What does a 64 slice CT mean?

Washington Hospital’s Outpatient Imaging Center uses a state-of-the-art 64-slice computed tomography (CT) scanner. The Scanner creates 64 high-resolution anatomical images per rotation. This will decrease scan times to several seconds, less than 15 seconds in most cases.

What is the difference between 64 slice and 128 slice CT?

To reduce the radiation dose, it is important to use different methods with the scanner provided. Compared with 16-slice and 64-slice CT, 128-slice CT has more detectors, which means larger volume coverage and shorter scan times.

How much does a 64 slice CT scanner cost?

System users say 64-slice scanner costs a little more than $1 million, while a 256-slice scanner runs about $2 million, and a 320-slice system costs about $2.5 million. Diagnostic and Invasive Cardiology spoke with cardiac imaging specialists to gain their insights into this debate.

How many detectors are in a 64 slice CT scanner?

A floating or wobbling focal spot is used to create two slightly different beam projections on an array of detectors (32 x 0.6 mm central detectors flanked on both sides by 4 x 1.2 mm detectors) feeding 32 channels; the combination of two focal spots with 32 detectors results in a “64 slice” system.

Is 128 slice CT scan good?

128- Slice dual source CT angiography had an overall sensitivity of 95.26%, specificity of 95.12%, and positive predictive value of 88.46% and negative predictive value of 98.08% with invasive catheter angiography as the gold standard.

How does a 64 slice CT scan work?

The coronary vessels can be visualized and the presence of any blockage easily seen. The 64 slice CT scanner provides images of the heart in between each contraction, without causing any blurring of the images.

How much does a cardiac CT scan cost?

The presence of mechanical heart valves, pacemaker leads and any other foreign body around the heart can interfere with the quality of the image. Each scanner costs between $1.5 million to $2 million. It does have radiation exposure and may not be suitable for pregnant females.

Is the heart always beating on a CT scan?

The CT is an excellent technique to make a diagnosis of disorders in many different parts of the body, however, because the heart is constantly beating, CT scan could never be used to image it in the past.

What do you need to know about a heart scan?

Heart scan (coronary calcium scan) A heart scan, also known as a coronary calcium scan, is a specialized X-ray test that provides pictures of your heart that can help your doctor detect and measure calcium-containing plaque in the arteries. Plaque inside the arteries of your heart can grow and restrict blood flow to the muscles of the heart.
