Digital radiography represents one of the greatest technological advances in medical imaging over the last decade. The use of photographic films for X-ray imaging will be obsolete in a few years. An appropriate analogy is the replacement of typical film based cameras with modern digital cameras. Images can be taken, immediately examined, deleted, corrected, and subsequently sent to a network of computers.
The benefits from digital radiography are enormous. It allows DMI’s mobile units to operate filmless. The referring physician can view the requested image on a desktop personal computer, and the time lapse between study completion and reading by a radiologist is much shorter than with traditional film. The images are no longer held in a single location; they can be seen simultaneously by physicians who are miles apart. Unlike traditional mobile X-ray, since there is no developing of film, only one trip is necessary.
An electrocardiogram (EKG) is an electrical recording of the heart and is used in the investigation of heart disease. An EKG may be done as part of a routine physical exam or when there are questions about the working of a patient’s heart.
The test is performed by a technologist and only takes about 15 minutes to complete. DMI offers EKG services for both adult and pediatric patients. No appointment is necessary.
Holter monitoring is a simple, noninvasive tool for evaluating and managing cardiac symptoms in patients. Two electrocardiography leads are recorded over a 24 to 48 hour period. The data provides an in-depth representation of a patient’s cardiac condition during routine activities of work, sleep, and exercise.
Once collected, the ECG tracing is analyzed to identify a wide array of physiological events: disturbances in the electrical conduction of the heart, myocardial changes associated with ischemia and infarction, evaluation of treatment and drug therapies, and assessment of pacemaker and internal defibrillator function.
Ultrasound waves sent to the part of the body being examined are reflected, refracted, or absorbed at the interfaces inside the body. Echoes that return in this way carry information about the size, distance, and uniformity of internal organs. This is displayed on a monitor to create an ultrasound image. During abdominal sonography, a hand-held device called a “transducer” is placed on the area being examined and moved around. This transducer generates ultrasound and sends it through the body. It also detects the returning echoes and transmits them as electrical signals.
