Iranian Scientists Diagnose Cancer, Pathogenic Tissues with Radioactive Materials
The device is used to record and reveal the accumulation of radioactive materials in tissues. In this scanning method, based on the patient's condition, the radiopharmaceuticals are absorbed in different organs and a fraction of the photons pass through the surrounding soft tissue and are finally detected by the gamma camera.
“Our company operates in the field of nuclear medical equipment production and has succeeded in using advanced nuclear medicine technology to design and manufacture SPECT scanning device,” Behnoush Teymourian Fard, the deputy managing director of the knowledge-based company, told ANA.
“The device is capable of imaging the function of all tissues and organs of the body and can be used to diagnose different diseases, specially cancer,” she added.
Noting that radiopharmaceuticals emit gamma rays, Teymourian Fard explained, “In this non-invasive method, radiopharmaceuticals are injected into the patient’s body. Then, based on its specifications, the radiopharmaceutical accumulates more in one of the tissues of the body and emits gamma rays. Finally, the gamma rays which come out of patient's body are received and converted into two-dimensional and three-dimensional images; in this way, the physician can obtain a report on the functioning of certain organs of the body like the heart, kidney, liver, and even bones.”
She underlined that the device has no other domestic sample in Iran, adding that development of such a hi-tech technology in the world was monopolized by only a few advanced countries like the Netherlands, the US, and Germany so far.
While many imaging tests show what the internal organs look like, a SPECT scan can show how well the organs are working.
A SPECT scan can show how well blood is flowing to the heart; what areas of the brain are more active or less active; or what parts of the bone are affected by cancer.
