RADIOLOGY
62 million CT Scans performed a year
Overview
X-Ray
X-Ray beams pass through the body to produce different images on a scan based upon density
Air in lungs shows up as black
Fat and muscles show up as different shades of grey
- Uses a magnetic field and radio waves to create detailed images of organs and tissues within your body
- This magnetic field temporarily realigns hydrogen atoms
- Noninvasive way to examine organs, tissues, and skeletal system
MRI
MRI Risks
Metal in your body may be a safety hazard.
Should avoid having an MRI test in case of;
- Metallic joint prostheses
- Artificial heart valves
- Implantable heart defibrillator
- Pacemaker
- Metal clips
- Cochlear implants
- Bullets or shrapnel or metal fragments
Pregnancy precautionary, effects of magnetic fields on fetuses aren't well understood.

MRI What to expect
The MRI machine creates a strong magnetic field around you, and radio waves are directed at your body. The procedure is painless. You don't feel the magnetic field or radio waves, and there are no moving parts around you.

Gadolinium, a contrast material which enhances the appearance of certain details may be injected through an intravenous (IV) line into a vein in your hand or arm.

An MRI can last up to an hour or more. You must hold very still because movement can blur the resulting images.
X-Ray
Risks
Many people worry about the radiation
Generally, the rays are equally as harmful as the everyday environment
Contrast
A feeling of warmth or flushing
A metallic taste
Lightheadedness,
Nausea,Itching,Hives
Rarely
Severe low blood pressure
Anaphylactic shock
Cardiac arrest
Types

X-Ray
Common Procedures, Benefits, Risks
Commonly Used For:
-Examines chest, abdomen, pelvis, and injuries with trauma
-Detects many different cancers (size, location, and damage to nearby tissues)
-Detects and treatment of vascular diseases that may lead to stroke or kidney failure
-Diagnosis and treatment of spinal problems and injuries to skeletal structures
Advanced CT-Scan
CT-Scan
Computed tomography or CT scan is an X- ray procedure that combines many X-ray images with the help of a computer that produces cross-sectional views or 3D images of the internal organs and structures of the body.
Department and System Interaction
Ultrasound
Why its used
Fractures, infections,arthritis, dental decay,
osteoprosis, bone cancer, lung infections, breast cancer, enlarged heart, blocked blood vessels.

American College of Radiology
The mission of the ACR Head Injury Institute (HII) is to bring together head injury specialists to advance research, prevention and treatment of head injuries through the application of diagnostic imaging

This group is very involved in research by collecting data to determine how different populatons of patients respond to head injury's
Focus on solidifying certain indicators to describe certain brian injuries to aid in diagnosis

iCT-Scan
Benefits
-Uses the least amount of radiation
needed
-Radiation based on patient's need
and location of the body
-Images and resoultion are optimized
-Recommended for children and young adults
Benefits:
-Fast and accurate
-Painless and noninvasive
-Minimal to no side effects
-Works with patients with implanted medical devices


Risks:
-Excessive exposure to radiation may cause cancer
-Not recommended for pregnant women or children
-Allergic reaction to the contrast material iodine

Radiologist are able to instanlty view scans.
This saves precious time
Medicaid is requiring use of EMR for full reimbursement
The Radiologist are able to get a better idea of why the patient is getting the scan
There are a variety of imaging tests that are out there to aid in diagnosis
Imaging has drastically changed health care
We will focus on CT Scan, Xray, MRI, and Ultrasound
Functions:
-Patient scheduling
-Examination interpretation
-Image storage
-Results distribution
-Procedure billing
The Radiology Info System works with PACS (Picture Archiving and Communication Systems) which is the creation and distribution of images within the imaging department and throughout imaging enterprise. Together they work with the EMR department to provide functions listed below.
