What does a MIBG scan show?
An MIBG scintiscan is a type of imaging test. It uses a radioactive substance (called a tracer). A scanner finds or confirms the presence of pheochromocytoma and neuroblastoma. These are types of tumors that affect nerve tissue.
What is the best imaging for pheochromocytoma?
Computed tomography (CT) CT is the most common imaging method used in the diagnosis of pheochromocytomas. Compared to MRI, it is more widely available, less expensive, and offers better spatial resolution.
How long does MIBG scan take?
The test can last 1-2 hours, depending on your child’s height. The technologist or nurse will secure your child with soft, safety belts. The table will slowly move through a device called a scanner. An MIBG scan does not hurt.
Which is the most common surgical treatment option for a person with pheochromocytoma?
Surgical resection of the tumor is the treatment of choice for pheochromocytoma and usually results in cure of the hypertension.
How accurate is an MIBG scan?
The results of an MIBG scan are relatively reliable, with about 85% accuracy. If your healthcare provider suspects that you have a neuroendocrine tumor, they may order an MIBG scan. A special camera takes pictures inside your body after your provider injects a radioactive substance (tracer) into your bloodstream.
What does MIBG stand for?
MIBG stands for Meta-Iodo-Benzyl-Guanidine. The treatment uses a radioactive form of iodine called iodine 131. The radioactive iodine circulates through your body in the bloodstream. The neuroendocrine tumour (NET) cells pick up the radioactive iodine wherever they are in the body.
Can pheochromocytoma be misdiagnosed?
Conclusion The clinical appearance of pheochromocytoma is complicated and lacking in specificity, together with the tumor secretes a great deal of catecholamine which result in abnormality of blood glucose, blood lipid and abnormal hormone secretion, so pheochromocytoma is easily diagnosed mistakenly.
What does pheochromocytoma look like on CT scan?
Pheochromocytomas are usually solid when small but may appear as fatty, cystic, or calcified adrenal masses. They can be of sufficiently low attenuation at CT to be mistaken for an adenoma and may also mimic lipid-rich adenomas on unenhanced and washout studies.
How can I prepare for MIBG scan?
How do I prepare for an MIBG scan? Your healthcare provider will ask you to take a medication containing iodine (sometimes called Lugol’s solution) the day before the test. The medication helps protect your thyroid from the radioactive substance. You may need to take it for a couple of days afterward as well.
How is an MIBG scan done?
A radioisotope (MIBG, iodine-131-meta-iodobenzylguanidine) is injected into a vein. Later that day (or the next day) you lie on a table that is positioned under the arm of the scanner. The abdomen is scanned. You may be asked to return for repeated scans for 1 – 3 days.
How is pheochromocytoma surgery done?
Surgery to remove pheochromocytoma is usually an adrenalectomy (removal of one or both adrenal glands). During this surgery, the tissues and lymph nodes inside the abdomen will be checked and if the tumor has spread, these tissues may also be removed.
What are 4 possible treatments for pheochromocytoma?
Medications, such as alpha blockers, beta blockers and calcium channel blockers, keep smaller veins and arteries open and relaxed. This improves blood flow and decreases blood pressure. Some of these medications may also cause your heart to beat more slowly and with less force.
