Pituitary Tumor Diagnosis | Tests for Pituitary Tumors Improving the lives of people with cancer is more urgent than ever. The optimal treatment of a prolactinoma depends on multiple factors, including: Sequential MR enhancement pattern in normal pituitary gland and in pituitary adenoma. It is very small in size (only about the size of a pea). Pituitary tumors form in the pituitary gland, a pea-sized organ in the center of the brain, just above the back of the nose. The volume of the pituitary gland is a better marker of pituitary activity. Index was outside the bounds of the array. 0, 30, 60, 90, 120 and 180 seconds), sequence: small FOV coronal and sagittal (same as T1 non-contrast), purpose: valuable to assess the cavernous sinuses and to characterize other sellar region tumors. Aside from evaluating the pituitary microadenomas, dynamic contrast MRI has an important role in assessing the macroadenomas (benign tumor). 4, Optic chiasm. Exam rooms and equipment are thoroughly disinfected after each patient, from mammography paddles to the CT & MRI bores, to the exam tables, counters, and areas of patient contact. This region consists of multiple nuclei that regulate temperature, water balance, sexual activity, and drinking behavior, Two active lobes make up the pituitary gland: anterior (adenohypophysis) and posterior (neurohypophysis). What is CPT code for MRI pituitary gland? MRI of the pituitary gland: T2-weighted coronal view. The pituitary gland volume changes depending on hormonal status and what would be a normal gland in one demographic would be grossly abnormal in another. A current creatinine (within 45 days) is needed on all patients over the age of 60, as well as patients that have high blood pressure, diabetes, acute vascular disease, or a history of kidney disease.

Most people with pituitary tumors never even know they have them. In MT imaging, the tissue contrast is quantified by the magnetization transfer ratio (MTR) and depends mainly on the macromolecules concentration. presence of prolapse of the suprasellar membrane (arachnoid): this occurs in front of the tumor (visible as a little cleft of CSF in front of the mass), presence of this space increases the likelihood of an intraoperative CSF leak, presence of invasion into the cavernous sinus/clivus/sphenoid sinus/orbit, location of normal pituitary tissue and infundibulum in relation to the mass, medially located or aberrant carotid arteries, aneurysms or other visible vascular anomalies especially in the cavernous sinuses, entering an artery transsphenoidally will not bode well for the patient, the surgeon or the radiologist, size of the bony sella, expanded or not, is useful, gives you an idea of the size of the surgical corridor, degree of pneumatization of the sphenoid, location of the sphenoid septum and any anomalous sinus anatomy, this is best assessed by CT but is visible also on post-contrast coronal T1 images, the location of sphenoid septum helps guide the transsphenoidal approach and ensures that the pituitary fossa is entered rather than adjacent cavernous sinus or orbit, bony dehiscence over the carotid arteries in the sphenoid (better seen on CT), presence of florid sinus disease, nasal polyps, septal spurs, etc. This knowledge helps doctors plan medical or surgical strategies.
