Computed Tomography, or CT, refers to computerized imaging procedures where an x-ray beam is aimed towards the patient and rotated around the body, in order to create cross-sectional images of the body. The word “tomography” is derived from Greek for, “tomos” meaning section or slice and “graphe” meaning drawing. In referring to CT scanners, the word “slice” is often mentioned, but does it refer to? 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. The first CT scanners offered single slice CT SSCT images but now there are multiple-slice CT scanners MSCT. The limitation with using a SSCT was that the thinner slices requiring high image-quality were not achievable unless the region to be scanned was very restricted, leading to low-quality images. A solution to this issue was to utilize the x-ray beam, incorporating multiple rows of detectors, thereby collecting more than one slice at a time and reducing the number of rotations needed. This method also led to the development of MSCT technology. The primary difference in the hardware between the two methods is the design of the detector arrays. SSCT detector arrays are one dimensional, consisting of high numbers of detector elements in a single row, whereas the MSCT allows for each individual element to be divided into several smaller detector elements creating a 2-dimensional array. As seen in the image, as opposed to a singular row of detectors along the fan beam, there are multiple rows of detectors. The first scanner with more than one row of detectors was introduced by Elscint in 1992 and was called the CT-Twin. This scanner allowed data for 2 slices to be shown simultaneously; this addressed x-ray heating problems, and significantly reduced scanning time. Eventually, the first “modern” versions of MSCT scanners were developed and introduced in 1998 and simultaneously acquired 4 slices, which meant four detector rows corresponding to four data channels. In 2002, the first MSCT scanners providing16 slices were introduced. In the current market, the commonly available CT slice counts include 16, 32, 40, 64, and 128 slices, with less common ones providing up to 256 and 320 slice CT scanners. The 4 to 8 slice scanners are slowly being withdrawn from the market. When patients are put through the CT, the circular opening rotates to take a series of x-rays with each rotation taking approximately 1 second. Multiple slice CT scanners initially could take four separate images through each rotation, but technology has improved to the level that CT scanners can now take between 6 to 128 separate images in a singular rotation, meaning that it takes significantly less time to complete a CT scan. Different slice-counts for CT scans can be useful for many different scenarios. The majority of CT scanners can perform general imaging procedures, to include chest and head exams as well as multiple different body views to scan for any fractures. However, for cardiac procedures, higher slice counts are required to ensure optimum image quality. Multi-slice CT scanners have numerous advantages such as superior image quality and this can enable earlier diagnostic results. This essentially leads to shortening the diagnostic time for the patient, enhancing the treatment, and improving the patients’ long-term outcome. Radiation dosage is always a major concern when getting a CT scan, and with the higher slice CT systems, there is the additional benefit of reducing this dose. With technologies such as automatic exposure control AEC and iterative reconstruction IR, a patient scanned on a higher slice CT will receive significantly lower doses of radiation than a patient on a lower dose CT scanner. MSCT can improve overall patient experience as well. CT scanning is an inherently unsettling experience and now with the ability to capture images faster with multiple slice scanners, patients are able to spend less time on the table, and the scanner puts the images into physicians’ hands faster. MSCT also allows large anatomic body ranges to be scanned producing thin and thick sleeves; thick slices are important for primary interpretation, and thin slices are important for reducing partial-volume streaks and allowing for high quality 3-dimensional reconstructions. In summary, the higher the slice count, the faster the speed of the scan; a conventional single-slice CT scanner may take up to ten minutes to complete a scan whereas multi-slice scanners are able to do the job within seconds. Shortening the time for scanning is especially useful for the treatment of children or others who may find it difficult to lie in one position for an extended period of time. 16-slice CT scanners are the ideal machines for higher-use facilities and for everyday use, particularly where reducing scan time is important. It is a good fit for Urgent Care Centers and hospitals alike. However, 32 and 64 slice CT scanners are becoming standard for imaging centers and hospitals; the accuracy and speed make them very suitable for hospitals with higher patient throughput. These higher slice CT scanners provide longer coverage per gantry rotation than the 16 slice scanners and reduce the likelihood of motion artifacts, which can cause blurring or double images in scans. The BodyTom Elite from Neurologica, a subsidiary of Samsung Electronics, is the world’s first mobile, full-body, 32-slice CT scanner, which incorporates the higher CT slice count as well as the portable aspect which allows for transporting the machine right to the patient’s bedsides for any procedures, as opposed to the traditional method of transporting patients to the radiology room. With the two combined, systems like this can save facilities valuable time and money. In conclusion, there are many advantages to the multiple slice CT scanners over the single slice scanners; these machines can increase the diagnostic capabilities of the scan, resulting in clearer images for the medical professionals, a diminished exposure of radiation for the patients, and better long-term outcomes. Multiple slice CT scanners will continue to evolve and grow as they have become a primary diagnostic imaging tool.
Acomputerized tomography (CT) scan combines a series of X-ray images taken from different angles around your body and uses computer processing to create cross-sectional images (slices) of the bones, blood vessels, and soft tissues inside your body.

Many people tend to compare CT scanners and MRI scanners against each other. After all, they’re both quite similar machines used to take slices of pictures of our internal organs. However, there are some differences between the two machines that make each more suitable for different uses. For instance, CT scanners are far better at imaging blood vessels and bones, whereas MRI scanners are used to identify changes in soft tissue, tendons, the brain, and more. That being said, these main differences aren’t enough to pick the right choice. Within the same category of machines, there are still different types of scanners to choose from! For instance, there are different slices for CT scanners, some in four to eight, others up to 128—and even higher. For the purpose of this article, we will be focusing on the CT scanners and their slices to help you understand which CT scanner is the best fit for your need 4 & 8-Slice For the most basic of CT scanners, you will usually be faced with a 4- or 8-slice scanner. Though the number may seem incredibly small compared to other CT scanners, these are still excellent for clinics with only a few patients who need a scan. Plus, these are the cheapest types of scanners you will find in the market—so any health service with a limited budget can generally afford one! In other words, this affordable scanner will be the scanner of choice if time is not a factor in your diagnosis or procedures. 16-Slice As an excellent choice for price-performance, many health facilities will opt for the 16-slice CT scanner. It is the go-to for clinics or departments that experience a steady amount of patients that need scanning faster than what an 8-slice scanner can provide. In short, the 16-slice scanner offers excellent reliability and good enough speed that even urgent care centers will still use them. 32 & 40-Slice Going a little higher into the slice count, these 32 and 40-slice scanners are typically treated similarly to their 16-slice counterparts. The only difference here is that they are even faster and offer much more coverage per gantry rotation—meaning that the risk of motion artifacts is reduced. You will be investing in this type of scanner if you need something better than a 16-slice scanner with a price jump that isn’t too high. 64-Slice 64-slice scanners are the usual scanners you will find in extensive health facilities, like hospitals and imaging centers. Because of its much higher slice count, not only is scan time reduced significantly, but it can also facilitate advanced studies thanks to the accuracy. Note that cardiology still requires the slowing of the heartbeat rate despite the machine’s speed and accuracy. However, it is still an excellent machine for closer cardiac research. 128-Slice and higher These 128-slice or higher CT scanners are the top-of-the-line CT scanners you will find. Up to 320 slices, these machines can provide a full-body scan in mere seconds. Thanks to its incredible speed and accuracy, specialty practices generally invest in these costly machines. If you are running a simple clinic, there isn’t a way to justify an investment in this kind of CT scanner, unless you are a specialty practice or experience an abnormally high patient rate that requires scanning each day. Conclusion With all of that information in your hands, it is up to you to pick a suitable CT scanner for your practice. If you are looking for something that you can use in a small clinical setting with a limited number of patients, a 4, 8, or even 16-slice scanner will do perfectly. On the other hand, if you have a large volume of patients, a 34 or higher can meet your needs. Then again, if you are a specialty clinic, you may find the need for 128 or higher slice CT scanners. In other words, carefully consider your needs and compare them against the CT scanners to see if they will work!
