Seizure Imaging Explained: Distinguishing Generalized and Focal Seizures
Seizures are sudden, abnormal electrical disturbances in the brain that affect both motor and non-motor functions. They can range from a brief lapse in consciousness to convulsions that cause loss of body control. While many people associate seizures with dramatic convulsions, the condition is much more complex. The two primary types of seizures are generalized […]
Interpretation of brain CT scan report
Interpretation of brain CT scan report Tissue Density In a CT scan, different tissues have varying densities. Bones, due to their high density, appear bright white, whereas softer tissues such as the brain appear in shades of gray or black. Presence of Hemorrhage or Clots One of the most critical indicators in a brain CT […]
Understanding T1-Weighted MRI Images and Their Diagnostic Value
T1-Weighted MRI Images T1-weighted MRI images are one of the primary sequences used in magnetic resonance imaging to provide detailed anatomical views of the body. These images are characterized by their ability to differentiate between tissues based on their relaxation times, offering high-contrast visuals that are especially effective for highlighting fat and certain soft tissues. […]
Understanding AVM (Arteriovenous Malformation) Through MRI
What Is an AVM, and what does AVM (Arteriovenous Malformation) on MRIs look like? An arteriovenous malformation (AVM) is a rare and abnormal connection between arteries and veins, bypassing the capillary system. This tangle of blood vessels disrupts the normal blood flow, leading to potential complications in the affected area. AVMs can occur anywhere […]
Understanding FLAIR in MRI: Key Insights for Detecting Brain Abnormalities
Why FLAIR is essential in brain imaging FLAIR is essential in brain imaging because it enhances abnormalities’ visibility by suppressing cerebrospinal fluid (CSF) signals, which usually appear bright on MRI scans. This fluid suppression allows for clearer detection of lesions, inflammation, and other abnormalities the fluid’s brightness might otherwise obscure. FLAIR is particularly valuable in […]
