TCT-181: How to Use Dose Modulation Protocols to Reduce Radiation Doses of Cardiac CT Scan ?chi-square linear trendLate PleistoceneMIS 5Naracoorte CavesWe examined mammal occurrence and variability through the Late Pleistocene vertebrate fossil deposit of Grant Hall in Victoria Fossil Cave, Nara...
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...
The risk from X-rays comes from the radiation they produce, which can harm living tissues. This risk is relatively small, but it increases with cumulative exposure. That is, the more you are exposed to radiation over your lifetime, the higher your risk of harm from the radiation. There is...
A CT scan, however, comes in at about 10 mSy for an abdominal scan while a PET/CT scan exposes you to about 25 mSy of radiation. Here’s what happens. When the ionizing radiation passes through your body from X-rays or other sources, they cause electrons to be ejected, which leaves ...
Electromagnetic (EM) radiation, on the other hand, has no mass and travels in waves. EM radiation can range from very low energy to very high energy, and we call this span the electromagnetic spectrum. Within the EM spectrum, there are two types of radiation -- ionizing and non-ionizing....
Be Proactive: Book an Ezra Full Body MRI Scan TodayReferences Magnetic resonance imaging (MRI) has transformed medical imaging. This non-invasive test produces high-quality images of the body's internal structures without using harmful ionizing radiation1. Today, MRIs are the preferred method for ...
Common technical pitfalls, such as suboptimal postcontrast phase timing, and MRI-specific challenges like subtraction misregistration artifacts, can significantly reduce image quality and diagnostic accuracy. The use of hepatobiliary contrast agents introduces additional challenges including arterial phase ...
The prediction of absorbed dose, based on dosimetry from either the initial cycle or the first two cycles, offers a means to reduce the number of acquisitions in subsequent cycles. Two approaches have been proposed in the literature. Firstly, the cumulative absorbed dose is estimated based on th...
An abdominal CT scan image. (Image credit: Shutterstock) Duong said it's important to balance CT scan image quality with the amount of radiation exposure — a practice doctors call ALARA, or as low as reasonably achievable. There are a few ways to reduce radiation exposure, Duong said. For...
If you are selected to undergo surgery, it may be used in combination with chemotherapy or radiation therapy. Surgery is meant to remove the cancer from the body. The extent of the surgery will depend on how widespread the cancer has become. Plastic surgery may also be used to restore appea...
