Before the scan, a patient is asked to inhale hyperpolarized xenon mixed with a buffer gas of helium or nitrogen ...
Modern detail-oriented scans such as high-resolution computed tomography (HRCT) is the gold standard in respiratory medicine and thoracic surgery for investigating disorders of the lung parenchyma . Contrasted CT scans of the chest are usually used to confirm diagnosis of for lung cancer and abscesses , as well as to assess lymph node status at ...
