The latest scan of Israeli Prime Minister Ariel Sharon's brain showed slight improvement in his condition on Saturday but his life remained in danger three days after he suffered a massive stroke, doctors said according to Reuters. Shlomo Mor-Yosef, director of Jerusalem's Hadassah hospital, said the 77-year-old leader was still critical but stable after emergency surgery staunched bleeding in his brain. "We as human beings are optimistic," he told reporters in a news conference broadcast live throughout the Jewish state. "But I cannot say that the prime minister has come out of danger ... there are very slight signs of improvement." Mor-Yosef said a decision on when to try to awaken Sharon, who was in a medically induced coma, would be taken on Sunday morning and only then would doctors be able to assess how much damage he suffered from Wednesday's stroke. Results of the latest scan stirred cautious optimism in the Israeli media, but outside experts have said the prognosis for Sharon remains bleak given the haemorrhaging that led to his five-hour operation on Friday. The medical consensus is that if Sharon survives it is extremely unlikely he will ever return to political life, reported Reuters. --SP 21 06 Local Time 18 06 GMT
