Some physicians have become so enamored with this technology that they now indiscriminately order chest CTs for every case of pleuritic chest pain. Pulmonary embolism can be difficult to diagnose, especially in people who have underlying heart or lung disease. 1,2 Since the 1990s, CT pulmonary angiography (CTPA) has become the method of choice for imaging in suspected PE. [ 24 , 31 , 32 ] This study requires only a few extra minutes and allows "one-stop imaging" for PE and DVT. MRI contraindicated: CT without contrast or CT myelogram. Because DVT and PE are part of the same disease process, CT venography can easily be performed after CT pulmonary angiography, without the administration of additional contrast material. The one-stop CT examination for chest pain, the so-called "triple rule-out (TRO) protocol" used to diagnose acute coronary syndrome (ACS), pulmonary embolism (PE), and acute aortic syndrome (AAS) is increasingly being performed in many institutions equipped with 64-slice multi-detector CT (MDCT) or newer generation MDCT scanners. Or because the referring doctor only ordered the initial study as a regular CT must it also be coded as just a CT thorax w contrast? If you have problems with … reported that the quality of the images acquired with individualized contrast timing was no better than that of the images acquired with a fixed scan delay protocol in helical CT for the diagnosis of acute pulmonary embolism. endobj A radiologist may recommend an MRI of the chest subsequent to CT for further evaluation.

[ 24 , 31 , 32 ] This study requires only a few extra minutes and allows "one-stop imaging" for PE and DVT. MRI contraindicated: CT without contrast or CT myelogram. Because DVT and PE are part of the same disease process, CT venography can easily be performed after CT pulmonary angiography, without the administration of additional contrast material. The one-stop CT examination for chest pain, the so-called "triple rule-out (TRO) protocol" used to diagnose acute coronary syndrome (ACS), pulmonary embolism (PE), and acute aortic syndrome (AAS) is increasingly being performed in many institutions equipped with 64-slice multi-detector CT (MDCT) or newer generation MDCT scanners. Or because the referring doctor only ordered the initial study as a regular CT must it also be coded as just a CT thorax w contrast?
