Medical Imaging & Clinical Research

Cardiac imaging

Cardiac imaging is performed to diagnose diseases of heart. A cardio radiologist performs and then interprets medical imaging to diagnose heart disease, leaky heart valves and defects in size and shape of the heart. Cardiac imaging techniques include coronary catheterization, echocardiogram, Intravascular ultrasound, Cardiac PET scan, Cardiac CT scan and Cardiac MRI.

Coronary catheterization is used to determine the patency and configuration of the coronary artery lumens.

Echocardiogram or Transthoracic echocardiogram uses ultrasonic waves for continuous heart chamber and blood movement visualization.

Intravascular ultrasound is also known as a percutaneous echocardiogram, it is an imaging method specially designed as long, thin, complex manufactured catheters attached to computerized ultrasound equipment to visualize the lumen and the interior wall of blood vessels.

Positron emission tomography (PET) is a imaging methodology for positron emitting radioisotopes. Mostly used for the researches. Appropriate radioisotopes of elements within chemical compounds of the metabolic pathways being examined. 

A coronary CT calcium scan is a computed tomography (CT) scan of heart, for the assement of severity of coronary artery disease.it looks for calcium deposition in coronary arteries, which narrows and increases the risk of heart attack.

Magnetic resonance imaging (MRI) scanning is a imaging methodology, it comprehensive exams including the quantitative assessment of size and morphology, function and tissue characterization in single sessions.
