Technetium (99m Tc) sestamibi is a lipophilic cation which, when injected intravenously into a patient, distributes in the myocardium proportionally to the myocardial blood flow. Single photon emission computed tomography imaging of the heart is performed using a gamma camera to detect the gamma rays emitted by the technetium-99m as it decays.

Tc) sestamibi are injected and a second acquisition of images is acquired 10 minutes later. For the 99mdual phase technique is used, 400 to 700 MBq of technetium ( Tc) sestamibi are injected and the first neck and mediastinum image is obtained 10 minutes later.

Technetium Tc 99m Sestamibi uptake was scored as: normal (no uptake), equivocal, low, moderate, or high uptake. The results of Technetium Tc 99m Sestamibi images and mammography were analyzed in comparison to histopathologic findings of malignant or non-malignant disease.

Chụp cắt lớp vi tính phát xạ đơn ( SPECT ) của tim được thực hiện bằng máy ảnh gamma để phát hiện các tia gamma phát ra từ Technetium-99m khi nó phân rã . For the 1-day protocol studies, a cross-talk correction was applied as follows. Count measurements from the lesion and background ROIs from the 99m Tc sestamibi images were decay corrected for the time interval between the 99m Tc maraciclatide and 99m Tc sestamibi acquisitions and reduced further by a factor of 0.94 (to adjust for biological washout of the 99m Tc sestamibi from breast tissue) [].

Specifically, brain, breast, thyroid, parathyroid, lung, and kidney tumors have been imaged. The Verner Morrison syndrome, which is caused by excessive vasoactive intestinal peptide (VIP), consists of watery di … Objective: To determine the frequency of the types of parathyroid gland hyperplasia and the sensitivity of sestamibi-(99m)Tc (MIBI) scintigraphy and ultrasonography (US) of patients with secondary hyperparathyroidism (SHPT) due to chronic renal failure.

The drug is a coordination complex consisting of the radioisotope technetium-99m bound to six methoxyisobutylisonitrile (MIBI) ligands, hence the name sesta (6) MIBI..

It is used to image blood flow to the heart muscle, esp. when combined with exercise or pharmacological “stress” tests. In a heart with normal blood flow, the isotope should be taken up uniformly throughout the heart muscle.

Early in the use of sestamibi scanning, a decision was made to reduce the dose of 99m Tc from 740 MBq to 370 MBq; this technical point needs to be reevaluated, since there are data to indicate improved imaging success with higher doses. 23 We are currently analyzing the details of our sestamibi localization procedures in an attempt to improve sensitivity for parathyroid localization.
