Diagnostic sonography (ultrasonography) is an ultrasound diagnostic imagining technique used for visualizing many of the body organs. Being a non-invasive procedure, ultrasonography is both painless and harmless to the patient.

According to the standards of the Polish Ultrasound Society:

• all diagnostic procedures must be performed by a qualified and certified sonographer;
• all ultrasound scans must be performed using appropriate sonographic scanners and transducer probes (depending on the nature of the examination) and follow mandatory procedures;
• each ultrasound examination must be concluded with a detailed description of all abnormalities detected, together with photographic records.
• Regardless of the medical referral information, every ultrasound test should also include a complete scan of the organs/ abdominal scan with a detailed assessment of the following structures:
  
  
• liver
• gallbladder
• bile duct
• pancreas
• spleen
• kidneys and adrenal glands
• urinary bladder
• prostate
• alimentary canal (stomach, intestine)
