Thirty patients with primary hepatocellular carcinoma were studied by computed tomography (CT) and angiography. Tumor images on CT could be classified into four groups according to the differences between precontrast and postcontrast scans. In comparing the findings of angiography and CT, hypervascular tumor shadows on angiography were visualized as low(More)
Thirty-one patients with anomalous and/or pathological conditions in the duplication of the renal pelvis and ureter were studied in order to analyze the urographic findings. A segmental defect evident in the visualization was caused by the abscess of one of the poles in the kidney. In patients with hypoplasia of one of the poles, the other normal pelvis(More)
CT images were studied in five patients with hepatocellular carcinoma associated with obstruction of branches of the portal vein. Two were solitary tumors located near the porta hepatis and were seen as low density areas. In addition noncancerous areas with impaired portal drainage also had lower densities than normally perfused areas. In one instance,(More)
In this study, we explore the use of deep convolu-tional neural networks (DCNNs) in visual place classification for robotic mapping and localization. An open question is how to partition the robot's workspace into places to maximize the performance (e.g., accuracy , precision, recall) of potential DCNN classifiers. This is a chicken and egg problem: If we(More)
An experimental radiologic reporting system using oral presentations has been developed and tested. The rewritable and compact magneto-optical disk (MOD) is employed to store oral diagnostic reports together with read radiologic images. The MOD is 5.25 inches in diameter, has a 600 MB memory capacity, and is erasable, light and compact. Advantages of the(More)
