CT: First-Line Imaging Choice Of Physicians For Diagnosis Of Pulmonary Embolism
Computed tomography (CT), a highly accurate, readily available medical imaging technique, is the overwhelmingly preferred technique of emergency physicians and radiologists for the diagnosis of pulmonary embolism (PE), according to a study in the January issue of the American Journal of Roentgenology.
PE, the formation of a blood clot in the lung, is a life-threatening condition that requires prompt diagnosis and treatment. Medical imaging techniques such as CT, lung scintigraphy, and MRI are currently available to physicians to diagnose PE. "The purpose of our study was to assess the diagnostic approach to PE practiced by emergency physicians and advised by radiologists," said Saurabh Jha, MD, lead author of the study.
"The results of our study indicate that by a large margin, both emergency physicians and radiologists prefer CT in the diagnosis of PE. In imaging of pregnant patients to whom radiation is of concern, approaches differed," he said.
"CT is the nearly universal first-line imaging choice for the diagnosis of PE. This is not surprising considering its accuracy is well established," said Jha.
This study appears in the January issue of the American Journal of Roentgenology.
