The study was undertaken to assess the CT density of the antibiotics solution. CT scan of six antibioticssolution-streptomycin, chloramphenicol, Na-penicillin, ampicillin, kanamycin and cefamezine-in concentration ofabout 33% (approximatly single dose of intramuscular injection) was performed, using plastic syringes. Variousconcentrations of striptomycin, chloramphenicol and Na-panicillin were also examined for evaluation of relationbetween concentration and the CT density of the antibiotics. In addition, relationship between CT number andmathematically calculated effective atomic number and electron density of the antibiotics was evaluated. Theresults are as follows; 1. The CT densities of all antibiotics reveal high density (CT number 80–150) inconcentration of single intramuscular injection dose. 2. CT number of striptomycin, chloramphenicol andNa-penicillin gradually increased with increase of concentration of the antibiotics, producing linear proportionto concentration, effective atomic number and electron density of the antibiotics. 3. Therefore, density ofantibiotics should be included in differential diagnosis when high density on CT scan is observed.

PURPOSE: The purpose of this study is to assess the usefulness of dynamic MR imaging after contrast enhancement with Gd-DTPA in the differential diagnosis of hepatic focal lesions. MATERIALS AND METHODS: The population consists of 22 cases of hepatocellular carcinoma, 44 cases of hemangioma, and five cases of metastasis. Diagnosis of hepatocellular carcinoma was made by surgery, fine needle biopsy, ultrasonography, CT and conventional angiography. Hemangioma was diagnosed on the basis of ultrasonography, CT, conventional spin-echo MRI and clinical data. Diagnosis of metastasis was done by fine needle aspiration biopsy. Dynamic and delayed images were obtained using 1.5T superconductive magnetom after Gd-DTPA(0.1mmol/kg) intravenous injection. Quantitative and qualitative evaluation was done for each lesion. RESULTS: Early contrast enhancement with rapid or gradual washout was noted in 15 lesions of hepatocellular carcinoma(68.2%) ;on the delayed images, no contrast enhancement was noted in 18 lesions(81. 8%). Peripheral contrast enhancement pattern was predominantly(86.4%) observed in hemangiomas during dynamic phase. On the delayed images, homogeneous and persistent contrast enhancement of masses were noted in all hemangiomas. Characteristic centripetal fill-in pattern was observed in 32 lesions of hemangioma (72.7%). Contrast inversion of masses during contrast enhancement study was noted in all hemangiomas, while continuous negative contrast was noted in hepatocellular carcinomas and metastases. CONCLUSION: Dynamic MR imaging after contrast enhancement with Gd-DTPA is an useful method in the differential diagnosis of hepatic focal lesions.
