Presentation on theme: "Scanning the Human Body"— Presentation transcript:
1 Scanning the Human Body EQ: What types of scans can we use to study the human body and what do they tell us?An MRI Machine
2 I. Computerized Axial Tomography (CAT/CT) CT scanning adds many X-ray images with the aid of a computer to generate cross-sectional views of a patient's anatomy.CT scans are performed to analyze the internal structures of various parts of the body to view traumatic injuriesCAT Scans can be used to view injuries or abnormalities in the brain to determine how to treat people appropriately
4 II. Electroencephalogram (EEG) EEG’s use small flat metal disks (electrodes) attached to the head to monitor the electrical impulses within the brainInformation is taken down in a series of wavy linesThis test is often used to test for epilepsy or other brain disorders that are caused by misfiring of neurons within the brain
5 II. Electroencephalogram (EEG) WTH!!! I thought Mom said I was getting an Egg!!!
6 III. Magnetic Resonance Imaging (MRI) Uses a magnetic field and radio waves to create detailed images of the organs and tissues within your body.The magnetic field temporarily realigns hydrogen atoms in your body. Radio waves cause these aligned atoms to produce very faint signals, which are used to create cross-sectional MRI images — like slices in a loaf of breadAn fMRI (functional MRI) is used to detect activity (or lack thereof) in various parts of the brainIf a part of the brain is not functioning or not functioning well, then a person could have some disorders
8 IV. Positron Emission Tomography (PET) In a PET scan, radioactive dye is injected into the bodyThis dye will collect in your organs including the brainThe subject is placed into a tunnel-shaped scanning machine that takes pictures of the radioactive dye in the brainThis creates a 3D image of the brainThis scan is primarily used in psychology to find areas of the brain that are placated due to Alzheimer's or other ailments
