Body Imaging

Body imaging is an important tool in diagnosing various medical conditions and is most commonly employed in orthopedics to locate the injury, assess the severity and also in assessing the recovery post-treatment. Body imaging services offered by specialists at IRIS Radiology include computed tomography, digital radiography, MRI scan and ultrasound.

Computed tomography (CT) scanning is a noninvasive X-ray based imaging technique that produces cross-sectional images of the body that can be viewed on a computer or even printed. CT imaging differs from X-rays in that the internal structures are not superimposed and so can reveal more anatomical details. A CT scanner is a large machine in the shape of a box with a short tunnel in the center. You will be lying over an examination table that moves into and out of the tunnel while the X-ray tube located in the circular gantry rotates around you. Electronic X-ray detectors housed within the gantry measure the emitted X-rays and sophisticated computers make up a picture of the cross-sectional anatomy. Computed tomography is most accurate and can image bone, soft tissues and blood vessels at a time and also serves as an excellent tool to assist during interventional procedures such as needle biopsies.

Digital radiography is a recent advancement in medical imaging which uses digital X-ray sensors instead of a film to produce accurate images. This technology assures improved patient care along with better quality digital images. Digital radiography constitutes a system with components that include a digital image receptor, a digital image processing unit, an image management system, image and data storage devices, interface to a patient information system, a communication network and a display device with operated controls. Digital radiographs are stored in the form of digital data. Major advantage of digital radiography as compared with images recorded with photographic film is easy storage and speedy retrieval without affecting image quality.

Magnetic resonance imaging (MRI) is one of the basic imaging tools employed by the medical profession which has a unique ability to visualize all soft tissues and bony structures within the body with a combination of excellent spatial and contrast resolution. During an MRI scan the patient will be exposed to a very homogeneous magnetic field. Radiofrequency pulses stimulate the area of the body under investigation and information returned from that region is used to build up an image of the area that is being investigated. MRI imaging is a map of hydrogen ion concentrations within the body. Although MRI is considered to be an ideal diagnostic tool to diagnose various conditions, there are certain limitations for use. Patients having ferromagnetic objects within the body are not ideal candidates. Majority of orthopedic implants are non-ferromagnetic and perfectly safe in all MRI scanners. Possible contraindications include metal foreign bodies implanted within the eye, cardiac pacemakers and intracranial aneurysm clips.

Ultrasound imaging is a common diagnostic scan that uses painless high-frequency sound waves to produce images (sonograms) of organs, tissues, or blood flow inside the body. The scan involves a hand-held probe called a transducer that is placed directly on and moved over the body part to be diagnosed. A water-based gel is used to couple the ultrasound between the transducer and patient.
Over the past decade, the use of ultrasound in the field of orthopedic and sports injuries has increased rapidly. This is principally due to the significant technological improvements that have occurred over this time period. It is now commonly used to provide high resolution images of muscles, tendons and ligaments and provides an alternative to MRI in visualizing injuries to soft tissues.

A unique advantage of using ultrasound over other modalities is that a dynamic assessment of tendon, muscle or joint function can also be performed. Ultrasound is often used as therapeutic guide for injections to ensure optimal placement when this is indicated.
