The purpose of this study was to determine typical radiation dose levels to patients undergoing CT-guided interventional procedures. A total of 571 patients undergoing CT interventional procedures were included in this retrospective data analysis study. Enrolled patients underwent one of five procedures: ...
A CT scan uses what’s called “ionizing” radiation. It’s powerful enough to pass through your body to create clear images on a computer. This type of radiation could raise your chances ofcancerat some point in the future. But it’s important to remember that ionizing radiation is around...
Several studies estimated the hematological malignancies risk associated with CT scan radiation in children and young adults in large-scale national cohort12,13,14,15,16,17,18and case–control studies19,20. Although results of most individual studies12,13,17,20and a recent meta-analysis21suggest ...
hybrid iterative reconstruction (hybrid-IR) is often used, and the clinical usefulness of DLR should be compared with hybrid-IR. In the future, DLR may replace hybrid-IR as the mainstay; however, DLR must be able to r...

compare the actual mAs of a CT scan,radiation dose and image quality,and discuss the application value of DoesRight technology-based MSCT(Multi-slice CT) in personalized low-dose chest physical examination scan.Methods:The DoesRight technology uses the preset tube current as the debug baseline (...
For example, patients with precancerous symptoms or early symptoms that might prompt their physician to perform a CT scan, which may lead to the possibility of reverse causation. Until now, there is still uncertainty on whether ionizing radiation from CT scans can increase the risks of cancer....
Dental-CT: Image quality and absorbed radiation dose of different scan protocols. Purpose: To develop a scan protocol for dental-CT which guarantees good image quality at the lowest possible radiation dose. Methods: In an experimental in... C Schorn,H Visser,KP Hermann,... - ROFO -STUTTGART...
radiation, not an actual dose imparted uniformly to the whole body.As an illustration, a nuclear medicine technologist receives about 2 mSv a year to the total body; that whole-body dose was measured and recorded by a dosimeter worn by ...
It should now be possible to use a 13cm CBCT scan and a full-face stereophotogrammetry image during 3D orthognathic planning to reduce radiation exposure. 展开 关键词: 3D planning Cone beam Extended field of view Stereophotogrammetry Superimposition ...
