The brain uses more energy than any other organ in the body. To sustain its functionality, a lot of blood has to be pumped towards it every second. When an artery in the brain bursts, a considerable amount of this blood can leak out and cause localized bleeding in the surrounding tissues.
Seizures, or the abnormal movements or behavior caused by unusual electrical activity on the brain, are one of the most common symptom of epilepsy. Not all people who’ve had seizures have epilepsy, though. For epilepsy patients, seizures happen twice or more in at least 24 hours apart, without any obvious triggers.
Given the slow-growing nature of prostate cancer and its lack of a high metabolic rate, PET scans are often seen as a poor imaging method for an accurate diagnosis. Back then, the lack of effective tracer drugs have hindered medical experts from using PET scans as a tool in detecting the patient’s prostate-specific antigen (PSA) […]
At first glance, MRI and CT scans may seem like the same thing. After all, they do both capture and process images of the body in line with the requirements of medical professionals. Although both procedures have the same end goal, there are several differences between an MRI and a CT scan:
Positron Emission Tomography (PET) is fundamentally used to diagnose illnesses ‘showing’ how the cells in the body are functioning. One of PET’s wide array of uses is in the diagnosis and treatment of Parkinson’s disease, a progressive degenerative disorder that negatively affects the motor or movement pathways in the brain.
Magnetic resonance Imaging (MRI) can be used to detect prostate cancer. Using MRI, a technologist can produce detailed pictures of the structures inside a man’s prostate, as well as its surrounding tissues. MRI is generally requested because it provides highly detailed images, however, certain factors can affect its quality, such as rectal distention.
