A single chest CT scan typically exposes a person to about **4 to 7 millisieverts (mSv)** of radiation, depending on whether contrast dye is used and the specific scanning protocol. A chest CT without contrast usually delivers around 4 mSv,…
CT scans are considered “radioactive” because they use ionizing radiation—specifically X-rays—to create detailed images of the inside of the body. This ionizing radiation has enough energy to remove tightly bound electrons from atoms, which can cause changes in cells and…
A CT scan, or computed tomography scan, does involve the use of **ionizing radiation**, which means it uses X-rays to create detailed images of the inside of your body. However, the radiation itself is not radioactive in the sense that…
Performing MRI scans on advanced Parkinson’s patients presents a unique set of challenges that stem from the complex nature of the disease, the physical and neurological state of the patients, and technical limitations of MRI technology itself. Understanding these challenges…
Tremors, which are involuntary rhythmic shaking movements, are a hallmark symptom of Parkinson’s disease, often most noticeable in the hands when at rest. When Parkinson’s patients undergo MRI (Magnetic Resonance Imaging) scans, the presence of tremors can indeed influence the…
Radiologists reduce motion artifacts in Parkinson’s MRI scans through a combination of advanced imaging techniques, patient preparation, and post-processing methods designed to minimize the impact of involuntary movements common in Parkinson’s disease. Motion artifacts occur when a patient moves during…
MRI scans for Parkinson’s patients who have pacemakers involve special considerations, but they can be safe under carefully controlled conditions. The safety depends largely on the type of pacemaker implanted, the specific MRI machine and protocol used, and the presence…
MRI scans can indeed show complications related to Parkinson’s surgery, particularly after procedures like deep brain stimulation (DBS), which is a common surgical treatment for Parkinson’s disease. MRI is a valuable tool for detecting and monitoring various postoperative issues that…
Magnetic Resonance Imaging (MRI) plays a crucial and multifaceted role in monitoring patients who undergo Deep Brain Stimulation (DBS), a neurosurgical treatment involving the implantation of electrodes deep into specific brain areas to modulate abnormal neural activity. MRI is indispensable…
Magnetic Resonance Imaging (MRI) scans have become a powerful tool in neuroscience and medicine, allowing us to peer inside the living brain without surgery. When it comes to Parkinson’s disease, a progressive neurological disorder characterized by motor symptoms like tremors,…
