蘭州大學第一醫院的醫師在1/31於期刊 Radiology 發表一名33歲女性病患感染


Thomas Jefferson University 的放射科醫師 Paras Lakhani 說如果不是因為







Lahkani 說這很重要，因為同樣的情形也曾發生在 SARS病患身上。





In a study released in the journal Radiology on Friday, a group of
researchers at The First Hospital of Lanzhou University presented two of the
woman's chest X-rays side by side.

The scans show white patches in the lower corner of her lungs, which indicate
what radiologists call "ground glass opacity."

"If you zoom in on the image, it kind of looks like faint glass that has been
ground up," Paras Lakhani, a radiologist at Thomas Jefferson University who
was not involved in the study but examined the images, told Business Insider.
"What it represents is fluid in the lung spaces."

The X-rays provide researchers a few new clues about the nature of the virus.

The scans show the new coronavirus looks similar to SARS and MERS
Coronaviruses are a large group of viruses that typically affect the
respiratory tract. They also cause pneumonia and the common cold. Symptoms of
the new coronavirus include a fever, chills, headaches, difficulty breathing,
and a sore throat.

Until December, it had never been seen in humans.

The novel coronavirus was first identified among a small group of people
exhibiting pneumonia-like symptoms in Wuhan, China, in December. The
33-year-old patient whose lungs are shown in the new x-rays works in Wuhan,
but had traveled to Lanzhou a day before her symptoms started.

"If you didn't know about this outbreak, you'd read the scan and you would
just say, 'Okay, this patient has pneumonia,' because that's the most common
thing we see," Lakhani said.

On its own, he added, ground glass isn't particularly helpful for identifying
a coronavirus.

"You can see it with all types of infections — bacterial, viral, or
sometimes even non-infectious causes," Lakhani said. "Even vaping could
sometimes appear this way."

But the researchers also noticed that the ground-glass patches extend to the
edges of the patient's lungs.

"That's something we don't often see," Lakhani said. "We saw that with severe
acute respiratory syndrome (SARS) and we saw that with Middle East
respiratory syndrome (MERS)."

Lakhani said scans of those viruses have "a lot of similar features" to the
images from the 33-year-old patient.

The scans show the virus getting worse after 3 days
The researchers also saw that the white patches on the woman's lungs were
more pronounced in the second image, taken three days after the first — and
further into her treatment. That helps rule out the possibility of pneumonia.

"Pneumonia usually doesn't rapidly progress," Lakhani said. "Typically, most
hospitals will treat with antibiotics and patients will stabilize and then
start to get better."

In the hospital, the 33-year-old woman in Lanzhou inhaled a protein used to
treat viral infections, called interferon. Lakhani guessed that doctors
probably also administered "supportive treatment," such as fluids, steroids,
or a medication to open the woman's airways. But she continued to get worse.

That's significant, Lakhani said, since the same thing occurred in SARS
patients.

The best way to diagnose the coronavirus isn't via X-rays, though — it's a
laboratory test, which involves taking swabs of saliva or mucus from a
patient's nose and mouth or testing phlegm they may cough up.

But the test isn't perfect, since it can only detect the virus when a person
is showing symptoms.
