What is CT Angiography?
Angiography is a minimally invasive medical test that helps physicians diagnose and treat medical conditions. Angiography uses one of three imaging technologies and, in most cases, a contrast material injection is needed to produce pictures of blood vessels in the body.
Angiography is performed using:
x-rays with catheters
computed tomography (CT)
magnetic resonance imaging (MRI)
CT angiography uses a CT scanner to produce detailed images of both blood vessels and tissues in various parts of the body. An iodine-rich contrast...
What is a varicocele?
A varicocele is a varicose vein of the testicle and scrotum that may cause pain and shrinking of the testicles. In healthy veins of the scrotum, a one-way valve allows blood to flow from the testicles and scrotum back to the heart. In a varicocele, the one-way valve has failed resulting in pooled blood and enlarged veins around the testicle.
What is Varicocele Embolization?
The enlarged veins found in a varicocele can be treated using embolization. In embolization a small tube called a catheter is inserted in the groin area...
Diagnostic Ultrasound, also called ultrasound scanning or sonography, produces pictures of the inside of the body using sound waves. It involves the use of a small transducer (probe) and ultrasound gel placed directly on the skin. High-frequency sound waves are transmitted from the probe through the gel into the body. The transducer collects the sounds that bounce back and a computer then uses those sound waves to create an image. Ultrasound examinations do not use ionizing radiation (as used in x-rays), thus there is no radiation exposure to the...
