Gadodiamide 0. Dynamic coronal images were obtained simultaneously from three different portions of the gland. Fifteen images were obtained from each of the three portions at an interval of twenty to thirty seconds between the images. Result : Dynamic MRI was performed in nineteen patients with microadenoma and six cases of macroadenoma.

Dynamic study did not add to the diagnosis and was merely of confirmatory value in remaining eight patients. Dynamic MRI study was used to identify the optimal time for delineation of the adenomatous tumor, by virtue view of the simultaneous differential contrast enhancement patterns between normal pituitary gland and adenoma. Further the enhancement pattern of the normal pituitary gland, the adenomatous nodule and the optimal delineation were individually assessed. This evaluation revealed the average time in seconds for onset of enhancement and the peak enhancement of normal pituitary gland were In comparison the pituitary adenomatous nodules exhibited an average time of The average time in seconds for optimal tumor delineation was Conclusion : Dynamic MR Imaging has emerged as a technically refined tool in the evaluation of pituitary adenomas.

The key questions in evaluation of pituitary adenomas include the presence or absence of a tumor, the number, the location of adenoma nodule, the invasive effects on adjacent structures and the post therapy status of adenoma. Clearly, dynamic MR Imaging is the foremost imaging modality answering these vital questions in patients with pituitary adenomas.

Second Opinion for Pituitary Tumor

Neuroradiology ; This might be an option if your tumor isn't causing signs or symptoms. Many people with pituitary tumors function normally without treatment if the tumor isn't causing other problems. If you're younger, watchful waiting can be an option as long as you accept the possibility of your tumor changing or growing during the observation period, possibly requiring treatment. You and your doctor can weigh the risk of symptoms developing versus treatment.

Explore Mayo Clinic studies testing new treatments, interventions and tests as a means to prevent, detect, treat or manage this disease. It's natural for you and your family to have questions throughout the diagnosis and treatment of a pituitary tumor. The process can be overwhelming — and frightening. That's why it's important to learn as much as you can about your condition. The more you and your family know and understand about each aspect of your care, the better.

You might also find it helpful to share your feelings with others in similar situations. Check to see if support groups for people with pituitary tumors and their families are available in your area. Hospitals often sponsor these groups. Your medical team also may be able to help you find the emotional support you might need.

You're likely to start by seeing your primary care provider. If your doctor finds evidence of a pituitary tumor, he or she might recommend you see several specialists, such as a brain surgeon neurosurgeon or a doctor who specializes in disorders of the endocrine system endocrinologist. When you make the appointment, ask if there's anything you need to do in advance, such as fasting before having a specific test.

Diagnosis Pituitary tumors often go undiagnosed because their symptoms resemble those of other conditions. Endoscopic transnasal transsphenoidal surgery In transnasal transsphenoidal endoscopic surgery, a surgical instrument is placed through the nostril and alongside the nasal septum to access a pituitary tumor.
