Dual Energy CT in Clinical Practice: Fink, Christian, Reiser

To understand the strengths and the limits of this technology, a brief overview of theoretical basis of DECT will be provided. Specific attention will be focused on the interaction of X-rays with matter, on the principles of attenuation of X-rays in CT toward the intrinsic limits of CT can distinguish between tissues that differ in radiographic density by 1% or less. Third, CT scanning enables multiplanar reformatted imaging: scan data can be visualized in the transverse (or axial), coronal, or sagittal plane, depending on the diagnostic task. Dual-energy CT provides information about how substances behave at different energies, the ability to generate virtual unenhanced datasets, and improved detection of iodine-containing substances on low-energy images. 1. Introduction to Dual Energy CT Although dual energy CT (DECT) has only gained broader attention in the last years, the idea already dates back to the beginning of CT. The first clinical CT scan was done in 1971 on Hounsfield’s EMI head scanner and in 1975 the Siemens SIRETOM was introduced.

This gives dual energy CT additional advantages over standard CT for a wide range of tests and procedures (see benefits of dual energy CT below). Why would my doctor refer me to have this procedure? Dual-energy CT is a tremendous innovation in CT technology that allows creation of acquisitions at more than one energy spectrum and provides improved lesion detection and characterization, superior determination of material composition, reduction in dose of iodine, and more robust quantification. About Dual Admission It has never been easier to start your higher education at one of Connecticut's 12 community colleges and finish at Central, Eastern, Southern or Western Connecticut State University.

Driven by recent breakthroughs in the field of medical imaging, dual and multi-energy CT will play an instrumental role in the mass scanning and diagnosis of suspected cases of coronavirus.

The term “dual-energy CT,” or “DECT,” refers to CT that uses two photon spectra; therefore, DECT is sometimes also referred to as “spectral CT.” In clinical practice today, two different spectra are generated either by switching the voltage of one x-ray tube or by running two tubes at different voltages, and spectral information is gained from two absorption measurements with normal CT detectors. Dual and multi-energy CT would be essential in diagnosing affected persons, and curb the mortality rate. CT scans are commonplace in detecting lung cancer in the elderly having a history of smoking.

In this review article we have discussed the basic principles of single-energy and dual-energy computed tomography and their important physical differences which can cause 2015-08-01 Objective:To explore the application of dual CT dual-energy scanning in the differential diagnosis of benign and malignant pulmonary mass.Methods:72patients with pulmonary mass were selected for this study,including 40 lung cancer patients as study group and 32 patients with inflammatory lesions as control group.All 72 cases underwent dual CT dual-energy scanning.The mean volume CT value,dose Healthcare). The dual-source CT scanner is composed of two x-ray tubes and two corresponding detectors. The two acquisition systems are mounted on the rotating gantry with an angular offset of 90°/95° with regard to their kilovoltage and milliamperage settings. For dual-energy CT acqu isition, the tube voltages are set at high energy (140 kVp) 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. Dual Source CT Dual Energy spectral imaging allows you to cover large anatomical volumes at high speeds and low doses. Because you always get the widest spectral separation possible, you can quantify even the subtlest changes such as bone marrow defects.

Spectral information can also be resolved by layer detectors or quantum-counting detectors.
