Abstract
The present-day approach in radiology to reveal liver tumors is with noninvasive techniques. Numerous investigations have shown that ultrasonography (US) and computed tomography (CT) with and without intravenous contrast enhancement give a high accuracy. Radionuclide scanning, previously the most common technique, has therefore become practically obsolete despite the fact that the relatively new single-photon emission tomography has improved the sensitivity and specificity. Magnetic resonance imaging (MRI) is improving in resolution and speed and may very well soon replace conventional CT as a complement to US [6, 7]. The invasive technique of angiography has also been replaced as a diagnostic tool for detecting tumors with one exception, i.e., highly vascularized lesions such as hepatomas and metastases of endocrine origin. In these latter cases, the noninvasive methods cannot compete with angiography in detecting small nodules.
