Diagnostic Imaging
We use various diagnostic imaging techniques to identify diseases and other conditions. These techniques include:

• General Radiography — General radiography refers to X-rays, also called plain films, which are a form of electromagnetic radiation, just like visible light. X-rays are used to generate pictures of the inside of the body. There are many types of X-rays used for specific parts of the body, such as the chest, teeth, skeleton, pelvis, and abdomen and so on. More information.
• Magnetic Resonance Imaging (MRI) — MRI is a non-invasive procedure that uses powerful magnets and radio waves to construct pictures of the body. These images, or slices, can be projected, stored in a computer or printed on film. More information.
• Magnetic Resonance Angiography (MRA) — Magnetic Resonance Angiography (MRA) uses magnetic resonance imagining (MRI) technology to obtain detailed images of the blood vessels, which helps to detect, diagnoses and aid the treatment of heart disorders, stroke and blood vessel diseases. The procedure is painless, and the magnetic field is not known to cause tissue damage of any kind.
• Computerized Tomography (CT) — Computed tomography (CT) is a method of body imaging in which a thin X-ray beam rotates around the patient. Small detectors measure the amount of X-rays that make it through the patient or particular area of interest. A computer analyzes the data to construct a cross-sectional image. These images can be stored, viewed on a monitor, or printed on film. More information.
• Computed Tomography Angiography (CTA) — Computed Tomography Angiography (CTA) uses computed tomography (CT) technology to visualize blood flow in arterial vessels throughout the body, from arteries serving the brain to those bringing blood to the lungs, kidneys, arms and legs. CTA is used to screen people for arterial disease, such as aneurysms and pulmonary embolism. The procedure is minimally invasive and most patients can have a CTA without being admitted to the hospital.
• Ultrasound — Ultrasound involves the use of high-frequency sound waves to create images of organs and systems within the body. More information.
• Nuclear Medicine — Nuclear medicine is a specialized area of radiology that uses very small amounts of radioactive substances to examine organ function and structure. It can also be used as a therapeutic approach to treat certain diseases. More information.
• Positron Emission Tomography — Positron emission tomography, also called PET imaging or a PET scan, is a non-invasive diagnostic test that combines the technologies of computed tomography (CT) and nuclear medicine. PET measures the metabolic activity of cells in the human body and is used in patients with certain conditions affecting the brain and the heart, as well as in patients with certain types of cancer. PET is unique because it produces images of the body's basic biochemistry or function and can detect changes or abnormalities, which may indicate that a person has certain diseases. More information.
• Radiofrequency Ablation is the method of choice for treating osteoid osteoma (a benign tumor of the bone). During this procedure the tumor is heated up for a period of approximately 6 minutes and thus abladed. This procedure is minimal invasive, is done on an outpatient basis and has a short recovery time. More information.

A highly trained and licensed professional, called a radiologic or nuclear medicine technologist, performs these imaging tests. The images generated by these tests may include pieces of film, such as X-rays, or more likely computer pictures that are viewed on a monitor. Once the images are ready, they are reviewed and interpreted by a specially trained medical doctor, a radiologist, who shares the findings with the patient's doctor, usually within one to two days of the procedure.

Interventional Radiology
Patients have access to interventional radiology techniques that use imaging technology to perform minimally invasive procedures with the help of devices such as needles, catheters, balloons and stents to open blocked blood vessels, block bleeding vessels, treat aneurysms, drain fluid collections, drain bile ducts and kidneys, perform biopsies, treat vertebral disc problems and many other conditions. There are two separate teams of experts: one team specializes in neuro-interventions and the other in all other interventions. More information.
