X-rays are a type of radiation that are created using large amounts of electricity in a x-ray tube. X-rays are used in medical imaging much like a camera uses visible light to create an image. X-rays pass through the body and create an image on film based on how many x-rays get absorbed and how many pass through. The film is commonly referred to as an “x-ray”, but x-rays are actually the type of radiation used to make the image.
Images are obtained with patients lying down on a table which moves through a rotating x-ray tube. Multiple sequential images are obtained using x-rays that are reconstructed in slices to provide detail of internal organs. The tube can look much like a MRI scanner, but MRI’s usually take between 30 minutes to an hour, while CT scans only take a few seconds.
An imaging technique which uses sound waves to visualize anatomical structures in real time. This is done by converting electrical energy to a brief pulse of high-frequency sound energy that is transmitted into the patient’s tissues. The ultrasound transducer then becomes a receiver, detecting echoes of sound energy reflected from tissue.
A Doppler ultrasound is a non-invasive test that can be used to estimate your blood flow through blood vessels by bouncing high-frequency sound waves (ultrasound) off circulating red blood cells. A regular ultrasound uses sound waves to produce images, but can’t show blood flow.
Injection – This procedure is most often used in the shoulder, knee, or hip but may also be helpful in other joints. It is done to make sure the injection goes into the joint itself where it has a better chance of working, the needle for the injection is guided by imaging, most often by an ultrasound.
Biopsies- An ultrasound-guided needle biopsy is a procedure to obtain a tissue sample of an abnormality discovered on a radiology scan. This is one type of “image-guided” biopsy, which combines the use of ultrasound with either a Fine Needle Aspiration or Core Needle Biopsy
