    What is 16-slice CT scan?

    The 16-Slice CT Scanner captures multiple images of a patient's anatomy in a matter of seconds and presents information 3-dimensionally. This means the images of the body are now taken much faster, therefore reducing the examination time and increasing your comfort.

    How much does a CT machine cost?

    For example, the cost of a CT scanner can be as low as $65,000 for a refurbished one that produces only small images quickly. A larger and brand new CT scanner can run as high as $2.5 million. Prices are slightly higher for MRI machines, running up to about $3 million for a new machine.

    How long does a CT machine last?

    According to Asset Management in Radiology, a 2009 publication of the AHRA, CT scanners should ideally be replaced every eight years.

    Are some CT machines better than others?

    An analysis of data on 107 patients undergoing heart scans found that radiation exposure was reduced by as much as 95 percent compared to the range of current machines, while the resulting images showed less blurriness, reduced graininess, and greater visibility of fine details.

    Which CT scanner has least radiation?

    Low-dose CT scanners used for screening procedures require significantly less radiation than a standard CT scanner. The low-dose Siemens SOMATOM go. ALL CT scanner at Preventative Diagnostic Center in Las Vegas uses the least amount of radiation possible to create the highest quality images in a matter of minutes.

    What does slice mean in CT?

    The term slice refers to the number of rows of detectors in the z-axis of a CT. For example, in an 8-slice CT, there are eight slices of data captured for each rotation of the gantry.

FOX6's Julie Colins gets an inside look the GE manufacturing facility in Waukesha where these advanced products are made.

    What is CT technology?

    Computed tomography is commonly referred to as a CT scan. A CT scan is a diagnostic imaging procedure that uses a combination of X-rays and computer technology to produce images of the inside of the body. It shows detailed images of any part of the body, including the bones, muscles, fat, organs and blood vessels.

    How do you do a CAT scan?

    During a CT scan, you lie in a tunnel-like machine while the inside of the machine rotates and takes a series of X-rays from different angles. These pictures are then sent to a computer, where they're combined to create images of slices, or cross-sections, of the body.

    Which is better CECT or HRCT?

    In conclusion, there is improved diagnostic accuracy and confidence for diagnosis and exclusion of bronchiectasis using 16-slice chest CT (1 mm cuts) compared with conventional HRCT of the chest. Bronchiectasis is a chronic disabling lung disease affecting between 1 in 1000 and 1 in 5000 of the general population.

    Is HRCT thorax harmful?

    Do CT scans damage eggs?

    We know that very high radiation doses can damage or kill eggs or sperm. However, diagnostic radiology (e.g., x-ray or CT) uses only low radiation doses. These doses are much lower than those that could produce destructive effects to eggs or sperm.

    Dual energy CT, also known as spectral CT, is a computed tomography technique that uses two separate x-ray photon energy spectra, allowing the interrogation of materials that have different attenuation properties at different energies.

    How physics is used in CT scan?

    In the particular case of the CT, the emitter of x-rays rotates around the patient and the detector, placed in diametrically opposite side, picks up the image of a body section (beam and detector move in synchrony). Unlike x-ray radiography, the detectors of the CT scanner do not produce an image.

    What is a spectral CT scanner?

    What is spectral CT? Spectral CT is a way to visualize tissue composition with CT. We can determine the atomic number of the tissues in the body; and if patient has received iodinated contrast, spectral CT can determine the amount of iodine in the tissues, and virtually subtract the iodine.
