[Significance of diagnostic imaging for determining surgical indications in solid liver tumors].

Radiological imaging is essential for the differential-diagnostic appraisal and the assessment of size, number, and localization of neoplastic liver lesions. The results determine the decision for or against operation and the surgical strategy. Moreover, oncological contraindications against surgery are recognized by imaging procedures. Technical refinements of imaging comprise improved quality of ultrasound and of computed tomography and fast sequences in magnetic resonance imaging. Special investigational protocols and specific contrast agents for ultrasonography and magnetic resonance technique are highly relevant for clinical practice. The value of diagnostic procedures is demonstrated by our own experience. The differential use of imaging procedures, technical and methodological performance and the final diagnostic interpretation require a high standard of expertise. Diagnostic accuracy is limited by technical and biological factors.
