Specialized Imaging Modalities

Angiography

invasive procedure that demonstrates vessels by use of contrast

Arteriography

general term for visualization of arteries

Venograms

contrast study of veins

Interventional Radiology (IR)

refers to the repair of vessels by means of specialized catheters in conjunction with angiography

PTA

Percutaneous transluminal angioplasty and it uses a balloon to treat atherosclerosis

Stent

metal or plastic tube inserted to maintain patency of a vessel

Transcatheter embolization

prevents hemorrhage, reduces blood flow, or cuts off blood flow to a diseased area

CT

Computed Tomography and uses x-ray’s and computer technology to produce detailed cross-sectional images or slices of the body

MRI

Magnetic Resonance Imaging and noninvasive imaging modality that does not use ionizing radiation and uses a powerful magnetic feild and radiofrequency (RF) pulses

Ultrasound or Diagnostic Medical Sonography or DMS

Noninvasive procedure that uses high frequency sound waves and considered a very safe procedure with very low risks

Echocardiograms

ultrasound examination of the heart

OB Ultrasounds

Principle method for fetal imaging

Doppler Ultrasounds

Form of imaging that measures the speed and direction of blood flow

Nuclear Medicine (NM)

Medical use of radioactive isotopes and radiation is measured by gamma camera and it can be inhaled, ingested, and injected and. demonstrated physiological function of organ and tissues

Nuclear Medicine PET Scan

Positron Emission Tomography and is highly specialized NM technique and the radioactivity levels may be represented in colors on the monitor screen

Mammography

Procedure that uses special equipment to produce images of high contrast and high resolution to diagnose breast lesions and facilities have to be certified by FDA and ACR and Radiographers must pass specialized ARRT examination

Mobile Radiography

Portables

What are the cardinal rules of radiation protection?

Time, Distance, and Shielding

Surgical Radiography

Place x-ray tube under table to reduce head and neck exposure and protect sterile environment

Fluoroscopy Examinations of Esophagus or Barium Swallow

Radiographic exam of the pharynx and esophagus that studies the form and function or swallowing aspects

Fluoroscopy Examination of UGI

Radiographic examination that studies the form and function of the distal esophagus, stomach, duodenum. Can be done as a single of double contrast

Fluoroscopy Examinations for Small Bowel Series

Radiographic exam to examine the form and function of the duodenum, jejunum and ileum and the imiages are timed KUB’s

Fluoroscopy Examination for Barium Enima

Radiographic exam to examine the form and function of the large intestines and can be done as a single or a double contrast and barium bag should never be less or more than 18-24 inches above table height

IVU

Intravenous Urography is a radiographic exam or the urinary system and time images to visualize the collecting system and accesses the function ability of the kidneys and this is mostly done with CT scans now and also wait 5 minutes for allergic reaction
