What serous membrane surrounds the abdominal cavity and the abdominal organs?
Peritoneum
X-rays passing through the body onto film • Fewer rays pass through dense structures to reach film and show up lighter • Denser structures (bones) = lighter color, Less dense (spaces) = black • Everything will be shades of gray • Low radiation • Low cost
Radiography
Computer assisted radiography in which x-rays are directed in many different angles around a section of the body • Visualizes soft tissues • Creates flat slices through the body • Like X-ray denser structure = lighter color • Uses radiation • Higher cost
Computerized Tomography
Visualizes structures by recording pulses of
ultrasonic waves bouncing off tissues
• Cross sectional image viewed in real time
• Can demonstrate movement
• Doppler ultrasonography can detect velocity of
moving object – can be used for blood blood
flow
• Low cost
• No radiation
• Portable
Ultrasonography
• The machine uses a large magnet and a computer to take pictures of the inside of your body. Each picture or "slice" shows only a few layers of body tissue at a time. The pictures can then be examined on a computer monitor • Similar to CT images but better for tissue differentiation • No radiation • High cost
MRI Magnetic Resonance Imaging
Body is injected with radioactive isotopes - decay quickly, positrons are released • Areas with high number of positrons are more active • Good for showing high rates of activity: oxygen consumption, metabolism (FDGfluorodeoxyglucose) • High cost • Higher radiation • Lower resolution than fMRI
Nuclear Imaging
