“…Pulmonary arteries show a tree-like pattern, their branches course centrifugally and it was found that Doppler ultrasound was excellent in demonstrating blood flow present in the pulmonary vasculature (31,32). In the current study, the degree of impaired perfusion was closely related to the severity of lung necrosis (p value < 0.001).…”

Objective: To evaluate the role of color Doppler sonography in comparison with CXR and CT imaging in diagnosis of pneumonia in adults. Patients and methods: Thirty-one patients with clinical suspicion of pneumonia were assessed by chest radiography, CT and sonography. Quantitative and qualitative sonographic examination of lesions was performed using color Doppler imaging. The correlation between color Doppler and CT findings was determined. Results: Lung ultrasound showed high sensitivity (100%), specificity (93.8%) and diagnostic accuracy 96.8% in diagnosis of pneumonia. It detected air bronchogram in all cases, simple effusion in 18 cases and effusion with internal echoes in 8 cases. It was almost agreement with CT findings (K = 0.93). The sensitivity of chest X-ray was low (60%). It was moderate agreement with CT findings (K = 0.608). A significant changes were seen in flow pattern in comparison with severity of necrosis by CT (P value = 0.038). Majority of our cases reflected pulmonary arterial flow pattern that was found in 21 cases. Conclusion: Lung ultrasound with color Doppler imaging is highly accurate and valid alternatively in diagnosis of pneumonia. By qualitative and quantitative impedance measurement, pulmonary and bronchial arteries can be differentiated. The flow pattern of pulmonary arteries was an indicative of good outcome.

“…Ultrasound criteria alone do not suffice to discriminate between primary tumor, metastasis, post-stenotic pneumonia and abscess. CDI and CEUS are important tools in differentiation between malignant and benign pulmonary masses (Hsu et al 1998;Liaw et al 1993). CDI will reveal pathology in approximately 65% of peripheral malignant masses because of increased vascularity.…”

The value of ultrasound techniques in examination of the pleurae and lungs has been underestimated over recent decades. One explanation for this is the assumption that the ventilated lungs and the bones of the rib cage constitute impermeable obstacles to ultrasound. However, a variety of pathologies of the chest wall, pleurae and lungs result in altered tissue composition, providing substantially increased access and visibility for ultrasound examination. It is a great benefit that the pleurae and lungs can be non-invasively imaged repeatedly without discomfort or radiation exposure for the patient. Ultrasound is thus particularly valuable in follow-up of disease, differential diagnosis and detection of complications. Diagnostic and therapeutic interventions in patients with pathologic pleural and pulmonary findings can tolerably be performed under real-time ultrasound guidance. In this article, an updated overview is given presenting not only the benefits and indications, but also the limitations of pleural and pulmonary ultrasound.

“…Use of ultrasound (US) to guide pleural procedures is associated with a reduced rate of adverse events [6], and its routine use has recently been advocated for all thoracocenteses and ICC insertions [4]. Doppler US has been extensively used to examine the vascular supply of pulmonary and chest wall tumours [7,8,9], and its ability to specifically image the ICA has been established [10,11]. However, acknowledgement of this has not been wide-spread in the international community, as evidenced by its absence in a number of recent reviews [12,13,14].…”

Thoracic Ultrasound Demonstrates Variable Location of the Intercostal Artery

Background: Ultrasound (US) guidance is advocated to reduce complications from thoracocentesis or intercostal catheter (ICC) insertion. Although imaging of the intercostal artery (ICA) with Doppler US has been reported, current thoracic guidelines do not advocate this, and bleeding from a lacerated ICA continues to be a rare but serious complication of thoracocentesis or ICC insertion. Objectives: It was the aim of this study to describe a method to visualise the ICA at routine US-guided thoracocentesis and map its course across the posterior chest wall. Method: The ICA was imaged in 22 patients undergoing US-guided thoracocentesis, at 4 positions across the back to the axilla. Its location, relative to the overlying rib, was calculated as the fraction of the intercostal space (ICS) below the inferior border of that rib. Results: An ICA was identified in 74 of 88 positions examined. The ICA migrated from a central ‘vulnerable’ location within the ICS near the spine (0.28, range 0.21–0.38; p < 0.001) towards the overlying rib (0.08, range 0.05–0.11; p < 0.001) in the axilla. Conclusions: The ICA can be visualised with US and is more exposed centrally within the ICS in more posterior positions; however, there is a marked variation between individuals, such that the ICA may lie exposed in the ICS even as far lateral as the axilla. Future studies need to identify which patients are at risk for a ‘low-lying’ ICA to further define the role of US imaging of the ICA during thoracocentesis or ICC insertion.
