Services
DiaTri has set up an actively managed Diagnostic Network of highly credentialed diagnostic facilities. We are
committed to ensuring quality for all of our clients and their patients. DiaTri’s full service diagnostic scheduling
network handles many different diagnostic procedures, including the following:
CT
Is a special radiographic technique that uses a computer to assimilate multiple X-ray images into a 2-dimensional cross-sectional image called a "slice" or "cut". This can reveal many soft tissue structures not shown by conventional radiography. Cuts may be 5 or 10 mm or more apart. Scans may also be "dynamic", in which the movement of a special type of dye injected into the body is tracked. The CT machine rotates 180° around the patient's body, sending out a pencil-thin X-ray beam at 160 different points. Crystals positioned at points opposite the beam pick up and record the absorption rates of the varying thickness of tissue and bone. These data are then relayed to a computer that turns the information into a picture on a screen. Using the same dosage of radiation as that of the conventional X-ray machine, an entire slice of the body is made visible with about 100 times more clarity.
MRI (Magnetic Resonance Imaging)
Is a special technique used to create images of internal structures of the body, particularly the soft tissue. A large magnet is used to polarize hydrogen atoms in the tissues and then monitors the summary of the spinning energies within living cells. MRI images are very clear and are particularly good for diagnosing parts of the brain and spinal cord, joints and pelvis. These scans may also be useful for detecting some cancers, or following their progress.
EMG (Electromyography)
Is a test which measures muscle response to nerve stimulation. It is used to evaluate muscle weakness, determine if the weakness is related to the muscles themselves or to a problem with the nerves that supply the muscles. Abnormal results may be seen in such diseases as disc herniation and bulge, carpal tunnel syndrome, alcoholic neuropathy, Guillain-Barre syndrome and a variety of peripheral nerve disorders.
Bone Scan
Is a Nuclear Medicine study of the skeleton. A radioactive substance is injected and the scan (taken a short time later) reads the distribution of the radioactivity within the bone.
Myelogram
Is a diagnostic evaluation of the spinal canal and the exiting nerve roots. After injection of contrast media into the spine under fluoroscopic guidance, images are captured denoting any abnormalities in anatomy. A CT scan follows this injection where detailed cross-sectional images are taken. Both sets of images compliment each other for evaluation of the area of interest.
Arthrogram
Is a diagnostic study of the joints within the body (i.e., shoulder, wrist, elbow, knee). Contrast material is injected into the joint under fluoroscopic guidance to visualize cartilage tears or ligament abnormalities. May be used in conjunction with a CT or MRI to offer added detail.
Discogram
Is a diagnostic examination of the intervertebral discs. Often used as a presurgical guide for spinal fusion candidates. MRI is normally conducted first to evaluate for degenerative discs. These discs are injected with contrast material to recreate the patient’s symptoms. This test is especially useful in spines with multi-level degeneration to isolate symptomatic versus asymptomatic discs.
NCV
A nerve conduction velocity test (NCV), is an electrical test that is used to detect nerve conditions. The nerve is electrically stimulated while a second electrode detects the electrical impulse. The distance between electrodes are used to calculate the speed of impulse transmission (nerve conduction velocity). A decreased speed of transmission indicates nerve disease. A nerve conduction velocity test is often done at the same time as an EMG in order to exclude or detect muscle conditions.
P.E.T. Scan
Positron Emission Tomography is a noninvasive diagnostic imaging procedure that assesses the level of metabolic activity and perfusion in various organ systems of the (human) body. A positron camera (tomograph) is used to produce cross-section tomographic images, which are obtained from positron emitting radioactive tracer substances (radiopharmaceuticals) such as 2-(F-18) Fluoro-D-Glucose (FDG), that are administered intravenously to the patient.
