What is the difference between mbi and bsgi

Since mitochondria play an essential role in cancer metabolism, it is known that Tc99m-Sestamibi will accumulate to a greater extent in cancerous cells than in normal cells. MBI is based on an improved imaging system developed specifically for breast imaging.

During the imaging exam, the breast is placed between two gamma camera heads engineered with cadmium zinc telluride CZT solid-state pixilated detectors. Therefore, the MBI system is superior to BSGI in detecting small less than 1 cm breast cancers and allows imaging to be performed with lower injected doses of Tc99m-Sestamibi. The MBI system has two heads and applies only mild compression to immobilize the breast.

Similar to mammography, MBI provides craniocaudal and mediolateral oblique views of each breast, which facilitates comparison between MBI images and mammographic images. A - Right screening mammogram CC and MLO images showed dense fibroglandular breast tissue and was interpreted as a negative mammogram. B - MBI showed a 3 cm mass with marked uptake of the radiotracer in the right breast arrows and normal distribution of the radiotracer in the left breast.

C, D - Breast MRI sagittal and axial views after administration of intravenous contrast showed abnormal enhancing 3 cm mass in the right breast arrows , corresponding to the mass seen with MBI.

Left panel images A, B demonstrates detection of invasive ductal carcinoma in a mammographically dense breast by BSGI that is obscured on mammography. Right panel images C, D demonstrates detection of invasive ductal carcinoma in a mammographically nondense breast by both mammography and BSGI.

Worldwide, background radiation doses range from 2. J Am Coll Radiol. Nearly half of all women have dense breast tissue. The sensitivity of mammography is known to be reduced in women with dense breast tissue.
