And the old lady cries.
And the lonely children suffer.
Their mother's now alone.
Their fathers wont come home.
And the old lady cries.
And the old lady cries.
The gods were hungry.
And the gods weren't happy.
They had offered their jewellery
They had paid and prayed only.
But the stones know no mercy.
Their hunger must be appeased.
While the guilty run free.
The innocent are punished.
But the little girl asks.
Why were we punished?
What did we do wrong?
We would have followed
Had we been told
And the old lady cries.
Her son will not return.
Her faith will not rise
The stones, she will burn.
And the anger wont subside.
Like the waves killed her love.
Her revenge will come.
Her children she must save.
But her anger wont subside.

USGS: Warnings Could Have Saved Thousands in Asia
A warning center such as those used around the Pacific could have saved most of the thousands of people who died in Asia's earthquake and tsunamis, a U.S. Geological Survey official said on Sunday.
None of the countries most severely affected -- including India, Thailand, Indonesia and Sri Lanka -- had a tsunami warning mechanism or tidal gauges to alert people to the wall of water that followed a massive earthquake, said Waverly Person of the USGS National Earthquake Information Center.
"Most of those people could have been saved if they had had a tsunami warning system in place or tide gauges," he said.
"And I think this will be a lesson to them," he said, referring to the governments of the devastated countries.
Person also said that because large tsunamis, or seismic sea waves, are extremely rare in the Indian Ocean, people were never taught to flee inland after they felt the tremors of an earthquake.
Tsunami warning systems and tide gauges exist around the Pacific Ocean, for the Pacific Rim as well as South America. The United States has such warning centers in Hawaii and Alaska operated by the U.S. Geological Survey. But none of these monitors the Indian Ocean region.
The 8.9-magnitude underwater quake -- one of the most powerful in history -- off the Indonesian island of Sumatra devastated southern Asia and triggered waves of up to 30 feet high.
U.S. seismologists said it was unlikely the Indian Ocean region would be hit any time soon by a similarly devastating tsunami because it takes an enormously strong earthquake to generate one.
"That's really what has created all of these problems -- is that the earthquake is just so massive," said Dan Blakeman, a USGS earthquake analyst.
But Person said governments should instruct people living along the coast to move after a quake. Since a tsunami is generated at the source of an underwater earthquake, there is usually time -- from 20 minutes to two hours -- to get people away as it builds in the ocean

Report from RSNA: CTA nails down role of gold standard for pulmonary embolism
Whether it scans in four slices or 16, CT is the method of choice for detecting pulmonary emboli, researchers said at the RSNA meeting. Even four-slice technology boasts a negative predictive value greater than 99%, better than ventilation/perfusion (V/Q) studies or conventional pulmonary angiography.
Differences among four-, eight-, and 16-slice scanners appear marginal so far, but few data are available to solidify any claims of superiority for 16, except in speed. Researchers at Stanford University clocked lung scan times at 26.6 seconds for four-slice, 9.25 seconds for eight-slice, and 5.45 seconds for 16.
Dr. Alessandro Napoli and colleagues at Stanford reviewed CT studies for 1240 consecutive patients referred for suspected pulmonary emboli. Overall, 20% of cases were deemed positive, with 41% of emboli found in the segmental arteries, 27% in lobal regions, 17% in subsegmental arteries, and 15% on the main branches.
While there was no statistically significant difference in detection rates among the three generations of scanners, readers said that eight- and 16-slice studies yielded more and clearer diagnostic data. The 16-slice scanner may eventually prove better at finding subsegmental emboli, but only a small number of cases were included in the study.
If a CT study is negative, it is safe to forgo further examination. Researchers at the University of South Carolina conducted a metastudy of 14 published papers with 3283 patients who had undergone CTA to evaluate suspected pulmonary emboli, had negative findings, and had stopped anticoagulation therapy based on those findings. Fourteen developed fatal pulmonary embolism, 23 demonstrated nonfatal embolism, and 52 showed evidence of deep venous thrombosis during follow-up.
The studies produced 95% to 100% negative predictive value (NPV), with an average of 99.1%. NPV for mortality was 99.4%. Whether the CTAs were performed on single-slice or multislice CT made no significant difference. By comparison, conventional pulmonary angiography has an NPV of 98.4%, and V/Q studies average 88%.

Plain radiographs (often called "plain Xrays" - but you can't see the X-rays, only the images created by them) can be obtained using a variety of imaging methods, and they all require exposing the patient to X-Ray radiation. The image or picture is basically a shadow of the parts of the patient that absorb or block the X-Rays. The image can be collected on photosensitive film, on a digital imaging plate, or on a flouroscope. The image is a "photographic negative" of the object - the "shadows" are white regions (where the X-rays were blocked by the object). Plain radiographs ("plain films") are usually taken by a trained Registered Radiologic Technologist. The resulting films are then interpreted by the Radiologist to make a diagnosis.

This is a poem from the last century when x-rays were just discovered!!!!
