A single mammogram exposes the breast to a very low dose of radiation, typically around **0.4 millisieverts (mSv)** or less. This amount is considered minimal and is roughly equivalent to the natural background radiation a person receives over about seven…
A heart ultrasound, also known as an echocardiogram, contains **no radiation** at all. Unlike imaging tests such as X-rays or CT scans that use ionizing radiation to create images, an echocardiogram uses **high-frequency sound waves** to produce pictures of the…
A breast ultrasound contains **no radiation at all** because it uses sound waves, not ionizing radiation, to create images of breast tissue. Unlike mammograms or X-rays, which rely on low doses of radiation to produce images, ultrasound technology works by…
A pelvic ultrasound contains **no ionizing radiation** at all. Unlike X-rays or CT scans, ultrasound imaging uses high-frequency sound waves to create images of the inside of the body, so it does not expose patients to radiation. This makes ultrasound…
Ultrasound imaging during pregnancy is a widely used and trusted method to monitor the health and development of the fetus. One of the common concerns expectant parents have is about radiation exposure from these scans. The key point to understand…
An **abdominal ultrasound contains no ionizing radiation** at all. Unlike X-rays or CT scans, which use ionizing radiation to create images, ultrasound imaging relies on high-frequency sound waves to produce pictures of the inside of the body. These sound waves…
A PET scan, or Positron Emission Tomography scan, is a medical imaging technique that allows doctors to see how tissues and organs in the body are functioning, rather than just their structure. This is particularly useful in diagnosing and monitoring…
A full-body PET scan involves exposure to a certain amount of radiation, primarily from the radioactive tracer injected into the body and sometimes combined with a CT scan for detailed anatomical imaging. The radiation dose from a PET scan alone…
A cardiac PET scan involves the use of a radioactive tracer to create detailed images of the heart’s function and blood flow. The radiation dose from a cardiac PET scan primarily comes from the radiotracer injected into the patient, which…
A PET scan, or Positron Emission Tomography scan, is a medical imaging technique widely used in cancer staging to detect the presence, location, and metabolic activity of cancer cells in the body. It works by injecting a small amount of…
