To evaluate the role of computed tomography (CT) perfusion imaging in patients with hepatocellular carcinoma (HCC). Materials and methods: Seventeen patients (9 men, 8 women) with newly diagnosed HCC, proven by biopsy, were evaluated with 256-slice helical CT. Perfusion parameters of blood flow (BF), blood volume (BV), arterial perfusion (AP), portal perfusion (PP), and hepatic perfusion index (HPI) were calculated in the normal liver parenchyma and HCC samples. Results: A total of 21 histologically proven HCC lesions were evaluated from CT perfusion images. BF, BV, AP, and HPI values were shown to be significantly higher (P < 0.05) in the HCC lesions than in the normal liver parenchyma. Conversely, PP values were found to be significantly lower (P < 0.05) in HCC relative to liver parenchyma. Conclusion: CT perfusion imaging has the ability to evaluate tumor assessment, characterization, and neoangiogenesis in HCC.

Sclerosing angiomatoid nodular transformation (SANT) is a rare benign primary vascular lesion of the spleen. Its etiology is still debated. Radiological characteristics are less known, although there are some reports regarding histopathological features of SANT. A 21-year-old male patient was admitted to our hospital with fatigue, weight loss, and abdominal pain for 4 months. Physical examination, complete blood count, and biochemical parameters were unremarkable. Dynamic contrast-enhanced computed tomography (CT) of the abdomen was performed. A heterogeneous well-defined hyperdense nodular lesion 3 cm in diameter was detected during the arterial phase. The detected lesion was seen as isodense with the spleen …

We compared the weight of the prostate specimen extracted after radical prostatectomy with preoperatively estimated weights of the prostate by different imaging techniques. Materials and methods: Prostate weights were estimated by transabdominal ultrasonography (TAUS), transrectal ultrasonography (TRUS), and computed tomography (CT) preoperatively before radical prostatectomy. Prostatectomy specimens were weighed postoperatively and the actual prostate weights were calculated. Statistical analyses were done using 95% confidence intervals with repeated measurement analysis of variance and intraclass correlation coefficients. Results: Of the 163 patients enrolled in the study, the mean age was 64.2 ± 6.4 (range: 45 to 76) years. The mean postoperative prostate …
