactin: Hi. I'm assuming you have high prolactin. Do you have breast milk production and have your periods stopped? I think the TRH and metoclopramide stimulation test is not necessary. If you DON'T have breast and you still ARE having periods, they need to check for macroprolactinemia; it does't need to be treated. If periods stopped & you have breast milk and prolactin is high, just go ahead and treat!

Well....: I am an ENDOCRINOLOGIST, and you do have a pituitary Macro-Adenoma. The quality of your films on-line is not optimal. This is not a simple entity. You should be taken care of at a medical center with a great neurosurgeon, or at least a well trained endocrinologist. You need a series or laboratory tests... SOON!!
