Types of Calcium Scans
There are three main types of calcium scans: Electron Beam Computed Tomography (EBCT), Multislice Computed Tomography (MSCT), and Magnetic Resonance Imaging (MRI).
-
Electron Beam Computed Tomography (EBCT)
EBCT is a non-invasive imaging technique that uses an electron beam to produce high-speed images of the coronary arteries. This technique is quick, taking only a few seconds to produce images, and uses a small dose of radiation.
EBCT is widely used in cardiology to assess the risk of heart disease by measuring the amount of calcium in the coronary arteries. The scan results are often expressed as an Agatston score, which indicates the severity of calcium buildup in the arteries.
-
Multislice Computed Tomography (MSCT)
MSCT is a more advanced imaging technique than EBCT that uses multiple rows of detectors to produce high-resolution images of the coronary arteries. This technique is faster than EBCT and produces more detailed images.
MSCT is widely used in radiology to evaluate the severity of conditions such as osteoporosis and to diagnose other bone-related conditions. This technique is also used in orthopedics to evaluate the health of bones and joints.

Types of Equipment Used in Calcium Scans
In a calcium scan, a special type of imaging technology is used to capture detailed pictures of the bones. This technology relies on various types of radiation detectors and imagers, as well as sophisticated software for image reconstruction and analysis. The accuracy of these systems depends heavily on regular calibration and maintenance to ensure reliable results.
Radiation Detectors and Imaging Modalities
The most common radiation detectors used in calcium scans are Single Photon Emission Computed Tomography (SPECT) and Positron Emission Tomography (PET) cameras. These scanners capture images based on the interaction between the radioactive tracers and the bone tissue.
– SPECT Cameras: SPECT cameras are widely used for bone scans, employing a sodium iodide (NaI) crystal for detecting gamma rays emitted by the radioactive tracer. They typically have a resolution of 3-5 mm.
– PET Cameras: PET cameras, on the other hand, use a ring of detectors and provide high-resolution images by measuring the coincidence of annihilation photons emitted when positrons annihilate with electrons in the body. Their resolution ranges from 2-5 mm.
– Gamma Cameras: Some gamma cameras, also known as Anger cameras, are used in calcium scans for their sensitivity to certain radiation energies. These cameras usually employ a NaI crystal and produce images with a resolution of 2-5 mm.
Imaging Modalities
These imaging modalities produce various types of images, each offering unique information about the bones.
– Planar Images: SPECT and gamma cameras produce planar images, also known as static images, which reflect the distribution of the radioactive tracer in the body.
– SPECT and PET Image Reconstruction: SPECT and PET cameras produce axial, sagittal, and coronal cross-sectional images through the process of image reconstruction, enabling the assessment of bone structures and their metabolic activity.
Software in Image Reconstruction and Analysis
Advanced software programs play a key role in reconstructing images from raw data obtained from SPECT and PET cameras. The primary algorithms used for image reconstruction include:
– Filtered Backprojection: This algorithm applies a filter to the raw data to enhance the resolution and reduce noise.
– Maximum Likelihood Expectation-Maximization (MLEM): This algorithm is an iterative approach used to reconstruct images with improved resolution and quantitation accuracy.
– Ordered Subsets Expectation-Maximization (OSEM): This algorithm provides faster image reconstruction compared to MLEM and is commonly used for PET images.
Equipment Calibration and Maintenance
Regular calibration and maintenance of SPECT and PET cameras are crucial for ensuring accurate results in calcium scans. Equipment calibration involves ensuring the detectors are properly aligned, the energy windows are correctly set, and the camera’s sensitivity and resolution are within acceptable limits. Maintenance includes tasks such as detector cleaning, software updates, and replacement of worn-out components, all aimed at preventing data corruption and ensuring high-quality images.
Common Misconceptions about Calcium Scans
