[Value and reliability of blood pool scintigraphy in liver hemangiomas].

In a prospective study the importance and reliability of blood-pool scanning were checked. 40 patients were investigated. In 36 patients sonographical evidence of one or more hemangiomas was shown. 4 patients with 11 primary or secondary tumors in the liver were taken as control group. All tumors could be verified by histology or CT. Differentiation between hemangiomas and other space-occupying lesions (benign and malignant tumors) was possible with high accuracy. We found a sensitivity of 100% in hemangiomas larger than 4 cm, a sensitivity of 78% in hemangiomas larger than 3 cm and a sensitivity of 69% in hemangiomas larger than 2 cm. Falsely positive results were not observed. In conclusion, blood-pool scanning of the liver is a reliable method in the differential diagnosis of hemangiomas.

Extroversion and reminiscence following a frustrating paired-associate task.

Two experiments were reported relating extroversion to reminiscence following a frustrating paired-associate (PA) task. In the first experiment a group of 30 male and female college students was randomly assigned to one of two tasks in which they learned a PA list of high or low stimulus similarity. All PA lists were mixed lists composed of half solvable and half unsolvable (randomized) stimulus-response items. Recall for solvable items was tested immediately, 15 min, and 30 min after criterion was reached. Results indicated a significant difference between high and low stimulus similarity with superior recall for low similarity. The predicted reminiscence effect for high stimulus similarity recall was present but not significant. Comparison of recall scores for extroverts and introverts indicated a significant difference in recall favoring the introverts. The second experiment made a similar test of recall for two groups of S s that had been established as extreme extroverts or introverts (N = 8 in each group). The superiority of recall for introverts was replicated, and a reminiscence effect was found for the extroverts. Results were discussed in relation to Eysenck's formulation and previous conflicting results.
