This section focuses on SPECT (Single Photon Emission Computed Tomography) scans and its practice in nuclear medicine, for mapping brain and other internal organs, using radioactive isotopes.

The term Single Photon Emission Computed Tomography ( SPECT ) may not be new to medical professionals (Phew, so very long, no? Better we call it SPECT from here onwards), but for the neophytes, SPECT scans is just another kind of nuclear imaging that makes use of gamma rays, and demonstrates how the blood runs to organs and tissues within human body. Here we want you to understand that the tissues (healthy and unwell) react to radioactive isotopes/tracers differently that we will get to see more, as we continue reading further over the current page, and more. So, be patient enough along the journey! (Thank you)

SPECT scan puts together two different medical technologies (radioactive material, and computed tomography ) to analyze human (internal) body, and the radioactive tracer lets the Physician observe the blood flow inside the body, just we specified above.

Previous to going for SPECT scans the patient is instilled with a radioactive chemical that emits gamma rays, to be distinguished back by the scanner for effective diagnosis and treatment. Here, the attached computer processor brings together the information gave off by the gamma rays, emitting back, and transform it further to 2D (two-dimensional) cross-section (by making a slice through an object), and these cross-sections put in further to shape a 3-dimensional image of human brain, or other internal parts.

The radioactive chemicals (tracers) or radioisotopes that are being used in SPECT scans pass securely through human body and spotted back by the scanners, but the kind of radioactive chemicals/radioisotopes (tracers) used fluctuate (i.e. different radioactive chemicals are being used for analyzing different body disorders) extensively on what the Physician desires to gauge anything in the body for, as for the discovery of any malignant tumors the Physicians might make use of Fludeoxyglucose (18F)/FDG in medical imaging for to recognize metabolism of the tumor.

But usually the examination varies from a Positron Emission Tomography (well know as PET ), where the radioactive traces do not get dissolved by the enclosed tissues, but remain in the bloodstream, bounding images (through scanner) enclosing specific regions with bloodstream.

For the patients that are in doubt about cost of going through SPECT scans ( SPECT scans brain and other) would be reassured to know that it is inexpensive, and readily available than other higher resolution Positron Emission Tomography techniques.

Moreover, if you have been speculating about the effectiveness of a Single Photon Emission Computerized Tomography then do not remain puzzled any longer. Just to sidetrack, there are many SPECT companies and SPECT vendors available that you can (as a medical professional) seek assistance to know more about its features, if are in doubt about anything.

To bring you back further, SPECT scans allow for the effective analysis of functions of internal body organs that we discussed above, too, and through SPECT scan technique Physicians try to instill radioactive chemicals inside human body, and attempt to view the flow of blood from end to end along arteries, veins in the brain (you can even refer more on the following topic SPECT scan brain).

Going extra, some test analysis even show that SPECT scan is more responsive to brain damages, than other conventional forms of Magnetic Resonance Imaging ( MRI ) or Computed Tomography ( CT ) scan techniques. Besides, on the same note SPECT scans have been found very beneficial for evaluating medically unmanageable convulsions (any involuntary bodily movement/functional changes)

If you are cogitating about the following, then please remain acquainted that SPECT scans are useful in analyzing stress fractures in the spinal column, and other blood divested regions of human brain, following a sudden stroke, or inflicting out with malignant tumors, and very specifically qualified/skilled technologists (nuclear medicine) perform this test/scan ( SPECT ) in the hospital or other O/P medical imaging centers.

The nuclear imaging done through SPECT scans uses radioactive chemicals (tracers) as we discussed above in other section, along with a special digitized camera for to generate pictures/images of human organs, and this technique allows the Physicians diagnose the functionalities of the internal organs of the human body.

Unlike other mode of scanning (through X-rays) SPECT scans generate 3-dimensional images (3D) of internal organs, and let the Physicians/professionals know exactly about the functionalities of the organs. By effectively utilizing this technique ( SPECT scans) they can know how the blood flows towards heart, and furthermore be acquainted with other parts of the brain that are full of zip or either motionless.

To refresh you, Physicians have been found asking for SPECT scans to analyze varied medical conditions and diseases, viz. Cancer/Tumor, Brain disarray, or Coronary heart diseases (to name a few), and to your immense satisfaction and pleasure, SPECT scans have been found to be secured, mostly, as the patient is instilled only with a radioactive isotope/tracer (radioactive chemical), but there are cases where some bled profusely, and others had pain/swollen regions over the body on being injected by, but uncommonly any allergic responses have been noticed by with the usage of radioactive tracers.

And, it is for all the women heavy with child (colloquially) or is breast-feeding that want to go through SPECT scans, it is not advisable or secured for them, as chances are in abundance that the radioactive tracer/isotope may be transmitted to the rising fetus/baby, and women are counseled for pregnancy check-ups prior they go for SPECT scans, and related techniques.

We presume you had an enriching experience sailing through the section we had presented over, and anticipate for your favorable responses and comments to help us come more on it! Moreover, just surf along some more pages that we have for you on other core medical issues, without fail!
