Some protocols call for repeating the study at diff erent phases of contrast enhancement. Whenever possible, the repeat scans should be taken at the same location as the unenhanced images
Unlike a conventional x-ray—which uses a fixed x-ray tube—a CT scanner uses a motorized x-ray source that rotates around the circular opening of a donut-shaped structure called a gantry. During a CT scan, the patient lies on a bed that slowly moves through the gantry while the x-ray tube rotates around the patient, shooting narrow beams of x-rays through the body . If you're looking at bilateral organs, like your kidneys or the 2 lobes of the brain, compare the 2 sides to look for any abnormalities the prototype of the ﬁrst medical CT scanner and is considered the father of computed tomography. CT was introduced into clinical practice into 1971 with a scan of a cystic frontal lobe tumor on a patient at Atkinson Morley Hospital in Wimbledon (United Kingdom). After this, CT was immediately welcomed by the medical community an

Because of the great difference in beam attenuation ability between the dense bone of the skull and the much less dense tissue of the brain, streak artifacts are common. This inherent limitation may be managed by decreasing slice thickness when scanning the posterior fossa and increasing the kVp setting. BOX 19-2 Key C ncep

They can be used to: diagnose conditions - including damage to bones, injuries to internal organs, problems with blood flow, stroke , and cancer. guide further tests or treatments - for example, CT scans can help.
CT scans can also be used to guide a biopsy needle into a tumor. This is called a CT-guided needle biopsy. For this test, you stay on the CT scanning table while a radiologist moves a biopsy needle toward the tumor. CT scans are repeated until the tip of the needle is within the mass.

Advances in segmentation algorithms and increased availability of three-dimensional (3D) printers have made it possible to create cost-efficient patient-specific models without expert knowledge. We introduce a general workflow that can be used to convert. Examine the brain for: Symmetry - make sure sulci and gyri appear the same on both sides. (easiest when patient not rotated in the scanner) Grey-white differentiation - the earliest sign of a CVA on CT scan is the loss of the grey-white interface on CT scan. Compare side to side. Shift - the falx should be in the midline with ventricles the same on both sides Computed tomography is an imaging procedure that uses special x-ray equipment to create detailed pictures, or scans, of areas inside the body. It is sometimes called computerized tomography or computerized axial tomography (CAT).. The term tomography comes from the Greek words tomos (a cut, a slice, or a section) and graphein (to write or record). Each picture created during a CT procedure.
The CT scans were well tolerated by all patients and all could hold their breath during data acquisition. The mean (SD) scan duration was 15.4 (2.8) s (range 10.4-22.4). The average (SD) heart rate was 59 (6) bpm (range 44-69).

Scan and step is one mode of scanning.It was the first scanning mode developed and is still used today for some procedures.
