Dr. Kevin McEnery, a leader in the field of diagnostic radiology at MD Anderson Cancer Center, will be joining Dr. Galati this week to give a consumers overview of radiology techniques.
The use of x-ray in the diagnosis and management of various disease states has never been more important than today. The quality of the images that are created by the various scans give physicians an upclose look into the body. Below is list of various scan that are available today, and when they may be needed.
Patients often go for scans that they are unfamiliar with. This discussion will add to your understanding of these scans, and the questions you need to ask.
CT Scan
A computerized axial tomography scan is more commonly known by its abbreviated name, CT scan or CAT scan. It is an x-ray procedure which combines many x-ray images with the aid of a computer to generate cross-sectional views and, if needed, three-dimensional images of the internal organs and structures of the body. A CT scan is used to define normal and abnormal structures in the body and/or assist in procedures by helping to accurately guide the placement of instruments or treatments.

MRI (Magnetic Resonance)
An MRI (or magnetic resonance imaging) scan is a radiology technique that uses magnetism, radio waves, and a computer to produce images of body structures. The MRI scanner is a tube surrounded by a giant circular magnet. The patient is placed on a moveable bed that is inserted into the magnet. Read more
Mammograms are probably the most important tool doctors have to help them diagnose, evaluate, and follow women who've had breast cancer. Safe and highly accurate, a mammogram is an X-ray photograph of the breast. The technique has been in use for about thirty years.

Chest X-Ray
A chest X-ray can help find some problems with the organs and structures inside the chest. Usually two pictures are taken, one from the back of the chest and another from the side. In an emergency when only one X-ray picture is taken, a front view is usually done. Doctors may not always get the information they need from a chest X-ray to find the cause of a problem. If the results from a chest X-ray are not normal or do not give enough information about the chest problem, more specific X-rays or other tests may be done, such as a computed tomography (CT), ultrasound, echocardiography, or MRI scan.

Ultrasound examination, also called diagnostic medical sonography or sonography, is an imaging method that uses high-frequency sound waves to produce precise images of structures within your body. These images often provide information that's valuable in diagnosing and treating a variety of diseases and conditions.

An angiogram is an X-ray test that uses a special dye and camera (fluoroscopy) to take pictures of the blood flow in an artery (such as the aorta) or a vein (such as the vena cava). An angiogram can be used to look at the arteries or veins in the arms, legs, chest, or belly.
PET scan
A positron emission tomography (PET) scan is a unique type of imaging test that helps doctors see how the organs and tissues inside your body are actually functioning.
