This assists in visualization of specific organs within the body. Procedures include heart perfusion, bone, liver, lung and gall bladder scans. Some preparation may be necessary for these studies. Ultrasound Ultrasounds are done with high-frequency sound waves, which pass through the body and are reflected back, thus creating an image. Procedures include vascular flow, gynecological, abdominal, intraoperative and neonatal scans.
Preparation usually is required.
Fluoroscopy Real-time imaging is used to evaluate specific body areas and organs. Contrast agents such as barium are used to assist in visualizing anatomy. Fluoroscopy is used to study the upper gastrointestinal tract, lower gastrointestinal tract, esophagus and spine. A spinal scan is known as a myelography. Fluoroscopy also is used to assist in guiding catheter placement.
