MRI PITUITARY /SELLA

MRI Pituitary / Sella Overview

Magnetic Resonance Imaging (MRI) of the pituitary gland and Sella turcica is a non-invasive imaging test that evaluates the anatomy and physiology of the pituitary gland situated at the base of the brain in the Sella turcica. It provides exquisite details of the region to identify tumours, cysts, and hormonal changes among other disorders. 

What is MRI of Pituitary / Sella? 

MRI of Pituitary and Sella is a high-level piece of imaging work meant to scrutinize the pituitary gland and its struts. It is especially good in the diagnosis of tumefaction, organo-structural changes of tissue, and any other features related to the hormonal function. 

Types of MRI Pituitary / Sella 

• Standard MRI: Gives high quality imaging of the pituitary gland 
• Contrast Enhanced MRI: Better analysis of tumours along with their vascular structures using gadolinium contrast 
• Dynamic Contrast MRI: Uses real time vision of microadenomas during contrast uptake 

List of Parameters Considered During MRI Pituitary / Sella

• The contours of the pituitary gland 
• Presence of tumours, cysts, or other structural irregularities 
• Optic chiasm pinch 
• Involvement of blood vessels or bleeding 
• Sella turcica shape 

Reasons for Taking an MRI Pituitary / Sella

Proposed diagnosis of pituitary adenoma or tumour 

• Hormonal imbalance of unknown origin 
• Disruptive vision phenomenon related to optic nerve restraints, tumour growth or other causes 
• Unexplainable shifting of bones (like excessive growth) (gigantism, acromegaly, dwarfism) 
• Remnants of surgery or radiation therapy 

When and Who Needs an MRI Pituitary / Sella? 

Indications: 

• Abnormal hormonal secretion (e.g. excessive secretion or less than required)  
• Possible development of pituitary tumours or adenomas  
• Optic chiasm compression related vision problems  
• Signs and symptoms of pituitary apoplexy (haemorrhage or infarction in the gland)  
• Headaches that are recurrent lasting for long periods with no clear underlying reason  
• Abnormal growth changes or abnormal puberty changes of unknown origin 

Patient Demographics: 

• Middle aged and elderly people who show signs of pituitary gland anomaly  
• Patients with likely suspicion of endocrine system anomalies  
• Patients with unknown reasons for vision related issues and those enduring long-term headaches  
• Patients being investigated for infertility 

Benefits of Taking the Test

• Non-invasive imaging with no radiation 
• Provides an accurate diagnosis with high precision soft tissue contrast. 
• Vital for managing endocrine disorders 
• Uncovers minute lesions that other imaging techniques fail to visualize 

Illnesses Diagnosed with MRI Pituitary / Sella

• Micro- and Macro-adenomas of pituitary glands 
• Supratentorial craniopharyngioma 
• Cysts of the pituitary gland 
• Empty Sella syndrome 
• Apoplexy of the pituitary 
• Disorders of puberty and adolescence (Cushing syndrome, acromegaly, prolactinoma) 

Preparing for MRI Pituitary / Sella

• Dress in comfortable loose clothes 
• All metallic contacts and devices must be removed, as these are considered dangerous gadgets 
• Inform the operator about their implants, pregnant patients, or other relevant medical conditions 
• If contrast is used, fasting may be necessary 

Pre-requisites 

• No allergies to contrast media (in cases where a contrast-enhanced MRI is needed) 
• Claustrophobic pre-medication if needed 

Best Time to Take the MRI Pituitary / Sella 

• After the designated physician's consultation  
• Pre-booked to minimize waiting periods and guarantee access 

Eligibility 

• Designated as low risk for most patients except for those who have unremovable metallic devices or pacemakers 

Procedure for Taking an MRI Pituitary / Sella 

• The subject reclines on the MRI couch laterally  
• A head coil may be put on for optimal imaging  
• Images are taken with the aid of magnetic fields and radio wave with the help of computer aided tomography or MRI equipment  
• Completion time is about half to three-quarters of an hour  
• Enhancement imaging procedures may be performed by contrast injection if there is a need 

Caution Before Taking the Test 

• An urgent appointment must be made to the X ray doctor if there are safety implants or is a possibility of maternity  
• Image clarity is contingent upon the patient remaining motionless throughout the procedure
