CT Scan Reports

How does the Radiologist distinguish between Healthy and diseased organ from the CT scans?

We are all uncertain as to how the Radiologist is able to tell the difference between a healthy and a diseased  structure or organs from the scan. Be assured that they are highly trained and they also work as a team.  If the scanning results are not clear, they will ask you to return and obtain more precise images,  or recommend another test to confirm. You may look at a few CT scanned images below which tell dramatic differences between healthy organ or organ  cross sections and disease states:

Image 1 is a CT scan of a section of the brain, showing the difference between normal or healthy (Left) individual  and an image obtained when he had suffered a stroke (right, red circle) due to cerebral (brain) arterial blood     vessel  blockage.

Image 2 is a contrast CT scan of brain cancer (red circle). The contrast made the tumor clear and more visible.

Image 3 shows a CT scan of infiltrating (invasive) cancer which has originated from elsewhere and has spread by invading into the colon. The contrast CT scan (Right) makes the cancer spot more clear and visible than the CT scan  alone.

Image 4 shows a contrast CT of different angles of a lower arm that had undergone fracture (broken bone).  It reveals the beauty of CT scan, being able to rotate and take images at different angles. At 90o angle of the  arm, only a minorfracture is observed, compared to the double and more pronounced bone fractures observed  with the arm at 180o angle.

How is CT scan different from MRI or PET?

CT, PET, and MRI scan tests are all diagnostic imaging techniques used to detect the presence of diseases  in the body, but they work differently; CT scan uses small doses of ionizing radiation called x-rays to obtain  images inside of your body as the scanner rotates and reveals if there is any abnormality of  the organs or structures.

MRI (Magnetic Resonance Imaging), on the other hand, utilizes magnetic field  and radio waves whichlineup with particles of the cells of the body to produce detailed images of the  structures and organs; whilewith PET(Positron Emission Tomography), an individual having the test is  injected with a   radiotracer  that has very smallradioactive sugar component and as the cells uptake     and metabolize  the tracer, radioactive energy is emitted which is used to generate images on a 3D computer.  Thus PET scan reveals if the tissues or organs of the  body are working properly by measuring its chemical  and biological processes.
