Is orbital CT scan and CT scan sinus the same?

Is orbital CT scan and CT scan sinus the same?

Not quite: The CT of the sinuses focuses in on the sinuses (though the radiation goes through the entire skull) and generally covers the entire set of sinuses (sphenoid, maxillary, frontal, ethmoid). The orbital CT will cover the eye sockets (and those pictures are zoomed in). While the sinuses lies behind the eyes (& so they overlap), the focus & coverage of these scans are slightly different. ...Read more

Ct scan, mri, nuclear medicine imaging, ivp scan, how are they different?

Ct scan, mri, nuclear medicine imaging, ivp scan, how are they different?

Quite different: Ct involves xray type radiation with cross sectional imaging in transaxial, sagittal, and coronal projections. Nuclear medicine, internal irradiation either injected intravenously, inhaled, ingested, injected subcutaneously.Ivp uses injection of contrast material for visualization of kidneys and bladder with x-ray. Mr imaging uses no ionizing radiation magnetic fields to generate x-sectional images. ...Read more

Computed Tomography (Definition)

Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! the image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more
