1. Pathology Digital Radiology
Techniques used in imaging

2. Why is technology so important
Why is technology so important? Prenatal Diagnosis and Management of Conjoined Fetuses

3. Traditional X-ray Uses electromagnetic waves to produce the image.
Must have film processor.
Films are hung on a view box to review by radiologist
Most traditional x-rays have been replaced with digital, but can be found in orthopedics and dentistry.

4. Digital Imaging
Uses computers to generate pictures of the internal body
Computers use mathematical information to make pictures
Advantages
No developing process or chemicals
Viewed on computer
Instant imaging
Can be transmitted via internet
Less radiation
Can be enhanced or manipulated

5. Digital Mammography Used for the diagnosis of breast cancer
Useful for patients less than 50 years old
Ultrasound can also be used to detect tumors and cysts

6. Ultrasound Uses high frequency sound waves to produce an image
Non invasive and causes no pain to patient

7. Computerized Tomography (CT scan)
Sends x-ray through the body to take a thin slice picture of the body part (cross-sectional)
Enhanced CT scans use injectable dye to produce image

8. Magnetic Resonance Imaging (MRI)
Produces images of soft body tissues
The image is produced by computer and a magnetic field
Uses no radiation

9. Positron Emission Tomography
Uses camera and radioactive drug to produce an image
Uses radioscope technology
The technique is most often used to locate cancers
Has also been used to study Alzheimer’s and Parkinson’s disease

10. Interventional Radiology
Invasive procedure using catheters and needles to perform such interventions as angioplasty, biopsies and stent placement using radiographic guidance
