The pituitary gland is a small gland that controls the body’s hormones(1). A pituitary MRI or magnetic resonance imaging is a technique that takes pictures of the brain’s pituitary gland and its surrounding areas.
A systematic approach to the pituitary region is crucial as pituitary lesions may significantly alter a patient’s quality of life.
MRI is the modality of choice for hypothalamic-pituitary-related endocrine diseases(2). This modality uses a magnetic field, radio waves, and computer program to generate detailed image slices (cross-sections) of the head(3).
Soft tissue images allow the radiologist to evaluate and distinguish normal, healthy tissues from damaged ones.
Anatomy of the Pituitary Gland
It is essential to clearly understand the pituitary gland anatomy and its surrounding structures for a successful assessment and interpretation of MR images.
The pituitary gland is located in the sella turcica of the sphenoid bone. This gland is anatomically and functionally related to the hypothalamus(4).
The hypothalamus is a brain region that extends from the anterior commissure to the posterior commissure. This region consists of multiple nuclei that regulate temperature, water balance, sexual activity, and drinking behavior(5).
Two active lobes make up the pituitary gland: anterior (adenohypophysis) and posterior (neurohypophysis)(6).
The anterior lobe produces and secretes most pituitary hormones. Meanwhile, the posterior lobe releases two hormones initially produced in the hypothalamus’ nuclei.
On T1-weighted and T-2 weighted MR images, the anterior lobe is isointense (abnormality is similar to a reference structure) to the cortical brain. Meanwhile, the posterior lobe appears as a bright spot on T-1 weighted images(7).
Pituitary MR Imaging Techniques
MRI is the modality of choice for pituitary gland-related pathologies due to its superior soft-tissue contrast, lack of ionizing radiation, and multiplanar capability(8).
Additionally, MRI provides valuable information about the relationship of the gland with adjacent anatomical structures(9). This knowledge helps doctors plan medical or surgical strategies.
MR imaging aims to obtain a high spatial resolution image with a reasonable signal-to-noise ratio. It is important to have an accurate diagnostic differentiation of these lesions for effective and safe disease management(10).
Various advanced MR imaging techniques help evaluate and diagnose pituitary gland-related conditions.
Dynamic Contrast-Enhanced MRI
Dynamic contrast MRI proves to be the best imaging tool in evaluating pituitary adenomas(11). A fast turbo spin-echo sequence (TSE) or a three-dimensional transformation gradient-echo may be used for a more dynamic study.
This MRI technique usually requires a contrast medium of intravenous gadolinium (chemical-based dye) to improve the images’ clarity(12).
After a bolus injection of gadolinium, six consecutive sets of three images are obtained in the coronal (frontal) plane every ten seconds(13).
Aside from evaluating the pituitary microadenomas, dynamic contrast MRI has an important role in assessing the macroadenomas (benign tumor). This technique differentiates residual or recurrent tumors from postoperative tissues(14).
MR imaging can differentiate lymphocytic hypophysitis (LH) from nonsecreting macroadenomas. MR features indicative of LH include(15):
- Symmetric enlargement of the gland
- Homogeneous appearance
- Intense contrast enhancement
- Thickening and enhancement of the pituitary stalk
- Loss of posterior pituitary bright spot
- Enhancement of dura adjacent to the pituitary mass
- Intact sellar floor
3-Tesla (3T) MRI
3-Tesla MRI with stronger magnetic field strength offers an improved image quality. This technique also has enhanced spatial resolution with subtle differences between normal and abnormal tissue(16).
According to a recent study, preoperative localization of pituitary microadenomas in Cushing’s disease (hormonal disorder) is relatively better with 3T MRI(17).
The knowledge of average pituitary gland volume and pituitary stalk’s imaging appearance is vital in diagnosing different lesions.
3T MRI provides an accurate assessment of the pituitary stalk and subtle gland volume changes(18).
Magnetization Transfer (MT)
Magnetization transfer (MT) imaging is a recent advancement in the imaging field. This technique is useful for preoperative and postoperative assessment of pituitary adenomas in hyperprolactinemia patients(19).
In MT imaging, the tissue contrast is quantified by the magnetization transfer ratio (MTR) and depends mainly on the macromolecules’ concentration. Increased MTR values highly suggest persistent adenomatous tissue(20).
Radiologists can also use the MT technique in postoperative assessment and follow-up of patients with pituitary adenomas, especially when classical MRI is negative for residual tumor(21).
MT imaging’s prospect includes other pituitary disorders, such as precocious puberty and pituitary insufficiency(22).
Diffusion-Weighted Imaging (DWI)
Researchers have evaluated the role of diffusion-weighted imaging in the early detection of acute pituitary apoplexy. This condition results from either the hemorrhage or infarction of the pituitary gland(23).
A study noted that DWI assists in the early diagnosis of acute pituitary apoplexy with timely intervention and excellent outcomes(24).
Pituitary apoplexy may be diagnosed by the presence of peripheral contrast enhancement of an intrasellar mass and restricted water diffusion within the lesions on diffusion-weighted images(25).
Moreover, acute pituitary apoplexy on DWI may mimic pituitary hemorrhage, abscess, and hypophysitis(26).

How would your body be affected if your pituitary gland was not working properly? ›In women, the deficiency decreases egg and estrogen production from the ovaries. In men, the deficiency decreases sperm and testosterone production from the testicles. Women and men may experience a lower sex drive, infertility or fatigue. In children and adolescents, delayed puberty is usually the only symptom.
What doctor treats pituitary gland? ›
Your Own Team of Pituitary Specialists
Endocrinologists. Neurosurgeons. ENTs. Neuro-ophthalmologists.
It has been documented that clinical depression and anxiety are common with pituitary disorders. Some patients report memory and mental confusion, anger and/or rage and even changes in a patient's overall sense and awareness of themselves.
What are the behavior changes of pituitary tumor? ›The pituitary gland dysfunction and hormonal imbalances caused by a problematic tumor can also trigger erratic mood swings, bouts of uncharacteristic anger or rage, easy irritability, and loss of emotional control.
Can bloodwork detect pituitary tumor? ›Hormone Blood Testing to Diagnose Pituitary Tumors
The first step in diagnosing a pituitary tumor is often a blood test to check for hormone imbalances. Because the pituitary gland plays an important role in hormone production, the presence of a tumor can lead to an imbalance of certain hormones in the body.
If the tumor is very large it may press on other parts of the brain and cause problems with memory, weakness, or numbness. Some pituitary tumors may be observed without treatment because they may grow very slowly.

Is pituitary tumor removal a major surgery? ›The main treatment for most pituitary tumor patients is a minimally invasive operation called transsphenoidal surgery.
What percentage of pituitary tumors require surgery? ›In over 90% of patients, medical therapy (pills) reduces tumor size and blood prolactin levels. In approximately 8-10% of patients, medical treatment is not adequately effective and surgery, and possibly radiation therapy, may be necessary.
Is pituitary tumor considered brain surgery? ›Yes, pituitary surgery is considered brain surgery. However, rather than opening the skull in a traditional craniotomy, a neurosurgeon usually reaches a pituitary tumor through the nasal passages and the sphenoid sinus.
What are the chances of a pituitary tumor being cancerous? ›
However, in some rare cases, pituitary tumors can act more aggressively to recur or every exceedingly rarely be cancerous (malignant) and spread to other parts of the body. Pituitary cancer is rare, accounting for less than 1% of all pituitary tumors.
How does a pituitary tumor make you feel? ›Symptoms from tumor pressure
Macroadenomas can put pressure on the pituitary gland, on nerves, on the brain and on other parts of the body nearby. That can cause symptoms such as: Headache. Eye problems due to pressure on the optic nerve, especially loss of side vision, also called peripheral vision, and double vision.
According to US statistics, the 5-year relative survival is 64%. This means that, on average, people diagnosed with pituitary gland cancer are 64% as likely to live at least 5 years after their diagnosis as people in the general population. The 10-year US relative survival is 42%.

How fast do pituitary tumors grow? ›Most pituitary tumors are slow growing, approximately 1-3mm/year.
Can a pituitary tumor cause ear problems? ›Patients often wonder if pituitary tumors can cause ear or sinus problems. It is possible, but very rare, for a pituitary tumor to cause these symptoms.
What disorders are associated with the pituitary gland? ›The pituitary gland, sometimes called the “master gland,” produces hormones that enable other glands in the body to function. Pituitary gland disorders include acromegaly, Cushing's syndrome, diabetes insipidus, empty sella syndrome, hypopituitarism and pituitary tumors.
Does an MRI always show a pituitary tumor? ›They can show macroadenomas of the pituitary gland, as well as most microadenomas. MRI might not detect very small microadenomas, although many of these can now be seen with newer MRI machines, which have stronger magnets and can show even more detail.
Which diagnostic test is done to determine a suspected pituitary tumor? ›MRI is better than a computed tomography scan, which is described below, to diagnose most pituitary gland tumors. As a result, MRI is now the standard diagnostic test. Computed tomography (CT or CAT) scan. A CT scan takes pictures of the inside of the body using x-rays taken from different angles.
What are the markers for pituitary Tumour? ›What Do Pituitary Tumor Diagnostic Blood Tests Look For? To diagnose functional pituitary adenomas, doctors may run blood tests or other diagnostic tests to look for abnormally high amounts of: adrenocortisol (ACTH) and cortisol. growth hormone (GH) and insulin-like growth factor 1 (IGF-1)
Is pituitary tumors cancerous? ›
Pituitary gland tumors arising from the anterior pituitary gland are usually benign. Rarely, pituitary tumors may metastasize and are then termed pituitary carcinoma. Pituitary cancer includes pituitary carcinoma and systemic metastases to the pituitary gland.
How do doctors know if a pituitary tumor is cancerous? ›Most pituitary tumors are benign. Symptoms vary depending on the type of tumor and the affected area of the pituitary gland. Your health care provider may order blood and urine tests, CT scan, MRI, or biopsy to diagnose the tumor. Treatment may include surgery, radiation therapy, or medication.
What happens if you have a tumor on your pituitary gland? ›Pituitary tumors that make growth hormone also are called growth hormone-secreting tumors or somatotroph adenomas.
