When a person experiences internal bleeding, doctors often need to quickly and accurately identify the source and extent of the bleeding inside the body. One of the most common and effective tools for this is a CT scan, or computed…
A CT scan used to diagnose kidney stones typically exposes a patient to radiation in the range of about 3 to 10 millisieverts (mSv), depending on the protocol and machine settings. Standard non-contrast CT scans, which are the most common…
A CT scan for appendicitis typically exposes a patient to about **5 to 10 millisieverts (mSv)** of radiation, though this can vary depending on the specific protocol and equipment used. This amount is roughly equivalent to two to three years…
A CT pulmonary angiogram (CTPA) used to diagnose pulmonary embolism (PE) typically exposes a patient to a moderate amount of radiation, generally in the range of about 1 to 1.5 millisieverts (mSv). This dose can vary depending on the scanning…
When a person experiences a stroke, one of the first and most critical steps in emergency medical care is to perform a CT scan of the brain. This imaging test helps doctors quickly determine the type of stroke—whether it is…
A trauma CT scan involves the use of ionizing radiation to create detailed images of the body, typically to quickly assess injuries after an accident or severe trauma. The amount of radiation in such a scan varies depending on the…
A heart CT scan for calcium scoring, also known as a coronary artery calcium (CAC) scan, uses a very low dose of radiation, typically around **1 to 1.5 millisieverts (mSv)**. This amount is considered quite low in the context of…
A whole-body CT screening scan exposes a person to a significant amount of ionizing radiation, typically ranging from about 10 to 30 millisieverts (mSv), depending on the specific protocol and scanner used. This dose is much higher than that of…
CT colonography, also known as virtual colonoscopy, is a medical imaging procedure used to screen for colorectal cancer and other abnormalities in the colon. It uses computed tomography (CT) technology to create detailed cross-sectional images of the colon and rectum…
A low-dose CT scan for lung cancer screening uses a significantly reduced amount of radiation compared to a standard CT scan, typically delivering about 1.5 millisieverts (mSv) or less of radiation. This dose is roughly equivalent to the natural background…
