Čo je mibg scan

Multiple clinical and imaging tests are needed for accurate patient assessment. Iodine 123 (123 I) metaiodobenzylguanidine (MIBG) is the first-line functional imaging agent used in neuroblastoma imaging. MIBG uptake is seen in 90% of neuroblastomas, identifying both the primary tumor and sites of metastatic disease.

An MIBG scan may also be called MIBG scintigraphy or MIBG scintiscan. Why an MIBG scan is 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. MIBG scans are helpful for locating both bone and soft tissue tumors.

The MIBG scan has a sensitivity and specificity of 90% to 99%, and MIBG avidity is equally distributed between primary and metastatic sites. Although iodine I 123 (123I) has a shorter half-life, it is preferred over 131I because of its lower radiation dose, better quality images, reduced thyroid toxicity, and lower cost.

What is an MIBG scan?

An MIBG scan is a scan to look for:

neuroblastoma, a tumour in the adrenal glands, neck, chest or spinal cord

Jan 01, 2000 · We report a case of a 17-cm cortisol-secreting adrenocortical carcinoma in which [ 123 I]metaiodobenzylguanidine (MIBG) scan showed accumulation of the isotope in the area of the tumor. Catecholamine levels were normal, and no chromaffin cells were found in histological examination of the tumor. Hence, MIBG may be better at detecting DLB in patients with parkinsonism.29 A comparison in just DLB and AD subjects found DAT scans to be slightly more accurate, sensitivity and specificity 72% and 94% for MIBG, and 88% and 89% for DAT scans.30 In a comparison with brain perfusion SPECT in DLB subjects alone, sensitivity was the same for both Pokud je vaše tiskárna vybavena podavačem dokumentů, můžete skenovat dokumenty dopisního formátu nebo A4 po změně nastavení Velikosti stránky v aplikaci HP Scan.
