    Background. This study determines when heterogeneous splenic enhancement patterns occur in contrast-enhanced CT in patients with and without liver cirrhosis. Patients and methods. Electron-beam CT of ... the abdomen was performedin 195 patients following intra- venous injection of contrast agent according to one of three injection protocols (protocol 1: n=132,120 ml, 2 ml/sec, scan delay: 50 sec; protocol 2: n=30, 90 ml, 3 ml/sec, scan delay:10 sec; protocol 3: n=33, 50 ml, 5 ml/sec, scan delay:10 sec). Thirty four of these patients had liver cirrhosis. Results. A heterogeneous splenic enhancement pattern was observed in 77% (protocol 2) and 65% (protocol 3) of the patients without liver disease and in 23 % (protocol 2) and 20% (protocol 3) of the patients with liver cirrhosis. A heterogeneous enhancement pattern was visible between 14 and 58 sec after the administration of contrast agent. In all patientgroups and protocols it never occurred later than 58 sec following the contrast agent application. Three patients had a splenic lesion (hemangioma, lymphoma, metastasis), these lesions were also visible after 58 sec following the injection. Conclusions. These results indicate that heterogeneous splenic enhancement patterns do not occur later than 58 sec after the contrast agent injection, even when the contrast agent is still being injected at that time.
