ULTRASOUND (SONOGRAM):

An ultrasound is a diagnostic imaging technique used for visualizing subcutaneous body structures including lesions. Also referred to as Sonography (ultrasonography), this procedure is widely used in medicine. It is possible to perform both diagnosis and therapeutic procedures, using ultrasound to guide interventional procedures. This test is commonly conducted by a Sonographer. Sonographers are medical professionals who perform scans which are then typically interpreted by radiologists; physicians who specialize in the application and interpretation of a wide variety of medical imaging modalities, or by cardiologists in the case of cardiac ultrasonography (echocardiography). Sonographers typically use a hand-held probe (called a transducer) that is placed directly on and moved over the patient. Increasingly, clinicians (physicians and other healthcare professionals who provide direct patient care) are using ultrasound in their office and hospital practices, for efficient, low-cost, dynamic diagnostic imaging that facilitates treatment planning while avoiding any ionising radiation exposure.
