Dynamic Contrast Enhanced MRI (MRS) And Its Uses

Optimum image quality, Less unsharpness compared to exposure 1, visual of bony tissue,fine detail of fibula lining superimposed over Tibia

It can allow doctors to simultaneously monitor patient vital signs and react to changes without taking off their eyes from the procedure or patient while performing surgery.

Through this sheath, a long, flexible, soft plastic tube called a “guiding catheter” is pushed. The tip of the guiding catheter is placed at the mouth of the coronary artery. The guiding catheter also allows for radio-opaque dyes to be injected into the coronary artery, so that the disease state and location can be readily assessed using real time X-ray visualization.

A section of a blood vessel will be taken from another part of your body. It is usually taken from the chest, arm, or leg. It will be used to go around (bypass) the blocked arteries of your heart.

Ionic, iodinated IV contrast is a contrast agent that is commonly used in radiology today. Most of the time iodinated contrast agents are used intravenously. Iodinated contrast agents contain iodine as the translucent element and other chemical components that make up its chemical structure. The parent structure that the contrast agent is from a carboxyl group in the form of benzoic acid, to which other chemical components or side chains are attached (Bontrager, 2014). Ionic, iodinated contrast media holds a positively charged side chain element called the cation. The cation is a salt, usually consisting of sodium, meglumine, or a mixture of both. These salts increase the solubility of the contrast media and make them have higher osmolality (Bontrager, 2014). The purpose of using

When you place an arterial tube into the femoral artery or vein and point it distal/toward the feet this supplies the leg and foot with solution.

1. Angioplasty: Kereiakes and Wetherill write that “angioplasty is a procedure in which a heart doctor inserts a balloon catheter over a thin wire across an artery. The balloon is inflated and compresses the plaque to clear the arteries of any blockage.”(p. 106-107).

Echocardiogram. A sound wave imaging picture that looks at your heart, its valves, and the largest artery that carries blood from your heart to your body (aorta).

Rationale: To provide fluid and electrolytes to patient, thus increase blood flow and nutrients in the body

artery or vein. The tube in this artery is connected to a mechanical pump that

• A catheter will be inserted into a blood vessel that carries blood away from the heart (arterial catheter). This catheter will be used to check blood pressure and get blood samples during the procedure.

In order to boost image resolution and enhance pathology perception, imaging proficiency customarily enrol contrast media. Usually contrast agents recently in use contain iodine, and are further specified as high osmolar contrast media (HOCM), low osmolar contrast media (LOCM), and isotonic contrast media (IOCM), cling to their osmolality relative to plasma. LOCM or IOCM commonly used in majority study. All HOCM agents are ionic, with an osmolality predominantly five to eight times that of plasma. The glomerulus with no tubular reabsorption or excretion instantly sieve the injected contrast media. For patient with normal renal consequence, contrast material within the plasma has a half-life of 1 to 2 hours and almost all will be evacuate within 24 hours. All iodinated contrast agents are dialyzable.

The technology that is being investigated is the PET scan. The PET scan functions as a result of the specific atomic properties of positrons which are subatomic particles that have the opposite charge of electrons but the same mass. The PET scanner detects these positrons which are emanated by the radioactive chemicals attached to a chemical the body naturally metabolizes (Positron Emission Tomography, 2014). The PET scan is used in the fields of oncology, neurology, and cardiology to determine the flow of blood, the functionality of the organs, the health of heart tissue, the movement of cancer, and so forth (Positron Emission Tomography, n.d.). This technology works by inserting the patient with a radioactive material through injection,

Contrast resolution is the ability to distinguish anatomic structures of similar subject contrast such as liver-spleen and gray matter-white matter. The actual size of objects that can be imaged is always smaller under conditions of high contrast that under conditions of low contrast.

The history of the use of contrast media for radiographic procedures started back in the 1920’s. Radiologists and scientists started developing and practicing with different concentrations of osmolality of this product for future examinations; this ended up
