MRI scans cannot directly show anxiety or sleep disorder changes in Parkinson’s disease, but they can reveal brain structural and functional changes associated with these non-motor symptoms. Parkinson’s disease (PD) is primarily known for its motor symptoms, but anxiety and…
Magnetic Resonance Imaging (MRI) plays a significant and evolving role in diagnosing depression related to Parkinson’s disease (PD), a complex neurodegenerative disorder primarily known for its motor symptoms but also characterized by a wide range of non-motor symptoms, including depression.…
A CT scan of the sinuses is a specialized imaging test that uses X-rays to create detailed cross-sectional pictures of the sinus cavities in the face. This type of scan helps doctors diagnose sinus infections, inflammation, structural problems, or other…
A CT scan of the lungs typically involves exposure to ionizing radiation, but the amount of radiation varies depending on the type of CT scan performed. For lung cancer screening, a **low-dose CT scan** is commonly used, which significantly reduces…
A CT scan of the liver involves exposure to ionizing radiation, which is measured in units such as millisieverts (mSv) or milligray (mGy). The amount of radiation contained in a liver CT scan typically ranges from about 5 to 15…
A CT scan of the kidneys involves the use of ionizing radiation to create detailed cross-sectional images of the kidney structures. The amount of radiation contained in a kidney CT scan typically ranges around 5 to 10 millisieverts (mSv), though…
A CT angiogram is a specialized type of computed tomography (CT) scan that uses X-rays and contrast dye to visualize blood vessels in detail. It involves exposure to ionizing radiation, which is higher than that of a standard X-ray because…
A CT scan of the heart, often called coronary CT angiography (CCTA), is a medical imaging technique that uses X-rays to create detailed pictures of the heart and its blood vessels. This procedure helps doctors diagnose heart diseases, such as…
A CT scan of the spine uses X-rays to create detailed cross-sectional images of the vertebrae and surrounding tissues. This imaging technique involves exposure to ionizing radiation, which is higher than that of a standard X-ray but necessary to produce…
A single full body CT scan typically exposes a person to a radiation dose in the range of about **20 to 25 millisieverts (mSv)**, though this can vary depending on the scanner, protocol, and patient positioning. This dose is significantly…
