Implantation and imaging of coronary stents

Abstract:
Percutaneous transluminal coronary angioplasty (PTCA) often is supplemented by the insertion of stents to prevent closing of the coronary arteries. This article reviews types of coronary stents and discusses the role that diagnostic imaging plays in their correct placement and determining their patency following implantation. The four primary diagnostic techniques used to image coronary stents--angiography, ultrasound, computed tomography and angioscopy--are discussed, along with the advantages and limitations of each.

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and solid...

Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for diagnosing...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
